Introduction

The first time I made this biscuits and gravy breakfast casserole I woke up to the smell of sizzling sausage and warm biscuits filling the whole house. It began as a sleepy weekend experiment when I wanted something that tasted like my grandmother’s country gravy but fed a crowd without standing at the stove all morning. The first bite was all buttery biscuit, peppery sausage, and rich, creamy gravy that soaked into the eggs just enough to be custardy and comforting.

This recipe is a family favorite because it turns a classic Southern breakfast into a hands-off, oven-baked crowd-pleaser. It is perfect for lazy weekend brunches or holiday mornings, and it pairs well with simple sides like fresh fruit. If you like a hearty breakfast that warms you from the inside out, this will become a go-to. Also, if you enjoy casseroles with a twist, you might like this twist on a Tater Tot bake I sometimes pair with it: tater-tot breakfast casserole.

How to make Biscuits and Gravy Breakfast Casserole

Step 1: Preheat and prep

Preheat oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or nonstick spray.
Cook the sausage in a skillet over medium heat until browned and no longer pink, about 6 to 8 minutes. Drain excess fat and set sausage aside.

Step 2: Prepare biscuits or bread

Tear the canned biscuits into bite-sized pieces or cube day-old biscuits. Scatter the pieces evenly in the prepared baking dish so the base is covered.

Step 3: Make the gravy

In the same skillet over medium heat, melt 3 tablespoons butter. Sprinkle in 1/4 cup flour and whisk constantly for 1 to 2 minutes until lightly golden and fragrant.
Gradually whisk in 2 1/2 cups warm milk to avoid lumps. Continue whisking until the mixture thickens to a creamy gravy that coats the back of a spoon, about 4 to 6 minutes.
Season with 1/2 teaspoon salt, 1/4 teaspoon black pepper, and a pinch of cayenne if using. Taste and adjust seasoning.

Step 4: Assemble the casserole

Evenly distribute the cooked sausage over the biscuit pieces in the dish.
Crack the eggs into a medium bowl; add 2 cups milk, 1 teaspoon salt, 1/2 teaspoon pepper, and dried parsley. Whisk until combined.
Pour half of the gravy over the biscuit-sausage layer. Then pour the egg-milk mixture evenly over everything so biscuits absorb liquid.

Step 5: Bake

Cover the dish with foil and bake at 350°F (175°C) for 30 minutes. Remove foil and bake an additional 15 to 20 minutes, or until the eggs are set in the center and the top is golden and slightly puffed.
Visual cues: center should not be runny; a toothpick in the middle should come out mostly clean with a few moist crumbs.

Step 6: Rest and serve

Let the casserole rest for 10 minutes before slicing so it sets and is easier to serve.
Spoon remaining gravy warm over slices if desired.

Expert Tips & Ideas

Use room temperature eggs and milk so the custard bakes evenly and does not curdle.
Toast the torn biscuit pieces lightly in a 350°F oven for 5 minutes if they are very soft; this helps them hold texture when soaked.
If your gravy becomes too thick, whisk in an extra tablespoon or two of milk to reach the right pourable consistency.
Variations:
Vegetarian: substitute cooked crumbled vegetarian sausage and use vegetable stock with a dairy-free milk in the gravy.
Low-carb: replace biscuits with cauliflower mash or a low-carb biscuit alternative.
Cheesy: stir 1 to 1 1/2 cups shredded sharp cheddar into the egg mixture before baking.
To make ahead: assemble the casserole, cover, and refrigerate overnight. Bake the next morning, adding 10 to 15 minutes to the total bake time.
Storage and reheating: refrigerate leftovers in an airtight container for up to 4 days. Reheat single portions in the microwave for 1 to 2 minutes or in a 350°F oven until warmed through.

How to Serve

Serve slices with a drizzle of warm gravy on top and a sprinkle of chopped fresh parsley.
Pairings: fresh fruit salad, crispy hash browns, or a simple green salad for brunch. For drinks, offer coffee, orange juice, or a light mimosa.
Presentation tip: garnish with a few flaky sea salt crystals on top of each slice for a subtle crunch and enhanced flavor.
Nutrition note: approximate calories per serving depend on ingredient choices; using whole milk and regular sausage is richer while turkey sausage and 2% milk reduce calories.

Frequently Asked Questions

Q: Can I make this recipe ahead of time?

A: Yes, assemble the casserole, cover, and refrigerate overnight. Bake in the morning; you may need to add 10 to 15 minutes to the bake time if it is very cold.

Q: Can I freeze the leftovers?

A: You can freeze baked slices wrapped tightly for up to 2 months. Thaw overnight in the refrigerator before reheating in the oven or microwave.

Q: What can I use instead of canned biscuits?

A: Day-old biscuits, cubed fresh bread, or savory biscuit dough works well. For gluten-free, use GF biscuits or bread.

Q: How do I prevent the dish from becoming soggy?

A: Toasting the biscuit pieces briefly before assembling and using a slightly thicker gravy helps. Ensure the egg mixture is well balanced so biscuits absorb but do not dissolve.

Q: Can I make this vegetarian or dairy-free?

A: Yes. Use vegetarian sausage and substitute dairy-free milk and vegan butter, and thicken the gravy with a GF flour or cornstarch slurry if needed.
