Best Steam Toaster Ovens of 2026

Five cubic centimeters — roughly a teaspoon — is the entire water supply, and it's measured in the little cup that comes in the box. You spoon it in, the oven turns it into a burst of steam, and three separately controlled heating zones work the bread at the same time: strong top heat for color, gentler heat below, and a middle zone that keeps the crumb soft while the crust sets.

The result is the best toast in this group, and the only one here that made us want to keep a better loaf in the house. The modes are named for what they do — Shokupan, Golden Toast, Croissant, Pizza — alongside a conventional Oven setting at 350°F, 400°F or 450°F and a Salamander Grill that runs top-down heat like a broiler. That grill mode is the sleeper of the whole machine: it melts cheese and blisters a gratin without heating a full oven for one dish.

Two things to know before you pay for the design. The baking tray is sold separately, which stings on an appliance this expensive, and the cavity is only 8.2 inches tall — a slice, a croissant or a small gratin dish fits; a chicken does not. Wide slices can also brown unevenly, so rotate the rack halfway if you're going bigger than sandwich bread.

At 9.7 pounds it's the lightest oven here by a wide margin, and that's the quiet appeal for a small kitchen: it can live on a shelf and come down when you want it. If a bakery crust at home is the goal, this is the one that gets you there.

Most steam ovens give you one dose of water and hope for the best. The Nuwave lets you set the moisture level itself, anywhere from 10 to 90 percent, and hold it through a cook at any temperature between 50°F and 450°F. That's a different proposition from a burst of steam at the start: you can run a long, humid bake for bread or a dry, high-heat finish on vegetables, and change your mind about which one you want mid-recipe.

The low end is the part shoppers skip past. At 50°F with high humidity it does bagless sous vide, so salmon and chicken come out silky without a water bath or a vacuum sealer, and the same range handles proofing dough and reheating leftover bread without turning it to cardboard. Toast comes out with a crisp shell and a soft middle rather than a dry cracker.

We think the control is worth paying for if you actually cook, and unnecessary if you mostly toast. It's also the heaviest oven here at 21.4 pounds, so it lives where you put it — don't plan on lifting it in and out of a cabinet. Saving your own settings is the weak spot: the panel takes more presses than it should, and there's no number pad to shortcut the process.

Sixteen quarts puts it in the middle of this group — more room than the compact steam toasters, less than the 25-quart CIARRA — and sized for a two-person kitchen that cooks fish, vegetables and bread with some attention.

At 25.4 quarts, the CIARRA is the biggest cavity in this roundup, and the size isn't marketing inches: it swallows a 5-pound chicken, a covered Dutch oven for sourdough, or a full tray of vegetables with room for air to move. If your reason for wanting steam is Sunday baking and a weeknight roast rather than breakfast toast, start here.

Steam comes in three forms — steam, rapid steam and steam bake — and rapid steam is the useful everyday setting, hitting fish and chicken with moisture before the convection fan finishes the surface. The mode list also covers air fry, dehydrate, ferment and reheat, and the self-clean cycle plus a removable crumb tray make the after-dinner part less of a chore than the size suggests. We think it's the oven here that behaves most like a small second oven rather than a toaster with ambitions.

The 17-inch height is the compromise, and it's what buys all that rack space — just measure the gap under your upper cabinets before you commit, because this one is not sliding under a shelf. The temperature range also starts at 85°F, low enough to proof dough and ferment, which the smaller ovens here can't do.

Controls are touch plus a knob, and the two-year warranty is the longest stated in this group — worth knowing, because if the door ever stops sealing, the gasket is the first place to look. In price it sits in the middle of this set, well under the compact premium toasters, for several times the interior.

The first thing we noticed lifting the OUNIN out of the box is how little counter it asks for: a 12-liter box on a 10-by-10-inch footprint, dials instead of a display, and a 60-minute timer that shuts the oven off when it runs out. Nothing about it feels grand, but nothing about it feels flimsy either, and the steam function is real rather than a label.

For toast, bagels and a basket of wings for two, it does the job, and the steam infusion genuinely improves bread that's a day past its best — a crisp crust with a soft middle instead of a dry shard. The dials are the trade-off: no presets, no proof setting, no one-touch anything, so you set a temperature and a time and watch through the glass the way ovens used to work.

Size is the honest limitation. Twelve liters is a two-person oven — toast in the morning, a small tray of vegetables, a couple of chicken breasts — and a whole chicken is not happening. The single shallow rack means you're cooking one layer at a time, not a full dinner.

Twelve pounds is the other practical advantage: you can lift it off the counter and into a cabinet when the kitchen needs the space, which none of the larger ovens here make easy. And the 450°F ceiling means it will broil a piece of fish or finish a grilled cheese, even without a preset to tell it how.
