Is the Ninja Flip SP151 good for a family?
Yes, for weeknight dinners that fit on one or two sheet pans. Ninja describes it as feeding up to 4 people in as little as 20 minutes, which suits a small family.
It's a good fit for a family that uses the auto cook menu and changes racks often. The adjustable rack gives more choices than a fixed shelf does.
How does the auto cook menu work?
The auto cook menu sets the time and temperature for common foods, so you choose the food and the oven does the rest. That's quicker than setting each cook by hand.
Use the menu for your regular meals, then switch to manual settings when you want a different result. Check the food partway through the first few cooks until you know the timing.
Are the Ninja Flip SP151 buttons easy to learn?
Most of the settings sit on a clear button panel, so the layout is easy to read. The first week takes longer, since you learn which buttons give crisp food and which give a soft finish.
Is the Ninja SP151 good for weeknight meals?
Yes, for a dinner that fits on one or two pans. The auto cook menu gives a fast start, and the button panel makes the second cook as quick as the first.
Try a sheet pan of vegetables and a small chicken portion as a test dinner. It's a good way to learn the timing before you rely on the oven for a crowd.
What fits inside the SP151?
Ninja says the SP151 air fries or roasts up to 4 pounds of food, bakes a 12-inch pizza and toasts up to 6 slices of bread. It also fits 6 chicken breasts.
The rack adjusts, so you can set it for a tall food or a shallow pan. Move the rack before you turn the oven on, and check that it sits level.
How does the adjustable rack work in practice?
The rack moves to a different height, so a tall food can sit closer to the top heat or a shallow pan can sit lower. Move the rack before you turn the oven on, and check that it sits level before you load food.
Often, moving the rack fixes uneven browning faster than adding more time. If the top browns before the middle cooks, try one notch lower.
Always check the food with the rack in its new position, since the top and bottom can brown at different rates.
How much counter space does the flip design save?
Ninja says the SP151 takes up 50 percent less space when flipped up and away. That's useful on a crowded counter, where the oven can stand against the backsplash when it's stored.
The SP151 is about 17 inches deep, so it needs a bit less depth than the SP101. Measure the depth you need with the oven flipped up before you buy.
How does the side-swing door affect placement?
The door swings to the side, not down, so it needs open space on one side. Leave enough room to open it fully and to pull out a tray without bumping a wall or a cabinet.
Plan the spot before delivery day, since a door that can't open fully is easy to avoid with a quick measure.
Does the Ninja SP151 work for reheating?
Yes, the SP151 includes reheat among its settings, so you can bring back leftovers without a microwave. Cover the food with foil if the top browns before the middle warms.
Fries from the fridge reheat well in the air fry basket, though they'll be softer than fresh.
For leftover pizza, the air fry setting crisps the crust again. Check the center of the slice before you eat it.
What comes in the box?
The SP151 includes an air fry basket, a crumb tray, a sheet pan and a wire rack. Those are the pieces you need for the first cook.
Pull the crumb tray after each cook that drips or throws crumbs, and wash the racks and pans once they cool. Check the manual for the dishwasher rules.
How does the SP151 handle a family-size batch?
Ninja says the SP151 feeds up to 4 people in as little as 20 minutes, which suits a small family with one cook. It air fries or roasts up to 4 pounds of food at once, so a batch of wings or fries covers a few plates.
For a larger batch, cook in two rounds rather than crowding the basket. Crowded food steams instead of crisping, so two rounds usually turn out better than one overloaded batch.
What should you check before you buy?
Check the counter width, the depth with the oven flipped up and the side room for the door. Those three numbers decide most fit problems.
Ninja says the SP151 is 80 percent more energy efficient than a traditional full-size oven. Check the box or Ninja's site for the warranty term before you buy.
Can the SP151 dehydrate and bake?
The SP151 includes dehydrate and bake among its eight functions. Dehydrate suits fruit and herbs, and bake suits a 12-inch pizza or a small tray of cookies.
Its 85 to 450 F range covers both low and high settings, which helps when you dry food slowly. Check dehydrating food regularly, since the time depends on thickness and moisture.
How do the alternatives compare?
The SP101 is the closest sibling. It has knob controls, a pan that fits a 13-inch pizza and a deeper footprint.
The Foodi XL Pro is the larger choice for big meals, with two cooking levels, a bigger interior and the heaviest body in this group. The Ninja Foodi XL Pro review covers it in full.
Who should avoid the Ninja Flip SP151?
Skip it if you need a 13-inch pizza, since the SP151 bakes a 12-inch one. Skip it too if your counter has no room on one side for the door to swing open.
Households that cook for a large group every day may find the SP101 or the Foodi XL Pro a better match.
Is the Ninja Flip SP151 a good first combo oven?
It's a good first combo oven for a household that wants air fry, toast and bake in one countertop unit. The button panel and the auto cook menu make it easy for a new user to start.
The flip design helps a first-time buyer too, since the oven stores out of the way when you're not cooking. Measure the depth and the side room before you buy, so delivery day goes smoothly.
How do the scores compare?
Our score weighs specs, features and buyer feedback against what you're shopping for.
The SP151 scores 8.6 for its button panel, its adjustable rack and its wide temperature range. It loses a little for its side-swing door, which needs more clearance than a dropdown door.
Is the Ninja Flip SP151 worth buying?
It's worth buying if you want a flip-up oven with buttons, an auto cook menu and an adjustable rack. If you prefer knobs or need a 13-inch pizza, the SP101 is the better match.
