Frequent question: How do I keep my baking sheet from warping?

So remember, to help stop your baking sheet from warping in the oven, cover the pan’s entire surface with food as uniformly as possible, and heat the pan slowly and gradually rather than abruptly.

Why do my baking sheets keep warping?

In the case of your metal baking sheets and pans, multiple surfaces need to expand — the bottom of the pan or sheet and the four raised edges along its perimeter. As they heat up, they don’t all expand at the same rate. The bottom will expand slightly more than the raised lip. This creates stress at the folded edges.

Are there baking sheets that don’t warp?

Aluminum baking sheets are classics in the kitchen. While some are cheap and flimsy, these are commercial grade, so they’re heavier weight, and much more sturdy. For even better performance, they have rolled, encapsulated steel rims so they won’t bend or warp in normal use, and they’ll never rust or corrode.

When should I replace my baking sheets?

Any major dents or cracks in the pan are signs that you should replace your baking sheet. The dents and cracks cause uneven cooking with your food, making it frustrating to prevent undercooking or overcooking.
