What's the difference between a frittata and an egg casserole?

Frittata: Cooked on the stovetop and finished in the oven, a frittata is like an open-faced omelet. It's usually cooked in a skillet and doesn't involve layering ingredients like a casserole.
Egg Casserole: A casserole typically has the ingredients mixed or layered in a baking dish and is baked in the oven.

When baking a casserole is it covered or uncovered?

Whether to bake this sausage and egg casserole covered or uncovered depends on your preferences.
Uncovered: Allows the top to brown and get a little bit crisp. If the top browns too quickly, cover it with foil until the casserole is cooked through.
Covered: Helps retain moisture and prevents excessive browning. Remove the cover toward the end to allow browning if needed.
