FAQs

Do you cook sausage before adding it to a breakfast casserole?

Yes, sausage should always be browned in a skillet and drained of excess grease before adding it to the casserole. This prevents the dish from becoming greasy and ensures the meat is fully cooked.

Can I make a sausage and egg casserole ahead of time?

Yes, you can assemble the casserole the night before, cover it tightly, and refrigerate. Bake it in the morning, adding 5–10 extra minutes since it starts cold.

How do you know when a sausage and egg breakfast casserole is done?

The casserole is ready when the eggs are fully set, the cheese is melted, and the top is golden brown. A knife inserted into the center should come out clean.
