Everybody loves our aluminum half sheet pan and rack set – it’s been one of our best selling products for years. But, we’ve had heaps of requests from people all over the USA asking us to create a stainless steel baking pan to go with our best selling stainless steel cooling/baking rack.

Some people didn’t like the fact that you have to hand wash the aluminum pan while others were just really health-conscious and wary of cooking with aluminum. So, we set out to design a stainless steel half sheet pan, but there was one major problem – warping!

We tested dozens of prototypes in our test kitchen, they all cleaned up well in the dishwasher but every single one of them warped quite badly once heated in the oven. Sure, they would (usually) regain their shape once cooled but, every time they warped there was the danger of spilling fats or liquids or misshaping cookies. They simply weren’t good enough. So, we set the engineers a task – find a way to design a stainless steel baking sheet that doesn’t warp. Some said it couldn’t be done – “it’s physics” they cried. Others played with thicknesses and changed the corner shape of the pan until ultimately, they figured it out!

Finally, a Stainless Steel Sheet Pan That Doesn’t Warp!

Combining extra-thick, 304 quality stainless steel with specially designed pan molding we are now, finally, pleased to announce the arrival of our uniquely designed, warp-free stainless steel baking sheets!

We’re pretty proud of these new products and they truly do resist warping – just watch the video. You’ll see how a regular (flimsy) stainless steel pan (one of the many samples we tested) completely buckles, bends and twists in the oven when we add a splash of water to the hot pan. Meanwhile, when water is added to the Checkered Chef stainless steel pan, the water bubbles and fizzles on the surface of the pan but the pan remains straight and flat!

Non Warping Baking Sheet

We do want to impress upon you though, the engineers were right when they said what we wanted was to defy physics. The fact remains that when metal is heated it expands. Check out this article for an explanation of the physics behind it.

There’s nothing we can do about that. This expansion of metal when heated will cause most pans to warp and twist like the top baking pan in the video. We are not magical and we cannot completely defy physics. There are some circumstances, such as very high heat or when cold items or liquids are added to a very hot pan, that may still cause some movement in your baking sheet pan. But, due to the thick, heavy-duty stainless steel we’ve used, any movement will be minimal and barely noticeable.

We’ve created our new stainless steel pans in both the half sheet size (18 x 13”) and the quarter sheet size (9 x 13”) and they come in a variety of sets.

You can purchase the half sheet stainless steel baking sheet with our famous (award-winning) stainless steel cooling rack. There is also a twin pack of this set available (2 pans and 2 cooling racks).

The quarter sheet stainless steel baking pan comes with our best selling quarter size baking/cooling rack. Or you can purchase the quarter pans in a twin pack (2 quarter baking sheets).

If you’re not sure which size you would use more, you might like to try our set which includes one of each, giving you one stainless steel half sheet pan and one stainless steel quarter sheet pan.

So, whether it’s for healthier cooking or ease of clean up (they’re dishwasher safe!), whichever pack you choose we just know you’ll be thrilled with your new non-warping stainless steel baking sheets.
