An outdoor pizza oven turns a weeknight from frozen pizza or delivery into a 90-second restaurant-quality pie at home. The category has grown fast since 2020, with Ooni, Gozney, Solo Stove, and several others producing home ovens that genuinely hit 850 F or higher. The choice between wood-fired and gas is not a small one. It changes how you cook, how often you cook, what pizza styles work best, and how much your patio smells like a wood fire. This guide walks through the engineering, the practical trade-offs, and how to match the oven type to how you actually plan to use it.
Why pizza needs high heat
Pizza dough cooks fastest at very high temperatures because the outside hits the Maillard reaction and the inside steams almost simultaneously. At 500 F (a standard home oven), a pizza cooks in 8 to 12 minutes and the dough loses moisture during that time, ending up dense or crackery. At 800 F, the same pizza cooks in 90 to 120 seconds, the crust puffs from rapid steam release, and the interior stays open and tender.
The temperature ceiling on a home oven is a hard physical limit. Even with the broiler on and a baking steel preheated for an hour, a domestic oven tops out around 600 F at the stone. That is why pizza enthusiasts move to dedicated outdoor ovens.
Wood-fired ovens hit 850 to 1000 F. Gas ovens hit 700 to 850 F. The difference matters most for Neapolitan and Roman styles, less for New York and pan styles.
How wood-fired pizza ovens work
A wood-fired pizza oven burns small split hardwood (oak, maple, beech, or kiln-dried mixed hardwood) in a chamber that also contains the cooking stone. The fire is built off to one side of the dome, the flames roll up and across the ceiling, and the radiant heat from the stone, the dome, and the live flame all cook the pizza simultaneously.
The cooking proceeds in three heat phases:
Initial fire (20 to 30 minutes): full burn to bring the stone to 700 to 900 F.
Cooking phase (30 to 90 minutes): smaller maintained fire on one side, the stone stable, pizzas going in one at a time.
Cooldown (1 to 2 hours): residual heat does well for breads, roasted vegetables, and slow-cooked dishes after pizza is done.
The required wood is small, often called “pizza splits,” about 12 to 15 cm long. A 4-kilo bundle from a hardware store runs 8 to 12 dollars and gets you a full pizza session.
How gas pizza ovens work
A gas oven uses one or two propane or natural gas burners positioned behind or under the stone. The flame heats the stone and the dome via convection and radiation. Most consumer gas ovens (Ooni Koda 16, Gozney Roccbox, Solo Stove Pi) light from cold to 850 F in 15 to 20 minutes and hold that temperature indefinitely with a steady knob setting.
The cooking is more like an oven than a campfire. Heat is consistent. The flame is the same minute after minute. The variables that matter become dough handling, sauce quantity, and turning speed, not fire management.
The Neapolitan question
Authentic Neapolitan pizza, the kind made in Naples and certified by the AVPN (Associazione Verace Pizza Napoletana), requires a wood fire and 800 to 900 F. The certification is strict. Gas ovens cannot make AVPN-certified Neapolitan pizza, no matter how high they get.
For the home cook, the AVPN distinction matters less than the flavor distinction. Wood smoke contributes a subtle char and aroma to the crust that gas does not replicate. Side-by-side blind tastings show that experienced eaters can identify wood-fired pizza 70 to 80 percent of the time. The flavor is real, but not enormous.
If Neapolitan style is the goal, wood-fired is the answer. If you make a mix of styles (New York, Detroit, pan), the flavor advantage of wood is smaller.
The convenience gap
Gas wins on convenience by a wide margin. Twenty minutes from “I want pizza” to “the first pie is going in.” No wood to store, no fire to manage, no ash to clean.
Wood-fired ovens take longer to fire (30 minutes minimum), need an active fire-tender during cooking (or a tongs poke every 5 minutes), require wood storage (a covered space for at least a week’s supply), and produce ash that needs to be emptied between sessions.
For a weeknight pizza after work, gas is the realistic option. For a weekend pizza party where the fire is part of the experience, wood-fired is the better choice.
Smoke and neighbor considerations
Wood-fired ovens produce visible smoke during the start-up phase (10 to 20 minutes), then almost none once the fire reaches operating temperature. The smoke profile is similar to a small fire pit.
In dense suburban neighborhoods, the start-up smoke can drift to neighbor yards. In townhouses or condos with shared patio space, wood-fired ovens are often prohibited by HOA or fire-code rules. Check before buying.
Gas ovens produce essentially no visible smoke, just radiated heat. They are legal in nearly all residential settings.
Cost comparison
Entry-level gas: Ooni Koda 12 at around 350 dollars, Solo Stove Pi at 400 dollars.
Mid-range gas: Ooni Koda 16 at 600 dollars, Gozney Roccbox at 500 dollars.
Premium gas: Gozney Dome S1 at 1500 dollars.
Entry-level wood: Ooni Fyra 12 (pellet) at 350 dollars, Solo Stove Pi Fire at 400 dollars.
Mid-range wood: Ooni Karu 16 (multi-fuel) at 800 dollars, Gozney Dome (multi-fuel) at 1800 dollars.
Premium wood: Forno Bravo Pizzeria 90 or custom-built brick oven, 3000 to 10000 dollars.
Multi-fuel ovens (Karu, Dome) accept both wood and gas via a swappable burner attachment. They cost more upfront but eliminate the choice entirely.
Who should buy each type
Buy gas if you want pizza on a weeknight, you live in dense housing, your patio space is small, you are new to high-heat outdoor cooking, or you make a mix of pizza styles other than Neapolitan.
Buy wood if you want the full ritual of fire and pizza, you have space for wood storage, you make pizza primarily on weekends with friends, Neapolitan style is the goal, and you enjoy the cooking process as much as the eating.
Buy multi-fuel if you cannot decide. The Ooni Karu 16 and Gozney Dome cover both modes and are the most flexible options at the higher end of the budget.
The pizza oven is the rare patio appliance where the entry-level products genuinely make professional-grade pizza in your backyard. Pick the fuel that fits your life, get a thermometer for the stone, and plan to be making better pizza than your local delivery within 5 cooks.
Frequently asked questions
How hot does a wood-fired pizza oven actually get?+
A well-fired Ooni Karu 16 or Gozney Dome on hardwood hits 850 to 950 F at the stone after 25 minutes of heating. The dome air temperature can reach 1000 F. That is the temperature range where Neapolitan pizza cooks in 60 to 90 seconds. Gas pizza ovens like the Ooni Koda 16 or Gozney Roccbox max out at 750 to 850 F, which is plenty for most pizza styles but a step below true wood-fire performance.
Can you cook anything other than pizza in a pizza oven?+
Yes. The high-heat environment is excellent for searing steaks, roasting whole chickens, baking bread with a strong crust, charring vegetables, and finishing seafood. The Gozney Dome and Ooni Karu 16 both have accessories for cast-iron pan cooking. Treat the pizza oven as a high-temp outdoor convection oven that also does pizza, not a single-purpose tool.
How long does it take to learn to use a wood-fired oven?+
The fire management learning curve is real. Most new owners burn the first 3 to 5 pizzas figuring out flame position, dough launch, and turning rhythm. By pizza 20, most home cooks make a respectable Neapolitan. By pizza 50, the process becomes second nature. Gas ovens shortcut the learning curve because the temperature is consistent and the only variables are dough handling and timing.
What is the fuel cost difference?+
A small bundle of kiln-dried hardwood for a wood-fired session costs 8 to 12 dollars and lasts 6 to 10 pizzas. That works out to about 1 to 2 dollars per pizza in fuel. A 20-pound propane tank costs 20 to 30 dollars to refill and lasts roughly 40 to 60 pizzas on a Roccbox or Koda, working out to 0.40 to 0.75 dollars per pizza. Gas is cheaper per pizza if you cook frequently.
Are pellet pizza ovens worth considering?+
Pellet ovens like the Ooni Fyra 12 hit the wood-fired flavor at a budget price but require near-constant pellet feeding to stay above 800 F. The result is pizza that tastes between gas and full wood. If you want the wood flavor without splitting logs, pellets are a reasonable middle ground. If you want truly hands-off operation, gas is better. If you want the full ritual, real wood is the answer.
