Notes

To Make Ahead - You can bake the sausage and hashbrown casserole right away or cover tightly and refrigerate it overnight. The next morning remove the baking dish from the refrigerator at least 30 minutes up to 1 hour before baking and follow the baking instructions.
Storing - Leftovers will keep in the fridge for 3-4 days. Reheat in the microwave or oven.
Freezing - Wrap individual servings tightly in plastic wrap or aluminum foil, and freeze in an air-tight container or freezer bag.
Or freeze the prepared unbaked casserole tightly wrapped in plastic wrap and then in aluminum foil for up to 3 months. Defrost in the refrigerator overnight, remove from the refrigerator for at least 30 minutes before baking and then bake as instructed.
