Best Countertop Steam Ovens of 2026

Continuous steam is what separates the Cuisinart CSO-300N1 from everything else in this group. It will run steady, uninterrupted steam for up to 120 minutes — long enough for a whole fish, a batch of dumplings or a custard — where the other ovens here use steam as a burst of moisture inside a dry cycle. That one capability is why we keep it as the pick for anyone who actually wants to steam food, and the nine single and combination functions around it mean it isn't a one-trick machine.

Bread is where the steam earns its keep twice. The proofing setting and a steam-injected bake give you the crust and the rise a dry countertop oven can't, and the 0.6-cubic-foot cavity still swallows a whole 4.5-lb chicken or a 12-inch pizza, which is a small family's dinner rather than a crowd's. The controls are dials, which we prefer to a menu: turn to steam, set the time, walk away.

Depth is the catch. At 23.15 inches front to back and 23.4 pounds, it takes nearly the entire depth of a standard 24-inch counter, leaving barely an inch behind it and no room to set a hot pan down in front of the door. In a small kitchen that usually means a cart or an island end rather than the main run, and it's worth measuring that before anything else.

A moisture percentage is the dial the Nuwave gives you, anywhere from 10% to 90%, and that's a different idea of steam than a mode you switch on. Set a temperature between 50°F and 450°F in one-degree steps, choose how wet you want the air, and the oven holds that combination for the whole cook: 90% for proofing dough or bringing rice back to life, 10% when you want the skin on a chicken to brown. That's a control we came back to more than any preset.

Air sous vide is the party trick, and unlike most party tricks it's useful: a low, precise hold gives you salmon or pork loin without a water bath, a vacuum bag or a second appliance on the counter. The 16-quart cavity is smaller than the 24- and 25-quart boxes here, so this is a two-to-four-person oven rather than a holiday one, and the stainless interior carries no PFAS coating, which matters if that's why you're shopping.

Control is what you're paying for, and it's worth it if you prefer cooking by numbers to picking a mode name. Once a temperature and a moisture level are dialed in, the results repeat in a way a preset oven's don't, and that's the case for choosing this over the Ninja even though it holds less and costs more. The trade is a preset workflow that fights you every time you try to save something of your own.

Twenty-five quarts is the biggest cavity in this group, and the CIARRA Nosh Oven Pro gets there in a body 16 inches wide and 17 tall — a family-sized oven that still leaves room on the counter for a cutting board. The 1500-watt element runs from 85°F to 430°F, so the same box proofs dough at the low end and broils at the top, and the steam, rapid steam and steam-bake modes cover everything in between.

What we didn't expect to like as much as we do is the sterilize setting, which turns the cavity into a bottle and jar sanitizer — a genuinely useful second life for an appliance this size, and the sort of thing that makes the case for keeping it out on the counter. The mode list runs long: air fry, bake, broil, dehydrate, ferment, self-clean and delay start, and the two years of warranty are the longest coverage on this page. This is a big-oven replacement rather than a weeknight shortcut.

The case against it is pace. With 25 quarts to heat, expect it to take longer to come up to temperature than the Ninja's 1760 watts in a much smaller cavity, and it's a lot of oven to run for a bagel. Buy it when the guest count is the deciding factor; the rest of this list handles small jobs more gracefully, and the Cuisinart does steam far better.

The steam in the Tovala Smart Oven Pro is a moisture assist, not a steamer. It keeps a salmon fillet from drying out and gives a bake a better crumb, but you can't load a tray of dumplings and expect them cooked through — for that you need the Cuisinart. Six modes (steam, air fry, bake, broil, toast, reheat) run from a phone, and the app is the product.

Where it earns its place is dinner with no decisions. Scan the barcode on a Tovala meal or on one of the thousand-plus grocery brands the app knows, and it sets the mode, temperature, time and steam for you, including combinations most of us wouldn't think to set. Cooking quality is the strongest thing about it: vegetables come out browned rather than collapsed, and the whole appeal is that you stop making choices.

What it isn't is quick or simple. Toast takes longer than a toaster, and the oven is at its best when it's cooking its own food. The meal subscription is an ongoing cost on top of the appliance, so the convenience carries a monthly bill as well as a counter footprint of 18.5 inches wide and 11.75 inches tall — the shortest body here, and the easiest to tuck under a cabinet.

So the case for it is narrow and specific: we think it's a good buy for someone who wants guided cooking and will use steam as a texture tool on roasts and bread. If what you want is an oven that steams, this one can't, and the Cuisinart can — that's the whole decision.

Four appliances in one box is the Midea's pitch — a 900-watt inverter microwave, a steamer, an air fryer and a convection oven — and it's the only pick here that can genuinely replace a microwave. Whether that trade works depends on which one you use most: the microwave and the steam are strong, and the air fry and bake modes are the compromise.

The steam side is the pleasant surprise. Dual steam tubes bring high-temperature vapor up in under 30 seconds, fast enough to be useful for a bowl of vegetables, and the 32 auto functions include fermenting, defrosting and a cavity-clean cycle. The app earns its keep too — preheating from another room and getting a finish notification is the kind of feature you stop noticing because it simply works.

The compromises are physical, and the small-kitchen pitch is the shakiest part of the sales copy. At 53.4 pounds and 19.7 inches deep this is the heaviest thing on the page, and the weight is not a spec-sheet abstraction when you're sliding it onto a shelf. Baking and air frying are the least convincing of the four modes; expect to rotate the pan and to give thicker items more time than a dedicated air fryer needs.

The OUNIN is the same oven as the CIARRA on paper, in a different set of units: 24 liters and 25.4 quarts are the same capacity, the same 11-in-1 list of steam, convection bake and air fry applies, and both bodies sit around 17 inches deep. The differences that survive the comparison are 1600 watts against 1500, a black exterior against cream, and the CIARRA's two-year warranty, which is the tiebreaker for us. That's why this one sits behind it.

What the extra wattage buys is a hotter 360-degree air system, with a claim of roasting up to 30% faster than a traditional oven, plus a basket, baking pan, wire rack, oven mitt and recipe book in the box. Steam, convection bake and air fry are separate settings rather than one blended mode, so you decide how much moisture a cook gets instead of trusting a preset to guess. One thing the spec sheet settles: at 17 inches deep it needs more counter depth than the Ninja, so it isn't the pick for a galley kitchen.
