Yes, you can use aluminum foil facing for baking. It's a common practice to line baking sheets with aluminum foil to prevent food from sticking and to make cleanup easier. However, ensure the foil does not come into direct contact with the heating elements of the oven as it can melt. Additionally, avoid wrapping food in aluminum foil for extended baking times at high temperatures, as it may lead to uneven cooking or potential health concerns from aluminum leaching into the food.
