The Ninja Combi All-in-One Multicooker promises to replace your oven, air fryer, slow cooker, and more — all while getting dinner on the table in as little as 15 minutes. That’s a bold claim for any single appliance, and bold claims deserve honest scrutiny. After digging through hundreds of owner experiences, comparing the Combi against competing multi-cookers, and stress-testing its feature set against real-world cooking scenarios, we’ve distilled everything into a clear framework: five genuine strengths and three legitimate weaknesses. Whether you’re a meal-prep warrior, a busy parent, or someone who simply wants fewer gadgets cluttering the counter, this breakdown will help you decide if the Ninja Combi earns its spot in your kitchen.
Best for: Busy households that want one appliance to handle weeknight dinners from start to finish
What Is the Ninja Combi, Exactly?
Before we get into the numbered breakdown, let’s set the stage. The Ninja Combi (model SFP701) is a countertop appliance that merges rapid cooking technologies — steam, convection, and air frying — into a single unit. Ninja markets it as a 14-in-1 cooker, and the function list includes air fry, bake, roast, broil, steam, sauté, slow cook, proof dough, dehydrate, and several “Combi” modes that layer steam and convection simultaneously. The Combi modes are the headline feature: by injecting steam while circulating hot air, the appliance can cook proteins and sides together in dramatically less time than a conventional oven.
If you’ve been exploring the broader world of countertop combo cookers — like the Dreo ChefMaker and its accessories or even full-size French-door air fryer ovens — the Ninja Combi sits in a unique middle ground: more versatile than a dedicated air fryer, more compact than a wall oven, and more technologically ambitious than a standard Instant Pot.
The Full Review: Ninja Combi All-in-One Multicooker, Oven, & Air Fryer
The Ninja Combi is the kind of appliance that either becomes the centerpiece of your kitchen workflow or ends up gathering dust — there’s very little middle ground. After extensive research, we believe it leans heavily toward the former for the right buyer. Below, we break down exactly why.
Strength #1: Genuinely Fast Complete Meals
Ninja’s “complete meals in 15 minutes” tagline sounds like marketing fluff, but owners consistently confirm it’s surprisingly accurate for many recipes. The Combi modes layer steam with convection heat, which means a chicken breast and roasted vegetables can cook simultaneously on different rack levels and finish at roughly the same time. One Amazon reviewer put it bluntly: “I was skeptical about the 15-minute claim, but I’ve made chicken thighs with broccoli and rice in under 20 minutes including prep. This thing is not messing around.” The speed comes from the steam injection, which transfers heat far more efficiently than dry air alone. For weeknight dinners when you walk in the door exhausted, this is a genuine game-changer.
Strength #2: Impressive Air Frying Performance
Many multi-function appliances treat air frying as an afterthought — a checkbox feature that produces soggy, disappointing results. The Ninja Combi bucks that trend. Its convection system circulates air aggressively enough to produce crispy fries, crunchy chicken wings, and golden-brown fish fillets that rival dedicated air fryers. The cooking chamber is also larger than most basket-style air fryers, so you can cook in a single layer without overcrowding. If air frying is a priority for you, the Combi delivers.
Strength #3: The Combi Steam Modes Are a Real Innovation
This is where the Ninja Combi separates itself from the pack. The ability to combine steam and dry heat isn’t just a speed trick — it fundamentally changes cooking outcomes. Bread comes out with a bakery-quality crust. Chicken stays juicy inside while the skin crisps. Reheated leftovers taste freshly cooked instead of dried out. The steam modes are the single biggest reason to choose this appliance over a conventional air fryer or toaster oven. They represent a genuine leap in countertop cooking technology.
Strength #4: 14 Functions That Actually Work
Plenty of appliances boast double-digit function counts where half the modes are redundant or poorly implemented. The Ninja Combi’s 14 functions are, for the most part, legitimately useful. Slow cooking works well for stews and chili. The sauté function lets you brown meat directly in the pot before switching to a different mode — no extra pan required. Proofing dough at a controlled temperature is a nice touch for home bakers. Dehydrating jerky or fruit works, though it’s slower than a dedicated dehydrator. The point is: these aren’t phantom features. Most of them deliver real cooking value.
Strength #5: Thoughtful Design and Build Quality
The Ninja Combi feels well-built. The control panel is intuitive, the cooking pot is non-stick and easy to clean, and the included accessories (crisper tray, rack) are sturdy. The lid locks securely during steam modes, and the water reservoir for the steam function is easy to fill and remove. Ninja clearly spent time on the user experience, and it shows. Owners frequently praise how quickly they were able to start cooking without needing to study the manual extensively.
Weakness #1: It’s Big — Really Big
Let’s not sugarcoat this: the Ninja Combi is a substantial countertop appliance. It’s taller and deeper than most air fryers, and it demands dedicated counter real estate. If you have a small kitchen or limited counter space, this is a serious consideration. Some owners report needing to rearrange their entire counter layout or store the unit in a cabinet between uses — which, given its weight, isn’t exactly convenient. Before purchasing, measure your available space carefully. This is not a tuck-it-in-a-corner appliance.
Weakness #2: The Learning Curve Is Real
Despite the intuitive controls, mastering the Combi modes takes experimentation. The included recipe book helps, but once you venture beyond those specific recipes, you’re in trial-and-error territory. How much water to add for steam? Which rack position for which food? When to use Combi Steam vs. Combi Crisp? These questions don’t have obvious answers, and getting them wrong can mean soggy food or unevenly cooked meals. As one reviewer noted: “Love this thing, but my first three attempts were mediocre. Once I figured out the water levels and rack positions, it became amazing. Give yourself a week to learn it.” If you want plug-and-play simplicity, be prepared for a short adjustment period.
Weakness #3: Steam Means Moisture Management
The steam function is the Combi’s superpower, but it comes with a practical trade-off: moisture. After steam-heavy cooking sessions, the interior and lid accumulate condensation that needs to be wiped down. The water reservoir needs to be emptied and dried to prevent mineral buildup. And if you’re not careful when opening the lid after a steam cycle, you’ll get a face full of hot vapor. None of these issues are deal-breakers, but they add maintenance steps that a conventional air fryer or oven doesn’t require. Owners in humid climates have also noted that the extra moisture can make the kitchen feel steamier than expected.
Who Should Buy the Ninja Combi?
The ideal buyer is someone who cooks dinner most nights, values speed, and wants to consolidate multiple appliances into one. Families with kids, busy professionals, and anyone tired of juggling an air fryer, slow cooker, and oven will find genuine value here. It’s also excellent for anyone curious about steam-assisted cooking but not ready to invest in a full-size steam oven.
Who Should Skip It?
If you have very limited counter space, prefer dead-simple appliances with no learning curve, or primarily cook for one person (the capacity may be overkill), you might be better served by a dedicated air fryer or a simpler multi-cooker. Ninja’s own lineup includes smaller, less complex options that may suit solo cooks better. And if you already own a quality countertop oven-air fryer combo, the Combi’s main advantage — steam — may not justify the upgrade unless you’re specifically excited about that feature.
The Bottom Line
The Ninja Combi All-in-One Multicooker is one of the most genuinely innovative countertop appliances to emerge in recent years. Its five strengths — speed, air frying quality, steam innovation, functional versatility, and build quality — are substantial and well-earned. Its three weaknesses — size, learning curve, and moisture management — are real but manageable for most buyers. This is not a perfect appliance, but it’s a very good one that delivers on its core promise: fast, complete, flavorful meals from a single device.

Frequently Asked Questions
Can the Ninja Combi replace my oven?
For most everyday cooking — roasting chicken, baking casseroles, making sheet-pan dinners — yes, it can handle the job. However, it can’t accommodate a full-size turkey or large baking sheets, so you’ll still want access to a conventional oven for holidays and large-batch cooking.
Is the Ninja Combi dishwasher safe?
The cooking pot, crisper tray, and rack are all dishwasher safe, which makes cleanup significantly easier. The base unit and lid should be wiped down by hand.
How loud is the Ninja Combi?
The fan noise during air frying and convection modes is comparable to other countertop air fryers — noticeable but not disruptive. Steam modes are quieter. You can comfortably hold a conversation in the same room.
Does it work well for meal prep?
Absolutely. The combination of speed and capacity makes it excellent for batch-cooking proteins, grains, and vegetables. Many owners report using it specifically for Sunday meal prep sessions. If you’re a fan of Ninja’s kitchen ecosystem, you might also enjoy reading about long-term ownership of the Ninja CREAMi for another perspective on living with Ninja appliances day to day.
How does the Combi compare to an Instant Pot?
The Instant Pot is primarily a pressure cooker with some additional functions. The Ninja Combi does not pressure cook — its speed comes from steam-convection technology instead. The Combi excels at crispy, roasted, and baked foods where the Instant Pot falls short, but the Instant Pot is better for soups, beans, and traditional pressure-cooking tasks.
