Ingredients
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
- 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.
- 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.
- 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.
- 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.
- 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.
- Bake: Place the casserole in the oven and bake for 30 minutes or until the casserole is bubbly throughout and the top is golden and slightly crisp.
Notes
- Use fully cooked breakfast sausage to ensure the dish is safely cooked through.
- Hard-boil the eggs a day ahead for easy assembly in the morning.
- For a lower-fat version, substitute heavy cream with additional milk or a milk alternative.
- Allow the casserole to rest for 5 minutes after baking to set before serving.
- Optional: Add chopped vegetables such as bell peppers or onions for extra flavor and nutrition.
