Can I make this casserole ahead of time?

Yes! You can assemble the casserole the night before, cover it, and store it in the refrigerator. In the morning, simply uncover and bake as directed. It’s a great option for holidays, brunch parties, or busy mornings when you want to have breakfast ready to go with minimal effort.

Can I use fresh potatoes instead of tater tots?

You can! Shredded or cubed fresh potatoes can be used, but they may need to be par-cooked first so they soften fully while baking. Tater tots give a crispier finish, but fresh potatoes offer a more homemade feel. Make sure to season them well.

Can I freeze individual servings?

Absolutely. Once the casserole is baked and cooled, slice it into portions, wrap them individually, and store them in freezer bags or containers. They reheat well in the microwave or toaster oven, making them perfect for meal prep or busy mornings.

Notes

How to store: Store leftovers in an airtight container in the fridge for up to 4 days.

How to reheat: To reheat, place a slice of casserole on a microwave-safe plate and heat for 1–2 minutes until warmed through. For larger portions or crisper edges, reheat in a 350ºF oven or air fryer for 10–15 minutes. Cover with foil if needed to prevent over-browning. Avoid overheating to preserve the creamy texture.

How to freeze: Bake the casserole, let it cool completely, and then cover tightly with foil or plastic wrap. Freeze for up to 2 months. Thaw overnight in the fridge and reheat. You can also freeze individual portions for easy grab-and-go breakfasts.
