Can you make biscuit and gravy casserole ahead of time?

Yes, and it turns out great! Assemble everything the night before and bake in the morning. Just allow extra bake time if it's cold from the fridge.

How do you know when a breakfast casserole is done?

It’s ready when the eggs are set (not jiggly) and the top is golden. A knife inserted in the center should come out clean.

A flavorful sausage, well-seasoned gravy, and a good biscuit-to-egg ratio. Fresh herbs or a sprinkle of cheese also go a long way.

They’ll keep for up to 3 days in the fridge. Reheat gently in the oven or microwave until warmed through.

A one-pan Southern-style breakfast casserole combining biscuits, sausage, eggs, cheese, and gravy. Ideal for holidays, brunches, or meal prep.
