Transforming your backyard gas grill into a proper pizza oven is one of the most satisfying upgrades you can make. The direct, intense heat of a gas burner—combined with a cordierite stone—lets you achieve the charred, leopard-spotted crust that defines Neapolitan-style pizza, something your kitchen oven simply cannot replicate without a dedicated stone setup and a long preheat cycle. The trick is finding the right attachment or conversion kit that locks that heat in and directs it onto the pie.
I’m Mohammad Maruf — the founder and writer behind AirfryerBite. I’ve spent years analyzing the heat retention materials, airflow designs, and temperature tolerances of every major grill-top oven and conversion kit on the market, focusing on the raw specs that separate a crisp crust from a burnt bottom.
Whether you own a standard Weber kettle, a large Traeger pellet smoker, or a basic propane grill, there is a dedicated solution that will fire up hot enough for a two-minute pizza. This guide covers the best options to help you pick the right pizza oven for gas grill for your setup and cooking style.
How To Choose The Best Pizza Oven For Gas Grill
The right pizza oven attachment for your gas grill depends on three concrete variables: the grill’s physical shape and cooking grate dimensions, the maximum heat output your burners can sustain, and the style of pizza you want to produce. Skipping any of these checks leads to under-cooked toppings or a scorched stone.
Match the Attachment to Your Grill Type
Gas grills come in two major configurations: standard rectangular grills with a flat cooking surface and round kettle-style grills. A rectangular grill benefits from a fully enclosed box that sits directly on the grates and contains the heat. A kettle grill needs a conversion dome that seals the lid and directs hot air over the stone. Using a flat stone alone on a kettle grill without a dome will never trap enough heat to cook the top of the pizza.
Prioritize Stone Material and Surface Area
Cordierite is the standard for pizza stones because it resists thermal shock up to 2200°F and absorbs moisture from the dough for a dry, crispy bottom. Avoid cheap ceramic or terracotta stones that crack under the direct flame of a gas burner. A stone that is at least 14 inches in diameter gives you room for a 12-inch pizza with a decent crust edge.
Check the Maximum Temperature Rating
Neapolitan pizza cooks best between 700°F and 900°F. If your grill-top accessory includes a built-in thermometer, verify it can register into that range. A simple stone set will not raise the temperature of your grill dome; you need an enclosure that concentrates the burner’s heat. For a standard gas grill, look for a kit that advertises an internal temperature capability of 700°F or higher.

In-Depth Reviews
1. Cuisinart CPO-700 Grill Top Pizza Oven Kit
The Cuisinart CPO-700 is the most straightforward and effective solution for owners of a standard rectangular gas grill. Its stainless steel enclosure sits directly on the cooking grates and creates a contained baking chamber that reaches up to 800°F, which is right in the Neapolitan sweet spot. The included cordierite stone is thick enough to absorb moisture from the dough and deliver a crisp bottom crust in about five to seven minutes.
The built-in thermometer lets you track the internal temperature without opening the lid and flushing out heat. The reflective stainless steel interior directs radiant heat onto the top of the pizza, helping the cheese melt and the toppings char before the bottom burns. The included aluminum peel is lightweight and folds for storage, though several users note it bends under heavier dough.
Assembly requires attaching the thermometer by removing tiny screws, which a few buyers found fiddly, but the overall build quality is typical Cuisinart—solid and reliable. It fits most standard gas grills without modification and stores compactly inside the grill when not in use, making it a low-friction addition to your outdoor cooking setup.
Why it’s great
- Reflective stainless interior conducts heat to the top of the pizza.
- Integrated thermometer eliminates guesswork.
- Fits standard rectangular gas grills without any adapter.
Good to know
- Included aluminum peel feels flimsy under heavy dough.
- Thermometer screw installation is tedious.
- No cover for long-term outdoor storage when off the grill.
2. Pizzacraft PC7001 PizzaQue Deluxe Outdoor Pizza Oven Conversion Kit
The Pizzacraft PizzaQue is purpose-built for Weber-style kettle grills, converting them into a dedicated pizza oven with a stainless steel dome that traps heat and a thermometer that monitors the chamber temperature. It fits both 18-inch and 22.5-inch kettle models, making it one of the most versatile conversion kits for round grills. The included cordierite stone handles the direct heat well, and users report reaching around 900°F with enough charcoal and wood chunks.
The kit includes a charcoal fence that keeps the fuel contained to one side, creating a convection effect similar to a wood-fired oven. The folding aluminum peel is adequate for launching and retrieving pies, though raw dough transfers easier with a separate wooden peel. The door is made of a silicone material that seals the front opening but has been reported to warp or leak air over time, which can make maintaining high temperatures inconsistent.
Assembly is straightforward if you follow the manual closely, but the included instructions offer limited guidance on fuel placement and airflow adjustment. Buyers who replaced the charcoal fence with a vortex or added hardwood chunks found they could hold 800°F+ for multiple pizzas. This kit is an economical entry point to high-heat pizza making if you already own a kettle grill.
Why it’s great
- Converts an existing kettle grill into a high-temperature pizza oven.
- Stainless steel dome retains heat efficiently.
- Cooks a 12-inch pizza in three to five minutes.
Good to know
- Silicone door can warp or fail to seal properly after repeated use.
- Charcoal fence feels flimsy and may need upgrading.
- Raw dough transfer requires a separate wooden peel.
3. CAMPLUX PZ17B 17-Inch Pizza Oven
The CAMPLUX PZ17B is a lightweight, portable grill-top pizza oven that weighs just over 15 pounds and includes a storage bag for easy transport. Its rectangular aluminized steel body sits across the grates of most standard propane and charcoal grills, and the integrated thermometer lets you monitor the internal temperature without lifting the lid. The included 14.8×13-inch cordierite stone provides ample surface area for a full 13-inch pizza.
The smooth aluminized interior is simple to clean after each use, and the removable stone means you can scrub the box without damaging the baking surface. The box design traps heat well enough to cook a pizza in about 8 to 10 minutes on a standard gas grill, and the built-in thermometer helps you avoid the burnt-bottom scenario by showing when the stone has reached the target temp.
The construction uses SPCC cold-rolled steel and aluminized panels that resist rust and warping, though the thin metal panels can dent if handled roughly during transport. The included storage bag is a genuine bonus for campers and RV users who need to pack the oven away when not in use. This oven is best suited for casual pizza nights where portability matters more than achieving an 800°F inferno.
Why it’s great
- Lightweight design with a dedicated storage bag for camping.
- Removable cordierite stone makes cleaning straightforward.
- Built-in thermometer helps monitor chamber temperature accurately.
Good to know
- Thin aluminized panels dent more easily than heavier steel ovens.
- Does not reach the extreme 800°F+ temps of enclosed dome kits.
- Some users report that the stone sits a bit uneven in the tray.
4. Pellethead Pellet Grill Pizza Oven Attachment
The Pellethead attachment is engineered specifically for full-size pellet grills, including Traeger, Pit Boss, Camp Chef, and Rec-Tec models. Instead of laying flat on the grates, it creates a funnel-like chamber that concentrates the hot air from the grill’s fan onto the stone surface, reaching up to 800°F. This design allows a 10-inch pizza to cook in about two to three minutes with a charred crust that rivals a wood-fired oven.
The heavy-duty stainless steel construction holds up well against corrosion, and the adjustable rods at the bottom allow you to secure the attachment to different grill widths without tools. The chamber’s narrow shape limits the pizza size to roughly 10 to 12 inches, but the trade-off is concentrated heat that browns the cheese and leopards the crust evenly. Buyers using Traeger Ironwood 885 models report stone temperatures of 720°F to 750°F when the smoker is set to 450°F.
The main drawbacks are that the stone sits loose inside the chamber and can rattle during handling, and the high heat inside the chamber can cause flame-outs if the pellet grill is set too high without an open lid startup. This attachment is for pellet grill owners who want to add pizza without buying a separate standalone oven.
Why it’s great
- Funnel design concentrates airflow for high-temperature pizza cooking.
- Compatible with most major pellet grill brands.
- No tools required for installation or removal.
Good to know
- Only fits pizza sizes up to 10-12 inches.
- Stone sits loose and can rattle during handling.
- High heat can cause flame-out if the grill lid is closed too soon.
5. Ooni Karu 12 Multi-Fuel Outdoor Pizza Oven
The Ooni Karu 12 is a standalone multi-fuel pizza oven that can run on wood, charcoal, or propane (with the gas burner attachment sold separately). It reaches an extreme 950°F and cooks a 12-inch pizza in about 60 seconds, producing a puffy, charred crust with fully melted toppings. The cordierite stone is positioned in the center of the chamber, and the fuel tray is designed to maximize airflow into the flame for consistent heat delivery.
The build quality is excellent—brushed stainless steel that resists weather, foldable legs for portability, and a removable chimney for compact storage. The oven weighs 26.4 pounds, light enough to take camping or tailgating. The Karu 12 is versatile beyond pizza; the high heat is ideal for searing steaks in a cast iron pan or roasting vegetables with a smoky flavor.
Despite not being a grill-top attachment, the Karu 12 earned its place on this list because it offers gas compatibility through the optional Ooni gas burner, effectively making it a propane-fueled pizza oven that lives outside your grill. The learning curve is steeper than a simple stone set—dough launching technique and heat management require practice—but the results are consistently restaurant-quality.
Why it’s great
- Reaches 950°F for a true Neapolitan cook in 60 seconds.
- Multi-fuel flexibility with optional propane burner attachment.
- Portable, rugged stainless steel construction.
Good to know
- Gas burner attachment is sold separately.
- Steep learning curve for heat management and dough launching.
- 12-inch capacity limits pizza diameter.
6. Ninja Artisan Electric Outdoor Pizza Oven MO201
The Ninja Artisan MO201 is an electric pizza oven designed for dedicated outdoor use without requiring a gas or charcoal grill at all. It reaches 700°F and cooks a 12-inch pizza in about three minutes, with five preset cooking modes for Neapolitan, Thin Crust, Pan, New York, and Custom styles. The electric heating element eliminates the need to manage a live flame, making it a plug-and-play option for consistent results.
The oven includes a 12×12-inch pizza stone, a baking pan, and a proofing function that holds the dough at 90°F for optimal rise. The Chef’s View Window on the door lets you monitor the pizza’s progress without losing heat. The weather-resistant exterior is built to be stored outdoors with an optional cover, which is rare for electric appliances.
Because it’s electric, this oven cannot match the extreme 900°F+ of a gas or wood-fired unit, so you will not get the same rapid charring. However, the temperature control is far more precise than a gas grill conversion, and the 5-in-1 functionality allows you to bake, broil, proof, and warm dishes alongside the main pizza cook. For beginners or those who want a simple outdoor pizza solution, this is a compelling entry point.
Why it’s great
- Electric heat provides consistent temperature without flame management.
- Five pizza presets and proofing function add versatility.
- Weather-resistant build allows outdoor storage.
Good to know
- Max temp of 700°F cannot replicate the rapid char of 900°F ovens.
- Requires access to an outdoor power outlet.
- Baking pan and stone measure 12×12 inches, limiting pan pizza size.
7. Onlyfire 4-Piece Pizza Stone Set
The Onlyfire 4-Piece Pizza Stone Set is a budget-friendly kit that provides the essential tools for pizza making on a grill: a 15-inch round cordierite stone, a 14×16-inch aluminum peel with a wooden handle, a stainless steel spatula, and a pizza cutter. The stone is rated up to 2200°F, which means it will not crack under the direct heat of a gas burner the way cheaper ceramic stones often do. For grill owners who already have an enclosed dome, this kit is a complete solution for launching and turning pizzas.
The cordierite stone’s porous surface wicks moisture away from the dough, giving you a crispy bottom crust even when cooking on a standard grill grate. The peel is large enough to handle a 14-inch pizza comfortably, and the long handle keeps your hands away from the heat. The stainless steel spatula is a nice bonus for flipping other grilled foods like burgers or pancakes.
The downsides are that this kit does not include any enclosure or dome to trap heat—you are relying on your grill’s existing lid to create a baking environment. This means you won’t get the high top-heat needed for proper cheese charring. Additionally, the included pizza cutter is cheap and prefers a one-piece design for durability. This set is best for grillers who already have a covered gas grill and want to add pizza capability without buying a full oven attachment.
Why it’s great
- 2200°F-rated cordierite stone resists thermal shock under direct flame.
- Complete four-tool kit at an entry-level price point.
- Large 15-inch stone accommodates 14-inch pizzas easily.
Good to know
- No enclosure to concentrate top heat for cheese melting.
- Pizza cutter feels cheap and lacks a solid one-piece design.
- Wooden peel handle lacks a lifting edge for easy slide-under.
