Ingredients

Scale

Biscuits

1 (16 oz) can refrigerated buttermilk biscuits (8-count)

Sausage Gravy

1 lb breakfast sausage (pork or turkey)
¼ cup all-purpose flour
2 ½ cups whole milk (for gravy)
½ teaspoon salt
¼ teaspoon black pepper

Egg Mixture

6 large eggs
½ cup milk (for eggs)
½ teaspoon salt (included above to season eggs and gravy)
¼ teaspoon black pepper (included above to season eggs and gravy)

Optional

1 cup shredded cheddar cheese (optional)
Nonstick cooking spray (for greasing the baking dish)

Instructions

Preheat the Oven: Preheat your oven to 350°F (175°C). Spray a 9×13-inch baking dish with nonstick cooking spray to prevent sticking.
Cook the Sausage: In a large skillet over medium heat, brown the breakfast sausage thoroughly until fully cooked. Do not drain the fat as it will be used to make the gravy.
Make the Gravy: Sprinkle the flour evenly over the cooked sausage and stir to coat the meat well. Slowly pour in 2 ½ cups of whole milk while stirring constantly to prevent lumps. Let the mixture simmer for 5–7 minutes until it thickens into a creamy gravy. Season with salt and pepper to taste, then remove from heat.
Cut the Biscuits: Cut each refrigerated biscuit into quarters and spread them evenly across the bottom of the prepared baking dish.
Assemble the Casserole: Pour the warm sausage gravy evenly over the biscuit pieces, coating them thoroughly. In a separate bowl, whisk together the eggs, ½ cup milk, salt, and pepper. If desired, stir in shredded cheddar cheese. Pour this egg mixture evenly over the top of the gravy and biscuits.
Bake: Place the casserole in the preheated oven and bake uncovered for 35–40 minutes until the eggs are fully set, the biscuits are cooked through, and the top is golden and bubbly.
Cool and Serve: Remove the casserole from the oven and let it rest for 5–10 minutes to set before slicing and serving warm.

Notes

This casserole can be assembled the night before and refrigerated; bake fresh the next morning for a stress-free breakfast.
Use spicy breakfast sausage for a flavorful kick.
Add sautéed vegetables like bell peppers, onions, or mushrooms for extra texture and nutrition.
Top with hot sauce or a drizzle of maple syrup to balance savory and sweet flavors.
Leftovers can be refrigerated in an airtight container for up to 4 days or frozen for longer storage.
If using homemade biscuits, pre-bake or par-bake slightly to ensure they cook fully in the casserole.
Do not overbake to maintain a soft, fluffy texture; begin checking at 35 minutes.
