The verdict

The Ooni Karu 12G is a fantastic entry point for home pizzaiolos who want restaurant-quality, high-heat pizza without the hassle of wood or charcoal. Its gas-powered design offers convenience and speed, though the compact 12-inch surface is best suited for personal-sized pizzas rather than large family pies. For patios, balconies, or on-the-go cooking, it's a reliable and portable choice.

Our full review

The Ooni Karu 12G is a gas-powered outdoor pizza oven designed for anyone who wants professional-style, wood-fired-tasting pizza without the hassle of tending charcoal or logs. Compact and portable, it reaches temperatures of up to 500°C (932°F) in as little as 15 minutes, allowing you to cook an authentic Neapolitan-style pizza in just 60 seconds. Built with a durable stainless steel exterior and a rotating stone baking board, the Karu 12G ensures even heat distribution for a perfectly crisp base and beautifully charred crust every time. Its L-shaped gas burner sits at the rear of the oven, pushing heat up and over the cooking surface, mimicking the airflow of traditional wood-fired ovens while giving users precise, consistent control over their cooking temperature.

What sets the Ooni Karu 12G apart is its flexibility—while it runs primarily on gas via an easy-connect propane attachment, it retains the option to burn wood or charcoal for those who want to experiment with different flavor profiles. This dual-fuel versatility makes it a favorite among home cooks who appreciate the convenience of gas but still crave the smoky depth that solid fuel can bring. The oven’s compact footprint means it fits easily on a patio table, balcony, or countertop, without sacrificing the performance you’d expect from a larger, bulkier outdoor cooking setup. Its foldable legs and lightweight build (under 12kg) also make it simple to transport for camping trips, tailgates, or backyard gatherings, so pizza night is never confined to just one location.

Beyond pizza, the Karu 12G’s high heat retention and spacious 12-inch cooking surface make it suitable for searing steaks, roasting vegetables, and baking flatbreads, expanding its role from a specialty appliance to a versatile outdoor cooking tool. The included digital thermometer and viewing window allow users to monitor internal temperatures without opening the door and losing heat, ensuring consistent results with every bake. Ooni’s accompanying app and recipe guides further support beginners and seasoned pizzaiolos alike, offering dough recipes, temperature guides, and cooking tips tailored specifically to the Karu 12G’s capabilities. With its blend of portability, multi-fuel functionality, and consistently high-quality results, the Ooni Karu 12G stands out as a reliable, restaurant-quality pizza oven built for everyday backyard use.

What buyers say

— Marco T. (2024-03-12) I was intimidated by wood-fired ovens, so the gas version was perfect. Preheats fast and the crust comes out perfectly charred every time.
— Jenna R. (2024-01-25) Love how portable this is for camping trips. Just wish the stone was a bit bigger for family-sized pies.
— Diego M. (2023-11-08) Hooked up the propane tank and had my first pizza cooking in under 15 minutes. The gas burner keeps the temperature steady, which is a huge plus.
— Sarah K. (2023-09-30) Doesn't take up much space on my balcony, and it gets seriously hot. Just be careful, the exterior heats up fast.
