The Karu 16 is Ooni's do-everything flagship: 16-inch multi-fuel with a glass door, digital thermometer, and the capacity for serious pizza parties. It's the most capable portable oven on the market, but the $599 price (plus $100 for the gas burner) means you're paying a premium for that versatility.
Best for: experienced pizza makers who want a large multi-fuel oven that does everything
Key Takeaways
The Ooni Karu 16 is what happens when you take everything people loved about the Karu 12G and scale it up. Sixteen-inch stone for party-sized pies. ViewFlame glass door for monitoring without heat loss. Digital thermometer for precise readings. Multi-fuel capability for wood purists and gas pragmatists alike. On paper, it's the perfect oven.
In practice, it's very close. The 16-inch stone handles any pizza size you'd reasonably make at home. The glass door is a legitimate upgrade over the Karu 12G's already-good ClearView version — the ViewFlame coating sheds soot even more effectively. The digital thermometer (reading stone and ambient) removes the guesswork that plagues cheaper ovens. And the build quality is noticeably more robust than the Karu 12G, with denser insulation and a more substantial feel.
The honest catch: this is a $699 oven if you want multi-fuel capability. The base $599 gets you wood and charcoal only. The gas burner is another $100, and you'll almost certainly want it for weeknight convenience. At $699 all-in, you're in Gozney Dome territory (which starts at $1,799 but is a different class of oven). And at 62 lbs, "portable" is generous — it's movable, but you're not tossing this in the car for a casual outing.

On gas, the Karu 16 performs nearly identically to the Koda 16. The 29,000 BTU burner gets the stone to 900°F+ in about 15 minutes, and Neapolitan pies cook in 60-90 seconds with excellent char. The L-shaped burner provides the same improved heat distribution as the Koda 16. If you're running gas 90% of the time, the Koda 16 is the smarter buy — same performance, less weight, $100 cheaper.
Wood-fired is where the Karu 16 justifies itself. The larger fuel tray (210 cubic inches) holds substantially more wood than the Karu 12G, which means less frequent feeding during a multi-pizza session. The bigger firebox generates more consistent heat across the 16-inch stone than any 12-inch multi-fuel oven can achieve. A well-managed wood fire in the Karu 16 produces the most authentic wood-fired Neapolitan available in a portable format.
The glass door makes a bigger difference than you'd expect. Being able to visually monitor your pizza without cracking the door (and losing 50-100°F of heat each time) means fewer burnt crusts and more confident cooking, especially when you're learning.
The Karu 16 is built like a serious piece of equipment. Triple-layered insulation (ceramic fiber, calcium silicate board, stainless steel reflector) retains heat significantly better than the Karu 12G. The carbon steel shell with powder coating is the same spec as the rest of the Ooni lineup. The hinged door with ViewFlame glass feels substantial and well-engineered.
The digital thermometer is built into the oven — no aftermarket IR gun needed. It reads stone temperature and ambient air temperature, giving you the data to make informed decisions about when to launch and when to wait.
At 62 lbs, the build quality also means heft. This is a two-person carry. The folding legs and carry handles help, but it's not a grab-and-go appliance. Think of it as semi-portable: fine for moving around the yard or driving to a friend's house with some effort, but not practical for casual transport.
Assembly is about 30 minutes — chimney, door, thermometer probe, and legs. Nothing complex, but more involved than the Koda series' zero-assembly design. Once assembled, gas operation mirrors the Koda 16: turn on, wait, cook.
Wood-firing has the same learning curve as any wood oven, amplified slightly by the larger firebox. You need more wood to fill the space and maintain temperature, but the larger fuel capacity means you're feeding less frequently. The digital thermometer takes much of the guesswork out of fire management — you can see exactly when your stone is ready and when you're losing temperature.
The door is both a blessing and a minor annoyance. It's great for monitoring, but you need to open it every time you launch or retrieve a pizza, and the hinge mechanism requires two hands. Some users remove the door entirely during a high-output pizza session and reattach it between rounds.
Cleaning is standard for multi-fuel: minimal after gas sessions, moderate after wood (ash removal, soot wiping, chimney maintenance).
What We Love
What Could Be Better
“The glass door changed everything for me. I went from burning every third pizza to consistent results overnight. Being able to see what's happening without opening the oven is worth the upgrade from the Koda 16 alone.”

“We use gas on weeknights and wood on weekends. Friday night with a wood fire, homemade dough, and the ViewFlame glow — it's the highlight of our week. The oven makes it an experience, not just dinner.”

“At 62 pounds this thing is no joke to move. My wife and I carry it to the patio table together. It's portable in theory but in practice it lives in one spot.”
