Breville Smart Oven Air Fryer Pro vs Ninja Flip: Which Toaster Oven Fits Your Kitchen?
Short answer: The Breville, if you have the counter for it: it holds a 9 × 13 pan and makes better toast. Pick the Ninja Flip if counter space is tight, since it folds up against the wall.
Breville Smart Oven Air Fryer Pro
4.5★ · 13,204 ratings
- You want to bake casseroles or roast a chicken in it
- You make toast for three or four people at a time
- You have a 22-inch stretch of counter to give up for good
Ninja Flip SP151
4.3★ · 2,192 ratings
- Your counter is small or shared with a coffee setup
- You mostly air fry, reheat and make sheet-pan dinners
- You want the faster preheat for weeknight dinners
Picture your counter before you pick. The Breville is 21.5 inches wide and sits there permanently. The Ninja Flip is 15.75 inches wide, and when dinner’s done you tip it up on its back so it takes roughly half that footprint. Everything else follows from that difference.

| Functions | 13 | 8 |
| Interior height (ShouldIt) | 8.0 in | 5.9 in |
| Biggest pizza | 13 in | 12 in |
The deciding difference: height
Both run at 1800 W, and both air fry, bake, broil and toast. The cavity is where they split. ShouldIt measured the Breville’s interior at 16.5 × 12.5 × 8 inches. The Ninja measured 13.6 × 12.2 × 5.9. Those two extra inches decide whether a whole chicken, a Dutch oven or a tall loaf goes in at all. If those foods matter to you, the choice is made.
If they don’t, the Ninja’s short, wide box is a strength. Its automatic preheat finished in about a minute and a half in ShouldIt’s run, while the Breville’s took roughly 5 minutes (to a somewhat higher temperature, so it’s not a perfect comparison).
Where they differ
Toast. The Breville wins clearly. ShouldIt got evenly golden tops on four slices, and the second round shortened itself to 4 minutes 10 seconds and matched. The Ninja’s toast was paler and patchier at level 4. A repeat batch on the same timer came out too dark.
Air frying. Both use quartz elements and convection, and both scored 9.8 for pizza in ShouldIt’s runs. For wings and fries, neither matches a basket air fryer with the fan right overhead.
Cleaning. Grease on quartz elements is a chore on both. ShouldIt also noted the Ninja’s chamber walls aren’t nonstick, so splatter builds up.
Doors. The Breville has a drop-down door. The Ninja’s swings to the side and can slam if you don’t close it by the handle.
What owners say
Breville owners rave about results: 87% of 2,624 performance mentions are positive, and 96% of versatility mentions. Durability is the dark spot. 293 of 416 durability mentions are negative, often a failed element or cracked glass. Value is split too, at 64% positive.
Ninja owners are happiest about the design. 84% of flip-up mentions and 90% of space-saving mentions are positive. The most common letdown is size: 40 of 110 size mentions say the tray or basket is smaller than they expected. Durability isn’t among its top topics yet, but at 2,192 ratings it also has far less history than the Breville.
Bottom line
If counter space is no issue, the Breville is the better oven. It’s taller and toasts more evenly, and it handles real baking. Just register the 2-year warranty, because the element and glass complaints are real. If your kitchen is tight, the Ninja Flip gives up height and toast quality to disappear when you’re done, and for many apartments that’s the right trade.

FAQ
Is the Ninja Flip big enough for a family of four?
For flat foods, yes. Ninja says it fits six chicken breasts or 4 pounds of food, and ShouldIt rated it for a family of four. The 5.9-inch interior height is the limit, not the floor space.
Can the Breville Smart Oven Air Fryer Pro replace a regular oven?
For a small household, mostly yes. It fits most 9 × 13 pans, a 12-cup muffin tray and, by Breville's count, a 14-pound turkey. A large holiday meal still needs the full-size oven.
Which one makes better toast?
The Breville. ShouldIt scored its toast 9.0 against 7.6 for the Ninja, and its toast mode shortens the second batch on its own. On the Ninja you lower the shade yourself for back-to-back rounds.
