Ingredients

Scale
  • 1 can (16 oz) refrigerated biscuit dough (or 8 homemade biscuits, cut into quarters)
  • 1 pound breakfast sausage (pork, turkey, or chicken)
  • 1/4 cup all-purpose flour
  • 2 cups whole milk (or low-fat/non-dairy alternative)
  • 1/2 teaspoon black pepper
  • 1/4 teaspoon salt
  • 6 large eggs
  • 1/2 cup milk or half-and-half
  • 1 1/2 cups shredded cheddar cheese (divided)
  • 1/4 teaspoon garlic powder (optional)
  • 1/4 teaspoon smoked paprika (optional)
  • Chopped fresh chives or parsley (optional, for garnish)
  • 1/2 cup sautéed onions or bell peppers (optional)
  • Crumbled cooked bacon (optional)

Instructions

  1. Preheat oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with cooking spray or butter.
  2. Cut each biscuit into quarters and scatter evenly in the bottom of the prepared baking dish.
  3. In a large skillet over medium heat, crumble and cook the sausage until browned and cooked through (about 6-8 minutes). Drain excess fat, leaving about 1 tablespoon.
  4. Sprinkle flour over the cooked sausage, stirring to coat. Cook for 1-2 minutes. Gradually pour in 2 cups milk, whisking constantly. Cook, stirring, until thickened (about 3-5 minutes). Season with black pepper and salt.
  5. Pour sausage gravy evenly over biscuit pieces in the baking dish. Add optional sautéed veggies or bacon if desired.
  6. In a medium bowl, whisk together eggs, 1/2 cup milk or half-and-half, garlic powder, and smoked paprika (if using). Stir in 1 cup shredded cheddar cheese.
  7. Pour egg mixture evenly over the casserole. Sprinkle remaining 1/2 cup cheddar cheese on top.
  8. Bake for 35-40 minutes, or until eggs are set, biscuits are golden, and cheese is melted and slightly browned. If top browns too quickly, cover loosely with foil for the last 10 minutes.
  9. Let casserole rest for 10 minutes before slicing. Garnish with chopped chives or parsley if desired.

Notes

For gluten-free, use gluten-free biscuit dough and flour. Let the casserole rest before slicing for best texture. Add veggies or bacon for extra flavor. Can be assembled the night before and baked in the morning (add 10 minutes to bake time if cold). Leftovers reheat well and can be frozen for up to 2 months.
