I remember the first time I hauled a Ninja Foodi Smart Grill out of its massive box. Honestly, it felt a bit like buying a spaceship just to go to the grocery store. It’s bulky. It’s heavy. It’s got more buttons than my first car’s dashboard. But after three years of searing ribeyes and air-frying frozen wings in my kitchen, I’ve realized that most of the "pro reviews" you see online are missing the point. They talk about the wattage or the ceramic coating, but they don't tell you about the smoke alarm going off at 11:00 PM because you used the wrong oil, or the way the "Smart" thermometer actually changes how you think about steak.
It’s not just a grill. It’s a solution for people who live in apartments and can’t have a Weber on the balcony, or for those of us who are just too tired to go outside and mess with charcoal when it’s raining.
The Meat of the Matter: How the Ninja Foodi Smart Grill Actually Cooks
Most people buy this thing for the "grill" part of the name. It makes sense. It comes with a heavy-duty, high-density grill grate that’s designed to mimic the heat retention of a traditional outdoor setup. Ninja uses what they call Cyclonic Grilling Technology. Basically, it’s a high-speed fan blowing 500°F air around the food while the grate sears the bottom.
Does it taste like charcoal? No. Let’s be real. Without wood or coal, you aren't getting that specific smoky profile. But does it give you those charred, caramelized grill marks? Absolutely.
The real magic, though, is the Leave-In Smart Thermometer. If you’ve ever cut into a steak only to find it’s still raw or—worse—gray and overcooked, this feature is your new best friend. You plug the probe into the side of the machine, stick the other end into the thickest part of your protein, and tell the grill you want "Medium Rare." The machine monitors the internal temperature in real-time. It even accounts for "carryover cooking," telling you to take the meat off a few degrees early because it knows the internal temp will continue to rise while the meat rests.

Beyond the Sear: It’s Secretly an Air Fryer
I’ll be honest: I use the air fry basket more than the grill grate. The Ninja Foodi Smart Grill is essentially a top-tier air fryer that just happens to be shaped like a chest. Because the heating element is so close to the food and the fan is so powerful, it crisps things up faster than my dedicated basket-style air fryer ever did.
- Brussels Sprouts: They get those charred, paper-thin edges that taste like candy.
- Frozen Fries: Total game changer. Five minutes and they’re better than most fast-food joints.
- Chicken Wings: You don't need oil. The fat in the skin renders out and fries the wing in its own juices.
The "Smart" part of the grill also applies here. You can dehydrate fruit for snacks or roast a whole small chicken. It’s versatile. But that versatility comes with a footprint. This thing is a counter-hog. If you have a tiny kitchen with limited prep space, you’re going to be moving this beast around a lot, and it’s not light.
The Smoke Problem (And How to Fix It)
Let’s talk about the one thing the manuals downplay: smoke. If you throw a fatty ribeye on a 500°F grate, you are going to get smoke. Physics doesn't care about marketing. Ninja includes a "Smoke Control System" which is really just a mesh splatter shield that snaps over the heating element. It helps. It helps a lot.
But it isn't perfect.

If you use olive oil or butter—oils with low smoke points—your kitchen will look like a 1970s pool hall within ten minutes. You have to use high-smoke-point oils like avocado oil or grapeseed oil. Even then, if you don’t clean that mesh screen after every single use, the old grease will burn and smoke the next time you turn it on. Honestly, cleaning the splatter shield is the worst part of owning this machine. It’s sharp, it’s greasy, and it requires a stiff brush and some serious elbow grease.
Pro-Tip for Maintenance
Don't just toss the plates in the dishwasher. Yeah, Ninja says they are dishwasher safe. Technically, they are. But the high heat and harsh detergents in a dishwasher will eventually degrade that non-stick ceramic coating. If you want this thing to last five years instead of two, hand wash the grate. Soak it in warm soapy water for ten minutes, and the burnt-on bits usually slide right off.
Why the Smart Thermometer is a "Must-Have" Feature
There are cheaper versions of the Ninja Foodi Grill that don't include the built-in thermometer. Don't buy them.
The difference between a $180 model and a $230 model (prices fluctuate, of course) is usually the "Smart" integration. Being able to walk away from the kitchen to fold laundry or watch the game while your pork chops cook—knowing the machine will literally beep and shut off when they hit 145°F—is the entire value proposition. It removes the guesswork. It removes the "poke and hope" method of cooking.

I’ve seen people complain that the thermometer is inaccurate. Usually, it's because of placement. If the tip of the probe hits a bone or a pocket of fat, the reading will be off. You have to find the "heart" of the meat. Once you master that, it’s flawless.
Real Talk: The Limitations
It’s not perfect. Nothing is.
- Noise: It sounds like a small jet engine taking off on your counter. If you’re trying to have a quiet conversation or listen to a podcast while you cook, you’re going to have to turn the volume up.
- Size: You can’t fit a huge amount of food on the grate. It’s perfect for two people. It’s doable for four. If you’re hosting a Super Bowl party and want to grill 20 burgers? You’re going to be standing there for an hour doing batches.
- The "Preheat" Wait: It takes about 8 to 10 minutes to preheat to the "Max" setting. For a machine that cooks a steak in 8 minutes, waiting 10 minutes for it to warm up feels like forever.
Is It Worth the Counter Space?
If you already own a high-end air fryer and a George Foreman grill, you probably don't need this. But if you’re looking to consolidate or if you’ve never been able to get a decent sear on a steak indoors, the Ninja Foodi Smart Grill is a genuine level-up for home cooks.
It bridges the gap between "microwave easy" and "chef quality." You aren't just heating food; you're actually cooking it, just with a safety net.
Actionable Next Steps
- Check Your Oil: Before you even plug it in, go buy a bottle of avocado oil. It has a smoke point of around 520°F, which is the only way to keep your smoke detectors quiet during a high-heat sear.
- Measure Your Space: Get a tape measure. This unit is roughly 17 inches deep and 11 inches tall. Make sure you have enough clearance under your upper cabinets, as the lid flips up and needs extra vertical room.
- Start with Salmon: If you want to see the "Smart" thermometer shine, try a thick salmon fillet. Set it to "Medium" and watch how it keeps the fish flaky and moist rather than turning it into a hockey puck.
- Deep Clean the Shield: Every 5-10 uses, soak the splatter shield in a mixture of baking soda and vinegar to break down the baked-on grease that a regular sponge can't reach.
