Gas is far more controllable and gets used more often. Wood gives the flavor and the ritual, and more failed pizzas in the first month. Gas reaches roughly 900°F in 15 to 20 minutes on a single knob and holds it steady; wood takes 25 to 45 minutes, needs small pieces of kiln-dried hardwood fed every few minutes, drifts in temperature while you cook, and leaves ash and soot behind. Both make excellent pizza. The question is which failure mode you would rather live with — and if you are unsure, a multi-fuel oven with both burners is the honest answer.
How do they compare, concretely?
| Gas | Wood | |
|---|---|---|
| Preheat to ~900°F | 15–20 min | 25–45 min |
| Temperature control | A knob; holds steady | Fuel management; drifts constantly |
| Attention while cooking | Just the pizza | Pizza and the fire |
| Flavor | Clean, no smoke note | Subtle smoke, more irregular char |
| Cleanup | Brush the stone | Brush the stone, shovel ash, window soot |
| Fuel per session | ~$1.50–3 of propane | ~$2–6 of kiln-dried hardwood |
| Fuel storage | A 20 lb tank outdoors | Dry storage for split hardwood |
| Learning curve (the oven) | Essentially none | Real — fire management is a skill |
| Sessions per year, typical | Higher | Lower |
| Cold or windy weather | Works, uses more fuel | Harder to establish and hold |
The row that decides most purchases is the second-to-last one. Neither fuel makes a better pizza in any absolute sense — both comfortably reach the 750 to 900°F range where Neapolitan pizza works. What differs is friction, and friction determines how many pizzas you actually make.
Why does fuel choice predict whether the oven gets used?
Think through a weeknight. It is 6pm, you have dough in the fridge, and you are deciding whether tonight is pizza night.
With gas: walk out, turn the knob, come back in twenty minutes. The stone is at 900°F, it stays there while you cook, and when you are done you brush the stone and cover the oven. Total commitment beyond eating: maybe ten minutes of attention.
With wood: fetch wood from storage, build a fire, wait ten to fifteen minutes for it to establish, push the coals across, feed it up while checking the stone, cook while continuing to feed it, then wait for it to cool and shovel the ash out tomorrow. Total commitment: an hour and a half of involvement, most of it enjoyable but all of it active.
On a Saturday with friends coming over, the wood version is better in every way — it is part of the evening rather than an obstacle to it. On a Tuesday in October, the gas version is the only one that happens. That asymmetry is why owner reviews of wood-only ovens contain so many variations of "we loved it the first summer and then it sat".
Does wood really taste better?
A little, and mostly for a reason people misattribute.
A Neapolitan pizza is in the oven for 60 to 90 seconds. That is not long enough to absorb much smoke — compare it with brisket sitting in a smoker for twelve hours. The wood note in a properly made pizza is genuinely subtle: identifiable side by side against a gas pizza, easy to miss on its own.
What wood does change noticeably is how the flame behaves. A live fire produces rolling flame that licks across the dome and over the top of the pizza, and that produces more irregular, more attractive blistering on the rim than the steadier heat of a burner. Much of what gets described as wood flavor is actually that char pattern — and a good gas oven with the flame pushed high gets closer to it than people expect.
One thing worth saying plainly: bad wood tastes worse than gas. Wood above about twenty percent moisture smokes acridly, soots the stone and the window, and puts a genuinely unpleasant note into the crust. A wood oven fed with damp yard wood makes worse pizza than any gas oven. Kiln-dried hardwood in small pieces is not optional if flavor is your reason for choosing wood.
What wood firing actually asks of you
- The right fuel, stored dry. Kiln-dried hardwood — oak, maple, beech, ash, fruitwood — split to roughly finger-to-wrist thickness. Never softwood, which resins and sparks. Never treated, painted or engineered lumber, pallets or driftwood, all of which release genuinely toxic compounds, and this is food.
- A fire-building routine. Small fire in the center, establish, push the coals to one side or the back, feed up to temperature.
- Reading the stone rather than the dome. An infrared thermometer aimed at the floor is the most useful accessory in wood firing. The dome runs hot long before the stone does, and launching on the dome reading is the classic cause of a burnt top and a pale, floppy base.
- Feeding while cooking. Little and often. A big log drops the temperature while it catches and then surges past where you want it.
- Working with a hot side. The coals sit to one side, so one edge of the pizza cooks faster. Turn every 20 to 30 seconds, toward the fire, so each quarter gets equal exposure.
- Ash management. Cold ash into a lidded metal container, outdoors. Wet ash left in the chamber is mildly caustic and corrodes steel from the inside, which shortens the oven's life more than anything else you can do to it.

And what gas gives up
To be fair to wood, gas is not free of compromises.
- No smoke note at all. If the wood flavor is genuinely the reason you want an oven, gas will not deliver it and you will know.
- Less dramatic char. A burner produces steadier, more even heat, which is good for consistency and slightly less good for the irregular leopard spotting people photograph.
- Tank management. Running out of propane mid-session is a specific and annoying failure that wood does not have. Keep a spare tank, and see our guide on telling whether a propane tank is empty.
- Less of an occasion. Turning a knob is efficient rather than atmospheric. For some people that is exactly what is lost.
Multi-fuel: the honest recommendation
For most buyers, a multi-fuel oven is the right answer — and the reason is not that it is a compromise, it is that it lets each fuel do what it is good at. Wood on a Saturday evening with people around. Gas on a Wednesday when you want dinner. Owners who have both burners use their oven noticeably more than wood-only owners do, and they also make better wood-fired pizza, because they are not forcing a wood session on a night when they do not have the patience for it.
The trap is straightforward: on most multi-fuel ovens the second burner is sold separately, and a large number of buyers get the oven and never get around to the burner. Budget for both up front. The Ooni Karu range ships wood-capable and takes a gas burner; the Gozney Roccbox ships with the gas burner and takes a wood one. Either sequence works — just complete it.
One thing that does not work: converting a dedicated gas oven to wood. Ovens like the Ooni Koda have no chimney, no ash access and no provision for a solid-fuel bed, and improvising one is genuinely dangerous. If you might want wood eventually, buy multi-fuel now.
Which should you buy?
| If this is you | Buy | Why |
|---|---|---|
| You want pizza on a weeknight | Gas | Twenty minutes and a knob, no cleanup beyond the stone |
| You love process and cooking over fire | Wood or multi-fuel | The tending is the point, not the obstacle |
| You entertain and want the theater | Multi-fuel | Wood for guests, gas for the family |
| You are learning to make pizza | Gas | One variable to master instead of two |
| You live somewhere cold or windy | Gas | Wood is much harder to establish and hold in wind |
| Local rules restrict open burning | Gas | Some jurisdictions and HOAs limit wood-burning appliances |
| You have limited storage | Gas | A tank outdoors beats a stack of dry hardwood |
| Smoke flavor is your whole reason | Wood | Nothing else provides it, and be honest with yourself |
Our ranked picks split the same way: best outdoor pizza oven leads with gas because that is what most people should buy, and best wood-fired pizza oven covers the live-fire field for people who want it.
Safety applies equally to both
This is not a place where gas is safer than wood or the reverse — both produce carbon monoxide, a gas with no smell, no color and no taste. The NFPA's carbon monoxide guidance and the CPSC Carbon Monoxide Information Center are consistent about fuel-burning appliances: outdoors, in open air, always.
- Never indoors, and never in a garage — an open garage door does not make a garage outdoors.
- Never under a low, enclosed or unventilated cover — solid-roof pergola, panelled gazebo, patio umbrella above the chimney, screened porch.
- Keep well clear of structures and overhangs. These ovens run hundreds of degrees hotter than a grill; siding deforms, eaves scorch, and a wood chimney throws heat and sparks straight up. Our clearance guide applies with more margin.
- Non-combustible, stable surface only, and nothing combustible within arm's reach.
- Never leave a lit oven unattended, and never bring a warm oven inside to cool.
- Wood adds two hazards gas does not: sparks from the chimney, and ash that holds live embers for a day or more. Empty ash cold, into a lidded metal container, outdoors.
- Gas adds one wood does not: a hose and regulator to inspect. Check for cracks and abrasion each season, test connections with soapy water, and never look for a leak with a flame.

The short answer
Buy gas unless the fire itself is the reason you want the oven. If it is, buy multi-fuel and buy both burners — you will make better wood-fired pizza because you will not be forcing a wood session on a night you do not have the patience for it, and the oven will still be in use in three years.
