Can Egg Casserole Be Frozen
Yes, egg casserole can be frozen for later use.
To freeze before baking, assemble the casserole, cover it tightly with plastic wrap and aluminum foil, and store it in the freezer for up to 2–3 months.
When you’re ready to bake, simply thaw it in the refrigerator overnight before cooking.
If freezing after baking, allow the casserole to cool completely, then portion it if desired and wrap it tightly or store it in airtight containers.

You can reheat the casserole directly from frozen or after thawing in the refrigerator, ensuring that the flavor and texture are preserved.

This makes egg casserole a convenient option for meal prep.
How To Reheat Egg Casserole
To reheat an egg casserole, the best method is to use the oven for even heating.
Preheat your oven to 350°F (175°C) and place the casserole in an oven-safe dish if it’s not already in one.
Cover the dish with aluminum foil to prevent it from drying out, and heat for 20-25 minutes, or until it’s heated through.
To check, insert a knife into the center; it should come out hot.
Alternatively, you can use the microwave for a quicker option.

Place a portion of the casserole on a microwave-safe plate and cover it with a microwave-safe lid or a damp paper towel to retain moisture.

Microwave on medium heat for 1-2 minutes, then stir if needed, and continue heating in 30-second intervals until the casserole is hot.
To avoid overcooking, be sure not to heat it too much, as this can cause the eggs to become rubbery.
