What to Serve With Breakfast Sausage Casserole

This breakfast sausage casserole is pretty filling on its own, so you don't need to worry about any sides. But, if you like having extra options at your table, then you can serve it alongside a light side, like fresh fruit or yogurt.

How to Store Breakfast Sausage Casserole

Store any leftovers in the fridge for up to five days. Reheat in the microwave or oven until warmed through.

How to Freeze Breakfast Sausage Casserole

This casserole is a great freezer meal. Wrap the baked casserole (dish and all) in a layer of storage wrap then a layer of aluminum foil. You may want to use a disposable casserole dish for easy freezing — or freeze the casserole in individual portions in zip-top freezer bags.

Freeze for up to three months. Defrost in the fridge overnight, then bake in the oven until warmed through.

"My family loves this and the casserole has now become a traditional menu item for Christmas morning...I used Jimmy Dean's hot sausage to give it some spice," raves justcookin.

"My kids don't like too many different ingredients, so I chose this recipe for the simplicity of what goes in it. It was a hit! Not too often do I get all three kids to eat what I make from scratch (I'm a great cook, just weird kids), but everyone went back for second helpings," according to Angie Frederick.

"OK, so I'm not a big egg casserole fan...but this was really really good! It was so easy, the only change I made was to use 6 eggs and did not add the dry mustard. Assembled the night before and just popped it in the oven that morning. Looking forward to making it again. GREAT RECIPE," says 2010.
