Instant Pot Duo Plus 9-in-1 Review (2026)
Instant Pot Duo Plus review: 9 functions, whisper-quiet steam release, 6-quart capacity, and who should buy it.
Instant Pot Duo Plus 9-in-1 6-Quart
The standard-setter: 9 functions, quiet steam release, proven at scale.
Our verdict
The Duo Plus is the pressure cooker to buy if you are buying your first one or replacing an old loud model. The trade-off is clear: you get the quietest steam release and most forgiving lid in the class, but you give up air frying and the larger capacity some families need. Nine functions cover everything most households actually cook, and the stainless-steel pot will outlast nonstick alternatives.
What we like
- Nine cooking functions cover pressure cooking, slow cooking, rice, yogurt, steaming, sauteing, sous vide, sterilizing, and keep-warm in one 6-quart pot.
- Whisper-quiet steam release with an auto-seal lid removes the two most intimidating parts of pressure cooking for beginners.
- The stainless-steel inner pot is dishwasher-safe and the best-selling size has years of documented reliability.
What to watch out for
- Slow-cook mode heats from the bottom only and runs cooler than a dedicated slow cooker; results are acceptable, not equivalent.
- No air-frying or crisping function, so anything that needs browning requires a separate appliance or the oven.
- The 6-quart capacity gets tight for batch cooking or families larger than six.
Who it is for
First-time pressure cooker buyers and households of two to six who want one reliable multi-cooker.
Cooking performance
The Duo Plus pressure-cooks as well as any 6-quart electric model: beans, tough cuts, and stocks finish in roughly a third of stovetop time. The saute function browns adequately for building flavor before pressure cooking, though it does not sear like a ripping-hot skillet. Slow-cook mode works but heats from the bottom only, so it runs cooler than a dedicated Crock-Pot; plan on the high setting or longer times. The sous vide and yogurt modes are genuine bonuses that work as advertised, not marketing filler.
Ease of use
This is where the Duo Plus earns its reputation. The lid seals automatically when you close it, eliminating the classic beginner error of forgetting to set the valve. The whisper-quiet steam release vents with a controlled hiss instead of the startling jet of older models, which matters more than specs suggest: it is the main reason nervous first-timers actually keep using the thing. Fifteen smart programs cover the common foods, and the interface is button-based but logical.
Build and maintenance
The stainless-steel inner pot is the right call for a daily-use appliance: it tolerates metal utensils, does not degrade like nonstick, and goes in the dishwasher. The sealing ring is the wear item; expect to replace it every 12 to 18 months, and buy a spare because a stretched ring causes the steam leaks that generate most one-star reviews. The exterior wipes clean and the lid components disassemble for washing.
How it stacks up
Against the Instant Pot Pro, the Duo Plus gives up faster preheating, the gentle steam diffuser, and programmable favorites, but the core pressure-cooking results are identical and it costs less. Against the Ninja Foodi Deluxe, the Duo Plus is smaller, quieter, and simpler, but it cannot crisp food; if browned finishes matter to you, the Foodi's TenderCrisp lid is the reason to pay more and accept a much taller unit.

Questions, answered
How quiet is the whisper-quiet steam release really?
It vents with a controlled hiss rather than the loud jet of older models. You can hold a conversation next to it; you could not with the original Duo.
Can the Duo Plus slow cook as well as a Crock-Pot?
Acceptably but not equivalently. It heats from the bottom only, so use the high slow-cook setting and allow extra time versus a ceramic slow cooker.
Is the 6-quart big enough for meal prep?
For four to six servings, yes. If you batch-cook for a large family weekly, the 8-quart class (like the Ninja Foodi Deluxe) saves you from running double cycles.
