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 richness.
Layer eggs and sausage: Arrange the sliced hard-boiled eggs evenly across the bottom of the baking dish. Sprinkle the cooked and crumbled breakfast sausage over the egg layer, distributing it evenly.
Make custard mixture: In a medium bowl, whisk together the milk, heavy cream, mustard powder, salt, black pepper, garlic powder, and onion powder until well combined to create a flavorful custard base.
Assemble casserole: Pour the custard mixture evenly over the eggs and sausage in the baking dish. Then sprinkle the shredded Cheddar cheese generously on top to create a cheesy crust.
Add butter dots: Dot the surface of the casserole with small pieces of butter, which will melt and help the topping brown beautifully.
Bake: Place the dish in the preheated oven and bake for 25-30 minutes until the casserole is bubbly and the top is golden and slightly crispy. Remove from oven and let it cool slightly before serving.

Notes

You can substitute breakfast sausage with other cooked meats like bacon or ham for variation.
For a spicier kick, add a pinch of cayenne pepper or chili flakes to the custard mixture.
Make sure the eggs are peeled and sliced uniformly for even layering.
Leftovers can be refrigerated for up to 3 days and reheated in the oven or microwave.
This casserole freezes well; reheat thoroughly before serving.
