While aluminum foil is not a typical substitute for pie crust dough, it can be used in a pinch for a makeshift pie crust. However, it lacks the texture and taste of a traditional crust and may not be suitable for baking as it can buckle or tear easily. For a better result, it's recommended to use a proper pie crust recipe or a store-bought crust. Aluminum foil is better suited for lining baking sheets or covering dishes to prevent spills.
