8 Best Ooni Gas Pizza Ovens (November 2026)
The best Ooni gas pizza ovens include the Uniflasy Gas Burner for Pizza Oven Accessories for Karu 12 fuel conversion, the BIG HORN 12" Outdoor Pizza Oven for multi-fuel outdoor cooking, and the Ooni Karu 12 & Karu 2 Gas for official Karu gas control.
On this page (5 sections)
The best Ooni pizza oven gas option for Karu owners is the Ooni Karu 12 & Karu 2 Gas Burner, while the Ooni Koda 2 is the simplest complete propane oven.
That split depends on what you already own. A burner upgrades a suitable Karu, while a complete oven gives you everything in one package.
Choose by oven compatibility, pizza size and preferred fuel. A burner cannot cook pizza without the oven it attaches to.
A complete gas oven brings the stone, hose and regulator together as a matched set. That simplifies setup and care, though it costs more in one purchase.
We compared stated burner fit, cooking size, fuel setup, heat controls and included parts. A small mismatch in fit or size can matter more than a headline temperature claim.
For Karu owners, the key question is whether gas fits your current routine. If you use wood or charcoal for flavour and want gas for quicker weekday cooking, an attachment adds flexibility.
If you do not own a compatible model, a complete oven is usually safer. You can place it, connect propane and focus on the stone and heat controls.
If you already own a Karu, read the Ooni Koda 2 Pro review only if you are also considering a complete gas oven. That helps if you prefer fixed propane cooking with a larger area.
For a wider cooking area, compare the Ooni Koda 16 dimensions before choosing a surface. The full body, hose routing and working space also need room.
Size should match home cooking. A 12 in format suits one pizza at a time, while 14 in and larger formats give more room to launch and turn pizza.
Fuel control is the other daily difference. Gas lets you adjust heat during the cook, while wood and charcoal need more attention to feeding and airflow.

Which Ooni pizza oven gas model is best for your setup?
The best choice depends first on compatibility, then on cooking size. A burner is a strong value when you already own a matching Karu, while the Koda models are simpler when you need a complete propane oven.
Uniflasy Gas Burner for Pizza Oven Accessories: Best for Karu 12 fuel conversion
- Fits Karu 12 and Karu 12G
- Propane connection valve hose
- Reaches 950°F in 25 minutes
- Requires oven door off and chimney on
This burner adds propane cooking to compatible Karu 12 and Karu 12G ovens. It suits buyers who already own a compatible oven and want adjustable gas heat.
Pros
- Fast gas conversion
- Adjustable heat during cooking
- Propane hose and screws included
Cons
- Not a complete pizza oven
- Compatibility must be checked carefully
- Door must be removed during use
The Uniflasy burner is the top pick for a compatible Karu 12 or Karu 12G owner who wants propane heat without replacing the oven. It also lists compatibility with the Fyra 12 when used with a propane conversion kit and with the BigHorn Outdoors 12 in oven.
The package includes 1 gas burner, 1 propane connection valve hose and 2 screws. Installation uses the screws to attach the burner, but the oven door must be off and the chimney must stay on during use.
Uniflasy states that the burner can reach 950°F in 25 minutes. Its adjustable heat makes it easier to change the cooking temperature while you turn pizza, which may help keep the crust cooking evenly as toppings finish.
The burner suits quick pizza and other foods such as seared vegetables. Follow the ignition sequence carefully by opening the propane flow slowly, turning the control slowly and holding the knob after ignition.
Choose this when you already have a compatible oven and want a gas option. Check the exact oven model before ordering because this is an attachment, not a complete pizza oven.
BIG HORN 12" Outdoor Pizza Oven: Best for multi-fuel outdoor cooking
- 12 in pizza capacity
- Pellet, gas and electric options
- Reaches 1110°F
- Folding legs and stainless steel body
This compact stainless steel oven starts with wood pellets and can use separate gas or electric attachments. It fits buyers who want fuel choice in a portable 12 in format.
Pros
- Three fuel options
- 18 to 20 minute preheat claim
- Lightweight 25 lb design
Cons
- Gas attachment sold separately
- Electric attachment sold separately
- Pellets need dry storage
The BIG HORN 12 in oven is the best multi-fuel choice here because it starts with wood pellets and can also use separate gas or electric burner attachments. That gives you more fuel choices than a gas-only oven, but the extra attachments are not included.
Its stainless steel body has folding legs and weighs 25 lb. The 12 x 12 in pizza stone fits pizzas in the 12 in class, while the 21.6 x 14 x 28 in overall size matters when you plan storage or transport.
BIG HORN states that the oven can reach 1110°F and preheat in 18 to 20 minutes. Its cooking guidance calls for turning pizza often, especially when making Neapolitan-style pies with a small amount of sauce and toppings.
Pellet cooking requires natural hardwood pellets stored in an airtight container. Moisture can affect how pellets burn, so fuel storage becomes part of the routine.
Pick this oven if you want to move between pellets, gas and electric cooking. Choose a dedicated Ooni gas model if you want the simplest fuel setup.
Ooni Karu 12 & Karu 2 Gas: Best for official Karu gas control
- Fits Karu 2, 12G and Karu 12
- 28mbar propane burner
- Gas regulator and hose included
- Low-power cooking function
This Ooni burner is the clearest choice for compatible Karu owners who want a direct gas attachment. Its heat dial and low-power function give you more control than a fixed fuel setup.
Pros
- Official Karu compatibility
- Regulator and hose included
- Up to 950°F cooking range
Cons
- Only fits specified Karu ovens
- Does not include an oven
- Propane connection required
The Ooni Karu 12 & Karu 2 Gas Burner is the best official-style gas attachment for owners of the compatible Karu models. It fits Karu 2, 12G and Karu 12 ovens and includes a 28mbar propane regulator and hose.
The burner attaches to the back of the oven and adds a heat-control dial. Ooni states that it reaches temperatures up to 950°F and includes a low-power cooking function for lower-temperature pizza or meat dishes.
Its stainless steel body measures 7 x 4 x 9.5 in and weighs 2.1 lb. Gas cooking can also mean less soot and cleanup than cooking with wood or charcoal.
This burner is a better match for a Karu owner than for someone starting from zero. You still need the compatible oven and a propane supply, so compare the combined setup with a complete Koda 2.
For more size planning, read what are the Ooni Koda 12 dimensions? and compare that compact format with the Karu range.
BIG HORN Gas Pizza Oven: Best for 15 in family pizzas
- 15 in cooking capacity
- 23,000 BTU dual burners
- Reaches 1070°F
- Pizza stone, peels and regulator hose included
The BIG HORN gives you a larger cooking area than 12 in ovens and includes a pizza stone, foldable peel, stainless steel peel and propane regulator hose. It suits family meals and outdoor gatherings.
Pros
- Large cooking area
- Dual independent controls
- Built-in thermometer
Cons
- Heavier 35.3 lb body
- Larger footprint
- Product data differs on stone size
The BIG HORN Gas Pizza Oven is the best larger-format non-Ooni pick for family cooking. Its cooking area fits up to a 14.7 in pizza, and the 15 in class gives you more working room than a 12 in oven.
The dual side burners are rated at 23,000 BTU, and BIG HORN states that the oven reaches 750°F in 10 minutes and up to 1070°F at maximum. Its arc-shaped chamber is designed for even heat circulation, with no rotation claim for pizza cooking.
The stainless steel oven measures 21 x 18.6 x 23 in and weighs 35.3 lb. A built-in thermometer, two control knobs, anti-skid feet and a removable door support a more structured outdoor setup.
The package includes a foldable pizza peel, a pizza stone and a propane regulator hose. The product information uses different stone measurements in different places, so confirm the exact stone size if that detail affects your plan.
Choose this for a wider family pizza format and bundled cooking parts. For an Ooni comparison, see Gozney Roccbox vs Ooni Koda 16.
Ooni Karu 2 Pro Multi-Fuel Pizza Oven: Best for large multi-fuel cooking
- 16 in pizza maker
- Wood and gas fuel options
- Reaches 950°F in 15 minutes
- Integrated thermometer and glass door
The Karu 2 Pro is for buyers who want wood or charcoal cooking out of the box and gas as an added option. Its large format and integrated thermometer suit more involved outdoor cooking.
Pros
- 16 in cooking format
- Wood and gas flexibility
- ViewFlame glass door
Cons
- Gas burner sold separately
- Heavier than compact ovens
- More setup choices to manage
The Ooni Karu 2 Pro is the best choice when you want a large multi-fuel oven and gas as an optional fuel. Wood or charcoal cooking is available out of the box, while the Ooni Karu 2 Pro Gas Burner is sold separately.
Ooni states that the oven reaches 950°F in 15 minutes and cooks pizza in 60 seconds. The fully insulated body, integrated digital thermometer and ViewFlame glass door give you more information while you cook.
The Karu 2 Pro is a 16 in outdoor pizza maker with a stainless steel body and a 15.3 kg weight. That size is useful for large pizza, but it also requires more counter space and a stronger storage plan than compact models.
The glass door helps you watch the food while retaining heat through the insulated oven body. Ooni also lists Ooni Connect app support for smart cooking functionality.
Pick this when wood and gas flexibility matters more than a simple propane-only setup. Read the Ooni Koda 2 Max cooking guide if you are comparing it with an even larger gas cooking format.
Ooni Koda 2 Propane Gas Pizza Oven: Best for simple 14 in propane cooking
- 14 in cooking area
- 28mbar regulator and hose included
- 375°F to 950°F range
- 35 lb portable body
The Koda 2 is a complete propane oven for buyers who want a wider cooking area without adding a separate burner. Its tapered flame system and thicker stone are aimed at repeat cooking.
Pros
- Complete propane setup
- 14 in pizza stone
- Portable 35 lb design
Cons
- Not compatible with natural gas
- Propane only
- Smaller than the Koda 2 Pro
The Ooni Koda 2 is the best complete 14 in propane oven for buyers who want a straightforward gas setup. It includes the oven, pizza stone, gas hose and 28mbar regulator.
This model is propane only and does not connect to natural gas. Its 14 in cooking area gives you more room than a 12 in oven, while the 35 lb body remains portable for outdoor cooking.
Ooni lists a temperature range from 375°F to 950°F. Its G2 Gas Technology uses a tapered flame gas burner system, and the thicker pizza stone is designed to retain heat between back-to-back cooks.
The oven measures 21.5 x 13.1 x 28.4 in. Check the Ooni Koda 2 Pro dimensions if you need a larger cooking area or are planning a permanent outdoor counter.
Choose Koda 2 for a complete propane setup without buying a separate burner. Compare other countertop gas pizza ovens if you want a complete gas oven.
It is a better starting point than a Karu gas attachment if you do not already own a compatible multi-fuel oven.
Ooni Koda 2 Pro Gas Pizza Oven: Best for large propane cooking
- 18 in cooking area
- 160°C to 500°C range
- Ooni Connect temperature hub
- Propane hose and regulator included
The Koda 2 Pro is the strongest fit for large pizzas, cast iron or sheet pans when you have room for a wider oven. Its digital temperature hub adds information for buyers who want connected cooking.
Pros
- 18 in cooking area
- Wide temperature range
- Pyrolytic cleaning feature
Cons
- Large footprint
- Not compatible with natural gas
- Heavier 27.38 kg body
The Ooni Koda 2 Pro is the best large Ooni gas oven for buyers who need an 18 in cooking area. It is built for propane and includes the pizza oven, stone, hose and regulator.
Its cooking area gives you space for large pizza, cast iron or sheet pans. The stated temperature range is 160°C to 500°C, and Ooni lists a tapered flame propane system designed to reduce hot and cold spots.
The Koda 2 Pro also includes the Ooni Connect Digital Temperature Hub. It sends ambient temperature and food probe readings to a smartphone, which suits cooks who want more information during longer recipes.
The oven measures 25.6 x 26.8 x 15.5 in and weighs 27.38 kg. Its larger footprint is the main trade-off, so compare it with the Ooni Koda 2 Max setup before choosing a counter.
Pick the Koda 2 Pro for large pizzas and broader outdoor cooking. Pick the Koda 2 when the 14 in size is enough and portability matters more.
Commercial Chef Outdoor Gas Pizza Oven: Best for an included accessory bundle
- 12 in pizza cooking
- Dual L-shaped burners
- Reaches 932°F in 15 minutes
- Door, peel, cutter and cover included
This compact gas oven is useful when you want several starter accessories in one package. The baffle door helps retain heat, but preheating with it should be limited to 15 minutes.
Pros
- Accessory bundle included
- L-shaped burners
- Flame safety device
Cons
- 12 in pizza size
- Baffle door use has time limits
- Lower score for a less established fit with Ooni ovens
The Commercial Chef Outdoor Gas Pizza Oven is the best bundle for buyers who want several basic accessories included. The package includes a pizza oven door, water-resistant carry cover, foldable perforated peel and stainless steel pizza cutter wheel.
Its dual L-shaped burners are designed for 12 in pizza cooking, and Commercial Chef states that the oven reaches 932°F in 15 minutes. The die-cast aluminum body measures 25.1 x 16.1 x 12.4 in and weighs 10 kg.
The baffle door helps retain heat during colder use and between pizzas. Limit preheating with the door to 15 minutes, and limit warming between pizzas to 5 minutes to avoid harming the knob base.
A built-in flame safety device cuts the gas supply if the flame goes out. The oven also uses one-touch ignition and a built-in dial for heat adjustment.
Choose this if the included door, cover, peel and cutter reduce the number of separate items you need. Choose an Ooni model if exact Ooni compatibility is the main goal.
How should you choose an Ooni gas pizza oven size?
Choose 12 in for compact cooking, 14 in for more room to launch and turn pizza, and 16 to 18 in for large pizzas or pan cooking. A larger stone can make handling easier, but the oven also needs more counter space and storage room.
Measure the full oven footprint, not only the stone. Include room for the propane connection, tools, airflow and safe movement around a hot oven.
A 12 in oven can work well for one pizza at a time and smaller outdoor spaces. The 14 in Ooni Koda 2 gives you more room without the footprint of the 18 in Koda 2 Pro.
For large cooking, compare the Ooni Koda 2 Max cooking guide with your expected pizza size and serving pattern. If you already own a Koda 16, the guide to cooking with an Ooni Koda 16 covers the larger workflow.
Is an Ooni gas burner better than a complete gas oven?
An Ooni gas burner is better when you already own a compatible Karu and want to add propane cooking. The burner gives your existing oven a second way to cook without replacing the whole setup.
A complete Koda oven is simpler when you need the oven, stone, hose and regulator in one setup. Setup is mostly placement, connecting propane and preheating the stone before the first pizza.
The burner route suits owners who value flexibility. You can keep wood or charcoal for some cooks and use gas when you want steadier control and a cleaner routine.
The complete oven route suits buyers who want fewer moving parts. There is no need to match a burner to a Karu model, and the cooking area is sized for the fuel system.
Check the compatibility line before buying any attachment. The official Karu burner fits Karu 2, 12G and Karu 12, while the Uniflasy burner has its own list and installation requirements.
A close name is not enough, so confirm the exact model printed for your oven. Compatibility affects fit, heat and safe operation.
That check also matters for safety. The burner must sit correctly at the back of the oven, the hose must reach the propane supply without strain, and the door and chimney arrangement must match the attachment instructions.
Gas gives a more direct heat-control routine than wood or charcoal. You can turn heat down when the top browns too fast or raise it when the stone needs to recover after a cold pizza goes in.
That control changes how you manage a cook. You spend less time feeding fuel and more time watching the base, turning pizza and adjusting the finish.
Multi-fuel ovens offer more cooking choices, but they require managing fuel changes and extra accessories. Wood, charcoal, pellets, gas and electric attachments each bring storage, cleaning and preheat habits.
A complete gas oven still needs propane storage and outdoor placement, but the routine stays consistent.
The trade off is cost of entry against long term flexibility. A burner suits a matching Karu, while a complete oven is cleaner for a first purchase.
What should you check before using a gas pizza oven?
Place the oven outdoors on a stable surface with enough clearance above and around it. The surface should support the oven, stone and any pan without wobbling when you slide a peel in or out.
Keep the propane connection secure and follow the burner ignition instructions. Let the oven cool fully before moving or cleaning it.
Check the hose route before cooking so it stays clear of heat, foot traffic and sharp edges. Plan the working area before you light anything.
You need room for the peel, a landing board for the finished pizza and a safe place for tools while the oven is hot. Reaching across a hot chamber is never a good idea.
Gas burners become extremely hot, even when the body is portable. Portability helps storage and transport, but the stone and metal parts hold heat long after the flame is off.
Commercial Chef guidance warns against touching the oven before it cools. Its baffle door also has time limits during preheating to protect the knob base.
Treat door use as a short heat retention step rather than a long preheat method. Limit preheating with the door to 15 minutes, and warming between pizzas to 5 minutes.
Keep pizza toppings light when cooking at very high heat. Heavy wet toppings can cool the centre, slow the bake and leave a soft base.
Turn smaller pizzas as needed, watch the crust closely and reduce heat when the top cooks faster than the base. Small turns spread heat more evenly and move pizza away from a hot side.
Learn your oven in stages. Start with a simple margherita style bake, then add toppings once you know how fast the base sets at each setting.
Clean stones according to the oven instructions. Avoid soap or water unless the manufacturer allows it, and scrape off baked-on food once the stone has cooled.
After cooking, brush out loose debris and check the hose and fittings while the oven is off. Store pellets, covers and accessories where they stay dry and away from direct heat.
Check the flame and controls before each session. If ignition is slow, the flame looks wrong or a connection feels loose, stop and follow the maker guidance.
Which best Ooni pizza oven gas pick should you buy?
Choose the Uniflasy burner if you own a compatible Karu 12 or Karu 12G and want the highest-scoring gas conversion. It is an attachment rather than a complete oven, so the first test is whether your exact Karu model matches the stated fit.
Choose the Ooni Karu 12 & Karu 2 Gas Burner if official Karu compatibility and a low-power function matter most. The included regulator and hose make the propane set up clearer, and the heat dial suits cooks who want to change temperature during a bake.
Choose the Ooni Koda 2 for a complete 14 in propane oven, or the Koda 2 Pro for an 18 in cooking area and connected temperature readings. The Koda 2 gives more room than a 12 in oven without moving to the larger Pro footprint.
Pick the BIG HORN 12 in if you want pellet, gas and electric options, with the extra attachments bought separately. That route suits cooks who like changing fuel for the meal in hand, but it asks for more storage and more decisions before each cook.
If large family pizzas are your priority, the BIG HORN Gas Pizza Oven and Karu 2 Pro offer more cooking room than compact models. A larger area can make launching and turning easier, yet it also needs a bigger table, more storage space and a clearer path for the peel.
Think about who the oven suits in daily use. A compact 12 in oven fits a small patio and one pizza at a time, while 14 in to 18 in models suit groups, larger pies and extra dishes such as pans or vegetables cooked alongside pizza.
Set up and care should shape the final call. Gas only models keep the routine simple, multi-fuel models add choice, and accessory bundles can reduce extra purchases, but every option still needs outdoor placement, safe clearances and cooling time before cleaning.
The trade off is simple to state. Attachments reward existing Karu owners, complete ovens reward first time buyers, and larger ovens reward family cooking at the cost of space and weight.
Start with the model's fuel, size and placement requirements, then confirm that your outdoor surface can support the full setup. Once those basics are settled, the best pick is the one that matches your oven, your pizza size and the way you prefer to cook.

Frequently asked questions
What is the best Ooni pizza oven gas option?
The best Ooni pizza oven gas option depends on your oven and pizza size. The Ooni Karu 12 & Karu 2 Gas Burner suits compatible Karu owners, while the Koda 2 is a complete propane oven with a 14 in cooking area.
Choose the Koda 2 Pro for an 18 in format.
Is the Ooni Koda 2 propane only?
Yes. The Ooni Koda 2 connects to a propane gas bottle with the included 28mbar regulator and hose.
It is not compatible with natural gas, so check your fuel setup before buying and keep the oven outdoors in a suitable cooking area.
Can you add gas to an Ooni Karu pizza oven?
Yes, but the burner must match the Karu model. The Ooni Karu 12 & Karu 2 Gas Burner fits Karu 2, 12G and Karu 12 ovens, while the Uniflasy burner is listed for Karu 12 and Karu 12G compatibility.
Check the exact model first.
What size Ooni gas pizza oven should you choose?
Choose a 12 in oven for compact cooking and a 14 in model for more room to turn and launch pizza. An 18 in oven suits large pizzas, cast iron or sheet pans, but it needs more counter space.
Compare the Ooni Koda 2 dimensions before planning placement.
Is gas easier than wood for pizza ovens?
Gas usually gives simpler heat control and less soot than wood or charcoal. Wood can add a different cooking routine and flavor, while multi-fuel ovens let you switch between methods.
Gas still needs safe outdoor placement, a compatible hose and careful burner operation.
