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 rich flavor to the casserole.
- Layer Eggs and Sausage: Arrange the sliced hard-boiled eggs evenly on the bottom of the prepared baking dish. Spread the cooked and crumbled breakfast sausage evenly over the eggs to form the base layer.
- Mix Creamy Sauce: In a mixing bowl, whisk together milk, heavy cream, mustard powder, salt, black pepper, garlic powder, and onion powder until fully combined, creating a flavorful custard-like mixture.
- Assemble Casserole: Pour the milk and cream mixture evenly over the layered eggs and sausage in the baking dish. Sprinkle the shredded Cheddar cheese evenly on top to cover the entire surface.
- Add Butter Dots: Cut the butter into small pieces and dot them over the top of the casserole. This will help form a golden, buttery crust when baked.
- Bake: Place the casserole in the preheated oven and bake for 25-30 minutes or until the casserole is bubbly throughout and the top is golden and slightly crisp. Remove from oven and let it rest briefly before serving.
Notes
- You can substitute the breakfast sausage with cooked bacon or turkey sausage for a different flavor.
- For a spicier kick, add some crushed red pepper flakes to the creamy sauce mixture.
- Make sure the eggs are fully hard-boiled to prevent any runny texture in the casserole.
- This casserole can be prepared the night before; just assemble, cover, and refrigerate, then bake in the morning.
- Leftovers can be stored in an airtight container in the refrigerator for up to 3 days and reheated in the oven or microwave.
