Ooni Karu 2 Pro Multi-Fuel Pizza Oven | Wood and Gas Outdoor Pizza Oven with Integrated Thermometer, Makes 16" Pizzas Review (2026)

Who the Karu 2 Pro is for

The Karu 2 Pro is aimed at households that regularly cook full-size pizzas and want room for cast iron pans or roasts alongside them, since its cooking area is built around 16 inch pies rather than the 12 inch capacity of the standard Karu 2. It suits cooks who want the same wood, charcoal, or optional gas flexibility as the smaller model but need more headroom and throughput for entertaining. Because of its size and weight, it works best for a fixed spot on a patio rather than an oven that gets loaded into a car for weekend trips. Occasional pizza makers who cook for one or two people are likely better served by the smaller, lighter Karu 2.

Size, capacity, and heat

The Karu 2 Pro measures roughly 31.9 by 19.7 by 32.7 inches and weighs about 63 pounds, notably larger and heavier than the standard Karu 2. Its internal cooking surface is sized for 16 inch pizzas, giving enough headroom for whole roast chickens or other larger dishes, not just flatbreads. Ooni states it can reach up to 950F and cook a pizza in about 60 seconds using wood or charcoal, with a gas burner attachment available that the brand says fits in under a minute for switching fuels. A front-mounted digital temperature hub gives an instant readout, which is a step up from the built-in analogue-style thermometer on the standard Karu 2.

Everyday use and switching fuels

Day to day, running the Karu 2 Pro on wood or charcoal means managing a solid fuel fire much like other multi-fuel ovens, with the larger firebox needing correspondingly more fuel to reach and hold temperature. The digital display takes some of the guesswork out of knowing exactly when the stone is ready, which matters more at this size since a larger stone takes longer to heat evenly. Because the gas burner is a separate attachment, switching between wood-fired flavor and gas convenience is possible without buying a second oven, though it does add to the total cost over the base unit. At 63 pounds, moving the oven once it is set up on a patio is a two-person task rather than something done casually.

How it compares with the rest of the lineup

Against the standard Karu 2, the Pro trades portability for capacity, roughly doubling the weight in exchange for room to cook 16 inch pizzas instead of 12 inch ones and adding the digital temperature hub. Compared with Bertello's SimulFIRE bundle, which combines wood fire and a gas burner with a peel and cover included, the Karu 2 Pro leans on Ooni's larger build and digital readout rather than an all-in-one accessory bundle. For a household that has already decided it wants the biggest pizzas an outdoor oven can realistically produce at home, the Karu 2 Pro is one of the more complete options in this size class.

Verdict and who should choose smaller

The Karu 2 Pro rewards households that entertain often, want 16 inch pizzas, and have a permanent spot for a larger oven, backed by genuine multi-fuel flexibility and a digital temperature display that simplifies timing. It is not the right choice for anyone prioritizing portability or a smaller footprint, since its size and weight are built for staying put. Buyers who mostly cook for one or two people, or who want to move the oven between locations often, should look at the standard Karu 2 instead, which keeps the same fuel flexibility in a lighter, more compact body.
