Creating Biscuits and Gravy Breakfast Casserole is a straightforward process when you follow these steps:

1. Preheat the Oven: Start by preheating your oven to 375°F (190°C). This is essential for ensuring even baking.
2. Cook the Sausage: In a large skillet over medium heat, brown the breakfast sausage until fully cooked. Crumble the sausage as you cook, ensuring it is evenly browned.
3. Make the Gravy: Once the sausage is cooked, sprinkle the flour over it and stir for about 1 minute to combine. Gradually add the milk, stirring constantly until the mixture thickens, around 5-7 minutes. Season with garlic powder, onion powder, salt, and pepper. Remove from heat.
4. Prepare the Biscuits: Open the can of biscuits and cut each biscuit into quarters. Place the biscuit pieces in a greased 9×13 inch baking dish.
5. Layer the Casserole: Pour the prepared sausage gravy evenly over the biscuit pieces in the baking dish. Make sure to cover all pieces well.
6. Whisk the Eggs: In a separate bowl, whisk together the eggs and a dash of salt and pepper. Pour the egg mixture over the casserole.
7. Add Cheese: Sprinkle shredded cheddar cheese evenly on top of the casserole.
8. Bake: Place the casserole in the preheated oven and bake for 30-35 minutes, or until the eggs are set and the cheese is bubbly and golden brown.
9. Rest Before Serving: Remove from the oven and allow it to rest for about 10 minutes so it can firm up slightly.
10. Garnish: If desired, sprinkle chopped chives or parsley over the top for added flavor and presentation.
