If you’re asking whether the Instant Pot Omni Plus is worth it for a family that cooks daily, the short answer is yes — but only if you actually need the oven-style capacity and the stainless steel interior matters to you.
I started looking into this model after we outgrew our basket-style air fryer. With a family of four and two hungry teenage boys, cooking in rounds every night stopped being practical. Here’s what I found after putting the Omni Plus through real family use.

Why the Stainless Steel Interior Is the Real Selling Point
Most air fryers — even ones marketed as “ceramic” — still have nonstick coatings somewhere in the cooking chamber. The Instant Pot Omni Plus is different: the interior walls and cooking trays are stainless steel, which means there’s no coating to scratch, no PTFE to worry about, and no degradation over time.
The FDA has noted ongoing concerns about PFAS exposure through cookware, which is exactly why a fully stainless interior matters for families cooking daily. You’re not relying on a coating staying intact — the surface itself is inert.
Real Family Use: What Works and What Doesn’t
The 18-liter capacity is the biggest practical advantage. We can fit a whole chicken, a full rack of ribs, or enough fries for four people in a single batch. No more cooking in rounds while half the family waits.
The nine cooking functions get used more than you’d expect. We use air fry and roast the most, but the dehydrate setting has been surprisingly useful for making snacks for the boys — apple chips, beef jerky strips, that kind of thing.
The Omni Plus handles a whole chicken without breaking a sweat — that capacity is the real game-changer for families.
Where it’s less impressive: the exterior gets hot during long cooking sessions, so you want to keep kids away from the sides. It also takes up meaningful counter space — this is not a compact appliance.
Is the Cooking Performance Actually Good?
Yes, with one caveat. The stainless steel trays don’t have nonstick properties, so food can stick if you don’t use parchment paper or a light oil spray. Once you get into that habit, results are consistently good — crispy outside, properly cooked inside, and no chemical smell even on the first use.
Preheat time is slightly longer than a basket-style air fryer, which is expected at this size. Budget an extra 3–5 minutes compared to a compact model.
Stainless steel trays mean no coating worries — just use parchment paper to prevent sticking.
Who Should Buy the Instant Pot Omni Plus?
- Families of 4 or more who are tired of cooking in batches
- Health-conscious households who want a fully PFAS-free cooking surface
- People replacing a toaster oven — this does everything a toaster oven does, safer and faster
- Meal preppers who need large-batch capacity on a regular basis
It’s not the right pick if you’re cooking for one or two people, or if counter space is limited. In that case, the Ninja AF150AMZ is a better fit.
Worth It? Here’s My Honest Take
For a family that cooks real food every day and wants to move away from nonstick coatings completely, the Instant Pot Omni Plus is one of the few appliances that actually delivers on both fronts — capacity and material safety. It’s not cheap, and it’s not small, but it earns its place on the counter.
If the stainless steel interior and the large capacity match what your family needs, it’s worth every dollar.
