Our Picks at a Glance
How To Choose The Best Cast Iron Griddle For Gas Grill
Before you pick a griddle, you need to think about the gap between your grill’s cooking grates and what you want to cook. Three factors decide whether a griddle earns its spot on your grill: the physical size, the cooking surface, and the grease management system.
Measure Your Grill’s Cooking Area First
The most common mistake is buying a griddle that is too big for the grill. You want the griddle to sit securely on the grates without hanging over the edges where heat escapes. A 23″ x 16″ griddle is a popular large size for four-burner grills, while a 17″ x 9″ plate suits smaller two-burner models. Measure the flat space between your grill’s side walls before ordering, and remember some models list total length including handles, which can add a few inches.
Decide Between Flat, Reversible, or Enameled Surfaces
A flat-top griddle gives you one large, smooth cooking area for pancakes and eggs. A reversible griddle offers a smooth side for breakfast foods and a ribbed side for searing steaks with grill marks, but you only get half the cooking space per side. Enameled cast iron resists rust and needs no seasoning, while pre-seasoned or bare cast iron develops a natural non-stick layer over time but requires oiling and care. Bare cast iron also needs an initial seasoning before your first cook.
Check the Sidewalls and Grease Channels
High sidewalls, typically around 2.6 inches, keep oil and food from splattering across your grill and catching fire. Look for a grease trough or channel that funnels drippings away from the food and into a catcher, which prevents flare-ups and makes cleanup faster. Without a drain or deep trough, grease can pool on the surface and require careful wiping between batches.

In‑Depth Reviews
1. Onlyfire Pre-Seasoned Universal Cast Iron Cooking Griddle, 23″ x 16″
Our pick — over 4.5★ from 600+ verified ratings; the strongest balance of quality and price.
The crowd favorite that turns any four-burner gas grill into a full diner-style flat top.
With a cooking surface spanning 23″ x 16″ and walls rising 2.6 inches high, this is the griddle that handles a whole party’s worth of smash burgers or a full breakfast spread at once. The pre-seasoned cast iron distributes heat evenly without warping, and the high sidewalls contain oil and grease to keep your grill clean. Since it covers two full burners on most grills, you get even heating across the entire surface without cooler dead zones.
The dual side handles make it easy to lift and move while hot, and the pre-seasoned nonstick surface cleans up with a quick scrape rather than a deep scrub. Buyers report it “Fits the Camp Chef Everst II perfectly,” which hints at real-world fitment across popular grill brands. The main trade-off is the weight — at 10.56 kg it is a hefty piece of iron that takes two hands to manage, especially when you need to drain grease. A few owners note it is shallow for some burners, and the handles add roughly three inches, which can prevent it from fitting inside an oven for seasoning.
Why It Wins
- High sidewalls prevent grease spills and dangerous flare-ups
- Pre-seasoned nonstick surface resists sticking and is easy to wipe clean
- Fits most four-burner gas grills and stovetops
The Honest Trade-Offs
- At 10.56 kg, lifting and draining grease takes effort
- May be too shallow to fit all burner configurations
Reach for this if: you want one large pre-seasoned surface that feeds a crowd without flare-ups.
Think twice if: you have a smaller two-burner grill — this giant plate needs the width of a four-burner setup.
2. Lodge Reversible Cast Iron Grill/Griddle Pan, 16.75 x 9.5 Inches
The legendary American brand serves up two cooking surfaces in one 9.4-pound plate.
Lodge builds this 16.75″ x 9.5″ reversible plate to cover two burners, and its real genius is the dual-sided design. Flip it to the smooth side for pancakes and eggs, or flip it over to the ribbed side to get those sear marks on steaks and burgers. Made in the USA from pre-seasoned cast iron, it is naturally nonstick, PFAS-free, and non-toxic, so you skip the chemical coatings entirely. Its 0.75-inch thickness retains heat well, holding temperature long after the flame drops.
Owners consistently praise its versatility across gas, electric, induction, and even campfire cooking, and it works beautifully right on a gas grill. The honest catch is the weight: at 9.4 pounds it is heavy enough that one buyer returned it, noting it was “a little too heavy for me,” even while admitting “It’s perfect for the grill.” The low profile edges suit flat foods well, but for greasy cooks you will want a skillet with deeper walls, and the center can run cooler than the ends, which actually works nicely as a cool zone for keeping food warm.
The essential takeaway: a proven double-sided workhorse from the most trusted name in cast iron, ideal if you want both grill marks and a flat top without storing two pans.
Pick this if: you want one reversible plate that works on any heat source from your gas grill to a campfire.
Look elsewhere if: you need deep sidewalls for greasy cooks or a surface wider than two burners.
3. Utheer 23″ x 16″ Cast Iron Griddle for Gas Grill and Stove Top Flat Top
The enameled giant that laughs at rust and shrugs off warping at high heat.
If you love the 23″ x 16″ cooking area but dread the maintenance of bare cast iron, this Utheer griddle delivers the same massive surface with a durable enameled coating that resists rust and wear. X-shaped reinforcement ridges underneath keep the plate flat and stable at extreme temperatures, preventing bending or deformation over years of use. Owners mention even heat distribution with no hot spots, ensuring flawless searing across the entire surface.
Cleanup is genuinely quick: the nonstick enamel surface lets food slide off with less oil, and a simple wipe-down handles most of the mess. Multiple owners note it fits their grill perfectly and handles several items simultaneously, from smash burgers to salmon. The trade-off is weight and size — at 11.41 kg it is a serious piece of iron, and one buyer admits it is “very heavy and difficult to clean” without a giant sink. It works on gas grills, charcoal grills, and four-burner range ovens, making it a true all-in-one plate for backyard and kitchen use.
What owners love: the enamel coating makes post-cook maintenance simple — scrape or wipe the grease and you are done.
The fair warning: measure your grill first, and have a plan for washing a plate this size.
Choose it for: rust-free enameled convenience with the largest cooking footprint and warp-proof ridges.
skip it if: you need something light enough for solo lifting or you lack a large cleaning space.
4. SearCook Cast Iron Griddle for Gas Grill and Stove Top, 23″ x 16″
A mirror finish flat top that makes smash burgers and whole pizzas on the grill easy.
This SearCook griddle uses enameled cast iron across a 23″ x 16″ cooking surface with a food-safe, eco-friendly coating free of harmful chemicals. The enamel finish provides a smooth nonstick release with minimal oil, so delicate foods like fried eggs and french toast lift off cleanly. It fits most gas grills, charcoal grills, and four-burner stovetops, and customers note using it on Traeger pellet grills too, getting a proper sear on steaks that pellet grills alone cannot achieve.
Owners have cooked everything from grilled chicken and pineapple to smash burgers and even pizza on this plate, and they call the cleanup easy. X-shaped reinforced ridges on the underside resist warping, while the 12.79 kg weight provides thermal mass for consistent heat. One owner drilled two 1/4-inch holes in the grease valley to let drippings fall through to the grill’s grease catcher — a useful hack that hints at the only real downside: grease can pool if you cook large, fatty batches. This surface maxes out at 400 °C, so it handles high-heat searing without complaint.
The standout promise: no more hot spots or rust — the enameled coating delivers even searing and years of use.
Perfect for: cooks who want a low-maintenance enameled surface that fits a wide range of grills and pellet smokers.
Not ideal if: you cook huge quantities of fatty meats — you may need to drain the grease valley mid-cook.
5. onlyfire Universal BBQ Griddle with Handles for Most Grills, 18″ x 12.5″
The ceramic-coated griddle you can use straight from the start — no seasoning ritual required.
Most cast iron griddles demand an initial seasoning session before first use, but this onlyfire plate skips that step entirely. The premium ceramic coating on the cooking surface delivers excellent non-stick performance and easy cleaning from day one, with no need to build up layers of oil. Measuring 18″ x 12.6″ with sidewalls rising 2.8 inches, it gives you a generous cooking area for pancakes, bacon, burgers, eggs, or fried rice while keeping food from sliding off the edges.
The 7cm raised sidewalls and integrated grease trough work together to funnel drippings away and prevent flare-ups, making cleanup quick. Owners say it fits perfectly on their outdoor grill and is “soooo easy to clean” thanks to the grease pit that catches runoff. The dual side handles make it simple to lift during cooking, and the ceramic coating adds corrosion resistance for longer durability. At a mid-range 18-inch size with a 500 °F max temperature, it is a smart fit for typical three-burner grills where a 23-inch plate would overhang.
The core appeal: skip the seasoning learning curve and get straight to cooking with a corrosion-resistant ceramic surface.
Best for: grillers who want nonstick convenience without the upkeep of traditional bare cast iron.
Consider another if: you need a full 23-inch cooking surface for very large gatherings.
6. BBQ Future Universal Cast Iron Griddle for Gas Grill with Spatula Set, 23″ x 16″
A full 23 x 16-inch flat top that comes with its own spatula kit, ready to convert any grill into a Blackstone-style cooker.
This BBQ Future griddle pairs a large 23″ x 16″ pre-seasoned cooking surface with a three-piece stainless steel spatula set, so you have everything you need to start cooking immediately. Forged at high temperatures using traditional techniques, this cast iron heats up faster and more evenly than typical plates. The thickened inner walls resist deformation, and the full-width grease trough effectively prevents flare-ups while keeping the cooking surface clean.
Owners call it “better than a frying pan,” noting you can cook multiple pancakes at once, toast buns on a clean surface, and cook scrambled eggs with no grease. The pre-seasoned, specially treated surface is nonstick, rust-resistant, and scratch-resistant with no chemical coating, so food releases easily. The honest trade-off is the 12.76 kg weight — it delivers excellent heat retention for searing with minimal temperature loss, but cleaning requires some effort to manage the heavy plate and burnt fat. One owner sanded off the rough factory finish and re-seasoned it for a smoother surface, a sign that a bit of prep improves the experience.
What You Get
- Comes with a 3-piece stainless steel spatula set included
- High sidewalls and grease trough prevent flare-ups and splatter
- Pre-seasoned, rust-resistant surface needs no chemical coating
Points To Know
- At 12.76 kg, expect a serious workout when moving it
- Factory surface may need light sanding and re-seasoning for best release
Reach for it if: you want a complete griddle-and-spatula package with a huge cooking area and a built-in grease tray.
Look further if: you want enameled rust-proof convenience — this one needs traditional cast iron care.
7. 2-in-1 Reversible 14” x 16” Pre-Seasoned Cast Iron Cooking Griddle
A reversible two-burner plate with a recessed design that drains fat for healthier, faster cooking.
Measuring 16″ x 14″, this reversible griddle gives you a smooth side for eggs, pancakes, and bacon, plus a ridged side for searing steaks, burgers, fish, and chicken. The pre-seasoned cast iron heats up fast and evenly, cooking food quicker than normal pans—reviewers point out whole chickens with crispy skin and no burning. The recessed design lets fat drain downstream for a more delicious and healthy meal, and it works across gas stoves, ovens, grills, charcoal, electric, and campfires.
What owners love most is its versatility as a daily-use plate, whether for omelets in the morning or reverse-seared Picanha at 700 °F on a gas grill. It fits most two-burner propane gas stoves, though the size gets mixed feedback — some find it perfect while others note it may not cover larger grills completely. At 4.87 kg it is lighter than the 23-inch giants, making it easier to handle and store, and a light oiling with peanut oil keeps it rust-free between uses.
The practical edge: the reversible design means you never choose between breakfast eggs and dinner sear marks — you get both in one plate.
Choose it for: compact two-burner grills where you want both a flat top and a ribbed grill surface.
pass on it if: you need a larger surface for a four-burner grill — consider the 23-inch options above.
8. GGC Cast Iron Reversible Griddle
A solid 10-pound reversible plate sized right for small Weber gas grills and camp stoves.
This GGC griddle offers a 17″ x 9″ cooking area within a 20-inch total length that includes side handles, making it an excellent match for smaller gas grills where larger plates would overhang. Made from 100% solid cast iron with a matte coating and 0.6-inch thickness, it distributes heat evenly and retains it well, keeping the original flavor of your food. The reversible design gives you a ribbed side for steak, chicken, lamb chops, and roasted brussels sprouts, plus a flat side for pancakes, eggs, bacon, and fajitas.
Owners highlight how it fits small Weber gas grills perfectly and works great on Coleman stoves for road trips and camping. One owner praised it for cooking salmon perfectly with three filets fitting comfortably, adding that it eliminates the indoor fish smell entirely. Note that this griddle is not pre-seasoned, so you need to season it with vegetable or linseed oil before the first use, and avoid metal utensils to protect the surface. The 500 °F max temperature gives you plenty of range for serious searing.
The takeaway: a compact, heavy-duty reversible plate that punches above its size for small grills and camp stoves.
Made for: owners of small Weber gas grills, Coleman stoves, and anyone who camps and wants a solid cast iron surface.
Not for: large family cooks needing more than a 17″ x 9″ cooking area, or those who want a pre-seasoned ready-to-use plate.
9. 17″ x 13″ Cast Iron Flat Top Griddle – Oil Coating Non-Toxic – Universal Grill Insert
A budget-friendly 17″ x 13″ flat top with hollow side panels that promote even airflow and heating.
Designed to fit most gas, charcoal, and electric grills, this BLUES GRILL PARTS griddle comes with an oil coating that resists warping, withstands high temperatures, and helps prevent rust during shipping. The 17″ x 13″ cooking area handles eggs, bacon, shrimp, steak, vegetables, and teppanyaki all at once, making it a solid pick for breakfast, lunch, dinner, camping, and tailgating. The high-bar sidewalls prevent splatters and grease spills, while the integrated grease groove collects excess oil for healthier cooking.
The hollowed side panels promote airflow for even heating, and owners love that it turns a grate-style grill into a flat cooking surface for smash burgers — one called it perfect for a birthday party cookout. The main caveats surface in a few reviews: the plate does not come pre-seasoned, so you need to season it before first use, and one owner reported rust developing after a month despite regular oiling. The grease management also gets mixed feedback, with one buyer frustrated by the lack of a drain. That said, the quality and easy cleaning win most owners over, and it cleans up easily while cooking food evenly.
The honest read: a capable, affordable flat top for grate-style grills, but it demands proper seasoning and oil care to avoid rust.
Pick this if: you want an affordable universal flat top for smash burgers and you already know basic cast iron care.
Pass if: you want a pre-seasoned ready-to-use surface or a proper grease drain — this one has neither.
Understanding the Specs
Pre-Seasoned vs. Bare vs. Enameled Cast Iron
Pre-seasoned cast iron arrives with a factory-applied layer of oil baked into the surface, giving you a natural nonstick finish that improves with use. Bare cast iron needs an initial seasoning at home before first cook, which means coating it with oil and heating it to build the protective layer. Enameled cast iron has a glass-like coating fused to the surface that resists rust and needs no seasoning, making it the lowest-maintenance option but also the most expensive.
Why Weight and Thickness Matter
Cast iron works by absorbing heat and radiating it back evenly, which is why heavier plates ranging from 10 to 13 kg hold temperature better than thin steel alternatives. Thick walls, usually 0.6 to 2.6 inches, prevent warping under high heat and give you a consistent sear across the whole surface. The trade-off is maneuverability: heavier griddles need two hands and a plan for cleaning, while lighter ones are easier to lift but may develop hot spots.
