Father’s Day is approaching and I can’t think of any better breakfast for dads out there than this hearty Overnight Southwestern Breakfast Casserole!
This is actually one of my very first recipes from the archives that I wanted to resurrect because it’s one of my very favorite breakfast casseroles. It’s full of sausage, eggs, cheese, bread, mushrooms, onions and green peppers… you can also add seeded diced tomatoes or just about any other veggie you want.
I used cubed french bread but any cubed white bread will do. You’ll need to refrigerate this casserole (to let the egg mixture soak into the bread) for at least 2 hours, but I’ve refrigerated it up to 16 hours before and it turned out perfect.
This casserole is baked uncovered, but if it begins to brown too quickly simply cover it with aluminum foil during baking.
I’ve served this casserole on so many occasions (New Years, Christmas, family gatherings) and it has always been a hit. Enjoy!

Do you use Italian or breakfast sausage?
Amy @ The Blond Cook says
Hey Amy, I use hot pork sausage, such as the Jimmy Dean brand. You can use whatever type of sausage you like best in this recipe. Hope you enjoy! 🙂

Amy: Do you think I could make this without the sausage and just increase the amounts of vegetables?

Hey Barb! Yes, I’m pretty sure you can. Hope you enjoy it!
