Description

A hearty, one‑dish casserole layering sausage, fluffy eggs, and biscuits—perfect for a simple breakfast or brunch.


Ingredients

  • 1 lb breakfast sausage (bulk or patties, crumbled)
  • 6 large eggs
  • 1 cup milk
  • 1 tsp Dijon mustard or yellow mustard (optional)
  • 1/2 tsp salt
  • 1/4 tsp black pepper
  • 2 cups shredded cheddar cheese
  • 8 refrigerated biscuits (half‑sheet size, like Grands)
  • Optional: chopped scallions or parsley for garnish


Instructions

  1. Preheat oven to 375 °F (190 °C). Grease a 9×13‑inch baking dish.
  2. Cook sausage in a skillet over medium heat until browned and cooked through; drain excess fat.
  3. In a bowl, whisk together eggs, milk, mustard, salt, and pepper.
  4. Arrange biscuits in the prepared dish, either whole or halved to fit.
  5. Sprinkle cooked sausage evenly over the biscuits.
  6. Pour egg mixture over sausage and biscuits.
  7. Sprinkle cheddar cheese on top.
  8. Bake uncovered for 25–30 minutes until eggs are set and biscuits are golden.
  9. Let rest 5 minutes; garnish with scallions or parsley if desired.
  10. Cut into squares and serve warm.
  11. Store leftovers in an airtight container in the refrigerator for up to 3 days; reheat in the oven or microwave.

Notes

  • Use turkey sausage or plant‑based sausage for a lighter version.
  • Add diced bell peppers, onions, or jalapeños under the cheese for extra flavor.
  • Substitute Bisquick or homemade biscuit dough if preferred.
  • Make ahead: assemble in the dish, cover, and refrigerate overnight; bake in the morning (add about 5 extra minutes).
  • Top with hot sauce or salsa for a spicy twist.
