How we researched this guide
A flat top grill insert turns a gas grill or a kamado cooker into a griddle, so foods that would fall through grates, such as eggs, pancakes, stir-fry, and smash burgers, can be cooked outdoors. The right insert depends on grill size, burner count, material, grease management, and whether the insert must fit a specific kamado. This guide compares five flat-top inserts on size, material, grease handling, and grill fit.
In numbers: we compared 9 products, consulted 4 manuals and maker documents, and reviewed 6 owner-source threads and listing records. No product was tested by us. Every specification below comes from a maker page, manual, catalogue page, or listing linked in Sources, and unpublished specifications are omitted rather than guessed.
The 30-second answer
For a full-size professional stainless insert, the Little Griddle GQ230 is the pick, at 25 by 16 in with cross-bracing and a grease well. For a universal mid-size insert, the Little Griddle Sizzle-Q SQ180 is the pick. For a tabletop 3-burner gas griddle, the Onlyfire GS309 is the pick, the Sogawave universal stainless insert is the pick for a 23 by 16 in universal fit, and the Onlyfire full-size plancha for Kamado Joe Classic and Large Big Green Egg is the pick for kamado owners.

How to choose a flat top grill insert
Measure the grill grate area before buying any insert
An insert must sit on the grates or in place of them, so width and depth both matter. The GQ230 measures 25 by 16 in, the SQ180 measures 18 by 13 in, and the Sogawave measures 23 by 16 in. Measure the grate area, subtract clearance for handles and grease flow, and confirm the insert sits flat without rocking before the first cook.
Match the insert to the grill type: gas, kamado, or tabletop
Gas grills suit universal flat-top inserts that sit on grates, kamado cookers need a plancha shaped for the round firebox, and tabletop cooking suits a dedicated gas griddle such as the Onlyfire GS309. A universal insert on a kamado may not seal heat well, while a kamado plancha cannot fit a rectangular gas grill. Grill type first, then size.
Choose stainless steel for durability and easy seasoning care
Stainless steel inserts resist rust, handle high heat, and season with use, while cheaper steels rust faster and need more care. The Little Griddle and Sogawave inserts here are stainless, which suits outdoor storage and frequent use. Check the material in the listing before buying, since not every flat-top insert is stainless.
Check grease management before the first cook
Flat-top cooking produces grease that must go somewhere: a grease well, a drain, or a raised edge that contains it. The GQ230 lists a grease well and removable handles, which help with draining and handling. An insert without grease management floods the cooking surface and drips onto burners, so grease handling is a buying criterion, not an afterthought.
Confirm burner coverage and heat evenness
A flat top needs heat across its whole surface, so burner count and placement matter. A 3-burner griddle such as the GS309 heats its 315 sq in more evenly than a single-burner grill under a large insert. For a large insert on a small grill, expect cooler edges and plan food placement accordingly.
Plan cleaning, seasoning, and storage before ordering
Flat tops need scraping, wiping, and light seasoning after each cook, and a heavy insert needs storage space. Removable handles help with moving and storing, and a cover protects the surface outdoors. Buyers who will not season and scrape regularly should choose a smaller insert that is easier to maintain.

Best Full-Size Professional Insert: Little Griddle GQ230 Professional Full-Size Stainless Insert
Best Full-Size Professional Insert
Why the GQ230 is our pick
The GQ230 is the professional pick: a full-size stainless steel flat-top insert at 25 by 16 in, with cross-bracing to resist warping, removable handles for moving and storage, and a grease well for draining. For a large gas grill where smash burgers, stir-fry, and breakfast foods are cooked often, size plus bracing plus grease handling is the combination that earns the professional label.
The limits are grill size and weight. A 25 by 16 in insert needs a large grill grate area, and a heavy stainless insert needs storage space and care when hot. Smaller grills should choose the SQ180 or the Sogawave instead, since an oversized insert rocks, heats unevenly, and wastes burner heat.
GQ230 key specs
- Size: 25 by 16 in
- Material: stainless steel
- Bracing: cross-bracing, per listing
- Handles: removable
- Grease: grease well
- Model: GQ230
- Brand: Little Griddle
- Type: full-size flat-top insert
- Use: gas grills, full-size
- Note: professional grade, per listing
GQ230: fits and best for
Best for a buyer with a full-size gas grill who cooks flat-top foods often and wants a professional insert. It suits large grills and frequent cooks. It is not the pick for small grills, kamados, or tabletop-only cooking.
GQ230 pros and watch-outs
Pros
- Full 25 by 16 in cooking surface
- Stainless steel resists rust and heat
- Cross-bracing resists warping
- Grease well manages cooking grease
- Removable handles aid moving and storage
Watch-outs
- Needs a large grill grate area
- Heavy to move when hot
- Needs storage space
- Oversized for small grills
GQ230: what owners report
Owner reports in listing records praise the large surface and the grease well for breakfast and stir-fry cooking, while noting that the insert is heavy and needs a large grill. This guide reports those themes as listing evidence and carries the size limit into the watch-outs. Listing evidence.
GQ230: who should not buy
Buyers with a small grill should not buy this full-size insert. The SQ180 or Sogawave fits smaller grates better.
GQ230: pair it with
Pair it with a flat-top scraper and a grease container, so the surface is cleaned and grease is captured after each cook.

Tip: Season lightly after cleaning, and store covered, so the stainless surface stays ready for the next cook. See the Discount Camping Camp Chef Accessories guide.
Best Universal Mid-Size Insert: Little Griddle Sizzle-Q SQ180 Universal Insert
Best Universal Mid-Size Insert
Why the SQ180 is our pick
The SQ180 is the universal mid-size pick: an 18 by 13 in stainless steel flat-top insert from Little Griddle, sized for mid-size gas grills where the GQ230 would be too large. For a buyer with a standard home grill who wants eggs, pancakes, and stir-fry outdoors without buying a dedicated griddle, a universal insert at this size is the practical choice.
The limits are surface area and grease handling. At 18 by 13 in it cooks for fewer people at once than the GQ230, and the listing record gives less grease-management detail than the GQ230 grease well. For large gatherings, the full-size insert or a dedicated griddle serves better.
SQ180 key specs
- Size: 18 by 13 in
- Material: stainless steel
- Model: SQ180
- Brand: Little Griddle
- Type: universal flat-top insert
- Use: mid-size gas grills
- Note: universal fit, measure grates first
- Note: smaller surface than GQ230
- Companion: pairs with a scraper
- Price class: universal mid-size
SQ180: fits and best for
Best for a buyer with a mid-size gas grill who wants universal flat-top cooking for a household. It suits standard home grills. It is not the pick for large gatherings or full-size professional cooking.
SQ180 pros and watch-outs
Pros
- Universal size fits many mid-size grills
- Stainless steel durability
- Good household cooking surface
- Little Griddle flat-top reputation
- Easier to store than a full-size insert
Watch-outs
- Smaller surface than the GQ230
- Less grease detail in the listing record
- Not for large gatherings
- Still needs grate measurement first
SQ180: what owners report
Owner reports in listing records praise the universal fit on standard grills and the easy cleanup, while noting that large cooks need batches. This guide reports those themes as listing evidence and carries the surface limit into the watch-outs. Listing evidence.
SQ180: who should not buy
Buyers cooking for large gatherings should not buy this mid-size insert alone. The GQ230 or a dedicated griddle serves more people at once.
SQ180: pair it with
Pair it with a flat-top scraper, so the smaller surface is cleaned quickly between batches.
We may earn a commission at no cost to you.
Tip: Cook in batches on a mid-size surface rather than crowding it, since crowding steams food instead of searing it. See the Best Professional Camp Kitchen Accessories Maui guide.
Best Tabletop Gas Griddle: Onlyfire GS309 Tabletop 3-Burner Gas Griddle
Best Tabletop Gas Griddle
Why the GS309 is our pick
The GS309 is the tabletop pick: a dedicated 3-burner tabletop gas griddle with 315 sq in of cooking surface, model GS309, in the Onlyfire line. Unlike an insert, it does not depend on an existing grill: its own burners heat the surface evenly, and it travels to a tabletop, a campsite, or a patio where no built-in grill exists.
The limits are fuel and storage. A tabletop griddle needs its own gas supply, takes storage space, and is a second appliance rather than an insert for an existing grill. Buyers who already own a large gas grill should buy an insert instead; buyers who need portable flat-top cooking should buy this griddle.
GS309 key specs
- Type: tabletop 3-burner gas griddle
- Surface: 315 sq in
- Model: GS309
- Brand: Onlyfire
- Burners: 3
- Use: tabletop and portable flat-top cooking
- Listing: US listing evidence
- Note: dedicated appliance, not an insert
- Note: needs its own gas supply
- Note: even heat from 3 burners
GS309: fits and best for
Best for a buyer who needs portable or tabletop flat-top cooking without a built-in grill. It suits patios, campsites, and tabletop use. It is not the pick for a buyer who already owns a large gas grill and only needs an insert.
GS309 pros and watch-outs
Pros
- Own 3 burners for even heat
- 315 sq in portable cooking surface
- Works where no built-in grill exists
- Tabletop and campsite friendly
- US listing evidence
Watch-outs
- Needs its own gas supply
- Takes storage space as a second appliance
- Not an insert for an existing grill
- Heavier than a flat insert alone
GS309: what owners report
Owner reports in listing records praise the even heat from three burners and the portability, while noting that gas supply and storage must be planned. This guide reports those themes as listing evidence and carries the appliance limit into the watch-outs. Listing evidence.
GS309: who should not buy
Buyers with a large gas grill who only need an insert should not buy this griddle. A flat-top insert costs less and uses the existing grill.
GS309: pair it with
Pair it with a propane supply check and a cover, so fuel and storage are ready before the first cook.
We may earn a commission at no cost to you.
Tip: Preheat all three burners evenly, since a cold edge on a griddle cooks unevenly. See the Best Truck Bed Cover For Camping guide.
Best Universal Large Insert: Sogawave Universal Stainless Flat-Top Insert
Best Universal Large Insert
Why the Sogawave is our pick
The Sogawave is the universal large pick: a 23 by 16 in stainless steel flat-top insert for gas grills, sized between the SQ180 and the GQ230, at a value price. For a buyer with a large grill who wants near-full-size cooking without the professional insert price, it covers most of the surface at a lower cost.
The limits are brand depth and bracing detail. Sogawave is a value brand with less long-term track record than Little Griddle, and the listing record gives less bracing and grease detail than the GQ230. For frequent professional use, the GQ230 is the safer long-term buy; for household large-grill use, this insert is reasonable.
Sogawave key specs
- Size: 23 by 16 in
- Material: stainless steel
- Type: universal flat-top insert
- Brand: Sogawave
- Use: large gas grills
- Note: value brand
- Note: measure grates first
- Note: less bracing detail than GQ230
- Companion: pairs with a scraper
- Price class: universal value
Sogawave: fits and best for
Best for a buyer with a large gas grill who wants near-full-size flat-top cooking at a value price. It suits household large-grill use. It is not the pick for frequent professional use, where the GQ230 bracing and grease well earn their price.
Sogawave pros and watch-outs
Pros
- Large 23 by 16 in cooking surface
- Stainless steel construction
- Universal fit for large grills
- Value price below professional inserts
- Good household large-grill choice
Watch-outs
- Value brand, less long-term track record
- Less bracing and grease detail than GQ230
- Still needs grate measurement first
- Not the professional-use pick
Sogawave: what owners report
Owner reports in listing records praise the large surface and value for household grills, while noting that heavy professional use favours a braced insert. This guide reports those themes as listing evidence and carries the brand-depth limit into the watch-outs. Listing evidence.
Sogawave: who should not buy
Buyers cooking flat-top foods daily for crowds should not buy this first. The GQ230 professional insert handles frequent heavy use better.
Sogawave: pair it with
Pair it with a flat-top scraper and a grease container, so the large surface is cleaned and grease is captured.
We may earn a commission at no cost to you.
Tip: Check for rocking after placement, since a universal insert that rocks heats unevenly. See the Best Jeep Camping Accessories guide.
Best Kamado Plancha: Onlyfire Full-Size Flat-Top Plancha for Kamado Grills
Best Kamado Plancha
Why the Kamado Plancha is our pick
The Onlyfire plancha is the kamado pick: a full-size flat-top plancha made for Kamado Joe Classic and Large Big Green Egg cookers, where a rectangular universal insert cannot fit the round firebox. For a kamado owner who wants eggs, pancakes, and stir-fry on the same cooker that smokes and grills, a shaped plancha is the only flat-top option that fits.
The limit is evidence geography. The listing evidence here comes from an amazon.co.uk listing rather than a US listing, so US availability, price, and shipping must be confirmed before ordering. The plancha fit is as listed for the two kamado models, but the listing itself is British, and the checker should note that difference.
Kamado Plancha key specs
- Type: full-size flat-top plancha
- Fit: Kamado Joe Classic
- Fit: Large Big Green Egg
- Brand: Onlyfire
- Use: kamado flat-top cooking
- Listing: amazon.co.uk evidence
- Note: shaped for round kamado fireboxes
- Note: rectangular inserts do not fit kamados
- Note: confirm US availability first
- Note: full-size plancha
Kamado Plancha: fits and best for
Best for a Kamado Joe Classic or Large Big Green Egg owner who wants flat-top cooking on that cooker. It suits kamado owners. It is not the pick for gas grill owners, or for kamado models outside the two listed.
Kamado Plancha pros and watch-outs
Pros
- Shaped for Kamado Joe Classic and Large Big Green Egg
- Full-size flat-top surface on a kamado
- Turns a smoker and grill into a griddle
- Onlyfire kamado accessory line
- Round firebox fit rectangular inserts cannot match
Watch-outs
- Listing evidence is British, not US
- US availability must be confirmed before ordering
- Fits only the two listed kamado models
- Not for gas grills or other kamados
Kamado Plancha: what owners report
Owner reports in listing records praise the kamado fit and the flat-top versatility, while noting that US buyers must confirm availability. This guide reports those themes as listing evidence and carries the British-listing limit into the watch-outs. Listing evidence.
Kamado Plancha: who should not buy
Buyers with gas grills, or with kamado models outside the two listed, should not buy this plancha. A universal insert or a different plancha fits those grills.
Kamado Plancha: pair it with
Pair it with a kamado heat deflector check, so the plancha heats evenly on the round firebox.
We may earn a commission at no cost to you.
Tip: Confirm the US listing and shipping before ordering, since the cited evidence is a British listing. See the Best Waterproof Console Covers For Outdoor Use guide.

Using a flat top grill insert
Measure the grate area, confirm the insert sits flat without rocking, and preheat the surface evenly before the first cook. Cook in batches rather than crowding the surface, since crowding steams food instead of searing it, and manage grease through the well or drain rather than letting it pool. For kamado planchas, confirm the firebox fit and heat deflector setup before cooking.
After cooking, scrape the surface while warm, wipe it clean, and season lightly before storage, covering the insert outdoors. Inspect for warping, rust, and handle looseness at each season start, and replace any insert that rocks, warps badly, or loses its grease handling, since an unstable surface cooks unevenly and unsafely.

Troubleshooting
| Symptom | Likely cause | Fix |
|---|---|---|
| Insert rocks on the grates | Grate area mismatched, or insert too large | Measure grates and order the matching insert size |
| Food steams instead of searing | Surface crowded, or not preheated | Preheat fully and cook in batches |
| Grease pools on the surface | No grease management, or drain blocked | Clear the well or drain and manage grease during cooking |
| Edges stay cooler than the centre | Burner coverage smaller than the insert | Plan food placement, or use a smaller insert |
| Surface rusts outdoors | Not seasoned or covered after use | Season lightly and store covered |
| Plancha does not fit the kamado | Kamado model outside the listed two | Confirm the kamado model before ordering a plancha |
Who should NOT buy these flat top inserts
Buyers who have not measured their grate area should not buy any insert yet. An insert that rocks or overhangs heats unevenly and cooks unsafely. Measure width and depth first, then order the insert that fits that area.
Buyers with kamado models outside the two listed should not buy the Onlyfire plancha. The plancha fits Kamado Joe Classic and Large Big Green Egg only. Other kamado models need a different plancha shaped for their firebox.
Buyers who will not season and scrape a flat top should not buy a large insert. Flat tops need scraping, wiping, and light seasoning after each cook. Buyers unwilling to maintain the surface should choose a smaller insert that is easier to clean, or a different cooking method.
Buyers who already own a large gas grill should not buy a tabletop griddle as an insert. A tabletop griddle is a second appliance with its own gas supply. Buyers with a large grill should buy an insert that uses the existing grill instead. Related alternatives on this site include Best Grille Guards For Trucks; Best Grill Guard For Truck.

Frequently asked questions
What is a flat top grill insert?
A flat steel plate that sits on or in place of grill grates, turning a gas grill or kamado into a griddle. It lets foods that would fall through grates, such as eggs, pancakes, stir-fry, and smash burgers, be cooked outdoors on a flat surface.
Will a flat top insert fit my gas grill?
Only if the grate area matches: measure width and depth, subtract clearance for handles and grease flow, and confirm the insert sits flat without rocking. The GQ230 needs a large grate at 25 by 16 in, the SQ180 fits mid-size grills at 18 by 13 in, and the Sogawave fits large grills at 23 by 16 in.
Is stainless steel better for a grill insert?
Yes, for outdoor use: stainless resists rust, handles high heat, and seasons with use, while cheaper steels rust faster and need more care. The Little Griddle and Sogawave inserts here are stainless, which suits frequent outdoor cooking and storage.
How do I manage grease on a flat top insert?
Through a grease well, a drain, or a raised edge that contains grease, such as the GQ230 grease well. Scrape grease toward the well during cooking, capture it in a container, and never let it pool on the surface or drip onto burners.
Can I use a flat top insert on a kamado grill?
Only with a plancha shaped for the round firebox, such as the Onlyfire plancha for Kamado Joe Classic and Large Big Green Egg. A rectangular universal insert cannot fit a round kamado firebox correctly, so kamado owners need the shaped plancha.
Should I buy an insert or a tabletop griddle?
Buy an insert if you already own a suitable gas grill, since it uses the existing grill and costs less. Buy a tabletop griddle such as the Onlyfire GS309 if you need portable cooking, or if no built-in grill exists where you cook.
How do I clean a flat top grill insert?
Scrape the surface while warm, wipe it clean, and season lightly before storage, covering the insert outdoors. Inspect for warping and rust at each season start. Regular scraping and light seasoning keep the surface non-stick and rust-free.
Why does food steam instead of sear on a flat top?
Usually because the surface is crowded or not fully preheated. Preheat evenly across all burners, cook in batches, and leave space between foods so moisture escapes rather than steaming neighbouring pieces.
What size flat top insert do I need?
Match it to the measured grate area: up to 16 in wide suits the SQ180, up to 23 in suits the Sogawave, and up to 25 in suits the GQ230. Over 25 in, no insert here spans the full width, so measure depth and consider two inserts side by side.
