You’ve seen the ads. A sleek, burnt-orange and black box sitting on a patio, puffing out artisanal-looking smoke while some guy pulls out a blistered Neapolitan pie in three minutes. It looks cool. It looks easy. But honestly, most "all-in-one" kitchen gadgets are kind of a letdown. They try to do everything and end up doing nothing well. So, when the Ninja Woodfire Outdoor Oven (the official name for that 8-in-1 beast) hit the market, I was skeptical. I’ve spent years messing around with Ooni stones and Weber grill hacks, and I know that high-heat cooking is finicky.
But here’s the thing: this isn’t just a pizza oven. It’s an electric roaster, a smoker, and a high-heat broiler that just happens to hit 700°F.
Most people get the Ninja 8 in 1 pizza oven because they want "easy pizza," but they stay for the way it handles a three-pound tri-tip. It’s a weirdly versatile machine. It doesn't use propane. You don't have to mess with charcoal chimneys. You just plug it in. In a world where authentic wood-fired cooking usually requires a degree in fire management, Ninja is basically betting that you’d rather just press a button and drink a beer while the machine does the math.
The Heat Reality: Can an Electric Oven Actually Do 700 Degrees?
Standard indoor ovens top out at maybe 500°F or 550°F if you’re lucky. To get that "leopard spotting" on a pizza crust—those little charred bubbles—you need floor temps that make standard kitchen insulation melt. The Ninja 8 in 1 pizza oven claims to hit 700°F.
Does it? Yes.
But there’s a catch.
Heat is about more than just a number on a digital screen. In a traditional wood-fired brick oven, you have massive thermal mass. The bricks hold the heat. In this Ninja unit, you’re relying on a high-density electric element and a custom-fit pizza stone. If you leave the door open for thirty seconds while you’re struggling to launch your dough, that temperature is going to plummet. You have to be fast.
The heat distribution is actually pretty clever. Unlike a traditional grill where the heat comes primarily from the bottom, this thing uses a fan to circulate air—basically a high-powered convection system—which helps cook the toppings at the same rate as the crust. Ever had a pizza where the bottom was burnt but the onions were still raw? This machine mostly fixes that.
It Isn't Just for Pepperoni
The "8-in-1" label isn't just marketing fluff, though some settings are definitely more useful than others. You’ve got Pizza, Specialty Roast, Max Roast, Broil, Bake, Smoker, Dehydrate, and Keep Warm.

I’ve found that the Max Roast setting is the real sleeper hit here.
Imagine you’re doing a tray of Mediterranean chicken and vegetables. In a normal oven, it takes 40 minutes and everything gets kind of soft. In the Ninja, at 600°F+? It’s done in twelve minutes. The skin on the chicken gets glass-shatter crispy while the inside stays weirdly juicy because the cook time is so short the moisture doesn't have time to escape.
Then there’s the "Woodfire Technology" part. This is where Ninja puts a little side-box for wood pellets. It’s not a pellet grill in the sense that it uses wood for fuel; it’s still 100% electric. The wood is just for flavor. You throw in a scoop of pellets, a tiny heating element ignites them, and a fan blows that smoke over your food. It’s subtle. You aren't going to get a Texas-style brisket bark in this thing, but for a 30-minute smoked salmon fillet? It’s incredible.
Why the Design is Kind of Genius (and Kind of Annoying)
The footprint is small enough to fit on a standard potting bench or a small patio table. That’s a win. But it’s heavy. You aren't going to want to lug this from the garage to the yard every time you want a snack. It needs a permanent home.
The cord is also surprisingly short.
Ninja clearly did this for safety—they don't want people running 50-foot thin extension cords that might overheat under the heavy amp draw of a 700-degree oven. If you’re planning your outdoor kitchen setup, keep the outlet location in mind. You’ll probably need a heavy-duty, 12-gauge extension cord if you aren't right next to a plug.
Mastering the Ninja 8 in 1 Pizza Oven: The Learning Curve
Don't let the "easy" marketing fool you into thinking your first pizza will be perfect. It won't be. My first three were disasters. One was a literal fire because I used too much flour on the bottom of the crust (flour ignites at these temps). Another was raw in the middle because I loaded it with too many watery vegetables.
Here is the actual secret to success with this machine: The Preheat.

The display will tell you it's ready in about 15 minutes. Wait 25. You want that pizza stone to be heat-soaked all the way through. If the stone is "surface hot" but not "core hot," the cold dough will suck the energy right out of it, and you’ll end up with a floppy bottom.
Choosing Your Pizza Style
The Ninja 8 in 1 pizza oven has specific presets for different styles:
- Neapolitan: High heat, 3-minute cook. Use 00 flour.
- Thin Crust: A bit lower, more crunch.
- New York: That classic foldable slice.
- Pan Pizza: This uses a specialized tray (usually sold separately or in bundles) and it’s basically a Deep Dish dream.
- Frozen: Don't laugh. It actually makes a cheap frozen pizza taste like something from a pub.
The Neapolitan setting is the most temperamental. Because it’s so hot, the window between "perfect" and "carbon" is about fifteen seconds. You have to hover. You have to watch. Honestly, it’s half the fun.
Comparison: Ninja vs. Ooni vs. Traeger
If you’re looking at the Ninja 8 in 1 pizza oven, you’re likely also looking at an Ooni Karu or maybe a small Traeger.
The Ooni is for the purist. It runs on wood or gas and hits 950°F. If you want a 60-second pizza and you don't mind the steep learning curve of managing a live fire, the Ooni wins. But the Ooni is terrible at roasting a whole chicken. It’s a specialist.
The Traeger is a smoker. It can do "pizza," but it’s really just a wood-flavored oven that struggles to get high enough for a true sear.
The Ninja sits right in the middle. It’s the "Swiss Army Knife." It’s for the person who wants a pizza on Tuesday, a smoked rack of ribs on Friday, and a roasted leg of lamb for Sunday dinner, all without owning three different appliances.
The Maintenance Nobody Talks About
Grease is the enemy of this machine.

When you’re roasting at high speeds, fat splatters. In a normal oven, it just sits there. In a 700-degree Ninja, it smokes. If you don't wipe down the interior (once it’s cool, obviously) after a messy roast, your next pizza is going to taste like burnt bacon grease.
The pizza stone is also porous. Don't you dare wash it with soap. If you do, your next pizza will taste like Dawn Powerwash. Just scrape the burnt bits off with a bench scraper and call it a day. The high heat of the next preheat cycle will essentially sterilize it anyway.
Is It a Power Hog?
You might worry about your electric bill. Running a 1760-watt appliance for an hour isn't nothing, but compared to the cost of a bag of specialty hardwood charcoal or a tank of propane, it's actually pretty economical. In most US states, running this for an hour costs roughly 25 to 30 cents in electricity.
The real value isn't in the energy savings, though; it's in the time. There is zero cleanup for the "fuel." No ash to dump. No oily residue from propane combustion. Just turn the dial to "off" and go eat.
What Actually Goes Wrong?
I’ve talked to a lot of owners, and the most common complaint isn't the cooking quality—it’s the "Add Woodfire" button. Sometimes people forget to hit it, and they miss out on the smoke. Other times, the pellet hopper jams if you use off-brand, oversized pellets. Stick to the Ninja-branded ones or at least high-quality food-grade pellets that are small in diameter.
Also, the "Keep Warm" function is fine, but it can dry things out quickly because of the fan. If you're keeping pizza warm, put it on a rack, not directly on the stone, or the bottom will turn into a cracker.
Real-World Tips for Your First Week
I’ve made the mistakes so you don't have to. If you just unboxed your Ninja 8 in 1 pizza oven, do these three things immediately:
- Buy a Wood Launching Peel: The metal ones are great for taking pizza out, but dough sticks to metal like glue when you’re trying to put it in. A wooden peel with a little cornmeal or semolina is a lifesaver.
- Dry Your Mozzarella: If you’re using fresh mozzarella (the kind in water), slice it and let it sit on paper towels for an hour. If you don't, the Ninja’s intense heat will turn that water into a swamp on top of your pizza.
- The "Hole" Test: Before you put your pizza in, pick up one edge of the dough. If it doesn't hold its shape or feels too thin, it's going to tear on the stone.
The Verdict on the 8-in-1
The Ninja 8 in 1 pizza oven isn't a "gimmick" tool. It’s a legitimate high-heat convection oven that happens to be shaped like a toaster oven on steroids. It fills a very specific niche: the outdoor cook who wants professional results without the "hobbyist" level of effort.
It won't replace a $4,000 built-in masonry oven. It won't replace a massive offset smoker for a backyard BBQ competition. But for a random Wednesday night when you want a pizza that tastes better than anything you can get delivered, it’s hard to beat.
Actionable Next Steps
- Check your power source: Ensure you have a dedicated 15-amp or 20-amp outdoor circuit. This machine pulls a lot of juice, and sharing a circuit with a heavy-duty pool pump or another grill might trip your breaker.
- Source your flour: Order some "Antimo Caputo Pizzeria" (the blue bag) or "Tony Gemignani" flour. High-protein bread flour works, but these Italian flours are designed specifically for the 700°F+ temps the Ninja produces.
- Plan a "dry run": Before your first big dinner party, run a test with just a plain cheese pizza. Learn how the "launch" feels. Getting the dough from the peel to the stone is the only part of this process that requires actual physical skill.
- Get a thermometer: While the Ninja has an internal sensor, a cheap infrared thermometer gun is great for double-checking that the center of the pizza stone has actually hit your target temperature before you drop the dough.
