Equipment

  • 9×13-inch baking dish
  • Large skillet
  • Mixing bowls
  • Whisk
  • Measuring cups and spoons
  • knife
  • Cutting board
  • Wooden spoon or spatula

Ingredients

Biscuit Layer

  • 1 16 oz can refrigerated biscuits, cut into 1-inch pieces

Sausage Gravy

  • 1 lb breakfast sausage pork or turkey
  • ¼ cup all-purpose flour
  • 2 ½ cups whole milk
  • ½ tsp salt
  • ½ tsp black pepper
  • ¼ tsp garlic powder optional
  • Pinch of cayenne optional
  • Egg Custard
  • 6 large eggs
  • ½ cup whole milk or heavy cream
  • ½ tsp salt
  • ¼ tsp black pepper

Optional Toppings

  • ½–1 cup shredded cheddar cheese
  • Chopped parsley or chives for garnish

Instructions

  • Preheat oven to 350°F (175°C). Grease a 9×13-inch baking dish.
  • Brown the sausage in a large skillet over medium heat until fully cooked. Do not drain.
  • Make the gravy: Sprinkle flour over the sausage, stir, and cook 1 minute. Slowly whisk in milk. Simmer 5–7 minutes until thick. Season with salt, pepper, garlic powder, and cayenne.
  • Layer biscuits evenly in the prepared baking dish.
  • Pour sausage gravy over biscuit pieces, gently spreading to coat.
  • Whisk eggs, milk, salt, and pepper together, then pour evenly over the casserole.
  • Top with cheese if using.
  • Bake uncovered for 35–40 minutes, until puffed, golden, and set in the center.
  • Rest 10 minutes before slicing. Garnish if desired.

Notes

  • Use classic breakfast sausage for traditional flavor; spicy sausage adds a nice kick without extra seasoning.
  • Whole milk makes a balanced gravy, while heavy cream creates an extra-rich, indulgent texture.
  • Cut biscuit pieces evenly so they bake through at the same rate.
  • For a crispier top, sprinkle cheese on during the last 10 minutes of baking.
  • If the center browns too quickly, loosely tent with foil and continue baking until set.
  • Let the casserole rest 10 minutes before slicing so it holds together cleanly.
  • This casserole reheats well and is ideal for make-ahead breakfasts or brunch gatherings.
