Sausage Breakfast Casserole

My mother-in-law made me this breakfast casserole years ago and it’s my go-to favorite.  I love all breakfast casseroles but I continue to come back to this one because it’s so simple, you make it the night before and bake it in the morning.  And it’s always, always, always delicious.  Enjoy!
Shopping List
1 package Owen’s sausage, the Sage flavored is my favorite!
1 box Texas Toast croutons (I use the Caesar flavored ones)
6 eggs beaten
2 cups milk
1 can cream of mushroom soup
1 tablespoon mustard powder
2 cups cheddar cheese, divided
Brown sausage over medium-high heat until cooked through and crumbled.  Meanwhile, combine eggs, milk, soup, mustard and one cup of cheese in a bowl.  In a 9×13 inch pan, layer cooked sausage across bottom, then layer your box of croutons.  Next, pour egg mixture over.  Finally, top with remaining one cup of cheese.  Cover and refrigerate over night.
The next morning, bake casserole uncovered in a 350 degree oven for one hour.
So simple, right?!  And who says this has to be just for breakfast?  I could totally eat this as a weekday supper. Enjoy!

    I'm not a fan of mustard. Does this have a strong mustard flavor? would it be just as good without?

    You can totally leave it out! It will still be delicious!

    Quick question! I'm from Canada and not sure I've ever seen Texas croutons at the store before…..is there anything else I can substitute these for? Thx!

    Made this last night, baked this morning…sooo good!! I've made breakfast casserole numerous times before, but usually with plain bread. The croutons made it so simple and added a little kick of flavor! It's a keeper! Next up on my breakfast list…Pumpkin Cinnamon Rolls!! Thanks for the recipes šŸ™‚

    If I want to cook it the same day I prepare it, how long is the cooking time?

  • Mix and Match Mama October 25, 2014 at 8:23 pm

    The same amount of time! Enjoy!!

    I grew up eating this! My grandma makes it with stale bread cubed. I've made it even with fresh cubed bread (and Italian or French bread loaf gives nice crunchy pieces). Just thought I would share in case you don't want to make a special trip for croutons! šŸ™‚
