Classic Southern comfort food! This Biscuits and Gravy Casserole is an easy breakfast recipe or satisfying brunch that's perfect for entertaining!
Preheat oven to 400 degrees F. Spray a 3-quart baking dish with cooking spray and set aside.
Crumble the sausage in a skillet and cook over medium-high heat until no longer pink (about 5-7 minutes). Use a wooden spoon to break the sausage into small pieces as it cooks. Use a slotted spoon to remove the cooked sausage to a paper-towel lined plate. Leave no more than 1 tablespoon of fat drippings in the pan (discard any excess).
Bake casserole (uncovered) until the biscuit topping is golden brown and cooked through (about 15-20 minutes). Let the casserole stand for 5 minutes before serving.
