Countertop appliances usually end up in one of two places. They either become a permanent fixture on your kitchen island, or they’re relegated to that awkward corner cabinet behind the salad spinner you used once in 2019. The Ninja Foodi Grill 6 in 1 is a weird one. It’s bulky. It’s loud. It’s basically a high-powered wind tunnel that happens to sear steaks. But after the initial hype dies down, most people realize they aren’t even using it for what it was actually designed to do.
The Smoke Control Myth and Why Your Kitchen Still Smells Like Bacon
Ninja markets this thing as "virtually smoke-free." That's a bold claim. If you’ve ever tossed a marinated ribeye onto the grate at the "Max" setting, you know that "virtually" is doing a lot of heavy lifting in that sentence. The technology relies on a combination of a temperature-controlled grill grate, a splatter shield, and a cool-air zone. It works, mostly.
But here is the reality.
If you don't clean the mesh splatter shield after every single use, your kitchen will look like a 1950s jazz club within ten minutes. Grease builds up behind that screen. When the 500°F air starts whipping around during your next meal, that old grease vaporizes. You aren't smelling your current dinner; you're smelling last Tuesday’s pork chops.
People often complain about the smoke, but they rarely talk about the oil. You can't just use any fat. If you use extra virgin olive oil or butter, you’re asking for trouble because their smoke points are too low for the "Grill" setting. You need avocado oil or grapeseed oil. It’s a small detail, but it’s the difference between a perfect sear and a 9:00 PM smoke alarm solo.
Is the Ninja Foodi Grill 6 in 1 Actually an Air Fryer?
Sorta. But not really.
If you already own a dedicated Ninja Foodi 2-Basket Air Fryer, this machine might feel like a downgrade in terms of capacity. The 6-in-1 model (officially the AG301 or its various iterations like the Pro or XL versions) uses a 4-quart basket. It’s circular. Or rather, a rounded square.
The heat distribution is different. In a standard air fryer, the goal is purely convection. In the Ninja Foodi Grill 6 in 1, the heating element is situated directly above the grill grate, which is a massive hunk of high-density aluminum. This means you’re getting radiant heat from the top and conductive heat from the bottom.

Everything cooks faster. Seriously.
If a recipe says 20 minutes, check it at 12. The air velocity in this unit is higher than many standalone air fryers. This is great for getting wings crispy, but it’s a nightmare for delicate baking. If you try to bake a cake using the "Bake" function, the top will often set and brown long before the middle has even thought about rising. You have to treat it more like a tiny, aggressive convection oven than a traditional baker.
The Six Functions: Use Them or Lose Them
Most owners stick to "Grill" and "Air Crisp." That’s a waste of counter space. The six functions usually include:
- Grill
- Air Crisp
- Roast
- Bake
- Broil
- Dehydrate
Let's be honest about "Dehydrate." It takes six to eight hours to make a handful of beef jerky. The fan is running the whole time. It’s cool that it can do it, but unless you’re a patient person with a low electricity bill, you probably won't.
The "Roast" setting is the sleeper hit. Everyone ignores it. While "Air Crisp" blasts the fan at maximum speed to dry out the surface of food, "Roast" uses a slightly lower fan speed. This is what you want for a whole cauliflower or a small chicken. It allows the heat to penetrate the center without turning the outside into leather.
The Cleaning Problem Nobody Mentions
They say the parts are dishwasher safe. Technically, that is true. The ceramic-coated grill grate, the crisper basket, and the cooking pot can all go in the bottom rack.
Don't do it.

Ceramic coating is finicky. Over time, the high heat and harsh detergents in dishwasher tabs will micro-pit the surface. Eventually, your "non-stick" grill grate starts acting like Velcro for salmon skin. If you want this thing to last five years instead of eighteen months, you have to hand wash it.
The real pain point is the internal heating element. You can’t submerge the lid. Over months of use, grease mists onto the heating coils. Since you can’t easily scrub them, they carbonize. This is where that "old kitchen smell" comes from. Professional tip: once the unit is completely cool, take a damp microfiber cloth with a tiny bit of lemon juice or vinegar and wipe the area around the fan. Just stay away from the actual bulb or element.
Comparison: The 6-in-1 vs. The XL Pro
If you're looking at the Ninja Foodi Grill 6 in 1, you've probably seen the XL Pro version with the built-in thermometer. Is it worth the extra fifty bucks?
Honestly? Yes.
The standard 6-in-1 is a "guess and check" machine. You're constantly lifting the lid—which lets all the heat out—to poke the meat with a handheld thermometer. The XL Pro has a leave-in probe that shuts the machine off when the steak hits 135°F. If you cook a lot of protein, the base model feels a bit primitive by comparison. However, the base model is significantly smaller. If you’re in a city apartment with limited counter depth, the XL will feel like you’ve invited a small tank to live in your kitchen.
What it Does to Your Electric Bill
It’s a 1760-watt appliance. That’s roughly the same as a high-end hair dryer or a space heater. Because it cooks so much faster than a standard oven—which usually needs 15 minutes just to preheat—you actually end up saving money on energy in the long run.
A standard oven takes about 2000-5000 watts. If you’re roasting a few chicken thighs, heating up that giant cavernous metal box is wildly inefficient. The Ninja Foodi Grill 6 in 1 preheats in under eight minutes. For a two-person household, it’s the more economical choice, despite the high wattage.

Real World Performance: The Steak Test
The main reason people buy this is the grill marks. It’s the "Cyclonic Grilling Technology."
Does it taste like a charcoal grill? No. Of course not. There’s no combustion. There’s no wood smoke. You’re missing the chemical reaction that happens when fat drips onto glowing coals and sends flavor-packed smoke back up into the meat.
But, does it taste better than a pan-seared steak? Frequently, yes. Because the air is circulating, you get an evenness of "doneness" that is hard to replicate in a cast-iron skillet without a lot of butter basting. The grill marks are aesthetic, but they do provide that bitter, charred crunch that people crave.
Technical Nuance: The Altitude Factor
Here is something you won't find in the manual. If you live in a high-altitude city like Denver, the Ninja Foodi Grill 6 in 1 behaves differently. Because the air is thinner, the convection fan is less effective at moving heat. You might find that your "Air Crisp" times need to be extended by 10-15%. Conversely, the "Grill" function, which relies more on the physical contact with the grate, stays fairly consistent.
Actionable Steps for New Owners
If you just unboxed your Ninja Foodi Grill 6 in 1, or you're about to buy one, stop looking for recipes and start mastering the mechanics.
- Deep clean the splatter shield every 3 uses: Don't wait for it to turn brown. Soak it in hot soapy water immediately after the machine cools down.
- Ignore the "Air Fryer" time charts: Most frozen food bags give instructions for standard air fryers. Take 3 minutes off whatever they suggest.
- The "Dry Rub" Rule: Avoid sugary rubs (like honey-based BBQ) on the Grill setting. The sugar will burn and stick to the ceramic before the meat is cooked. Save the sauces for the last 2 minutes of cooking.
- Preheat with the lid closed: The machine won't let you skip the preheat anyway, but make sure the grill grate is inside during the process. If you put a cold grate into a hot machine, your food will stick instantly.
- Give it space: This unit vents a significant amount of hot air out the back. If you push it right up against a tiled backsplash or underneath a low-hanging wooden cabinet, you're going to end up with condensation issues or, worse, warped cabinetry. Pull it out toward the edge of the counter when in use.
The Ninja Foodi Grill 6 in 1 isn't a magical device that replaces a chef. It’s an aggressive, high-heat convection tool. If you respect the smoke point of your oils and keep the sensors clean, it makes better protein than almost any other indoor solution on the market. Just don't expect it to be a quiet or "set it and forget it" experience. It’s loud, it’s fast, and it demands your attention.
