The Complete Recipe: Biscuits and Gravy Breakfast Casserole
Prep Time: 20 minutes | Cook Time:35-45 minutes | Total Time: 55-65 minutes | Servings: 8-10
Ingredients
The Layers:
-
1 (16.3 oz) can refrigerated buttermilk biscuits
-
1 lb breakfast sausage (mild or spicy)
-
8 large eggs
-
3 cups whole milk (for gravy)
-
1 cup whole milk or half-and-half(for eggs)
-
⅓ cup all-purpose flour
Seasonings and Toppings:
-
½ teaspoon garlic powder
-
½ teaspoon onion powder
-
½ teaspoon dried thyme
-
¾ teaspoon black pepper, divided
-
1 teaspoon salt, divided
-
2 tablespoons unsalted butter, melted
-
Optional: cheddar cheese, cayenne, chives
Step-by-Step Instructions
Step 1: Make the Sausage Gravy Base
In a large skillet, brown the sausage over medium heat for 5 to 7 minutes, breaking it into crumbles. Keep about 2 tablespoons of the rendered fat in the pan. Sprinkle the flour over the meat and stir for 2 minutes to cook out the raw flour taste.
Gradually whisk in the 3 cups of warm milk, then add the garlic powder, onion powder, thyme, ½ teaspoon salt, and ½ teaspoon pepper. Simmer for 3 to 5 minutes until thick and creamy. Set aside.
Step 2: Preheat and Prepare the Baking Dish
Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish.
Step 3: Layer the Biscuits
Arrange the refrigerated biscuits in a single layer at the bottom of the prepared dish. Cut them in half if needed to cover the space evenly.
Step 4: Add the Gravy
Pour the warm sausage gravy evenly over the biscuits, covering them completely.
Step 5: Prepare and Add the Egg Layer
In a medium bowl, whisk together the eggs, 1 cup of milk, remaining ½ teaspoon salt, remaining ¼ teaspoon pepper, and a pinch of cayenne if using until smooth.
Pour this mixture gently over the gravy layer. Important: Don’t stir the layers together! You want the egg mixture to sit on top and seep down naturally; this creates distinct textures of flaky biscuit, creamy gravy, and fluffy egg.
Step 6: Bake
Bake for 35 to 45 minutes. The casserole is done when the eggs no longer jiggle in the center and the biscuits are a deep golden brown.
Step 7: Rest and Finish
Let the dish rest for 10 minutes—this is critical to let the eggs firm up so you can get clean slices. Brush the top with melted butter and sprinkle with fresh chives or other optional toppings.
Step 8: Serve
Slice and serve warm.
