Here’s how to make your Biscuits and Gravy Breakfast Casserole:

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Cook Sausage: In a large skillet, over medium heat, cook the sausage until fully browned. Break it apart as it cooks so that it crumbles.
3. Make Gravy: Sprinkle flour over cooked sausage and mix well. Slowly add milk, stirring constantly until the mixture thickens, about 5 minutes. Remove from heat.
4. Prepare Dish: Grease a 9×13-inch baking dish.
5. Layer Biscuits: Cut each biscuit into quarters and evenly distribute them across the bottom of the prepared dish.
6. Add Sausage: Pour the sausage gravy evenly over the biscuit pieces.
7. Whisk Eggs: In a separate bowl, whisk the eggs, garlic powder, onion powder, salt, and pepper until well combined.
8. Combine with Cheese: Pour the egg mixture over the biscuits and sausage. Sprinkle shredded cheddar cheese on top.
9. Bake: Place the casserole in the preheated oven and bake for 30-35 minutes or until the eggs set and the biscuits are golden.
10. Cool & Serve: Let the casserole cool for a few minutes before slicing. If desired, garnish with chopped parsley for a pop of color.

With these straightforward steps, you’ll be able to create a Biscuits and Gravy Breakfast Casserole that is sure to be a hit!
