Built Like Commercial Bakeware. Priced for Your Kitchen.

Every detail targets a reason your old pans ended up in the trash.

Diamond Airflow Floor

About 1,200 raised micro-diamonds per Half Sheet cut food-to-metal contact by 42%. Cookies slide off and air moves underneath for even browning.

Warp-Lock Rolled Rims

A 4.5mm steel rod sealed inside each rim holds the 0.8mm body flat at 450°F. No bang, no twist, no oil pooling in one corner.

4 Pieces, One Drawer

Quarter Sheet, Jelly Roll, and stainless rack nest inside the Half Sheet in a 1.6-inch stack. No handles to snag.

Clean, Non-Toxic Release

PTFE, PFOA, and PFAS-free champagne glaze. Burnt glaze and baked cheese wipe off in about 15 seconds with a soft sponge.

How the Aurelia ProSheet Works

Diamonds Lift Food Off the Metal

Diamonds Lift Food Off the Metal

The stamped diamond floor lets cookies and vegetables rest on tiny raised points. Less contact means cleaner release, and the small air channels underneath help bottoms bake pale-golden instead of scorched.

Thick Steel Stays Flat at 450°F

Thick Steel Stays Flat at 450°F

The 0.8mm carbon-steel body and rod-reinforced rims resist the uneven heating that makes thin pans twist. Your oil stays spread across the pan, so everything browns at the same rate.

Rack Nests for 360° Crisping

Rack Nests for 360° Crisping

Set the footed 304 stainless rack inside the Half Sheet to lift bacon, wings, or cutlets 0.6 inches above the drippings. Hot air reaches every side, and the grease stays in the pan.

Why Choose the Cosari Aurelia ProSheet?

Cosari Aurelia ProSheet Detail

Twice the Steel

0.8mm carbon steel versus the 0.4mm typical of supermarket pans. You feel the difference when you lift a 4-pound chicken one-handed.

Real Convection Roasting

The nested stainless rack lifts food above drippings so hot air crisps all sides. Bacon and wings come out crisp, not soggy.

Fits the Drawer You Have

All four pieces stack 1.6 inches tall, small enough for the shallow warming drawer under most ovens.

Pale golden cookie bottoms and zero parchment paper

My old dark gray supermarket pans absorbed way too much heat and burned chocolate chip cookie bottoms before the centers could even set. The light champagne-gold finish on the Aurelia Half Sheet bakes evenly pale golden bottoms every single batch, and cookies literally skate right off that diamond texture like pucks on an air-hockey table. Haven't bought a roll of parchment in months.

Built like pastry-shop gear and nests flat in one drawer

You can feel the steel rod inside the rolled rims as soon as you lift them—zero flex even pulling a 4-pound spatchcocked chicken out of the oven with one mitted hand. Having the 304 stainless wire rack sized right to drop into the Half Sheet makes oven bacon and chicken cutlets ten times crispier, and all three pans plus the rack still stack into the height of one pan in the shallow drawer under my stove.

No more terrifying oven BANG at 425 degrees

I finally threw out my thin aluminum pans after hearing that loud gunshot pop at 425°F and opening the oven door to find sweet potatoes swimming in olive oil in one tilted corner while the high side charred black. Roasted broccoli and halved Brussels sprouts at 450°F four times this week on the Cosari Half Sheet and Jelly Roll—dead flat from corner to corner.

Baked-on cheddar lifted off in one piece

Made sheet-pan smashburgers at 400°F on Friday night and sharp cheddar melted right off the patties onto the bare pan. On my old pans that meant twenty minutes of soaking and steel wool. On this diamond surface, the crisped cheese lifted right off in one lacy cracker and warm soapy water with a soft sponge had the pan looking brand new in 15 seconds.

Way better than the $115 trendy ceramic pan I regret buying

I fell for those expensive Instagram ceramic sheet pans last year and within five months roasted cauliflower was welding itself to the center like glue. Took a chance on this Cosari 3-piece set at half off and the nonstick release isn't even comparable. Sticky honey-garlic salmon skins slide off intact without foil or spray.

The Quarter Sheet gets used every single morning

Honestly thought I was buying this set for the big Half Sheet, which is great, but the Quarter Sheet is the unsung hero of our kitchen. I grab it every morning for crispy hashbrowns, reheating two slices of leftover pizza, or roasting a bunch of asparagus just for my wife and me without heating up a massive pan.

Replaced my oxidized gray aluminum pans for good

My husband accidentally ran our bare aluminum sheet pans through the dishwasher once and they came out coated in chalky gray oxidation residue that rubbed off on paper towels forever. I strictly hand-wash these Cosari pans in the sink, which honestly takes ten seconds with a soapy sponge because nothing polymerizes onto the surface.

Substantial weight—just measure your smallest toaster oven

Rock-solid build quality. Zero twisting when roasting two pounds of cold carrots straight from the fridge into a 450°F oven. Knocking off half a star in my head only because the heavy rolled rim on the Quarter Sheet was 3mm too wide for my tiny compact countertop toaster, though it fits our standard oven racks like a dream.

Pretty enough to leave out on the kitchen island

For the first time in my adult life I don't rush to hide my sheet pans in the oven when friends are standing around the island with wine. That muted champagne-gold diamond finish looks gorgeous sitting on a trivet, and the Jelly Roll size is the exact sweet spot for cinnamon rolls and sheet-pan fajitas.

Done wrapping every dinner pan in heavy-duty foil

Used to go through giant rolls of heavy-duty foil just so I wouldn't be stuck scrubbing brown baked-on oil at 9 PM on a Tuesday. Three weeks of sheet-pan sausage and peppers, glazed drumsticks, and garlic bread on these pans without a shred of foil, and not a single stain left behind.

Frequently Asked Questions

Will the largest pan fit my oven?

The Half Sheet measures 17.5 × 11.8 × 1.0 in, which fits standard US 24-inch and 30-inch ovens. Measure your rack if you have a compact or European oven.

Is the nonstick coating safe?

Yes. The champagne-gold finish is free of PTFE, PFOA, PFAS, lead, and cadmium.

What's the maximum oven temperature?

All four pieces, including the stainless rack, are oven-safe to 450°F. Avoid broiler use above that.

Is the rack real stainless steel?

Yes. The rack is solid 304 food-grade stainless steel, not chrome-plated, so it won't flake or rust.

Will the Quarter Sheet fit my countertop toaster oven?

At 13 × 9 in, the Quarter Sheet fits the Breville Smart Oven Air and most countertop ovens built for 9 × 13 pans. Check your interior dimensions to be sure.

Can I put the pans in the dishwasher?

They tolerate the top rack, but we recommend hand-washing. Harsh detergent pods will dull the finish over time, and hand-washing takes about 15 seconds because food doesn't stick.
