Ingredients

Scale

Biscuits

1 (16 oz) can refrigerated buttermilk biscuits (8-count)

Sausage Gravy

1 lb breakfast sausage (pork or turkey)
¼ cup all-purpose flour
2 ½ cups whole milk
½ teaspoon salt
¼ teaspoon black pepper

Egg Mixture

6 large eggs
½ cup milk
½ teaspoon salt
¼ teaspoon black pepper
1 cup shredded cheddar cheese (optional)

Other

Nonstick cooking spray

Instructions

Preheat the Oven: Preheat your oven to 350°F (175°C). Spray a 9×13-inch baking dish with nonstick cooking spray to prevent sticking.
Cook the Sausage: In a large skillet over medium heat, cook the breakfast sausage until it is browned and fully cooked through. Do not drain the fat as it will be used to make the gravy.
Make the Gravy: Sprinkle the flour evenly over the cooked sausage and stir to coat the meat and fat. Slowly pour in the 2 ½ cups of whole milk while stirring constantly. Let the mixture simmer gently for 5–7 minutes until the gravy thickens and becomes creamy. Season with salt and pepper to taste, then remove from heat.
Cut the Biscuits: Cut each biscuit into quarters. Spread the biscuit pieces evenly across the bottom of the prepared baking dish.
Assemble the Casserole: Pour the warm sausage gravy evenly over the biscuits. In a separate bowl, whisk together the eggs, ½ cup of milk, salt, and pepper. Stir in the shredded cheddar cheese if using. Pour this egg mixture evenly over the gravy and biscuit layers in the baking dish.
Bake: Bake the casserole uncovered in the preheated oven for 35 to 40 minutes or until the eggs are fully set, the biscuits are cooked through, and the top is golden and bubbly. Be careful not to overbake to maintain a soft, fluffy texture.
Cool and Serve: Allow the casserole to rest for 5–10 minutes after baking. This helps it set and makes it easier to slice. Serve warm and enjoy your comforting Southern breakfast casserole.

Notes

This casserole can be assembled the night before; cover tightly with foil and refrigerate. Bake fresh in the morning for convenience.
You can freeze leftovers wrapped tightly for up to 2 months; reheat in the oven at 325°F until heated through.
If using homemade biscuits, consider pre-baking or par-baking them slightly before layering to ensure proper baking.
For an extra kick, use spicy breakfast sausage or add diced jalapeños to the egg mixture.
Add sautéed vegetables like onions, bell peppers, or mushrooms for added flavor and nutrition.
Top individual servings with hot sauce or a drizzle of maple syrup for a sweet-savory contrast.
Leftovers can be stored in an airtight container in the refrigerator for up to 4 days.
