Ooni Karu 12

· Easy to use

There are some basic steps you need to learn to keep this wood-burning oven rolling at adequate temperatures for your pizza. It’s no more difficult than starting a charcoal grill and using some common sense when it comes to getting your starter wood fired up. The experts make it seem easy, so the learning curve is keeping the fire going for the duration of anything you intend to cook in this pizza oven.

· Build quality

It’s well built for such a small wood-fired oven and features double insulation around the hood for this oven so you don’t get burned so easily. The heating insulation is made from the same stuff that is used for ceramic kilns, and can support heat upwards of 950 degrees Fahrenheit! It will cool off just as easily as it became hot since the stainless steel won’t retain heat for very long.

· Price

When it comes to professional standards, you can expect bargain basement pricing here for a top-quality product. You’ll find pricier BBQ accessories than this pizza oven for your money’s worth. What makes it worthwhile is that it’s priced to be competitive for any professional pizza oven and can become an expert tool in the hands of seasoned pizza artisans who like working on a budget.

· Fast pizza cooking

With higher temperatures that can be achieved in less than 15 minutes, it’s possible to cook a pizza in this oven within 2 minutes! This is ideal for cooking many other dishes inside a skillet including steaks, omelets, and other outdoor favorites.

· Portable for outdoors

This oven is assembled in less than 1 minute and has folding legs that allow it to sit on a tabletop or flat surface. It comes with a removable oven door to help keep the heat inside without substantial loss of temperature.

· Uses a variety of burning fuels

It’s perfectly fine to use small chunks of wood no bigger than your fist and lumps of charcoal to keep your temperature constant. While pellets are fine as well, the real flavors of hardwood like hickory or oak will add selective real flavor to any artisan pizza.

· Great heat retention and airflow

This oven has a lined upper hood which helps to deflect heat and keeps it from escaping easily. There is an air vent chimney that is controlled using a spring-bound smoke valve. This will further allow you to keep your fire going by adjusting this vent. It also features a pizza stone that is made from Cordierlite which is lightweight and doesn’t crack from thermal shock at all.

· Easily converts for gas burner

This model will allow for an additional add-on from Ooni that allows a gas burner attachment to fit inside the wood-burning chamber. It’s a nice option just in case the weather conditions aren’t so great for burning wood or charcoal.

· Comes with storage case

This portable oven comes with a travel case that covers the oven for transporting. You have to wait until the oven cools off after using it to put the cover back on.
