Ninja 12-in-1 PossibleCooker Plus Review: Is the 8.5-Qt Multi-Cooker Worth It?

We tested the Ninja PossibleCooker Plus for 6 weeks — slow cooking, searing, and sous vide. Here's what the 8.5-qt multi-cooker gets right and where it falls short.

Ninja 12-in-1 PossibleCooker Plus Review: Is the 8.5-Qt Multi-Cooker Worth It?

Pros and cons

Pros

  • Replaces 12 appliances: slow cooker, Dutch oven, roasting pan, skillet, sauté pan, and more — one machine instead of a cabinet full
  • Sear and sauté directly in the pot without a separate stovetop pan
  • Oven-safe removable pot up to 500°F for finishing with a crispy top without switching vessels
  • Triple Fusion Heat Technology cooks up to 30% faster than conventional ovens — tested on 6-lb whole chickens
  • 8.5-quart capacity handles big batches: 9-lb brisket, chili for 20, or proofing two loaves at once

Cons

  • No pressure cooking function — dried beans and quick weeknight meals require the slow cook setting instead
  • Cooking pot requires hand-washing to preserve the nonstick coating
  • Larger footprint than compact multi-cookers — measure your counter space before buying

If you want to make a beef stew on a Sunday afternoon without staring at a stovetop, the Ninja PossibleCooker Plus is built for that. It replaces 12 appliances and does its best work when you're feeding a crowd — not micromanaging a meal. After 6 weeks of testing, here's what works, what doesn't, and who should buy it.

Quick verdict

The Ninja PossibleCooker Plus earns its place on the counter if you want one machine that slow-cooks, sears, sous vides, and braises without swapping pots. The oven-safe pot up to 500°F and the built-in spoon-ladle are genuinely useful touches. Skip it only if you need pressure cooking speed — that function simply isn't here.

Who is this for?

Home cooks who entertain and want a set-it-and-forget-it machine that can handle a brisket or a big pot of chili without a stovetop babysitter. It also suits anyone who likes the idea of sous vide but doesn't want a separate water oven. If your kitchen is tight on counter space, the 8.5-quart footprint is worth measuring first — it's wider than most slow cookers.

Key features

12 appliances in one body

Ninja's core claim is replacing your slow cooker, Dutch oven, roasting pan, cast iron skillet, sauté pan, saucepan, stock pot, saucier, food warmer, bread maker, and utensil. The value isn't that it does each job equally well — it's that you buy one machine instead of a lineup of single-purpose pots. For renters or kitchens without wall ovens, this matters more.

8.5-quart cooking capacity

Enough room for a 9-pound brisket, spaghetti for 20, or two loaves of bread proofing side by side. The size is the main differentiator from compact multi-cookers like the Instant Pot Duo.

6 cooking functions

Slow Cook, Sear/Sauté, Keep Warm, Sous Vide, Braise, and Proof. The dial-based interface makes cycling through modes straightforward with no app required.

Triple Fusion Heat Technology

Combines bottom, side, and steam heat. Ninja says this cuts cooking time by up to 30% versus conventional ovens, tested on 6-pound whole chickens. In practice, the steam component helps with braising and proofing bread without drying the crust.

Oven-safe to 500°F

The removable cooking pot goes directly into the oven. That means you can sear a pork shoulder in the pot on the counter, then transfer the whole thing to the oven to finish — no switching vessels. A crispy top on a casserole happens without a separate baking dish.

Real-world performance

The sear function works. It won't replace a cast iron skillet for a hard sear on a thick steak, but it builds fond on chicken thighs and vegetables without preheating another pan. That matters when you're making a braised chicken dish and don't want to juggle two cookware pieces.

Slow cooking is where this machine earns its keep. A 6-hour chuck roast came out tender with zero monitoring. The Keep Warm function smoothly takes over when the cycle ends — it doesn't overcook while you finish the rest of dinner.

Sous vide mode requires a compatible probe thermometer for best results — the unit itself doesn't include a built-in temperature probe. Set a target time and the unit heats to the sous vide range. It's a different workflow from a dedicated sous vide circulator, but it works for those who want to experiment without a second appliance. Serious sous vide cooks may still prefer a dedicated water oven for precision and batch capacity.

Cleanup is straightforward — the nonstick pot releases most residues with a quick wipe. The cooking pot needs hand-washing to preserve the coating. The glass lid and included spoon-ladle are dishwasher safe.

Verdict & price check

For home cooks who want one machine to slow-cook, braise, sear, and sous vide without a wall of single-purpose cookware, the Ninja PossibleCooker Plus delivers. The oven-safe pot and integrated utensil are small touches that make it more usable day-to-day. The missing pressure cooking function is a real gap — if beans and weeknight shredded chicken speed are priorities, look elsewhere. For everyone else, it's a solid entertainer's machine at a reasonable price. Check the latest price for the Ninja PossibleCooker Plus on Amazon

Frequently asked questions

What does the Ninja PossibleCooker Plus replace?
Ninja lists 12 appliances it can replace: slow cooker, food warmer, nonstick pot, sauté pan, cast iron skillet, saucier, saucepan, stock pot, Dutch oven, roasting pan, bread maker, and utensil. It's a single machine that covers most of the heavy-lifting cookware in a kitchen.
How does the sous vide function work on the PossibleCooker Plus?
The sous vide mode heats the cooking pot to a precise water temperature for slow, even cooking of proteins in sealed bags. For best results, Ninja recommends pairing it with a compatible probe thermometer. It's a solid feature for beginners wanting to try sous vide without a dedicated water circulator.
Can I use the cooking pot in the oven?
Yes — the removable cooking pot is oven safe up to 500°F. You can sear on the base unit and finish in the oven in the same pot without transferring to a separate baking dish.
How do I clean the Ninja PossibleCooker Plus?
The nonstick cooking pot should be hand-washed to extend its coating life. The glass lid and included multi-functional spoon-ladle are dishwasher safe. Wipe the base unit with a damp cloth — it's not waterproof.
