Storage/Reheating

Reheating: To reheat, simply cover the casserole with foil and warm it in a 350°F oven for about 15 minutes, or until heated through.

FAQs

How can I make this casserole ahead of time?

I can make this casserole the night before by assembling it in the baking dish, covering it with foil, and refrigerating it overnight. In the morning, I just need to bake it as usual.

Can I use fresh bread instead of day-old bread?

Yes, fresh bread works fine too, but day-old bread has a bit more texture and will soak up the egg mixture better without becoming too soggy.

Can I freeze this casserole?

Yes, this casserole can be frozen before baking. Just assemble it, cover tightly with plastic wrap and foil, and freeze for up to 3 months. When ready to bake, let it thaw overnight in the fridge and bake as directed.

How can I make this casserole spicier?

If I love a little heat, I can add some crushed red pepper flakes or a diced jalapeño to the egg mixture for a spicy kick.

Can I use a different type of milk?

Yes, I can substitute any kind of milk I prefer, including almond milk, oat milk, or even heavy cream for a richer texture.

This Grilled Cheese Breakfast Casserole is a game-changer for breakfast or brunch! With its layers of bread, cheese, and savory egg mixture, it’s the perfect balance of comfort and flavor.
