At a glance

One-line verdict

A proper multi-fuel pizza oven for people who want 60-second pizzas, provided they accept that the gas route involves buying another bit of kit.

Best for

Garden cooks who want 12-inch pizzas fast and value choosing between wood, charcoal and an optional gas setup.

Skip it if

Skip it if buying a separate gas burner or managing a 12kg outdoor oven sounds like admin rather than a lovely Saturday plan.

The full picture

The Ooni Karu 12 exists for a particular kind of domestic escalation: someone makes a decent pizza at home once, then decides their regular oven is an affront to civilisation. We think that instinct is mostly ridiculous, but also entirely understandable. A crisp, fast-fired pizza has a way of turning an ordinary garden meal into an event, complete with flour on the patio and one person appointed Minister for Turning.

This is a 12-inch outdoor multi-fuel pizza oven, designed to run on wood or charcoal. Gas is also an option, though it requires Ooni’s separately sold burner. That is a meaningful choice rather than a decorative line on a box: wood and charcoal bring the fire-tending ceremony, while gas offers a more controlled-looking route for cooks who would rather not conduct a tiny volcano after work.

Ooni states that the Karu 12 reaches 450°C in as little as 15 minutes, climbs to 500°C, and can cook a pizza in as little as 60 seconds. Those figures explain its appeal. This is not a gadget for gently warming a supermarket pizza while apologising to it; it is built around the high-heat, quick-bake style people actually mean when they start talking about buying a pizza oven.

There is faff, naturally. At 12kg, with unboxed dimensions of 80cm by 40cm by 77cm, it needs somewhere sensible to live between performances. Nor is a thermometer built in. Still, the Karu 12 earns our pick because it puts the core pizza-oven fantasy in a manageable 12-inch format, while leaving buyers a genuine fuel choice instead of making them pledge allegiance to one barbecue religion.

The Irresistible

  • Its wood-or-charcoal setup, plus optional gas burner compatibility, makes the Karu 12 unusually flexible for an outdoor pizza oven.
  • The stated 500°C maximum and as-little-as-60-second pizza time are the whole point: proper high-heat cooking rather than patio theatre with a long waiting list.
  • A 12-inch pizza format is broad enough for the pizzas most people actually make, without turning the garden into a commercial kitchen annex.

The Clever Part

  • Ooni specifies a stated ideal baking temperature of 450°C in as little as 15 minutes, which makes spontaneous pizza plans less absurd than they usually are.
  • At 12kg, the oven remains movable for outdoor use, even if it is not the sort of object one casually lugs around while holding a drink.
  • The standard one-year warranty can be extended to five years through registration at Ooni.com.

The Fine Print

  • Gas compatibility is not included with the base oven: the gas burner is a separate purchase.
  • There is no built-in thermometer, so buyers wanting temperature confirmation need to account for that separately.

The Reality Check

  • Its 12kg weight and 80cm by 40cm by 77cm unboxed dimensions demand proper outdoor storage and a stable cooking spot; tiny-flat dwellers may admire it from a safe distance.

Buyer questions answered

Can the Ooni Karu 12 use both wood and gas?

Yes: the Ooni Karu 12 uses wood or charcoal, and it can use gas with Ooni's optional gas burner. The burner is sold separately, because apparently pizza night needs an expansion pack.

What size pizza does the Ooni Karu 12 cook?

The Ooni Karu 12 is a 12-inch pizza oven. That is a usefully civilised size: enough pizza to share, or not, depending on the week.

How quickly does the Ooni Karu 12 cook a pizza?

Ooni specifies that the Karu 12 can cook a pizza in as little as 60 seconds. Attention is therefore required; this is not an oven for wandering off to locate the grater.

How hot does the Ooni Karu 12 get?

The Ooni Karu 12 has a stated maximum temperature of 500°C (950°F) and reaches its stated ideal baking temperature of 450°C in as little as 15 minutes. It does not include a built-in thermometer.
