How to Make Hard-Boiled Egg and Sausage Breakfast Casserole Recipe
Step 1: Prepare Your Baking Dish
Start by preheating your oven to 350 degrees Fahrenheit (175°C). Generously butter a 9×13-inch baking dish to prevent sticking while adding richness to the crust. This step ensures that your casserole will release effortlessly once baked.
Step 2: Layer Eggs and Sausage
Next, arrange the sliced hard-boiled eggs evenly across the bottom of your greased dish. Follow this with a layer of the cooked and crumbled breakfast sausage, spreading it so each bite will deliver both flavors.
Step 3: Whisk the Creamy Mixture
In a mixing bowl, combine the milk, heavy cream, mustard powder, salt, black pepper, garlic powder, and onion powder. Whisk until everything is fully integrated, creating a smooth custard that will soak into the eggs and sausage.
Step 4: Assemble and Top with Cheese
Pour the seasoned milk and cream mixture evenly over your layered eggs and sausage. Then sprinkle the shredded cheddar cheese evenly on top. This forms a gorgeous cheesy layer that bakes into a golden, decadent crust.
Step 5: Butter Dotting
Dot the top of the casserole with small pieces of butter. Butter melting during baking helps develop a beautifully golden and slightly crispy surface.
Step 6: Bake to Perfection
Bake the casserole in the preheated oven for 25 to 30 minutes. You’ll know it’s ready when the top is bubbly and golden, and the custard is set but still moist and luxurious. Let it cool slightly before serving.

FAQs
