Eggs and milk: Whisked together and poured over the layers.
Dry mustard, salt and pepper: For seasoning. The dry mustard adds a little savory kick.

You’ll find the exact amounts and steps in the printable recipe card below.

How to Make It

Brown the sausage in a skillet, breaking it up as it cooks, and drain it well. Spread the thawed hash browns in a greased 9×13-inch baking dish, layer the sausage on top, and sprinkle the cheddar evenly over everything. Whisk the eggs, milk, dry mustard, salt and pepper together and pour it over the layers. Cover the dish and tuck it in the fridge overnight (or at least 4 hours). In the morning, bake it until it’s set in the center and golden on top, let it rest for 10 minutes, and serve.

Tips for the Best Christmas Morning Casserole

Drain the sausage well. Extra grease can make the casserole soggy.
Give it time to soak. Refrigerate it overnight, or at least 4 hours, before baking.
Use the right dish. A 9×13-inch baking dish with a lid makes chilling and baking easy.
Let it rest. Give it 10 minutes out of the oven so it slices neatly.
