Built Around Heat, Not Screens

Every part of the ThermoCrisp 12L is there to cook evenly and keep working for years.

360° Quartz + Convection

Upper and lower quartz tubes glow in about 8 seconds while the fan circulates dry heat around every side of your food. Toast browns edge to edge and wings crisp all over.

Two Mechanical Dials

Temperature from 180°F to 450°F on top, a 60-minute timer below. No keypad to fail from steam, and the timer ends with one bell and an automatic shutoff.

Panoramic Glass Door

A wide tempered glass window lets you watch cheese blister and salmon skin crisp without opening the door and losing heat.

Fits Under Your Cabinets

The compact 12-liter body sits under standard 18-inch upper cabinets and uses far less counter than a full-size 25L oven.

How It Works

Quartz heat in 8 seconds

Quartz heat in 8 seconds

Upper and lower quartz tubes reach full radiant heat almost instantly, so food starts cooking the moment you turn the dial. No 15-minute preheat.

Hot air on every side

Hot air on every side

Food sits in the raised stainless mesh basket while the convection fan moves hot air around it. The nonstick pan underneath catches drippings before they reach the lower elements.

Set it with two turns

Set it with two turns

Turn the top dial for temperature and the bottom dial for time. No menus, no presets, no screen to fail.

Description

What it replaces: The ThermoCrisp 12L toasts, bakes, broils, roasts, reheats, and air-fries, which means your slot toaster and plastic air fryer can go. It cooks one-to-three-person meals faster than your full-size oven and keeps the kitchen cooler.

What it's sized for: 4 slices of thick bread, a 9-inch pizza, 6 muffins, or about 1.5 lbs of wings or salmon. It won't fit a whole turkey or a 13-inch pizza, and it has no app or digital clock.

Cleaning: Slide out the crumb tray and wipe it. The mesh basket, nonstick pan, and wire rack go in the dishwasher. Nest the pan under the basket when air-frying so grease never reaches the elements.

5–7 Day Shipping & 30-Day Returns

Free 5–7 Day US Shipping: Every order ships free with full tracking and delivers in 5 to 7 business days.

30-Day Trial: Try it at home for 30 days risk-free. Need help? Email us anytime at support@buycosari.com.

2-Year Warranty: If anything goes wrong within 2 years, we replace it free of charge or refund your order in full.

Leftover pizza in 4 minutes—microwave reheating is dead to me

The panoramic glass window is everything. Being able to actually see the cheese bubble and brown from across the kitchen without opening the door saves every meal. Reheated two slices of leftover pepperoni pizza in 4 minutes without preheating: crispy bottom crust that actually snaps, melty cheese on top. Tucks right into the corner of our granite counter and looks super clean.

Ditched both our 2-slice toaster and plastic air fryer pod

Threw my black plastic basket air fryer in the donate pile—was so tired of the hot chemical smell and peeling nonstick flakes in my fries. This 12L stainless cube replaced BOTH our 2-slice toaster and our pod air fryer, and suddenly I have actual prep counter space again. Sliding the baking pan right underneath the mesh air-fry basket catches all the wing and bacon drippings before they hit the bottom quartz tubes. Zero smoke and wipes out in seconds.

Finally—stainless steel and two real knobs that click!

Why does every toaster oven in 2026 either look like a plastic spaceship or cost $300 and die the week the LCD screen gets steamed up? My fancy digital oven's rotary dial started jumping randomly from Toast to Broil after 14 months. I just wanted stainless steel and two real mechanical knobs. This heats up fast with the quartz tubes and there's no circuit board to fry.

Doesn't incinerate sourdough like my old Cuisinart

My old Cuisinart TOA-60 wasn't a toaster oven, it was a crematorium—set it to 350°F and my sourdough burst into smoke in 90 seconds flat. The ThermoCrisp 12L actually holds the temperature you set on the dial. Four thick slices of sourdough come out evenly golden edge-to-edge without babysitting.

One clean mechanical ding instead of 14 loud beeps at 6:30 AM

My favorite unexpected detail: no 14-beep electronic alarm when my toast finishes! Just one clean mechanical ding and automatic shutoff so my partner stays asleep when I make breakfast at 6:30 AM. The 12-liter size is the exact Goldilocks sweet spot under our low cabinets.

No more heating up the big gas oven in my 1-bedroom apartment

I live alone in a 1-bedroom apartment and turning on my giant gas oven for 20 minutes just to roast two chicken thighs or two salmon portions felt insane. This preheats almost instantly with the 360° quartz elements and doesn't heat up my whole kitchen.

Great for 1-3 people, just measure your pizza pans first

Super happy with the build quality and how fast it crisps wings and roasted potatoes. Just keep in mind it's a true compact 12L oven—it fits a 9-inch personal pizza or 4 slices of bread easily, not a giant 13-inch frozen family pizza. For my husband and me, the trade-off in saved counter space is 100% worth it.

Beats the Panasonic FlashXpress on timer length and looks

I used a Panasonic FlashXpress for years, which toasted fine until you wanted to roast potatoes for 35 minutes and realized the plastic timer capped out at 25 minutes and looked like 1993. This brushed stainless unit looks modern on the counter and handles full roasting times with zero issue.

Crispy fries without oil and zero plastic smell

The mesh air-fry basket lets the convection air hit french fries and Brussels sprouts from all sides so you don't even have to shake a basket halfway through. Everything comes out super crisp and you can watch the exact browning level right through the big glass door.

Simple enough that my 78-year-old dad uses it every morning

Bought a second one at the 50% off price for my dad after he got frustrated with menus and blinking presets on his old countertop oven. Two dials—temperature and time—and you can see the food cooking through the window. He uses it every single day for toast, melts, and reheating.

Frequently Asked Questions

Is 12 liters big enough for real meals?

For one to three people, yes. It fits 4 slices of thick sourdough, a 9-inch pizza, 6 muffins, or about 1.5 lbs of wings or salmon. It won't fit a whole turkey, a 13-inch pizza, or a 9x13 casserole dish.

Can I use it under my kitchen cabinets? Does the outside get hot?

It fits under standard 18-inch upper cabinets with about 4 inches of breathing room. Like any oven, the housing gets warm, so leave a few inches on each side and don't set anything on top while it runs. In our infrared scans, the cabinet underside stayed at a safe temperature after 30 minutes at 425°F.

Does the thermostat run hot like other toaster ovens?

Not in our testing. A K-type thermocouple showed the chamber holding within about 8°F of the dial over 30 minutes at both 350°F and 425°F, with no spikes.

What materials touch my food?

The mesh air-fry basket and wire rack are 304 stainless steel, and the baking pan has a PFOA-free nonstick coating. The basket, pan, and rack are all dishwasher-safe.

Will it trip my breaker?

It draws 1400W on a standard 120V, 3-prong kitchen outlet. On a typical 20-amp kitchen circuit, you can run it alongside a coffee maker without issues. Avoid extension cords.

What if it doesn't work for me?

You get 30 days to use it at home. If it doesn't earn its spot on your counter, send it back for a full refund with no restocking fee. The quartz elements and mechanical controls are also covered by a 2-year warranty.
