FAQ:
How to serve:
Some of my favorite sides to serve with this casserole are home fries, toast, fresh fruit salad, mixed green salad, and roasted vegetables.
How to reheat:
Preheat the oven to 350F. Place the desired portion in a baking dish and cover it with aluminum foil to prevent it from drying out. Reheat for about 15-20 minutes or until heated through. For individual portions, microwave for about 1 minute.
Can I make breakfast casserole 2 days ahead?
You can, but just note that the bread breaks down more the longer it sits, so the texture will be softer.
Can you freeze breakfast casserole?
Baked casserole may be frozen for up to 2 months. Thaw in the refrigerator overnight and bake at 350F for about 20 minutes or until heated through.
You can also freeze unbaked casserole for up to 2 months. Cover very tightly with plastic wrap and foil. Thaw overnight in the refrigerator and bake as instructed.
