Ooni Karu 2

In this ooni karu 2 review, the Ooni Karu 2 is the best upgrade pick for wood-fired cooks at $448.95, ranked fourth of nine in our 2026 outdoor pizza oven guide. It is a 12-inch multi-fuel countertop oven that runs on wood, charcoal or propane, holds 4.5 stars from 215 Amazon ratings, and hits 950°F in as little as 15 minutes. Buyers who already own a basic wood oven and want a glass door, a built-in thermometer and steadier airflow get the most from it. By contrast, anyone happy with a Karu 12 should skip it, because the pizza size and cook time are identical.

The day-to-day details explain the price. Its borosilicate glass door with ClearView technology lets you watch the crust brown without lifting the lid, so heat stays in the chamber and the stone stays hot between bakes. Meanwhile, the integrated thermometer shows the chamber temperature at a glance, which removes the guesswork that trips up first-time wood burners. The extra large fuel tray takes wood or charcoal for a traditional flame, or you can attach a gas burner sold separately for propane baking that uses 36 percent less gas than the previous generation. In practice, 950°F is the number that matters: at that heat a 12-inch pizza bakes in about 60 seconds. On top of that, the powder-coated body measures 29 by 16 by 28 inches and weighs 15.3 kg, so one person can move it.

Value is where the Karu 2 splits buyers. At $448.95 it costs roughly $200 more than the Karu 12 for the same 12-inch capacity, and the 1-year warranty is modest for an oven at this price. That said, the upgrade buys control, not size: a see-through door, a real thermometer and a bigger fuel tray that make wood-fired cooking repeatable instead of lucky. Even so, current Karu 12 owners should keep what they have and spend the difference on gas, because nothing here changes how big a pizza you can bake. For first-time buyers who want one oven for wood, charcoal and propane, it is the smarter long-term pick in our guide. If fast weeknight pizza and steady results matter more to you than saving $200, this is the one to get.
