Can I use aluminum foil facing to make a casserole dish cover?

Yes, you can use aluminum foil as a cover for a casserole dish. It's a common practice to cover the dish with foil to prevent the top from drying out during baking or to keep the contents warm. Ensure the foil is food-grade and does not touch the heating elements of the oven. For best results, use heavy-duty aluminum foil to avoid punctures and tearing. Remember to remove the foil during the last few minutes of baking to allow the top to brown if desired.
