How should I store leftover hashbrown casserole breakfast?
Leftover hashbrown casserole should be stored in an airtight container in the refrigerator. It will stay fresh for up to 3-4 days. When reheating, you can use the microwave, but for the best results, reheat in the oven at 350°F (175°C) until warmed through. That way you retain the crispiness winning!

While delicious, this casserole is definitely a treat. You can lighten it up by using reduced fat cheese, lean breakfast sausage, and adding more vegetables. The calorie count really depends on the ingredients you use, so always check the labels if you're counting.
