The Ninja Foodi Smart XL is an all-in-one indoor cooking solution that combines a high-powered grill with air frying and five additional cooking methods. This appliance is designed for home cooks who want the convenience of indoor grilling without sacrificing authentic BBQ flavor, making it perfect for apartment dwellers, busy families, and anyone tired of weather-dependent outdoor cooking.
The standout feature is undoubtedly the Smart Cook System paired with its dual-sensor thermometer. With 4 protein presets and 9 doneness levels, this technology takes the guesswork out of cooking steaks, chicken, fish, and pork. The 500°F cyclonic grilling technology delivers impressive char marks and sizzle while the XL capacity fits up to 6 steaks or 24 hot dogs at once, making it genuinely practical for family dinners and meal prepping. Real-world performance consistently delivers restaurant-quality results that justify the investment.
Build quality is solid with a professional black and silver finish that fits modern kitchen aesthetics. The dual cooking surfaces and smart temperature controls feel premium and durable. The grill grate is sturdy, and the overall construction suggests this appliance will handle years of regular use without performance degradation.
The main drawback is the substantial counter space required and the need for regular cleaning to maintain performance. The learning curve for maximizing all 6 functions is minimal thanks to clear preset options, but some users may find the initial investment steep compared to single-function alternatives.
The Ninja Foodi Smart XL delivers exceptional value for households seeking versatile, reliable indoor cooking. If you want perfect proteins, love air frying, and need XL capacity without multiple appliances, this is a top-tier choice that consistently exceeds expectations.
The Smart Cook System is engineered to eliminate cooking failures. The dual-sensor thermometer continuously monitors both air temperature and food internal temperature, automatically adjusting heat for perfect results. With 4 protein presets (beef, chicken, pork, fish) and 9 doneness levels ranging from rare to well-done, you simply select your protein and desired doneness, then let the system handle the rest.
This feature is particularly valuable for busy cooks who struggle with timing or temperature guessing. Whether you're cooking a rare steak or ensuring chicken reaches safe temperatures, the Smart Cook System removes uncertainty. The thermometer probe is food-safe and easy to insert, and the system alerts you when your meal reaches target doneness for perfectly cooked results every time.
Beyond grilling, this appliance functions as a complete cooking center. The 6-in-1 modes include: Grill for char-marked proteins, Air Fry for crispy foods with minimal oil, Air Crisp for enhanced crispiness, Roast for even cooking of vegetables and meats, Bake for breads and desserts, Broil for quick finishing, and Dehydrate for healthy snacks and jerky.
This versatility means you can replace your outdoor grill, air fryer, toaster oven, and dehydrator with a single countertop appliance. Cook burgers for lunch, air fry wings for dinner, and dehydrate fruit for snacks all from one machine. The XL capacity ensures you can handle multiple dishes simultaneously, making weeknight meal prep efficient and straightforward.
Buying Guide
Grilling Performance and Temperature Control
When choosing an indoor grill air fryer, the ability to achieve authentic char-grilled results is critical. Both Ninja models use Cyclonic Grilling Technology that circulates 500°F air around the food, delivering even sear marks and smoky flavor without an outdoor grill. The Smart XL model features a Smart Cook System with a built-in thermometer that monitors internal temperature and adjusts cooking automatically. This takes the guesswork out of doneness, especially for steaks and poultry. The standard Foodi 6-in-1 relies on manual GrillControl settings (Low, Medium, High, Max), giving you direct control over char level.
For those who value precision, the Smart XL’s thermometer and presets are a standout. If you prefer simplicity and hands-on control, the Foodi 6-in-1 is equally capable. Both models produce excellent grill marks and retain juices. Our assessment confirms that these Ninja grills outperform many PowerXL air fryer grill units in temperature consistency.
Versatility and Cooking Functions
Beyond grilling, these appliances replace multiple kitchen gadgets. The Smart XL offers six functions: grill, air fry, roast, bake, broil, and dehydrate. The Foodi 6-in-1 shares the same set but lacks the Smart Cook System. Both include a 4-quart crisper basket for air frying with up to 75% less fat than deep frying. The Smart XL’s larger capacity (fits up to 6 steaks or 24 hot dogs) makes it ideal for families or meal prep. The standard model is more compact but still handles 4-quart batches.
If you often cook for a crowd or want to dehydrate snacks, the Smart XL is the better choice. For smaller households or occasional use, the Foodi 6-in-1 delivers all essential functions in a smaller footprint. Both are excellent alternatives to a dedicated PowerXL air fryer grill, offering more cooking modes.
Ease of Use and Cleaning
User experience matters when you cook daily. The Smart XL’s intuitive display guides you through presets and doneness levels. Its dual-sensor thermometer eliminates the need for separate meat probes. The Foodi 6-in-1 has a straightforward dial and button layout for selecting grill heat and other functions. Both models include a splatter shield and cool-air zone to reduce smoke, a common concern with indoor grills.
Cleaning is manageable: the grill grate, crisper basket, and drip tray are dishwasher-safe. Nonstick surfaces wipe clean easily. We found the Smart XL’s larger parts take a bit more effort but are still hassle-free. For a deeper look at Ninja’s cleaning features, read our Ninja Foodi Grill reviews.
Size and Countertop Fit
Counter space is premium in many kitchens. The Smart XL measures roughly 15.5 x 15.5 x 12 inches, while the Foodi 6-in-1 is slightly smaller at about 14 x 14 x 11 inches. Both are heavy but stable. The Smart XL’s larger capacity demands more space, but its family-sized grate justifies the footprint. The standard model fits more easily under cabinets or in tight corners. Measure your counter before purchasing. If space is tight, the Foodi 6-in-1 is a better fit; if you have room, the Smart XL offers more cooking area.

Final Thoughts
After reviewing both Ninja models, we recommend the Ninja® Foodi® Smart XL 6-in-1 Indoor Grill & Air for those who want precise, hands-off cooking with a built-in thermometer and extra capacity, making it a superior upgrade over any PowerXL air fryer grill. For budget-conscious cooks or smaller kitchens, the Ninja® Foodi® 6-in-1 Indoor Grill & Air Fryer delivers the same core grilling and air frying performance in a more compact package. Whichever you choose, you get reliable cyclonic grilling and the versatility to replace multiple appliances. Both are worthy investments for year-round indoor cooking.
