Biscuits and Gravy Breakfast Casserole

This comforting dish takes the timeless Southern favorite of biscuits smothered in sausage gravy and elevates it into a complete, oven-baked meal. Packed with protein-rich sausage, fluffy eggs, melted cheese, and pillowy biscuit pieces, it’s a one-pan wonder that feeds a crowd effortlessly. Whether you’re hosting a holiday brunch or need a satisfying weekend breakfast, this recipe delivers bold flavors and simple preparation.

Why This Casserole Stands Out

Traditional biscuits and gravy require last-minute stove-top cooking, but this casserole version lets you assemble everything ahead and bake fresh. The biscuits absorb the savory gravy while staying tender, eggs set into a custardy layer, and sausage provides smoky depth. It’s versatile too—add veggies for nutrition or bacon for extra crunch. Families love it because it’s hearty enough to hold everyone over until lunch.

Essential Ingredients for Success

Gathering the right components ensures a balanced texture and taste. Here’s what you’ll need for a 9×13-inch dish serving 8-10:

• 1 pound breakfast sausage: Choose bulk pork sausage for its fat content, which flavors the gravy naturally.
• 1 can (8-count) refrigerated biscuit dough: Grands-style flaky biscuits work best for easy quartering.
• 6 large eggs: Provide structure and richness.
• 1/2 cup milk or heavy cream: Thins the eggs for even pouring.
• 2 cups shredded cheddar or Colby cheese: Melts creamy and adds sharpness.
• For homemade gravy: 1/3 cup butter, 1/3 cup flour, 3 cups milk, salt, pepper, onion powder.

Optional add-ins include crushed red pepper for heat, cooked bacon bits, or diced bell peppers for color and freshness.

Step-by-Step Assembly Guide

Prep time is about 20 minutes, with 30-45 minutes baking. Preheat your oven to 350°F and grease a 9×13-inch baking dish.

1. Brown the sausage: In a skillet over medium heat, cook 1 pound sausage until crumbled and no pink remains, about 8 minutes. Drain excess fat if needed, and stir in 1/4 teaspoon red pepper flakes for subtle spice. Set aside.
2. Prepare the gravy base: In the same skillet, melt 1/3 cup butter. Whisk in 1/3 cup flour to form a roux; cook 2 minutes. Gradually add 3 cups milk, whisking constantly. Season with 1/2 teaspoon salt, 1/2 teaspoon pepper, and 1/2 teaspoon onion powder. Simmer until thickened, 5-7 minutes. Mix in half the cooked sausage for integrated flavor.
3. Layer the biscuits: Quarter the biscuit dough and scatter evenly in the dish’s bottom. This creates a sturdy base that rises during baking.
4. Add proteins: Spread remaining sausage over biscuits, then sprinkle 1 cup cheese.
5. Pour egg mixture: Whisk eggs, milk, salt, and pepper. Drizzle over layers to soak through.
6. Finish with gravy and cheese: Pour gravy evenly, top with remaining cheese.
7. Bake uncovered: 30-40 minutes until biscuits puff, edges bubble, and eggs set. Center should reach 165°F internally.

Let rest 5-10 minutes before serving to allow layers to firm up.

Pro Tips for Perfect Results Every Time

• Gravy consistency: If too thick, thin with extra milk; it thickens more in the oven.
• Biscuit placement: Don’t press down—let them float for fluffiness.
• Cheese choice: Sharp cheddar cuts richness; mix with mozzarella for stretchiness.
• Make-ahead magic: Assemble without baking, cover, and refrigerate overnight. Add 10 minutes to bake time.
• Freezing option: Bake fully, cool, wrap, and freeze up to 2 months. Reheat at 350°F covered with foil.
