You finally bought it. That sleek, stainless steel Ooni wood fired pizza oven is sitting on your patio, looking like a piece of modern art, and you’re ready to channel your inner Neapolitan pizzaiolo. But then reality hits. Your first crust is charred on one side and raw in the middle. The fire keeps dying. You’re sweating, the kids are hungry, and you’re wondering if you just spent several hundred dollars on a very expensive outdoor ornament.
It happens to everyone. Honestly.
The Ooni isn't just a grill; it's a high-performance engine that demands a bit of respect and a lot of heat management. We’re talking about a machine capable of hitting 950°F (500°C) in about 20 minutes. That is blistering. Most home ovens tap out at 500°F. When you’re dealing with those kinds of temperatures, the margin for error is razor-thin. If you want that leopard-spotted crust and that unmistakable smoky "wood-fired" aroma, you have to stop treating it like a backyard BBQ.
The Fuel Myth: It’s Not Just "Wood"
Most people grab a bag of random kindling and hope for the best. Big mistake. If you’re using the Ooni Karu or the older Fyra models, you need to be surgical about your fuel.
Ooni recommends 100% hardwood pellets or kiln-dried hardwood kindling. Why? Because softwoods like pine contain resins. They’ll make your pizza taste like a campfire candle and soot up your stone faster than you can say "margherita." You want oak, beech, or ash. These hardwoods burn cleaner and, more importantly, they burn hotter.
Pro tip from the pros: If you’re using the Karu 12 or 16, don't just shove massive logs in there. You need pieces about 5 inches long and 1 inch thick. It’s all about surface area. Small pieces catch fast and create that rolling flame across the ceiling of the oven that cooks the top of your pizza while the stone handles the bottom.
Heat Management: The "Stone Cold" Truth
The biggest frustration for new Ooni wood fired pizza oven owners is the "soggy middle." You see the crust rising and browning, you pull it out, and the center is a floppy, doughy mess.
This happens because you’re looking at the air temperature, not the stone temperature.

You absolutely must buy an infrared thermometer. There is no way around this. You can’t eyeball 900 degrees. You need to point that laser at the center of the cordierite baking stone. If the stone isn't at least 750°F (400°C), don't even think about launching that dough. If the air is hot but the stone is cold, you get a burnt top and raw bottom.
Wait. Be patient. Give it 20 minutes to heat up, even if the built-in thermometer says it's ready. The stone is a heat sink; it needs time to soak up that thermal energy so it can "dump" it back into the dough the second they touch.
The Dough Is Your Engine
You can have the best wood-fired setup in the world, but if you’re using store-bought "bread dough" or high-sugar grocery store pizza dough, you’re going to fail. Most grocery store doughs are designed for 450°F home ovens. They contain sugar or oil to help them brown at lower temperatures.
In an Ooni? That sugar will burn to a bitter crisp in about 15 seconds.
You need "Type 00" flour. Antimo Caputo is basically the gold standard here. It’s finely milled and has a protein content that can handle the extreme heat without disintegrating.
Hydration matters too. For wood-fired cooking, a 60% to 65% hydration level is the sweet spot.
- 60% hydration: Easier to handle, less likely to stick to the peel.
- 70% hydration: Beautiful big bubbles (cornicione), but very sticky and prone to tearing.
If you’re a beginner, start low. Use 60% hydration. Your sanity will thank you when the pizza actually slides off the peel instead of turning into a "calzone-tastrophe" on the oven floor.

The "Launch" Anxiety
Launching the pizza is the most stressful five seconds of the entire process. We’ve all been there—the dough sticks to the peel, you shake it harder, the toppings fly into the back of the oven, and the dough bunches up into a "pizza-wreck."
Here’s the secret: Semolina flour. Don’t use regular flour on your peel. Regular flour burns and tastes like ash. Semolina is coarse, like tiny ball bearings. It lets the pizza glide. Also, work fast. The longer the dough sits on the peel with sauce on it, the more the moisture seeps into the dough, creating a "glue" effect.
Top it. Shake it (to make sure it's loose). Launch it.
The Five-Second Turn
Once that pizza is in the Ooni wood fired pizza oven, your job isn't done. You have approximately 60 to 90 seconds of total cook time. That’s it. If you walk away to get a beer, you’re coming back to a charcoal briquette.
Wait about 20-30 seconds for the back edge (near the flame) to firm up. Then, use a turning peel—those small circular ones—to rotate it 180 degrees. Keep it moving. The heat is directional. Unlike your kitchen oven which surrounds the food with steady heat, the Ooni is a blowtorch on one side. You are the manual rotisserie.
Cleaning and Maintenance (The Lazy Way)
People ask how to clean the pizza stone all the time. Honestly? Don't.
Don't use soap. Don't use water. Cordierite is porous; if it soaks up water and you heat it to 900 degrees, it can crack. If you have burnt cheese or flour on the stone, just flip the stone over the next time you use the oven. The extreme heat will "self-clean" the bottom side, burning off the residue through pyrolyzation. It’s basically a volcanic self-cleaning cycle.

Real-World Limitations
Let's be real for a second. Using an Ooni wood fired pizza oven in the middle of a Chicago winter or a rainy day in Seattle is a challenge. Wind is your enemy. If the wind blows into the mouth of the oven, it pushes the heat out the back and messes with the convection.
If it’s windy, position the oven so the back (the fuel vent) is facing the wind. This actually helps "push" the flames across the ceiling.
Also, wood-firing is a labor of love. If you’re hosting a party for 20 people, you will be standing by that oven the entire night. You won't be socializing. You’ll be a soot-covered pizza slave. If that doesn't sound fun, the Ooni gas-attachment (available for the Karu) is a lifesaver. You get the same heat with way less babysitting. But hey, we’re here for the wood-fired soul, right?
Moving Toward Mastery
If you really want to level up, start experimenting with wood types. Some enthusiasts swear by fruitwoods like apple or cherry for a sweeter smoke profile, though oak remains the king for consistent BTU output.
Check your gaskets. If you have a Karu 16, make sure the glass door is seated right. Clean the glass with a damp paper towel dipped in wood ash—it’s an old-school trick that cuts through creosote like magic.
Stop over-topping your pizzas. A heavy pizza is a pizza that won't launch. Two ounces of sauce, a few slices of fresh mozzarella, and a leaf of basil. That’s it. The Ooni is designed to celebrate the dough, not hide it under a mountain of toppings.
Actionable Steps for Your Next Bake
- Order a 12-inch infrared thermometer immediately. If you aren't hitting 750°F on the stone, your pizza will fail.
- Switch to "00" Flour. High-protein bread flour is okay in a pinch, but the texture of Italian "00" is what gives you that soft-yet-crispy finish.
- The "Cold Ferment" Trick. Make your dough 48 to 72 hours in advance and leave it in the fridge. This breaks down the starches into sugars, giving you those beautiful charred bubbles (leopard spotting) and a much deeper flavor.
- Pre-heat longer than you think. Give the oven a full 25 minutes to ensure the stone is saturated with heat.
- Dry your mozzarella. If using fresh mozzarella in water, slice it and let it sit on paper towels for an hour before cooking. Otherwise, you’ll end up with a "moat" of water in the center of your pizza.
- Keep the fuel small. Use thumb-sized pieces of kiln-dried oak to maintain a consistent, rolling flame without choking the firebox.
By mastering the balance between stone temperature and flame management, you’ll stop making "good for home" pizza and start making "better than the local shop" pizza. It takes about five or six "ugly" pizzas to get the rhythm down, but once you do, there’s no going back to the kitchen oven.
