Best Combi Steam Oven 2025: Nuwave Reviewed

The best combi steam oven does something no standard air fryer or convection oven can pull off alone: it combines precise steam infusion with dry heat, giving you food that's simultaneously juicy on the inside and genuinely crispy on the outside. That's not a marketing promise — it's basic food science, and countertop appliances that actually execute it well are rare.

For years, combi steam cooking was locked behind commercial kitchen equipment with four-figure price tags. That's changing fast. Countertop models have caught up in a meaningful way, and shoppers are catching on — searches for best combi steam oven have spiked as home cooks realize a single machine can replace a toaster oven, air fryer, sous vide setup, and more.

We evaluated the Nuwave Combi Steam Oven on its core cooking modes, temperature precision, preset library, and real-world ease of use. Here's our honest take on whether it belongs on your counter.

Editor's Pick

Nuwave built the Combi Steam Oven for home cooks who are tired of juggling three separate appliances and still ending up with chicken that's dry inside or salmon that's mushy outside. The standout feature is the COMBO mode, which simultaneously runs steam and air fry — you get the moisture retention of a steam oven and the browning power of a convection fryer in one pass. Temperature control runs from 50°F all the way to 450°F in 1°F increments, which matters enormously for sous vide work where a few degrees separates perfect medium-rare from overcooked. The bag-free Air Sous Vide approach is genuinely clever — no plastic bags, no water bath, no separate machine — just moisture control dialed between 10% and 90% alongside precise heat. The 120 presets lower the learning curve significantly, and the non-toxic stainless steel interior makes cleanup far less miserable than nonstick-coated alternatives. If you're not interested in the precision cooking side and just want a basic toaster oven, this is more machine than you need — but anyone who wants restaurant-quality results at home without culinary school experience will find this 16-quart unit punches well above its countertop footprint.

Why we picked it

I recommend the Nuwave Combi Steam Oven as my top pick because it solves the core problem every serious home cook faces: getting food that tastes like it came from a real kitchen, not a reheated approximation of one. The combination of wide temperature range, fine-grain precision, and adjustable moisture control means you're not locked into preset cooking logic — you can actually dial in results the way a chef would. That 50°F floor opens up true low-temperature cooking that most countertop ovens can't touch.

I'm confident recommending this to anyone who cooks regularly and wants to consolidate their appliance collection without sacrificing capability. It's especially well-suited to households where someone is health-conscious — the sous vide mode renders fat gently without burning, and the steam function means you need far less added oil to get satisfying texture. The 4.4-star rating across 129 reviews reflects a machine that delivers on its promises for real users, not just spec-sheet performance.

The bottom line

If you're shopping for the best combi steam oven for home use, the Nuwave Combi Steam Oven is the clear recommendation for most buyers. It's the only pick on this list, and it earns that position honestly — the combination of bag-free sous vide, true combi steam-and-air-fry mode, 1°F temperature precision, and a 120-preset library makes it a genuinely versatile kitchen tool rather than a one-trick gadget. The non-toxic stainless steel build and easy-clean interior mean it's also a long-term investment, not a novelty you'll retire to a cabinet after six months.

It's worth repeating: Nuwave designed this for people who want gourmet results without gourmet complexity. If that's you — and it's most of us — stop second-guessing and add it to your counter.

Frequently asked questions

Do I need special bags or equipment for the sous vide function?

No. The Nuwave Combi Steam Oven uses what Nuwave calls Air Sous Vide — you control temperature and moisture levels directly in the oven cavity, so there's no need for vacuum bags, a separate immersion circulator, or a water bath. It's a cleaner, more eco-friendly approach to low-temperature precision cooking.

Can the Nuwave Combi Steam Oven actually replace my air fryer and toaster oven?

For most households, yes. It handles air frying, toasting, steaming, combi cooking, and sous vide in one 16-quart unit. If you rely heavily on a large standalone air fryer for big batches, check the 16-quart capacity against your typical cooking volume — but for a family-sized kitchen, it consolidates the core functions of several appliances.

How precise is the temperature control, and does it matter for everyday cooking?

The oven adjusts in 1°F increments across a 50°F–450°F range. For everyday roasting or toasting, that level of precision isn't critical — but for sous vide and delicate steam cooking, it genuinely matters. A few degrees can change the texture of fish or the doneness of steak, so having that granular control gives you repeatable, predictable results over time.
