Biscuits and Gravy Breakfast Casserole

This Biscuits and Gravy Breakfast Casserole is the ultimate morning comfort dish. By layering flaky biscuits with a rich, peppery sausage gravy and a savory egg custard, you create a hearty “all-in-one” meal that tastes like a cozy diner breakfast. The secret is the warm milk technique in the gravy; it ensures a silky smooth sauce that doesn’t clump, allowing the biscuits to absorb all that savory flavor without becoming soggy.

How To Make Biscuits and Gravy Breakfast Casserole:
Step 1: The Sausage Gravy Base: In a large skillet, brown the sausage over medium heat (5/7 mins). Keep about 2 tablespoons of the fat in the pan. Sprinkle the flour over the meat and stir for 2 minutes. Gradually whisk in the 3 cups of warm milk, then add the garlic powder, onion powder, thyme, salt, and pepper. Simmer for 3/5 minutes until thick.

Step 2: Assemble the Casserole: Preheat oven to 375°F. Grease a 9×13-inch dish. Arrange the biscuits in a single layer at the bottom (cut them in half if needed to cover the space). Pour the warm gravy evenly over the biscuits.

Step 3: The Egg Layer: Whisk the eggs, 1 cup of milk, salt, and pepper (plus a pinch of cayenne) until smooth. Pour this mixture gently over the gravy layer.
Tip: 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 4: Bake and Set: Bake for 35/45 minutes. The casserole is done when the eggs no longer jiggle in the center and the biscuits are a deep golden brown. Let the dish rest for 10 minutes—this is critical to let the eggs firm up so you can get clean slices.
Step 5: The Finishing Touch: Brush the top with melted butter and sprinkle with fresh chives.
