Almost nothing is as good as a breakfast casserole made from cheese, cream of mushroom soup, and hashbrowns. This childhood throwback is a Christmas morning tradition in so many households, and for good reason; it’s rich, and it’s comfort food galore, just like my baked pork chops with cream of mushroom soup

Sausage Breakfast Casserole

Stop, drop, and make this cheese-loaded mushroom and sausage breakfast casserole for Christmas morning, Christmas Eve morning, Boxing Day morning, or any fall or winter weekend morning. This is the perfect large casserole to feed a crowd for a holiday breakfast, and it’s so easy to make!

The Wife Saver Casserole

This is also called a Wife Saver casserole, a name I’ve come to love and hate. I love the retro awesomeness of the name, yet I cringe a little bit when reading it. It SHOULD be called a Husband Saver because it uses so few dishes during the preparation process, so Mr. Magpie doesn’t have that much to clean when I’m done. 😉

Make This Ahead of Time

If you want to make this the evening before, prepare it according to the instructions on the recipe card, cover and place it in the refrigerator until the following day. Then you take it from the fridge and bake it according to the instructions.

If you want to freeze it, you must bake it first, cool the casserole completely, and then wrap it in aluminum foil to freeze for up to 3 months. Then, when ready to eat, you can reheat it in the oven from frozen.

How to Make This Breakfast Casserole

This casserole is so very easy.

  1. Fry the sausage until fully cooked and drain all the fat.
  2. Combine the remaining ingredients in a bowl, mix in the sausage, then spoon into a greased 9×13 baking dish.
  3. Once you bake up that casserole until it bubbles, you get this creamy, gorgeous, rich breakfast casserole.

What to Serve With This Casserole

I said that this is a rich breakfast dish and I mean it! I would serve it with a fruit platter and a brown sugar fruit dip or cream cheese fruit dip! This will serve up to 12 people if you add in some fruit on the side.

Happy cooking everyone! Let me know in the comments below if you tried the recipe!

Love,
