How to store: I like to keep casseroles in the same dish I make them in. After cooling, wrap your casserole in plastic cling wrap and store it in the refrigerator for up to four days. You can also transfer and store in an airtight container. Most of these casseroles can also be frozen for up to 3 months. Check the individual recipe for full storing instructions.

How to reheat: The best way to reheat a casserole is in the oven at 350F for 15-30 minutes (depending on the size of your meal). Wrap it loosely in aluminum foil before baking.

Microwave instructions: You can also reheat a couple servings of the leftover casserole in the microwave if you’re in a hurry. Heat in a covered microwave-safe dish for 2-5 minutes on medium-low heat.
