Making Biscuits and Gravy Breakfast Casserole may appear daunting, but it’s quite simple if you follow these steps:

1. Preheat Oven: Begin by preheating your oven to 350°F (175°C).
2. Cook Sausage: In a large skillet over medium heat, crumble and cook the breakfast sausage until browned. Drain any excess fat and set aside.
3. Prepare Biscuits: Open the package of biscuits and cut each biscuit into quarters. Place them evenly in a greased 9×13-inch baking dish.
4. Mix Eggs and Spice: In a mixing bowl, whisk together the eggs, milk, garlic powder, onion powder, salt, and black pepper until well combined.
5. Combine Ingredients: Stir the cooked sausage and cheese into the egg mixture until evenly distributed.
6. Assemble Casserole: Pour the egg mixture over the biscuit pieces in the baking dish, ensuring all biscuits are coated.
7. Top with Soup: If using, spoon the cream of mushroom soup over the top for added flavor and creaminess.
8. Bake: Place the dish in the preheated oven and bake for 35-40 minutes, or until the casserole is set and lightly browned on top.
9. Cool: Allow the casserole to cool for about 5 minutes before slicing.
10. Garnish: Serve warm, garnishing with fresh parsley or chives for a pop of color.

By following these simple steps, you’ll have a warm and hearty Biscuits and Gravy Breakfast Casserole ready to serve.
