I often come across Facebook posts about cookware to avoid and what to replace it with, sometimes including lists of other kitchen items to stop using. Aluminum foil is often mentioned, but I’ve rarely seen suggestions for alternatives.

A few weeks ago, while making lasagna, I realized I was out of aluminum foil right when it was time to bake. Since lasagna needs to be covered while baking and I didn’t feel like running to the store, I searched my kitchen for a replacement. I spotted a freshly washed cookie sheet in the drying rack, and it fit perfectly over my lasagna pan. I baked it like that, and it turned out great. Since then, I’ve been using a cookie sheet as a cover for dishes that need to go in the oven.
