If you are stuck between the two multicooker heavyweights, here is the honest split. The Instant Pot Duo 7-in-1 (6-Quart) is the better pure pressure cooker — cheaper, simpler, lighter, and backed by the biggest recipe community and a decade as testers’ top pick. The Ninja Foodi 6.5-Quart Pressure Cooker & Air Fryer does one thing the Instant Pot can’t: its SmartLid also air-fries and crisps, so it replaces a pressure cooker and an air fryer in a single (bulkier, pricier) box. Buy the Instant Pot if you mainly want to pressure and slow cook and you value simplicity and price. Buy the Ninja Foodi if a crispy finish — or ditching a separate air fryer — matters to you. Neither one is a canner, and you should not can low-acid food in either.
The quick answer
Both machines cook the core jobs well, so the decision comes down to one question: do you want a crispy finish?
Choose the Instant Pot Duo 7-in-1 (6-Quart) if pressure and slow cooking is the point. It is the simplest, cheapest, and most-supported multicooker you can buy, it takes up less room, and it is the machine testing consensus has leaned on the longest. If you already own an air fryer — or never want one — the Instant Pot gives you everything a multicooker should without paying for hardware you won’t use.
Choose the Ninja Foodi 6.5-Quart Pressure Cooker & Air Fryer if you want one appliance that pressure cooks and air-fries. Its SmartLid lets you pressure cook a pot roast and then crisp the top, or steam and then SteamCrisp a tray of vegetables, without moving food to a second machine. You accept more size, a higher price, and extra parts in exchange for replacing two appliances with one.
Everything below explains exactly where those two paths diverge.
Head-to-head
| Instant Pot Duo | Ninja Foodi | |
|---|---|---|
| Core job | Pressure + slow cook, rice, steam, sauté | Same PLUS air-fry / SteamCrisp |
| Crisping / air-fry | No | Yes (SmartLid) |
| Size / weight | Lighter, smaller footprint | Bulkier, heavier, more parts |
| Recipe community | Enormous | Smaller but growing |
| Price | $$ (value) | $$$ |
| Canning low-acid food | No (unsafe) | No (unsafe) |
The table gives the short version; a few rows hide a real decision.
Core job. Both handle the multicooker basics — pressure cook, slow cook, steam, sauté, and rice — and both do them well. Beans, stews, tough cuts, stock, and risotto all come out faster than they would on the stovetop; Instant Pot markets speeds up to 70% faster than conventional methods, a manufacturer figure rather than something we measured. On these shared jobs, it’s close to a wash.
Crisping. This is the one row that decides most purchases. The Instant Pot Duo does not brown or crisp under pressure — it steams. The Ninja Foodi’s SmartLid adds true air-frying, so it finishes with a dry, crackly top the Instant Pot simply can’t produce.
Everything else. The Instant Pot Duo is the lighter, smaller machine with fewer parts, the enormous recipe ecosystem, and the value price ($$, around $100). The Ninja Foodi is bulkier and heavier, carries a growing-but-smaller community, and lands a step up ($$$) to pay for the air-fry hardware.
The real difference: crisping and air-fry
If you remember one thing from this comparison, make it this. Every other difference — price, size, recipe support — flows from a single design choice: the Ninja Foodi adds crisping and the Instant Pot doesn’t.
Pressure cooking is a moist-heat method. It’s brilliant for anything you’d normally braise, stew, or simmer for hours — but it can’t brown, and it can’t crisp. That’s true of the Instant Pot Duo and, under its pressure lid, of the Ninja Foodi too. The difference is that the Ninja Foodi has a second trick. Its SmartLid switches from pressure cooking to air-frying, and its SteamCrisp mode combines steam and crisping, so you can pressure cook chicken thighs until tender and then crisp the skin in the same pot, or roast a batch of potatoes to a crackly finish without a separate machine. For a lot of cooks, that finish is the whole reason to buy one appliance instead of two.
The Instant Pot Duo answers a different question. It is a focused, do-one-thing-well pressure and slow cooker, and its refusal to also be an air fryer is part of why it’s cheaper, lighter, and simpler. If you want crispy results, you’d pair it with a standalone air fryer — which is a perfectly good setup if you already own one, or if you’d rather keep two dedicated machines than compromise on either.
So the real question isn’t “which is better?” It’s “do I want a crisp finish from my multicooker?” If yes, the Ninja Foodi is built for it. If no, you’re paying for hardware you’ll never switch on, and the Instant Pot is the smarter buy. Air-fry curious but not sure a multicooker is the right way to get there?

Size, price, and recipe support
Beyond crisping, the two machines diverge on the practical stuff — space, cost, and how easy they are to live with.
Size and storage. The Instant Pot Duo is the more compact, lighter machine with fewer parts to wash and stash. The Ninja Foodi is bulkier and heavier, and because it carries a second (crisping) lid plus an air-fry basket, there’s simply more of it to store. That said, if it lets you retire a separate air fryer, it can be the space-saving choice overall — one larger box instead of two.
Price. The Instant Pot Duo is the value pick, sitting around the $100 mark ($$). The Ninja Foodi costs more ($$$), and that gap is mostly the air-fry hardware. If crisping matters to you, that premium buys a genuine second function; if it doesn’t, it’s money spent on a mode you won’t use.
Recipe support. This is quietly one of the Instant Pot’s biggest advantages. Its community is vast, so whatever you want to make — a specific bean, a particular cut, a family recipe — someone has already dialed in the timing and posted it. The Ninja Foodi’s library is smaller but expanding. New to electric pressure cooking in general? Our best electric pressure cookers guide walks through the wider field.
The verdict: who should buy which
Buy the Instant Pot Duo 7-in-1 (6-Quart) if pressure and slow cooking is the point, you want the simplest, cheapest, most-supported machine, and you already own an air fryer or don’t want one. It is the easiest multicooker to recommend to a first-time buyer and the one with the least to learn.
Buy the Ninja Foodi 6.5-Quart Pressure Cooker & Air Fryer if you want one appliance that pressure cooks and air-fries and crisps, you’re short on cabinet space for two machines, and you don’t mind the extra size, price, and parts. The crisping is real, and for the right cook it’s worth every bit of the premium.
Both do the core cooking well, and neither is a mistake. The deciding factor is crisping — pick the machine whose strengths match how you actually cook, and you’ll be happy with it.
Beyond these two
These are the two names most people compare, but they aren’t the only strong options.

And if you specifically want higher pressure, a hotter sear, or the only kind of cooker that’s safe for canning, our best stovetop pressure cookers guide is where to look next.
Using either safely
Whichever you choose, the fundamentals are the same. Use natural release — letting pressure fall on its own — for meats, stocks, and foaming foods to avoid sputter, and quick release — venting manually — for vegetables when you want to stop the cooking fast. Don’t overfill: keep to two-thirds full at most, and only half for foaming foods like beans, grains, and pasta. Add enough liquid (electric cookers generally need about a cup minimum), keep liquids thin under pressure and thicken afterward, and keep the sealing ring and vent clean. Never force the lid open. Our how to use a pressure cooker guide covers all of this in detail.
One hard line on both machines: do not use either for canning low-acid foods. The National Center for Home Food Preservation (NCHFP) does not recommend pressure canning in electric multicookers, because they may not reliably reach or hold the temperatures needed to make canned low-acid food — vegetables, meat, poultry, stock — safe. This is an equipment-safety fact, not a preference. To pressure can low-acid food safely, you need a tested stovetop pressure canner with a dial or weighted gauge; see our best stovetop pressure cookers guide for the canning-suitable options.
