Yes, you can use aluminum foil to make pizza crusts. While it's not the traditional method, it can be a convenient alternative, especially when you don't have a pizza stone or baking sheet. Simply roll out your pizza dough on a lightly floured piece of aluminum foil, transfer it to a preheated oven, and bake as usual. The foil will help prevent the crust from sticking and can also make cleanup easier. However, for a crispier crust, you might still prefer using a pizza stone or baking sheet.
