Description

This Hard-Boiled Egg Casserole is a hearty and comforting breakfast dish featuring layers of sliced hard-boiled eggs and savory breakfast sausage. Baked with a creamy mixture of milk, heavy cream, and seasonings, then topped with melted Cheddar cheese and butter, this casserole is perfect for a weekend brunch or a make-ahead meal that serves six.


Ingredients

Scale

Egg and Meat Layer

  • 8 hard-boiled eggs, peeled and sliced
  • 1/2 pound breakfast sausage, cooked and crumbled

Dairy and Seasonings

  • 1 cup shredded Cheddar cheese
  • 1/2 cup milk
  • 1/2 cup heavy cream
  • 1 teaspoon mustard powder
  • 1/2 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/4 teaspoon garlic powder
  • 1/4 teaspoon onion powder
  • 2 tablespoons butter


Instructions

  1. Preheat and Prepare Dish: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish thoroughly with butter to prevent sticking and add flavor.
  2. Layer Eggs and Sausage: Arrange the sliced hard-boiled eggs evenly on the bottom of the prepared baking dish. Then spread the cooked and crumbled breakfast sausage over the eggs to create a layered base.
  3. Mix Creamy Sauce: In a mixing bowl, whisk together the milk, heavy cream, mustard powder, salt, black pepper, garlic powder, and onion powder until fully combined to form a flavorful custard-like mixture.
  4. Assemble Casserole: Pour the milk and cream mixture evenly over the layered eggs and sausage in the dish. Next, sprinkle the shredded Cheddar cheese evenly on top to cover the surface.
  5. Add Butter Dots: Cut the butter into small pieces and dot the top of the casserole with these pieces to ensure a golden, buttery crust when baked.
  6. Bake: Place the casserole in the oven and bake for 25-30 minutes or until the casserole is bubbly throughout and the top is golden and slightly crisp.

Notes

  • For softer cooked sausage, avoid overcooking before assembling.
  • You can substitute Cheddar cheese with other cheeses like Monterey Jack or Swiss for different flavors.
  • This casserole can be prepared the night before and baked fresh in the morning for convenience.
  • Use a sharp knife to slice the hard-boiled eggs evenly for better layering.
  • Let the casserole cool slightly before serving to allow it to set for easier slicing.
