The Ninja Flip Toaster Oven and Air Fryer (model SP151) is a countertop oven that tips up on its back edge when you are done cooking, so it takes roughly half the counter space in storage mode. Reviewers broadly agree on the trade: strong air frying, pizza and wings for its size, in return for a shallow cooking cavity, a hot exterior and a back panel that does not open for deep cleaning. It suits small kitchens and households of two to four. It is a poor fit if you want to roast a whole chicken or replace a full-size oven.

Ninja Flip SP151 at a Glance
Ninja® Flip Toaster Oven & Air Fryer, Large Capacity, Stainless, SP151 | Stores Upright to Free Counter Space, Family Meals for Four in About 20 Minutes, Uses Less Power than a Standard Oven
As an Amazon Associate we earn from qualifying purchases. Product prices and availability are accurate as of the date/time indicated.
The listing is the stainless SP151. Retailers also sell other Flip-branded variants with different function counts (reviews mention 9-in-1 and 10-in-1 versions, one with an added broil rack), so confirm the model code SP151 before you order and do not assume a feature from another variant carries over.
- Best for: apartments, dorms, small families, anyone whose toaster oven lives on the counter and gets in the way.
- Skip if: you cook whole birds, tall roasts or 9×13 casseroles often, or need a cavity with a removable back panel for deep cleaning.
- Standout feature: flip-up-and-away storage, with quick preheat and a convection fan that does real air frying.
- Main weakness: low interior height and a very hot housing while it runs.

Unknown is better than guessed here: the listing title mentions only the flip storage, family meals for four in about 20 minutes and lower power use than a standard oven. Everything else above comes from published reviews, and the dimensions in particular vary between sources.
What the Flip Design Actually Gets You
The hinge is the reason this oven exists. Many toaster ovens end up either permanently on the counter, eating a wide strip of space, or in a cabinet, where they never get used. The SP151 sits flat for cooking and tips onto its back edge afterward. Reviewers put the saving at around 50 percent of the footprint, which is also the figure the maker uses. In a galley kitchen that is the difference between keeping the oven out and putting it away.
Two practical points are easy to miss. First, it has to be completely cool before you flip it, and the crumb tray must be emptied and the interior wiped, because loose crumbs and grease travel when the unit is tilted. One owner review described grease leaking from the rear feet after the oven was flipped into its storage position, which is a good reason to clear the pan and tray first. Second, the stored position needs a stable spot against the wall with room above, so measure the height of the flipped unit against any wall cabinet, not only its cooking footprint.
Cooking Performance: What Reviewers Report
Air frying and wings
This is the strength. The unit has six heating elements and a fan, and reviews describe crisp fries, wings finished in roughly 20 minutes, and little need to shake the basket as long as food sits in a single layer. Plan on batches: the 4 lb ceiling in the listing is a weight claim, not an invitation to heap food into the basket. Crowding is the main reason air-fried food turns out soft, in this or any air fryer oven.
Pizza and flat foods
The 12 inch pizza capacity is a headline use. Published scoring puts pizza ahead of every other mode, which fits the geometry: wide, shallow, close to the elements. Frozen pizza, flatbreads, sheet-pan vegetables, fish fillets and reheated leftovers are the sweet spot. A 13 inch pizza will not fit, which is where the older SP101 (covered below) pulls ahead.
Toast and bagels
Reviewers disagree. One described very consistent toast; another found it a little too brown and uneven, and a summary of retailer reviews also mentions unevenness. If toast quality is your top priority, a dedicated slot toaster still wins; if you make a few slices a week and prefer one machine, the SP151 is acceptable. Rotate the bread if you see edge browning, and expect to experiment for the first few uses.
Roasting and baking
The cavity is the limit. One review put the usable height at roughly 3 inches, and another noted it is about 4 inches shorter than previous Flip models, so a whole chicken, a thick pork roast or a tall casserole dish will not fit. Chicken pieces, thighs, sausages, small trays of cookies and quick bakes work well. Dehydrating is listed as a mode, but with a small cavity it is a small-batch feature, not a replacement for a dedicated dehydrator.
Who Should Buy the Ninja Flip, and Who Should Skip It
Good fit:
- One- to four-person households that mostly cook flat or small foods.
- Renters and dorm residents who need the counter back after each meal. See our compact air fryer toaster ovens for dorm rooms for other small options.
- People who currently heat a full oven for a 20-minute job and want to keep the kitchen cooler.
Better to skip:
- Families who want to cook a whole chicken or a holiday roast in the unit.
- Anyone who wants an interior they can fully reach for deep cleaning, since the back panel does not open on this model.
- Cooks who would run it under low cabinets with no clearance.
If you are still deciding between an air fryer, a convection toaster oven and a combo, our guide on convection toaster oven vs air fryer combo walks through the differences in cavity shape, noise and cleaning.
Daily Use, Cleaning and Safety
Expect a faint burn-off smell on the first cycle, which several reviews mention; run it empty with the door closed and a window open. The cavity is not described as nonstick, so grease bakes on if you let it. A practical routine is to line the sheet pan with foil or a pan liner for greasy foods (our oven liner guide compares the types), empty the crumb tray after every few uses, and wipe the cavity once it is warm but not hot. Do not line the bottom of the cavity or cover the elements, which can block airflow and create a fire risk.
Heat is the safety topic that reviews raise most. The housing gets very hot during use, and one review reports surface temperatures above 350 degrees F. Keep the oven away from cabinets, curtains, paper towel racks and plastic containers; leave the clearance the manual specifies; use oven mitts to pull the rack; and do not leave children or pets alone near it. Because the unit flips, never tilt it while any part is warm.
Noise is moderate: the fan is audible in air fry mode, like most countertop air fryers, and one buyer felt a replacement unit was louder than the first. Reliability reports are mixed; one buyer said it failed sooner than expected, so keep the receipt and check the warranty terms on the listing.
Pros and Cons
- Pros: flip-up storage that reclaims counter space; fast preheat; credible air frying and pizza; simple knob-style controls; includes rack, pan, basket and crumb tray; modest power draw for short jobs.
- Cons: shallow cavity; back panel does not open; hot exterior; toast quality varies; cleaning the basket and corners takes effort; not suited to large roasts.

The SP101 is the bigger sibling in the same flip family. Per published comparisons it fits a 13 inch pizza and up to nine slices of toast, includes a 13 by 13 inch sheet pan, and has a removable back panel that makes deep cleaning easier. The SP151 uses a different heating approach (OvenCrisp) and one comparison gave it a slight edge in crispness, but if cleaning and size matter more than the last bit of crunch, the SP101 deserves the extra counter space.

Buying Checklist
- Measure the flipped height against your wall cabinet, with room behind.
- List what you cook most. If it is pizza, wings, fries and reheats, the SP151 fits. If it is whole poultry or casseroles, look at a taller French-door model.
- Decide how much deep cleaning you will do. If you want access to the back, choose the SP101.
- Confirm the model code SP151 and variant on the listing.
- Plan where cords and heat will go, away from walls and curtains.
FAQ
Does the Ninja Flip really air fry, or is it just a convection oven?
It does both. The six heating elements and fan run in air fry mode to circulate hot air around food, and reviews report crisp fries and wings. Results depend on cooking in a single layer.
Can you cook a whole chicken in it?
Generally no. Reviews describe the interior as low, around 3 inches in one account, so a whole bird will not fit. Chicken pieces, thighs and breasts do fit. The larger Ninja Foodi XL Pro lists room for a 5 lb chicken.
How much counter space does it save?
Reviewers and the maker cite about half the footprint when it is flipped up. Measure height against cabinets, since the flipped unit is taller than it is deep.
Is it hard to clean?
Reviews are mixed. The back panel does not open and the cavity is not described as nonstick, so grease bakes on if left. Foil on the pan and regular wiping make it manageable.
What is the difference between the SP151 and SP101?
The SP101 is larger, fits a 13 inch pizza and nine slices, and has a removable back panel. The SP151 is more compact and uses OvenCrisp heating.
Is the outside hot?
Yes. Multiple reviewers say the housing gets very hot, and one reports above 350 degrees F. Keep it clear of cabinets and flammable items and use mitts.
Does it replace a regular oven?
For small meals, yes. For big roasts, multiple trays or tall dishes, no. A full oven is still needed for those.
How long is the warranty?
One review lists a two-year limited warranty. Check the current listing, since terms can differ between variants.
Which One Should You Buy?
- Tight kitchen, flat foods: the Ninja Flip SP151.
- Want easier cleaning and a bigger pizza: the Ninja SP101.
- Need height for chickens or casseroles: Ninja FO101 or Foodi XL Pro.
- Want a classic oven shape at a fair cost: Cuisinart TOA-70NAS.
- Baker who wants precision: Breville BOV860.
- Cheapest way into a combo: Gourmia 6-slice.
