How to Make Biscuits and Gravy Breakfast Casserole

1. Preheat Your Oven

Set your oven to 350°F (175°C). Grease a 9×13-inch baking dish generously to prevent sticking.

2. Cook the Sausage

In a large skillet over medium-high heat, cook the ground breakfast sausage until browned and no longer pink. Drain excess grease.

3. Make the Gravy

Reduce heat to medium. Sprinkle in 2 packets of gravy mix, then stir in 1 cup of evaporated milk and 1 cup of water. Simmer and stir until the mixture thickens to a gravy-like consistency.

4. Prepare the Eggs

In a mixing bowl, whisk together the 12 eggs, 5 oz. evaporated milk, and a pinch of salt and pepper. Lightly scramble the eggs in a skillet just until they’re set but still soft.

5. Layer the Casserole

Start layering in your greased dish:

Spread ⅓ of the sausage gravy on the bottom.
Add ½ of the scrambled eggs.
Repeat with another ⅓ of the gravy and the remaining eggs.
Top with the final layer of gravy.

6. Add the Biscuits

Place the refrigerated biscuits evenly on top of the layered casserole.

7. Bake

Bake uncovered for 20–25 minutes, or until the biscuits are golden brown and cooked through.

Let rest for 5 minutes before serving to allow layers to set.

Pro Tips for Perfect Results

Don’t overcook the eggs—they’ll continue cooking in the oven.
Use a deep casserole dish to avoid overflow.
Let the gravy thicken slightly before layering—it keeps the dish from being too runny.
For crispier biscuits, brush them with a bit of melted butter before baking.
Add cheese between layers for extra indulgence (sharp cheddar works great!).

Variations to Try

Cheesy Version: Sprinkle shredded cheese between the egg and gravy layers.
Spicy Kick: Use hot sausage and add a pinch of cayenne or crushed red pepper.
Vegetarian Twist: Skip the sausage and use plant-based meat alternatives or sautéed mushrooms and onions.
Make Ahead: Assemble the night before and bake in the morning—just add 5 extra minutes to bake time.

Fresh fruit salad or citrus wedges
A pot of hot coffee or sweet tea
Sliced avocado or tomato salad for a lighter balance

Storage & Reheating Tips

Refrigerate leftovers in an airtight container for up to 4 days.
Reheat individual servings in the microwave or oven at 350°F until warmed through.
