Ooni Karu 12 Multi-fuel Outdoor Portable Pizza Oven - Reaches 950F, Wood or Propane Gas Fired with Pizza Stone Review (2026)

Who the Karu 12 is built for

The Karu 12 is aimed at home cooks who want Neapolitan style pizza without committing to a permanent masonry oven. It burns wood or charcoal out of the box, and Ooni sells a separate gas burner attachment for anyone who wants to switch to propane on busy weeknights. At just under 27 pounds unboxed, it is light enough to carry to a driveway cookout, a campsite or a friend's backyard, and the folding legs with non slip feet make it stable on a table or a stand. Anyone who mainly wants sheet pan or pan pizza, or who cannot commit to feeding a fire during the cook, will find a gas only or electric oven easier to live with day to day.

Specs and design explained

The body combines a stainless steel shell with ceramic fiber insulation to hold heat, while the back panel and front nose are aluminum and the viewing door is borosilicate glass so you can watch the bake without opening the oven. Inside sits a 15mm cordierite stone that reaches the oven's 950F ceiling and cooks a 12 inch pizza in roughly 60 seconds once it is fully heated. A removable chimney with an adjustable vent lets you control airflow and smoke, and a quick access fuel hatch on the side makes it easy to add wood chunks or charcoal mid cook without losing much heat through the front opening.

Setting it up and living with it

Setup is mostly unfolding the legs and sliding the chimney into place, since the oven ships assembled. Day to day use means feeding small wood pieces or charcoal through the side hatch and adjusting the chimney vent to tune the flame and smoke level, then watching the pie through the glass window rather than opening the door and losing heat. Because the fuel hatch and mouth are sized for a 12 inch pizza, a narrower turning peel makes launching and rotating easier than a standard wide peel. Ooni backs the oven with a 5 year warranty when bought direct and a 60 day buyback offer if a pizza does not turn out well, and the stainless and aluminum panels wipe down once cooled rather than needing seasoning like a steel plate.

Trade-offs against other kit and gas ovens

Against Ooni's own Koda 16, which is gas only and built for a larger 16 inch pizza, the Karu 12 trades some cooking area for the flexibility of wood, charcoal or optional gas in one body. Against a Chicago Brick Oven CBO-500 kit, the Karu 12 is a finished, portable appliance you can use the same day, while the CBO-500 is a heavy refractory core you build into a permanent outdoor kitchen over a weekend. The trade-off with the Karu 12 is that the propane path is not included, so anyone who wants gas from day one should budget for the separate burner accessory before ordering.

Verdict and who should look elsewhere

With our score of 8.4 out of 10, the Karu 12 earns its place as a flexible, portable wood and charcoal oven that can grow into a gas setup later. It suits anyone who values real fire flavor and fast, hot bakes over ultimate convenience. Shoppers who want gas ready right out of the box should look at a Koda style propane only oven instead, and anyone planning a permanent backyard build that never moves again is better served by a brick oven kit like the CBO-500. For a first portable pizza oven that can travel and still hit serious Neapolitan heat, the Karu 12 remains a strong pick.
