What Is the Ninja Air Fryer Toaster Oven Combo?
The Ninja Air Fryer Toaster Oven Combo (Model SP151) is a multifunctional countertop oven designed to consolidate multiple cooking appliances into a single footprint. It combines high-speed air convection with direct infrared heating to bake, roast, broil, toast, and air fry foods with minimal preheat delay. Instead of sitting idle and taking up valuable workspace when not in use, the entire oven folds vertically against your kitchen wall or backsplash.
Engineered primarily for fast daily cooking, the SP151 holds a full 12-inch pizza or six slices of bread on its wide 13×13-inch cooking surface. It targets apartments, RVs, small kitchens, and busy families who need to prepare quick meals without turning on a large main oven.
Who Should Buy It?
Best For
- Cooks with small kitchen counters who need a flip-away storage design.
- Busy households needing meal prep completed up to 50% faster than standard ovens.
- Anyone seeking crispy, lower-fat meals using minimal cooking oil.
Skip If
- You regularly roast tall, whole 5 to 6 pound chickens or deep casseroles.
- You prefer traditional deep frying textures over air-circulated crispness.
Key Feature Breakdowns
Compact Flip-Up Storage Design
The standout feature of the Ninja SP151 is its vertical storage orientation. Once the unit cools down, you can lift the entire front handle to pivot the oven upward against your wall. This action frees up 50% of your usable counter area. The soft-drop mechanism ensures controlled movement, while the back panel opens easily for thorough cleaning access inside the bottom cavity.
OvenCrisp Technology and Infrared Heating
Unlike basic toaster ovens that rely solely on top and bottom thermal coils, the SP151 integrates OvenCrisp Technology. This system combines six distinct infrared heating elements with high-velocity air circulation. The infrared warmth penetrates food quickly while superheated air crisps the exterior, yielding moist interiors and crunchy crusts without requiring long preheating cycles.
8-in-1 Cooking Versatility
The intuitive digital control panel provides access to eight preset cooking programs: Air Fry, Air Roast, Air Broil, Bake, Toast, Bagel, Dehydrate, and Keep Warm. The precision thermal control operates across a broad 85°F to 450°F temperature range, allowing you to gently dehydrate fruit snacks at low temperatures or blast frozen pizza crusts with high heat.
Healthier Cooking with Less Oil
Air frying in the Ninja SP151 allows you to recreate popular fried favorites with significantly less added fat. Rapid convection forces hot air around food inside the included mesh air fry basket, crisping french fries, chicken tenders, and vegetables with up to 75% less oil compared to deep frying.
Before You Buy: Measure the clearance under your upper kitchen cabinets before purchase. While the unit sits low during cooking, flipping it upright requires 14 inches of vertical overhead clearance from your countertop.
Pro Tip: When air frying fatty items like bacon or chicken wings, place the sheet pan on the bottom wire rack underneath the air fry basket. This catches drippings, prevents smoking, and keeps cleaning hassle-free.
How It Performs in Real Use
For Weeknight Dinners
Because the SP151 preheats in approximately 60 seconds, weeknight meals come together rapidly. A tray of salmon fillets with roasted asparagus cooks in under 12 minutes. The wide 13×13-inch sheet pan allows you to lay out ingredients in a single flat layer without stacking, ensuring even browning across all items.
For Toasting and Baking
The toaster function offers adjustable shade settings from light to dark. Toasting six slices of sandwich bread simultaneously yields consistent edge-to-edge browning without dry spots. Baking flat breads, cookies, and 12-inch frozen pizzas delivers crisp lower crusts thanks to the direct lower infrared heating elements.
For Reheating Leftovers
Reheating leftover pizza, fried chicken, or roasted vegetables in the SP151 restores original crispiness far better than a microwave. The Air Roast function heats food thoroughly inside without turning crusts soggy or dry.
Setup and Usage Tips for Best Results
- Level Placement: Place the unit on a flat, heat-resistant surface with 2 to 3 inches of rear clearance for proper hot air venting.
- Single Layer Cooking: Avoid crowding the air fry basket. Keeping food items in a single layer yields maximum crispiness.
- Crumb Tray Maintenance: Empty the removable crumb tray after every few uses to prevent oil buildup and burn odors.
- Flipping Safety: Allow the oven to cool completely for 10 to 15 minutes before flipping the unit upright into its storage position.

Is It Worth the Price?
The Ninja SP151 delivers strong long-term value for households seeking convenience and space efficiency. By combining an air fryer, toaster, broiler, and convection oven into one machine, it eliminates the need to purchase separate single-purpose countertop units.
While premium full-sized countertop ovens cost significantly more and take up permanent counter space, the SP151 provides high-end infrared heating performance in a space-saving chassis. For small kitchen owners and busy cooks who prepare sheet pan meals, fries, toasts, and snacks daily, it represents a smart investment.
How It Compares to Alternatives
Compared to traditional basket-style air fryers, the Ninja SP151 offers a much wider cooking surface area. Basket air fryers require stacking food in layers, which often leads to uneven cooking. The SP151 spreads food out on a flat 13×13-inch sheet pan, ensuring uniform heat contact.
Compared to larger countertop toaster ovens, the Ninja SP151 has a lower vertical clearance, meaning you cannot roast a tall 6-pound chicken. However, full-sized toaster ovens sit permanently on your counter, whereas the SP151 flips away in seconds to give you back your prep area.
Frequently Asked Questions
Can I use aluminum foil in the Ninja Air Fryer Toaster Oven?
Yes, you can use aluminum foil on the sheet pan or wire rack to make cleanup easier. Always ensure the foil is secured tightly to the pan and does not touch the heating elements or block interior airflow.
Is the Ninja Air Fryer Toaster Oven easy to clean?
Yes, cleaning is straightforward. The crumb tray slides out from the bottom for quick debris removal, and the rear panel opens when flipped up, giving you direct physical access to wipe down the inner cooking chamber.
What is the warranty period for this appliance?
The Ninja Air Fryer Toaster Oven Combo comes with a one-year limited warranty from the manufacturer, covering defects in materials and workmanship under normal household use.
Does it have a built-in timer feature?
Yes, the digital display includes built-in countdown timers tailored to each cooking preset. The oven automatically shuts off when the cooking timer reaches zero.
Can I cook frozen food directly in it?
Yes, you can cook frozen foods such as pizzas, chicken tenders, french fries, and snacks directly without thawing. The combination of infrared heat and air convection cooks frozen foods quickly and evenly.
How much counter space does the flip-up feature save?
Flipping the oven vertically against your backsplash reclaims up to 50% of its counter footprint, allowing you to use that space for meal prep or other tasks when you are finished cooking.
The Bottom Line
The Ninja Air Fryer Toaster Oven Combo (Model SP151) is an exceptionally practical multi-cooker that solves kitchen clutter without sacrificing cooking performance. Its 60-second preheat, 8-in-1 functions, and rapid crisping make it a top choice for fast daily meals. If you want high-speed air frying and baking in a space-saving design, this unit is well worth buying.
