Get more from your 12″ Dual Fuel Oven

Replace the cordierite floor that comes with your Ooni Karu 12 or 12G with an authentic Biscotto baking stone for a crisper crust, softer crumb, and a bigger, better cornicione, plus better heat retention for better roasting meats and better baking bread. And stop burning the bottom of your pizzas.


Our Biscotto stone can be easily installed in the Ooni Karu 12 or Karu 12G in just a few minutes — no tools required. Just slide it in.


Our Biscotto stone is 0.8″ (20mm) thick, that’s double the thickness of the standard 0.4″ (10mm) cordierite stone the comes with the Ooni Karu 12, and 33% thicker than the 0.6″ (15mm) stone that comes with the more expensive Karu 12G. You get a lot more heat retention for baking multiple pizzas in a roast and for roasting and baking bread. And you can stop worrying about burning the bottom of your pizzas.


Tired of baking one pizza and then having to wait for the oven floor to get hot again? A Biscotto baking floor absorbs and stores more heat (just like a battery), before evenly and gently releasing that heat to bake great pizzas. That means you can cooking multiple pizzas at a time.

The Ooni Karu 12/12G is a fun dual-fuel oven (if you purchase the optional gas burner) making it a fun and versatile oven. Get a thick Biscotto baking stone so your Ooni Karu 12/12G retains more heat for better roasting and better bread—and better pizza.


This the real deal—Biscotto stones made by hand in Sorrento using alluvial clay from Mount Vesuvius. These are the same baking stones used by the famous pizza oven manufacturers in Naples.

MORE ON THE OONI Karu 12G (That’s the more expensive one)

The Karu 12G has been given an Ooni makeover to bring it in line with the rest of the range. Instead of the old stainless steel finish, it now has the same sleek, powder-coated matt black shell as the 16. This doesn’t just look better but is more durable, scratch-proof, and weather resistant. Ooni also put a lot of thought into the usability of the oven and have made it as user-friendly as possible by adding heat-resistant handles everywhere you might need them, including on the oven door, the fuel tray, and the chimney baffle.

  • The world’s most advanced portable pizza oven
  • Borosilicate glass door to keep an eye on your pizza without releasing heat
  • ClearView™ technology prevents soot and ash buildup on the door
  • Use wood or charcoal for a traditional wood-fired experience, or attach a gas burner (sold separately) for easy propane-fueled baking that uses 36% less fuel than previous models
  • Maximum temperature of 950 °F/500 °C; cooks pizzas in just 60 seconds
  • Reach ideal baking temperature of 850 °F/450 °C up to 29% faster; as little as 15 minutes
  • Monitor temperature with the integrated thermometer
  • The SureGrab™ door handle stays cool to the touch
  • Cook 12-inch pizzas and more on the 15mm cordierite baking stone

The upgrade of the Karu 12 has effectively turned it into a smaller version of the Karu 16 multi-fuel oven. The Karu 16 is my top-rated pizza oven, and this new mini version has some great features that the original Karu 12 lacked. This update goes a long way to closing the gap between the two models. I wasn’t a huge fan of the original Karu 12 because using it seemed clunky – the solid door means you can’t see progress on cooking. Because of this, you had to cook with the door completely removed, allowing excess heat to escape. The door was also removable and not hinged, like the current models. So overall, I’m thrilled with this remodel and think it could turn into one of Ooni’s best sellers..
