A baking tray, also known as a baking sheet, is a flat, rectangular metal pan used in ovens for baking various foods. It typically has low sides, allowing for easy access to the food and even heat distribution. Baking trays come in different sizes and materials, such as aluminum or stainless steel, and are often coated with non-stick surfaces for easier food release. These trays are commonly used for baking items like cookies, pastries, and roasted vegetables. They can also be used for broiling or to catch drips from other dishes. Proper care, such as avoiding metal utensils on non-stick surfaces, can extend the life of a baking tray.
