Can I make this casserole the night before?
Yes. Assemble the casserole, cover tightly with foil, and refrigerate overnight. Bake as directed, adding 5–10 minutes to the bake time if starting from cold.
What temperature should I bake this at?
Bake at 350°F (175°C) until the eggs are set and the top is lightly golden, typically 30–40 minutes.
Can I use fresh country gravy instead of a packet mix?
Yes. Make 2 cups of fresh country gravy from scratch (sausage drippings, flour, milk, salt, and pepper) and pour it over the layers before baking.
How do I know when the casserole is done?
Insert a knife near the center; it should come out clean with no wet egg. The top should be set and light golden brown.
Can I freeze leftovers?
Yes. Cool completely, cover tightly with foil, and freeze for up to 3 months. Reheat covered in a 350°F oven for 20–25 minutes until warmed through.
