- Preheat Oven:
- Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish.
- Prepare Biscuits:
- Cut the refrigerated biscuits into quarters. If using homemade biscuits, cut them into bite-sized pieces.
- Cook Sausage:
- In a large skillet, cook the ground breakfast sausage over medium heat, breaking it up with a spoon as it cooks. Once browned, remove excess grease, leaving about 2 tablespoons in the skillet.
- Make Gravy:
- Sprinkle the flour over the cooked sausage and stir to combine. Cook for 1-2 minutes to get rid of the raw flour taste. Gradually whisk in the milk, stirring constantly to avoid lumps. Cook the gravy until it thickens, about 5 minutes. Season with salt and black pepper to taste.
- Assemble Casserole:
- In the prepared baking dish, spread half of the biscuit pieces. Pour half of the sausage gravy over the biscuits. Add the remaining biscuit pieces and top with the remaining sausage gravy.
- Whisk Eggs:
- In a bowl, whisk the eggs together. Pour the whisked eggs evenly over the biscuit and sausage layers.
- Add Cheese:
- Sprinkle shredded cheddar and mozzarella cheese over the top of the casserole.
- Bake:
- Bake in the preheated oven for 25-30 minutes or until the eggs are set and the cheese is melted and bubbly.
- Garnish and Serve:
- Garnish with chopped green onions or parsley if desired. Let it cool for a few minutes before slicing.
- Serve Warm:
- Serve the Biscuits and Gravy Breakfast Casserole warm and enjoy your delicious and satisfying breakfast!
