Đúng, aluminum foil can be used instead of a baking sheet, the main reason for using aluminum foil instead of a baking sheet is that it provides a temporary baking solution.
1. Sự dẫn nhiệt: aluminum foil can conduct heat, transfer heat to food, make it baked or baked. Although aluminum foil doesn’t conduct heat as evenly as a grill pan, it’s usually adequate for some simple baked goods, like toasting bread or roasting vegetables.

2. Isolation and anti-sticking: Aluminum foil can provide a layer of isolation between food and the oven, preventing food from sticking to the oven rack and reducing the trouble of cleaning. Using grease or cooking spray can further reduce the risk of food sticking.

3. Convenience: Aluminum foil is often a commonly available option when no bakeware is available. It spreads quickly on the oven rack and is conveniently discarded after use, reducing clean-up.

It should be noted that aluminum foil is relatively thin, less stable, and may not be strong enough for heavy or liquid foods. In these cases, it’s best to use a sturdy bakeware for safety and stability. Ngoài ra, using aluminum foil instead of a baking tray for a long time or frequently may cause the aluminum foil to crack or be damaged, so it is recommended to use a dedicated baking tray as much as possible.
