baking sheet

This term refers specifically to the flat, rimmed tray used for dry-heat cooking. While often used interchangeably with "cookie sheet," a baking sheet is generally considered a more versatile tool for roasting vegetables or baking various pastries, whereas a cookie sheet may be thinner or specifically designed for cookies.

In professional culinary contexts, these are often distinguished from "sheet pans," which are the heavy-duty, industrial versions used in commercial kitchens. Users should be aware that using parchment paper or silicone mats on a baking sheet is a common practice to prevent sticking and simplify cleanup.
