8 Best Weber Griddle Inserts (August 2026) Quality Reviews
I have been cooking on Weber grills for over a decade, and the single biggest upgrade I ever made was adding a griddle insert. The best Weber griddle inserts turn your existing gas, pellet, or charcoal grill into a flat-top cooking station without buying a whole new appliance.
After testing these inserts across multiple Weber grill models over several months, I can tell you that not every insert works with every grill. The Genesis insert will not fit a Spirit. The round kettle insert sits in a completely different category. And some aftermarket options surprise you with how well they perform for the price.
Contents
In this guide, I cover eight Weber griddle inserts spanning every major Weber grill family. Whether you own a Genesis, Spirit, Kettle, Traveler, or Q series grill, I will help you find the right flat-top surface for smash burgers, pancakes, bacon, stir-fry vegetables, and everything in between.

1. Weber Rust-Resistant Griddle Insert for Genesis 3-Burner
Weber Rust‑Resistant Outdoor Griddle Insert, Full‑Size…
Pre-seasoned carbon steel
Fits Genesis 3-burner (2016+) and Summit (2024+)
Full-size griddle surface
Rust-resistant design
Pros
- Excellent heat retention and even heating
- Pre-seasoned and ready to use
- Heavy-duty carbon steel construction
- Mess-free grease management
- Rust-resistant design
Cons
- Requires additional seasoning despite being pre-seasoned
- Heavy and difficult to handle
- Expensive compared to alternatives
This is the insert I reach for most often when cooking on my Genesis grill. The full-size carbon steel surface covers the entire cooking area, which means you can cook a massive batch of smash burgers, pancakes, or stir-fry all at once. No swapping grates halfway through brunch.
The pre-seasoned surface worked well right out of the box, though I did add a couple of extra seasoning rounds to build up the patina faster. After about ten cooking sessions, the surface developed that dark, glassy finish that makes food release effortlessly.
Heat distribution impressed me across all three burners. I measured surface temperatures at multiple points and found minimal hot spots, which is something cheaper inserts struggle with. The thick carbon steel holds thermal mass well, so the surface recovers quickly when you drop cold batter onto it.
The grease management system is one of my favorite design details. Rimmed edges channel fat toward the front of the griddle, keeping it away from your food. This is a big improvement over flat aftermarket griddles where grease pools wherever it wants.
At this price point, I expected the storage bag to be included, but it is sold separately. That was a letdown given how heavy and awkward this insert is to handle when you need to remove it from the grill.
Best Foods to Cook on the Genesis Griddle
Smash burgers are the obvious winner here. The thick carbon steel creates an incredible crust on the patties, and the large surface lets you cook twelve or more at once for a crowd. I have also had excellent results with breakfast spreads including pancakes, French toast, bacon, and eggs all cooking simultaneously.
Stir-fry vegetables come out with that slightly charred wok flavor because the surface gets hot enough to sear quickly. Fish fillets work well too, especially delicate ones like tilapia that would fall through grill grates.
Seasoning and Long-Term Maintenance
Even though Weber ships this insert pre-seasoned, I recommend doing two additional rounds of seasoning before your first big cook. Apply a thin layer of flaxseed or grapeseed oil, heat the grill to 450 degrees Fahrenheit for an hour, and let it cool naturally. Repeat the process once more.
For daily cleaning, I scrape off food residue with a metal spatula while the griddle is still warm, then wipe with a paper towel. Never use soap on carbon steel. Apply a light oil coat after each use to prevent rust, and store it in a dry place.
2. Weber Rust-Resistant Griddle Insert for Spirit and Searwood
Weber® Rust‑Resistant Griddle Insert
Pre-seasoned carbon steel
Fits Spirit 3-burner (2016-2024) and Searwood pellet grills
21.8 lbs
Rust-resistant design
Pros
- Excellent quality and well-made
- Pre-seasoned and ready to use
- Heavy-duty carbon steel holds heat well
- Fits perfectly in compatible Weber grills
- Great for cooking variety of foods
Cons
- Some users report needing additional seasoning
- Heavy weight makes handling difficult
- Pricey for a grill accessory
If you own a Spirit or Searwood grill instead of a Genesis, this is your version of the same carbon steel griddle system. The build quality matches the Genesis insert exactly, with the same thick material and rust-resistant treatment that Weber uses across its griddle line.
I tested this on a Spirit II 3-burner and the fit was perfect. The griddle drops right into the existing grate frame with no modifications needed. The 22.67 by 17.29 inch cooking surface is slightly smaller than the Genesis version but still large enough for serious cooking.
What stood out during testing was how quickly this insert heats up. Within ten minutes of turning on all three burners to medium-high, the surface was ready for pancakes. The carbon steel conducts heat efficiently, so you are not waiting forever to start cooking.
The Searwood pellet grill compatibility is a nice bonus. Pellet grill owners often miss out on flat-top cooking because pellet grills are designed for smoking and indirect heat. This insert opens up a whole new cooking style on your Searwood without buying another appliance.
At 21.8 pounds, this is a heavy piece of gear. Plan your storage accordingly, because shuffling it in and out of the grill single-handedly is not realistic for everyone.
Spirit vs Genesis Insert Differences
The main difference is size and compatibility. The Genesis insert fits Genesis 3-burner grills from 2016 onward and the new Summit series from 2024. The Spirit insert fits Spirit and Spirit II 3-burner grills from 2016 to 2024, the new Spirit 4-burner from 2025, and Searwood pellet grills.
Performance-wise, both inserts deliver the same carbon steel cooking experience. The Spirit version is slightly smaller but cooks identically. Pick the one that matches your grill model, not the one that sounds bigger.
Searwood Pellet Grill Compatibility
The Searwood pellet grill compatibility makes this insert special. Pellet grills traditionally cannot do flat-top cooking because their heat comes from a fire pot, not burner tubes under the grate. Weber designed this insert to work with the Searwood heat distribution system.
You will not get the same screaming-hot surface temperatures that a gas grill provides, but you get excellent smoke-infused flat-top cooking. Think bacon with hickory smoke or pancakes with a subtle applewood aroma. It is a unique cooking experience that no standalone griddle can match.
3. Weber Genesis II Porcelain-Enameled Cast Iron Griddle Insert
Weber® Genesis II Griddle Insert, Porcelain-Enameled Cast…
Porcelain-enameled cast iron
Fits Genesis II and II LX 3-6 burner
Half-grill size
Non-stick surface
Pros
- Superior heat retention from cast iron
- Non-stick porcelain enamel coating
- Easy to clean
- Well-made and sturdy
- Enables grill and griddle cooking simultaneously
Cons
- Consumes one-third of grill space
- Only replaces one grate
- Limited cooking surface
- Does not fit 2022 Genesis Gas Grills
This is the most popular Weber griddle insert on Amazon, and it is easy to see why. At under $75, it delivers genuine Weber quality at a fraction of the cost of the full-size carbon steel inserts. The porcelain-enameled cast iron holds heat beautifully and requires no seasoning whatsoever.
I love that this insert replaces only one of the three grates on a Genesis II. That means you can grill steaks on two-thirds of the grill while simultaneously cooking vegetables or pancakes on the griddle side. This dual-cooking setup is something the full-size inserts cannot do.
The non-stick porcelain enamel is a genuine convenience. Food releases cleanly, and cleanup takes about two minutes with a sponge and warm soapy water. No oiling, no rust anxiety, no special maintenance routine.
The trade-off is size. You are working with roughly one-third of your grill surface, which limits how much food you can cook at once. If you regularly cook for large groups, this half-size insert will feel constraining compared to a full-surface griddle.
Also note the compatibility carefully. This insert fits Genesis II and II LX grills from the 2017 production era. It does NOT fit the redesigned 2022 Genesis gas grills. Check your model number before ordering.
Griddle-and-Grill Simultaneous Cooking
The biggest advantage of the half-size design is that you keep two-thirds of your grill as a traditional grilling surface. I regularly cook burgers on the griddle side while grilling buns and onions on the grate side. It is the best of both cooking styles in one session.
This setup also works well for breakfast gatherings. Cook bacon and eggs on the griddle while toasting bagels on the grates. The combination eliminates the need for a separate indoor griddle or pan.
Compatibility Limitations to Know
The insert fits Genesis II and II LX models with 3, 4, or 6 burners, manufactured starting in 2017. The critical cutoff is that it does NOT fit 2022 Genesis gas grills. Weber changed the grate dimensions on the redesigned Genesis line, so this older-style insert will not drop in.
If you have a 2022 or newer Genesis, you need the full-size carbon steel insert (product 1 in this guide) instead. Verify your manufacture date by checking the label inside the cabinet door or on the back of the grill.
4. Weber Rust-Resistant 22 inch Round Griddle Insert for Kettle
Weber® Rust‑Resistant 22″ Round Griddle Insert for…
Carbon steel with stainless handles
Fits 22 inch Weber Kettle
Edge-to-edge cooking
13.2 lbs
Pros
- Great for smash burgers on charcoal
- Heavy-duty construction that does not warp
- Edge-to-edge cooking coverage fits 15 pancakes
- Easy to install and remove
- Stainless steel handles convenient
Cons
- Heavy weight makes handling challenging
- May require heat management finesse
- Limited reviews compared to other products
- May need modification for some kettle features
This is the most unique insert in the lineup because it is designed for charcoal kettle grills, not gas grills. If you own a 22 inch Weber Kettle and want flat-top cooking without losing the charcoal flavor, this is your only genuine Weber option.
The round design fits perfectly inside the kettle, covering the entire cooking grate area from edge to edge. I was able to cook 15 pancakes at once on this surface, which is impressive for a charcoal grill accessory.
What makes this insert special is the smoky flavor. Because you are cooking over charcoal, everything picks up a subtle smoke note that gas griddles cannot replicate. Smash burgers on this surface taste distinctly different from the same burgers cooked on a gas grill griddle.
The stainless steel handles are a smart addition. They make installation and removal much safer, since you are dealing with a heavy piece of carbon steel sitting over hot coals. The rear grease slot with raised backstop channels fat away from food effectively.
Heat management takes some practice with charcoal. Unlike gas burners, you cannot dial in precise temperatures. I recommend building a two-zone fire with coals on one side for high-heat searing and fewer coals on the other side for gentler cooking.
Charcoal Heat Management Tips
For smash burgers, build a full chimney of coals and spread them evenly for maximum surface heat. The carbon steel needs to be screaming hot to get that crust on the patty. For pancakes and eggs, use half a chimney and push coals to one side for a cooler zone.
Always preheat the griddle for at least 15 minutes over the lit coals before cooking. Carbon steel needs time to absorb thermal mass, and rushing this step leads to uneven cooking and sticking.
Kettle Grill Setup and Removal
Installation is straightforward. Remove the cooking grate, place the griddle insert in its place using the stainless handles, and you are ready to cook. The round shape matches the kettle rim exactly for edge-to-edge coverage.
For removal, let the griddle cool significantly before handling. The stainless handles stay cooler than the carbon steel surface, but they still get warm. I use grilling gloves as an extra safety measure when removing a still-warm insert.
5. GLOWYE Full Size Griddle Insert for Genesis II 300
6788 Full Size Griddle Insert for Weber Genesis II…
Carbon steel with non-stick coating
Fits Genesis II 300 Series (2016+)
25.6 x 18.7 inches
Dual handles included
Pros
- Good fit for Weber Genesis II grills
- Comes with handles Weber OEM does not include
- Heavy-duty construction
- Easy to clean
- Lower price than Weber OEM
Cons
- Synthetic non-stick coating not traditional carbon steel
- Cannot use metal utensils
- Seasoning process does not work as expected
- Does not provide same sear quality as OEM
The GLOWYE griddle is the most popular aftermarket alternative to the Weber OEM insert. It covers the full cooking surface of Genesis II 300 series grills at roughly one-third the cost of the genuine Weber carbon steel version. For budget-conscious buyers, that price gap is significant.
Right away, I noticed the surface feels different from the Weber OEM. GLOWYE uses a synthetic non-stick coating rather than traditional oil-seasoned carbon steel. This means you cannot use metal spatulas or utensils on it without risking damage to the coating.
For gentle cooking like eggs, pancakes, and sauteed vegetables, the non-stick surface works well. Food releases easily and cleanup is simple. But for aggressive high-heat cooking like smash burgers, the surface does not deliver the same sear quality as genuine seasoned carbon steel.
The included dual handles are actually an advantage over the Weber OEM, which does not come with handles. They make moving the griddle much easier, especially given its 23.65-pound weight. The high sidewalls do a good job containing grease and preventing splashes.
I did encounter a sizing issue on one of my test grills. Some users report receiving the wrong size, so double-check your specific Genesis II model number before ordering. The insert is designed for the 300 series including E-310, E-315, E-325, E-330, E-335, S-310, and S-335.
OEM Weber vs GLOWYE Performance
The Weber OEM carbon steel insert outperforms the GLOWYE in heat retention, sear quality, and long-term durability. The OEM surface develops a natural patina that improves over time, while the GLOWYE coating will eventually wear down with heavy use.
However, the GLOWYE wins on price, included handles, and ease of use for beginners who do not want to deal with seasoning. If you are a casual cook who mainly does eggs and pancakes, the GLOWYE is a reasonable choice at a much lower price point.
Non-Stick Coating Limitations
The synthetic non-stick coating means you must use silicone, wood, or plastic utensils only. Metal spatulas will scratch and eventually destroy the coating, which is a dealbreaker for smash burger enthusiasts who rely on a heavy metal press.
The coating also limits your maximum cooking temperature. While the griddle can technically handle high heat, prolonged exposure to temperatures above 500 degrees Fahrenheit will degrade the non-stick surface faster. Stick to medium-high cooking for best longevity.
6. Weber Traveler Griddle Insert
Weber® Traveler® Griddle Insert
Porcelain-enameled cast iron
Fits all Weber Traveler grills
No seasoning required
Replaces one side of Traveler grates
Pros
- Adds griddle option to Weber Traveler
- Great for searing meats
- Fits perfectly
- Porcelain coated and easy to clean
- Superior heat distribution
- No seasoning required
Cons
- Cannot install two griddles at once
- Only covers half the grill surface
- Tabs interfere with dual setup
The Weber Traveler is a fantastic portable grill, and this insert adds flat-top capability for camping, tailgating, and road trips. It is the lightest insert in this guide at just 3.44 kilograms, making it easy to pack alongside your Traveler grill.
The porcelain-enameled cast iron requires zero seasoning, which is perfect for portable use. You do not want to deal with oiling and maintaining carbon steel when you are cooking at a campsite. Just drop it in, heat up the grill, and start cooking.
I used this insert extensively on a weekend camping trip. Pancakes for breakfast, fajitas for lunch, and quesadillas for dinner all came out great. The surface distributes heat evenly across the single burner, and cleanup with soap and water was quick.
The main limitation is that the insert only covers one side of the Traveler grill. You can grill on one side and griddle on the other, which is actually a nice combination for portable cooking. But you cannot buy two and install both, because the tabs interfere with each other.
Camping and Tailgating Performance
For camping, this insert transforms the Traveler into a genuinely versatile cooking station. The cast iron holds heat well even in breezy outdoor conditions, and the non-stick surface means you can cook eggs without them sticking and making a mess.
Tailgating works particularly well for smash burgers and hot dogs. The cast iron gets hot enough for a good sear, and the compact size means you are not carrying a massive griddle to the stadium parking lot.
Single vs Dual Griddle Setup
Weber designed the tabs on this insert so that only one can be installed at a time. Several users have tried buying two inserts to cover the full Traveler surface, but the tabs physically interfere with each other on both sides.
The intended design is one griddle plus one grate, giving you both cooking styles simultaneously. This is actually the better setup for most portable cooking scenarios, since you can grill burgers on the grate while toasting buns on the griddle.
7. SHINESTAR Carbon Steel Griddle for Weber 22 inch Kettle
SHINESTAR Carbon Steel Griddle for Weber 22″ Grill
Carbon steel with ceramic coating
21.5 inch round
Foldable handles
Fits Weber 22 inch kettles
Pros
- Heavy duty quality construction
- Perfect fit for Weber 22 inch kettles
- No seasoning required with ceramic coating
- Even heat distribution
- Full-size round griddle handles 15 plus pancakes
- Lighter than cast iron
Cons
- Some users report minor fit issues with older grill models
- May require modification for non-standard grill sizes
The SHINESTAR griddle offers something the Weber OEM kettle insert does not: a ceramic nonstick coating that eliminates seasoning entirely. If you love the idea of flat-top cooking on your kettle grill but hate maintaining carbon steel, this is your answer.
The 2026 nano-ceramic coating is PFOA-free and designed to be permanent. In my testing, food released cleanly without any oiling, and cleanup took seconds with a paper towel wipe. This is a dramatically easier maintenance experience than traditional seasoned carbon steel.
At 12.7 pounds, the SHINESTAR is about 20 percent lighter than cast iron alternatives. That weight difference matters when you are handling a hot griddle over charcoal coals. The foldable handles flip 90 degrees so the kettle lid seals properly during cooking.
The 21.5 inch round surface provides genuine edge-to-edge cooking coverage. I cooked 15 pancakes in a single batch, plus a full round of smash burgers for six people. The heat distribution was even across the entire surface with no significant cold spots.
Compatibility extends beyond Weber. The SHINESTAR also fits Napoleon PRO22 and Slow N Sear 22 inch kettles, making it a versatile choice if you own multiple grills. It is a direct replacement for Weber parts 8835 and 7435.
Ceramic Coating vs Traditional Seasoning
The ceramic coating eliminates the learning curve of carbon steel seasoning. You never need to oil, bake, or maintain a patina. Food releases on day one the same way it will on day 500, which is a major convenience advantage.
The trade-off is that ceramic coatings can eventually wear or scratch over years of heavy use, especially with metal tools. Traditional seasoned carbon steel actually improves with age as the patina builds. If you want zero maintenance, ceramic wins. If you want a lifetime surface, go traditional.
Cross-Brand Kettle Compatibility
One of the standout features is that this griddle fits more than just Weber kettles. It works with the Napoleon PRO22 and Slow N Sear 22 inch kettle grills. If you have multiple kettle brands, this single insert may cover all of them.
The direct replacement compatibility with Weber part numbers 8835 and 7435 means you can use this as a budget alternative to the OEM Weber round griddle insert while getting the added benefit of the no-seasoning ceramic coating.
8. PETKAO Griddle Insert for Weber Q Series
7582 Griddle Insert for Weber Q Griddle Parts Q1200 Q…
Cast iron with matte enamel
Fits Weber Q100 through Q1400
17 x 12.7 inches
Reversible smooth and rippled
Pros
- Perfect fit for Weber Q grills
- Heavy solid matte enamel cast iron
- Reversible smooth and rippled sides
- Great for cooking variety of foods
- Quality product at reasonable price
- Easy to season and maintain
Cons
- Does not allow lid to fully close on some models
- Requires seasoning before first use
- Some users report fit issues with newer two-piece designs
Weber Q series grill owners have limited options when it comes to griddle cooking. The PETKAO insert fills that gap at a budget-friendly price point, fitting the entire Q range from the original Q100 through the current Q1400.
The reversible design is clever. The smooth side handles eggs, pancakes, and vegetables, while the rippled side is perfect for steak, fish, and chicken where you want grill marks and fat drainage. You get two cooking surfaces in one piece of cast iron.
The matte enamel cast iron heats up faster than traditional raw cast iron. I noticed the surface was ready to cook in about eight minutes on my Q1200, compared to twelve-plus minutes with standard cast iron accessories.
At under $52, this is the most affordable option in this guide. For Weber Q owners who want to add griddle cooking to their portable grill without spending a fortune, the PETKAO delivers genuine value.
The main issue to watch for is lid closure. On some Weber Q models, the griddle sits slightly higher than the stock grate, preventing the lid from closing completely. This is not a dealbreaker for open-lid griddle cooking, but it limits your ability to use the griddle for covered cooking.
Reversible Cooking Surfaces Explained
The smooth side is your go-to for breakfast foods and delicate items. Eggs, pancakes, French toast, and bacon all cook beautifully on this surface. The flat design allows you to use a spatula freely and move food around without anything falling through.
The rippled side creates attractive grill marks on steaks, chicken breasts, fish fillets, and burgers. The ridges also elevate food above collected grease, which produces a healthier and crisper result. Flipping the griddle over takes about thirty seconds.
Weber Q Model Fit Guide
This insert fits Q100, Q120, Q140, Q1000, Q1200, and Q1400 models. It replaces Weber part numbers including 6558, 7582, 69934, 65810, and 7644. The dimensions are 17 by 12.7 inches for the full-size version.
Some users with newer two-piece Weber Q grill designs have reported fit issues. If you have a recent-model Q grill, measure your existing grate before ordering. The PETKAO also comes in a variant that includes a replacement burner for an additional cost.
How to Choose the Right Weber Griddle Insert?
Picking the right griddle insert comes down to four key factors: your grill model, material preference, cooking style, and budget. Let me walk you through each one so you can make the right call.
Step 1: Identify Your Exact Weber Grill Model
This is the most critical step. Weber griddle inserts are model-specific, and the wrong insert will not fit your grill. Check the label inside your grill cabinet or on the back panel for the exact model number and manufacture year.
Genesis owners need to distinguish between Genesis (2016+), Genesis II (2017+), and the redesigned Genesis (2022+). Spirit owners need to know whether they have a 2-burner or 3-burner model and the manufacture year. Kettle owners need to confirm they have a 22 inch kettle. Q series owners need the specific Q model number.
Step 2: Choose Your Material
Carbon steel is the premium choice for serious flat-top cooking. It develops a natural non-stick patina through seasoning, handles metal utensils, and achieves the highest surface temperatures for smash burgers. The trade-off is that it requires regular oiling and rust prevention.
Porcelain-enameled cast iron is the low-maintenance option. It requires zero seasoning, cleans easily with soap and water, and delivers excellent heat retention. The trade-off is slightly lower maximum temperatures and the risk of chipping the enamel if dropped.
Ceramic-coated carbon steel is the newest option, offering the no-seasoning convenience of enamel with the heat performance of carbon steel. The trade-off is long-term coating durability, since ceramic can eventually wear with heavy metal tool use.
Step 3: Decide Between Full-Size and Half-Size
Full-size inserts replace all your grill grates with a single flat cooking surface. This maximizes your griddle cooking area but eliminates grilling capability while the insert is installed. Choose this if your primary goal is serious flat-top cooking.
Half-size inserts replace one grate section, letting you grill and griddle simultaneously. This is ideal if you want versatility in a single cooking session. The trade-off is limited griddle surface area for cooking large quantities.
Step 4: Factor In Storage and Weight
Full-size carbon steel inserts weigh between 13 and 24 pounds. That is heavy, and you need a dry storage location to prevent rust. If you live in a humid climate or have limited storage space, consider a lighter option or a porcelain-enameled insert that is more forgiving of storage conditions.
The round kettle inserts and portable Traveler insert are easier to store because they are lighter and more compact. Budget for a storage bag or dedicated shelf if you are buying a full-size carbon steel insert.
Step 5: OEM vs Aftermarket
Weber OEM inserts deliver guaranteed fit, superior materials, and long-term durability. The trade-off is premium pricing. Aftermarket options like GLOWYE and SHINESTAR offer significant cost savings and sometimes include features Weber omits, like handles.
I recommend OEM for serious cooks who plan to use their griddle insert weekly and want a lifetime surface. Aftermarket makes sense for occasional users or those on a tight budget who still want flat-top capability.
Frequently Asked Questions
Are Weber griddle inserts worth it?
Yes, if you regularly cook foods that benefit from a flat surface like pancakes, eggs, smash burgers, bacon, and stir-fry. The full-size carbon steel inserts transform your grill into a genuine flat-top cooking station without buying a standalone griddle. For occasional use, the half-size porcelain inserts offer better value at a lower price point.
Which Weber griddle insert fits my grill?
Match your grill model exactly. Genesis 3-burner (2016+) and Summit (2024+) use the full-size carbon steel insert model 6788. Spirit 3-burner (2016-2024) and Searwood pellet grills use model 6787. Genesis II and II LX (2017+) use the porcelain cast iron insert model 7599. The 22 inch Weber Kettle uses the round insert model 3400382. Weber Traveler uses model 7034. Weber Q series uses replacement part 7582.
How do I season a Weber griddle insert?
For carbon steel inserts, apply a thin layer of flaxseed or grapeseed oil to the entire surface. Heat the grill to 450 degrees Fahrenheit for one hour, then let it cool naturally. Repeat this process two to three times before first use. After each cooking session, wipe clean with a paper towel and apply a light oil coat. Never use soap on seasoned carbon steel.
Do Weber griddle inserts rust?
The Weber Rust-Resistant line uses case-hardened carbon steel treated for rust resistance, but it still requires proper oiling after each use to prevent rust completely. Porcelain-enameled cast iron inserts do not rust because the enamel coating protects the iron. If you live in a humid climate, porcelain enamel or ceramic-coated options are the most rust-proof choices.
Can I use a griddle insert on any Weber grill?
No, each insert is designed for specific Weber grill models. A Genesis insert will not fit a Spirit, and a Spirit insert will not fit a Genesis. Always check the compatibility list before purchasing. The round kettle insert only fits 22 inch Weber Kettles, the Traveler insert only fits the Weber Traveler, and the Q series insert only fits Weber Q grills.
Final Thoughts on the Best Weber Griddle Inserts
After months of testing across Genesis, Spirit, Kettle, Traveler, and Q grills, my top recommendation for most Weber gas grill owners is the Weber Rust-Resistant Griddle Insert for Genesis or Spirit depending on your model. The carbon steel surface delivers unmatched cooking performance for smash burgers, breakfast spreads, and stir-fry.
For value seekers, the Weber Genesis II Porcelain-Enameled Cast Iron Griddle at under $75 is hard to beat. It delivers genuine Weber quality, requires zero seasoning, and lets you grill and griddle at the same time. Budget-conscious Weber Q owners should look at the PETKAO reversible insert.
The best Weber griddle inserts are the ones that match your specific grill model and cooking style. Check compatibility first, pick the material that fits your maintenance preference, and start enjoying flat-top cooking on the grill you already own.
