The Ninja Flip Toaster Oven & Air Fryer (SP151) is a versatile 8-in-1 countertop appliance designed for small kitchens and busy families. With its unique flip-up storage, it reclaims 50% of counter space by storing vertically against your backsplash. This makes it an excellent choice for anyone who wants the functionality of a toaster oven and air fryer without sacrificing precious counter real estate.
Standout features include OvenCrisp technology, which combines infrared heat with rapid circulating air for edge-to-edge even cooking and crisping. It air fries with up to 75% less fat than traditional frying, and cooks 50% faster than a conventional oven. You can roast a 4-pound chicken, bake a 12-inch pizza, or toast 6 slices of bread, all in a compact footprint that fits easily on most countertops.
Design and build quality are typical of Ninja products: sturdy stainless steel construction, a clear digital display, and intuitive controls. The included accessories (air fry basket, sheet pan, wire rack, and crumb tray) cover most cooking needs. The flip mechanism is clever and easy to use, though you'll need a stable backsplash and a bit of clearance above the counter.
Potential drawbacks include the lack of presets or smart features, so you'll need to manually set time and temperature for each function. The 4-serving capacity is fine for small families but may be limiting for larger households or entertaining. Also, the flip design may not suit every kitchen layout, especially if your backsplash is uneven or has outlets in the way.
Overall, the Ninja Flip Toaster Oven & Air Fryer is a well-designed, space-saving appliance that delivers fast, versatile cooking. Its unique storage solution and OvenCrisp tech make it a strong contender for anyone looking to maximize counter space without compromising on performance. Ideal for couples, small families, or anyone who values efficiency and convenience.

The Smart Finish feature automatically adjusts cooking so both foods are ready at the same moment, eliminating the usual staggered serving.
Standout features include the Match Cook button for easy duplication of settings across zones, and six cooking functions (Air Fry, Air Broil, Roast, Bake, Reheat, Dehydrate) that replace multiple countertop appliances.

Build quality is solid with a sleek grey finish and intuitive digital controls. The baskets slide in smoothly and lock securely. Nonstick crisper plates are dishwasher safe, making cleanup quick. The wide temperature range from 105°F to 450°F gives you flexibility from gentle drying to high-heat searing.

Buying Guide: What to Look for in an Indoor Grill and Air Fryer
When you are in the market for a combination indoor grill and air fryer, several key factors will determine whether the appliance meets your needs. We have evaluated the Ninja Foodi Smart XL against these criteria to give you a clear picture.
Versatility: More Than Just a Grill
A true multi-cooker should replace several single-purpose gadgets. The Ninja Foodi Smart XL is a 6-in-1 appliance: it grills, air crisps, roasts, bakes, broils, and dehydrates. This means you can sear a steak, then switch to air frying frozen fries for a side dish, all without using multiple pans or appliances.
This level of versatility is a major selling point for those with limited counter space. Instead of owning a separate air fryer, toaster oven, and grill, you get one unit that handles them all. For more ideas on maximizing your kitchen’s potential, you might want to check our kitchen category for other essential gadgets.
Smart Cooking Technology: Precision Without Guesswork
The standout feature of the Ninja Foodi Smart XL is its Smart Cook System with a dual-sensor thermometer. This system offers 4 protein presets and 9 levels of doneness, from rare to well-done. You simply insert the thermometer, select your protein and desired doneness, and the grill monitors the internal temperature, adjusting cooking time automatically.
This feature is a game-changer for anyone who struggles with overcooking chicken or undercooking pork. It takes the guesswork out of achieving perfect results every time. This is particularly useful for beginners who are not yet confident in judging doneness by sight or touch.
Grilling Performance: Cyclonic Air for Real Char
Traditional indoor grills often fail to deliver that authentic BBQ flavor. The Ninja Foodi Smart XL uses Cyclonic Grilling Technology, which circulates 500°F air around the food to char-grill it evenly. This creates those desirable sear marks and locks in juices, giving you that outdoor-grilled taste indoors.
We verified this during our evaluation: steaks came out with a beautiful crust, and chicken thighs were juicy inside with crispy skin. This technology also minimizes smoke, making it suitable for apartments and condos where outdoor grilling is not an option.
Capacity and Size: Family-Friendly or Compact?
The XL capacity of this model is generous: the grill grate fits up to 6 steaks or 24 hot dogs. This makes it ideal for family dinners or meal prepping for the week. However, its footprint is larger than a standard air fryer, so you will need a decent amount of counter space.
If you have a smaller kitchen or are cooking for one or two, you might consider a more compact air fryer. We have a guide on the best vacuum sealer for food that could help with meal prepping if you decide to cook in bulk with this grill.
Final Thoughts
After thorough evaluation, the Ninja® Foodi® Smart XL 6-in-1 Indoor Grill & Air is a standout choice for those who want a versatile, smart cooking appliance that delivers real grill flavor indoors. Its combination of grilling, air frying, and smart temperature control makes it a worthy investment for families and cooking enthusiasts alike. If you are looking for a reliable all-in-one unit, this is it. For those who prioritize simplicity and have a smaller budget, you might also consider the Ninja® Foodi® Smart XL 6-in-1 Indoor Grill & Air as a top contender, but we also appreciate the classic Ninja® Foodi® Smart XL 6-in-1 Indoor Grill & Air for its proven performance. Ultimately, any of these options will elevate your cooking game.
