Easy Sausage Breakfast Casserole Recipe

Breakfast casseroles are a favorite in our house. We love them any time of the day – breakfast, lunch, and dinner. I am always coming up with new ways to make one of our favorite dishes. This Sausage Breakfast Casserole is different from most because it is made with croutons. Yep. The same croutons you throw on your salad are the base of this yummy casserole! I have to admit that I wasn’t sure how this would turn out, but it was DELICIOUS! It was so good, that we are making it again this week. YUM!

How to Make Overnight Sausage Crouton Breakfast Casserole

This casserole is super easy to make. It starts with cooking a pound of sausage. Once the sausage is cooked, drain the fat. Add the sausage, cheese, and croutons to a 9×13-inch dish. Whisk together eggs, milk, heavy cream, onion, dry mustard, salt, and pepper. Pour that over the sausage and crouton mixture.

Cover the casserole and let it sit in the refrigerator for at least an hour up to overnight. I love overnight breakfast casseroles! When you are ready to eat the casserole, take it out of the refrigerator and bake for 45 to 60 minutes. 

  • I used a roll of Jimmy Dean breakfast sausage. You can also use Tennessee Pride, Bob Evans, or even some Italian sausage.
  • For the croutons, I used Texas Toast croutons. I also like the Olive Garden croutons that are in the store. You can use any brand and flavor of croutons that you like. This recipe only uses a 5-oz bag of croutons. Resist adding more croutons. They expand as the casserole sits in the refrigerator. If you use a larger bag of croutons, it might be too much.
  • Can Sausage & Crouton Breakfast Casserole Be Frozen? Yes! This can be frozen baked or unbaked. I usually freeze casseroles like this unbaked.
  • To bake this casserole after freezing, thaw completely in the refrigerator and bake as directed below.
  • If freezing the baked casserole, thaw completely in the refrigerator and reheat in the microwave or covered in the oven.
