Ingredients

1 can refrigerated biscuits, about 16 ounces
1 pound breakfast sausage
3 tablespoons all-purpose flour
2 1/2 cups whole milk
1/2 teaspoon black pepper
1/4 teaspoon garlic powder
1/4 teaspoon salt, or to taste
8 large eggs
1/2 cup milk
1 1/2 cups shredded cheddar cheese
2 tablespoons sliced green onions, optional for garnish

Biscuits and Gravy Breakfast Casserole Instructions

Preheat the oven to 350°F. Lightly grease a 9×13-inch baking dish.
Cut each biscuit into quarters and spread the biscuit pieces evenly across the bottom of the baking dish.
In a large skillet over medium heat, cook the breakfast sausage until browned and fully cooked, breaking it into crumbles as it cooks.
Remove about half of the cooked sausage and set it aside.
Leave the remaining sausage in the skillet. Sprinkle the flour over it and stir for about 1 minute.
Slowly pour in the 2 1/2 cups milk, stirring constantly.
Add black pepper, garlic powder, and salt.
Cook the gravy over medium heat for about 4–6 minutes, stirring frequently, until thickened.
Sprinkle the reserved sausage over the biscuit pieces.
In a medium bowl, whisk together the eggs and 1/2 cup milk.
Pour the egg mixture evenly over the biscuits and sausage.
Spoon the sausage gravy evenly over the top.
Sprinkle the cheddar cheese over the casserole.
Bake uncovered for 40–45 minutes, or until the eggs are set, the biscuits are cooked through, and the top is lightly golden.
Let the casserole rest for about 10 minutes before slicing.
Garnish with sliced green onions, if desired, and serve warm.

How to Know When It’s Done

The center should be set and no longer look wet or loose.

The biscuits should be fully baked with no raw or doughy centers.

If needed, insert a knife into the center to check that the biscuit layer is cooked through.

Tips for the Best Biscuits and Gravy Casserole

Cut the biscuits into quarters so they bake evenly.
Don’t make the gravy too thick on the stovetop; it will continue to thicken while baking.
Use a flavorful breakfast sausage because it provides most of the seasoning.
Shred your own cheese if possible for smoother melting.
Let the casserole rest before slicing so the layers can set.

Make-Ahead Option

For best results, prepare the sausage and gravy the night before and refrigerate them separately.

In the morning, assemble the casserole with fresh biscuit dough and the egg mixture, then bake.

This helps prevent the biscuits from becoming overly soft while sitting overnight.

Storage

Store leftovers in an airtight container in the refrigerator for up to 3–4 days.

Reheating

Reheat individual portions in the microwave until hot.

For several servings, cover loosely with foil and warm in a 325°F oven until heated through.

Freezing

Let the baked casserole cool completely.

Wrap tightly or portion into freezer-safe containers and freeze for up to 2 months.

Thaw overnight in the refrigerator before reheating.
