You want char grilled flavor on a weeknight, but the weather is miserable, your building bans open flames, and your last indoor sear set off the smoke alarm. A grill pan scorches unevenly and an outdoor grill is not an option for your space. That is the exact frustration the indoor grill and air fryer hybrid category was designed to solve.

Smart Cook System and Foodi Smart Thermometer Remove Guesswork
The headline feature is the Foodi Smart Thermometer paired with the Smart Cook System, and it changes how you approach proteins. You select one of four protein settings and choose from nine customizable doneness levels, then the system tracks internal temperature and alerts you exactly when to remove your food. For you, that means no more hovering, cutting into a steak to check color, or second guessing chicken. In our evaluation, the probe stayed accurate and the interface made rare to well done truly one touch.
You simply insert the thermometer into the thickest part of your protein, close the lid, and let the grill manage timing. The display counts down and signals carryover, so your steak rests properly instead of overcooking on the grate. If you often cook for mixed preferences, you can pull one steak at medium rare and leave another to reach medium well without juggling timers.
Cyclonic Grilling Technology and Smoke Control for Real Kitchens
Ninja uses 500°F cyclonic air combined with a 500°F grill grate to mimic outdoor char. The hot air circulates rapidly while the grate sears, so you get defined grill marks and sizzled edges rather than the steamed texture many indoor grills produce. For burgers, chops, or veggies, you get browning and caramelization that looks and tastes like it came from a deck grill.
Smoke is the usual deal breaker indoors, and here the Smoke Control System makes a noticeable difference. A temperature controlled grate, splatter shield, and cool air zone work together with chef recommended practices to limit smoke at the source. You still want ventilation, but we found you can sear at high heat without filling your kitchen with haze or triggering alarms.
XL Family Sized Capacity and Genuine 6-in-1 Versatility
Capacity is where the XL designation earns its keep. The grill grate accommodates up to six steaks or up to 24 hot dogs at once, so you can cook mains and sides together instead of batching for a crowd. The included 4 quart crisper basket handles air crisping for fries or wings while the main grate stays free, which is ideal when you are feeding four to six people.
Beyond grilling, you get six versatile functions: Grill, Air Crisp, Roast, Bake, Broil, and Dehydrate, enabled by a wide temperature range. You can roast vegetables, bake a small tray of biscuits, broil for finishing, or dehydrate fruit chips without swapping appliances. It also transforms foods from frozen to perfectly char grilled in under 25 minutes, and air crisping uses up to 75% less fat when compared with hand cut, deep fried French fries, so you keep crunch with less oil. If you prefer stovetop searing for smaller portions, non-stick pans for everyday stovetop searing remain handy, but they cannot match this volume.
Build Quality, Design and Everyday Cleanup
The updated sleek design keeps the same functions you expect but feels more refined on the counter in black and silver. Controls are straightforward, with a clear dial and display that make switching between Grill and Air Crisp intuitive. The lid feels solid, the handles stay cool, and the overall footprint, while large, feels stable rather than bulky.
For daily use, the nonstick grill grate, crisper basket, and removable splatter shield are easy to wipe down and the shield helps contain grease. You will need dedicated counter space and storage for the probe, and the fan is audible when cyclonic air is at full power. Compared with a heavy cast iron skillet for high-heat searing, cleanup is faster and you avoid stovetop splatter, though you trade some of that skillet char depth for convenience.
Who Shouldn’t Buy This
You should skip this model if your kitchen is compact, you cook mainly for one, or you crave authentic charcoal or wood smoke flavor that only outdoor fuel delivers. Its XL size demands permanent counter space and it will not replicate true open flame aroma. In those cases, a compact air fryer or a smaller indoor grill will fit your space and budget better.
Verdict
If you want reliable indoor grilling with precise doneness, family sized capacity, and the flexibility to air crisp, roast, and more, the Ninja® Foodi® Smart XL 6-in-1 Indoor Grill & Air is an excellent all in one choice.

Frequently Asked Questions
Can the Ninja Foodi Smart XL Grill cook frozen steaks without defrosting?
Yes, it is designed to go from frozen to char grilled in under 25 minutes using the Grill function and cyclonic heat. You do not need to thaw overnight, which is helpful for last minute dinners in 2026. For best results, use the thermometer to confirm doneness and let the protein rest briefly after cooking.
How does the Smart Cook System know when my food is done?
You insert the Foodi Smart Thermometer into your protein, select the protein type and your preferred doneness on the control panel, and the system monitors internal temperature continuously. It alerts you when to remove the food and accounts for carryover cooking, so you get consistent results from rare to well done without cutting or guessing.
Do I still need an air fryer if I buy this 6-in-1 grill?
For most households, this unit replaces a standalone air fryer because its Air Crisp function and 4 quart basket handle fries, wings, and vegetables with similar crunch. If you already own a dedicated air fryer, keep it only if you need to cook two air fried items at different temperatures simultaneously. Otherwise, this grill covers your needs and adds grilling and roasting, and pairing it with precise kitchen knives that hold an edge makes prep even faster.
