Best Multi-Fuel Pizza Ovens (2026): Wood, Gas, Your Call, Ranked

If you want one oven that does wood-fired spectacle and gas-fired convenience at full size, this is it. The Ooni Karu 2 Pro is the only 16-inch multi-fuel oven in this guide, and that matters: it cooks a true dinner-size pie at a ~950°F peak, fueled by wood or charcoal straight out of the box. The large glass door is the feature you don't appreciate until you have it, on a wood fire, being able to read the bake and watch the cornicione puff without opening the chamber and dumping heat is genuinely useful. It's a real wood-fired oven first, with the smoke character to match.

At 61.7 lb it's the heaviest oven in this roundup, call it stationary, and the wood-to-gas conversion means swapping the firebox for the gas burner rather than flipping a switch. That's the trade for doing both fuels properly instead of compromising on either. If you want the flexibility of wood when you have the time and gas when you don't, all on a full 16-inch floor with a door to watch through, the Karu 2 Pro is the most capable multi-fuel oven we'd put on a patio.

The Karu 2 keeps the part of the Pro that's hardest to find elsewhere, a glass door on a wood-fired oven, and trims the size and weight. The Ooni Karu 2 hits the same ~950°F peak, burns wood and charcoal out of the box, and takes the same optional gas burner for swap-to-gas convenience. What you lose versus the Pro is the 16-inch floor; what you keep is everything that makes a multi-fuel Karu worth owning, in a 33.7-lb body you can actually move.

The 12-inch ceiling is the only real compromise, and at $449 you're paying $100 over the Karu 12 mostly for the glass door and the refined design. For some cooks that window is worth it on its own, watching the leopard-spotting develop on a live fire is half the fun of wood. If you want the most refined portable Ooni multi-fuel and don't need a 16-inch pie, the Karu 2 is the one to get; if you'd rather save the money and skip the door, the Karu 12 is right below it.

This is the oven that gets people into wood-fired pizza without a second mortgage. The Ooni Karu 12 strips multi-fuel to its essentials: a wood-and-charcoal firebox, a 12-inch stone, and the same optional gas burner the rest of the Karu line uses. There's no glass door and the design is older than the Karu 2's, but it reaches the same ~950°F, and at 26.4 lb it's the lightest oven in this guide, carry it one-handed, store it on a shelf. For $349 it's the lowest-risk way to find out whether live-fire pizza is your thing.

The honest limits are what you'd expect at the price: no glass door, a 12-inch pie ceiling, and a wood fire you manage by feel and airflow rather than by watching through a window. None of that stops it from making excellent wood-fired pizza, it just asks a little more of you and gives you less to look at. As the cheapest, lightest honest entry into multi-fuel, the Karu 12 is the easiest yes in the category for a wood-first cook.

The Roccbox earns its place here as the gas-first path to multi-fuel. Where the Ooni Karus are wood ovens you can convert to gas, the Gozney Roccbox ships as a gas oven and adds wood via an optional burner, convertible, not simultaneous. That's the right framing for an honest pick: if you mostly want the dial-and-go ease of gas but like the idea of chasing wood-fired smoke later, this gets you there without buying a second oven. It packs Gozney-grade insulation and a silicone safe-touch shell into a portable 12-inch body, so it holds and recovers heat like an oven a size up, and you can grab the outside without a glove.

The compromises are size, weight, and the add-on math. A 12-inch pie is a personal-to-shared round, at 44 lb the Roccbox is dense for its footprint, and the wood burner is an extra purchase on top of the $499 oven. For a gas-first cook who wants the best heat retention in a small oven and the option to add real wood-fired smoke down the line, the Roccbox earns its long-running cult status, just don't buy it expecting wood out of the box.

The Pizzello is the budget oven that actually delivers on the simultaneous multi-fuel promise. Where the Ooni Karus make you swap a burner to change fuels, the Pizzello 16 is built to burn propane and wood in the same chamber, so you can hold a steady gas baseline and toss in a wood chunk for smoke and leoparding without touching the hardware. That's the dream version of multi-fuel for a lot of buyers, and getting it on a full 16-inch stone for $329 is genuinely remarkable. It cooks a true dinner-size pie at a ~930°F peak.

The compromises are the ones you'd expect at the price. The build is budget, fit and finish trail the Oonis and Gozneys, and at 50 lb it's a stay-put oven, and ~930°F, while plenty, is the lowest peak in the gas-capable field. But if your priority is a full-size pie with true propane-and-wood flexibility and you don't want to spend $800, the Pizzello 16 is the most oven for the money in this roundup.

This is the lowest-risk dollar entry into multi-fuel, and it's flexible to a fault. The BIG HORN 12 burns wood, gas, or pellet on a 12-inch stone, weighs just 24 lb, and costs $199, less than half the price of the cheapest Ooni multi-fuel. Its headline spec is a stated ceiling of up to ~1110°F, the highest number anywhere in this guide. We want to be honest about that figure: it's the manufacturer's claim, not a temperature we clocked, and budget ovens are where stated peaks and real floor temps diverge most. We'd buy this for the price and the fuel flexibility, not the headline number.

The compromises are the budget ones: fit, finish, and run-to-run consistency trail every pricier oven here, and a $199 multi-fuel oven is a gateway, not an heirloom. But the fuel flexibility is real, wood for flavor, gas for ease, pellet if you want a middle path, and for a first-timer who wants to learn multi-fuel without committing $349 or more, the BIG HORN 12 is the cheapest honest ticket in.

The KoolMore 32 is a different animal from the rest of this guide. Where everything above is a portable or luggable pizza oven, the KoolMore 32 is a 32-inch cart-style body that runs propane gas and wood fired, closer to a fixed outdoor cooking station than a grab-and-go oven. The big footprint is the point: this is for a patio or commercial-leaning setup where the oven lives in one place and the cart is part of the appeal. The gas-and-wood combo is built in, giving you weeknight gas and weekend wood without swapping hardware.

The trade-offs follow from the format. A 32-inch body is a big footprint and a fixed installation, not something you carry; and the missing peak-temp and pizza-size specs mean you're buying somewhat on faith until you've run it. For a cook who specifically wants a large-format, cart-style gas-and-wood combo for a permanent outdoor spot, the KoolMore 32 fills a niche none of the portable ovens here do, just go in with eyes open about the specs KoolMore leaves unstated.
