This one-pan wonder turns the classic diner breakfast into an easy, hands-off casserole. Fluffy buttermilk biscuits soak up a creamy, peppery sausage gravy and bake with eggs and cheese into a golden, bubbling masterpiece. It’s the ultimate cozy dish for feeding a crowd on a lazy weekend or holiday brunch.

Ingredients

Scale
  • 1 pound breakfast sausage
  • 1/4 cup all-purpose flour
  • 3 cups whole milk
  • 1/2 teaspoon garlic powder
  • 1 teaspoon freshly cracked black pepper
  • 1/2 teaspoon salt, or to taste
  • 1 (16.3 oz) can refrigerated buttermilk biscuits (8 count)
  • 6 large eggs
  • 1/4 cup milk
  • 1 cup shredded sharp cheddar cheese
  • Optional garnish: chopped fresh parsley or chives

Instructions

  1. Preheat oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.
  2. In a large skillet over medium-high heat, cook sausage, breaking it up, until browned. Do not drain.
  3. Sprinkle flour over sausage. Stir constantly for 1-2 minutes.
  4. Slowly pour in the 3 cups of milk, whisking continuously. Add garlic powder, pepper, and salt. Simmer, stirring, until thickened into gravy, 5-7 minutes. Remove from heat.
  5. Pour sausage gravy into the prepared baking dish, spreading evenly.
  6. Cut each biscuit into 6-8 small pieces. Scatter pieces evenly over the gravy.
  7. In a bowl, whisk together eggs and 1/4 cup milk. Pour evenly over biscuit pieces.
  8. Sprinkle shredded cheese over the top.
  9. Bake for 30-35 minutes, until biscuits are golden, eggs are set, and cheese is bubbly.
  10. Let casserole rest for 5-10 minutes before serving.

Notes

For make-ahead, assemble, cover, and refrigerate overnight. Bake as directed, adding 5-10 minutes if cold. Do not drain sausage fat; it’s essential for the gravy. Add milk slowly to prevent lumps. Letting it rest ensures clean slices.
