BASIC BREAKFAST EGG BAKE
I love a good egg bake. You soak some bread in eggs and milk and throw it in the oven and I’m a happy happy girl. Once you have a basic egg bake recipe you can dress it up a million different ways. To add a Southwestern flair to this recipe here’s what you need:
- Breakfast Sausage: (I used Jennie-O mild breakfast sausage but you could use a spicy ground sausage, turkey sausage or any other kind you like)
- Onions, Garlic and Green Peppers: Finely diced
- Salsa: Any kind will work. I keep it mild for the young people in my house but feel free to go as spicy as you like!
- Mexican cheese blend: You can find some really great pre-shredded options at the grocery store. Colby Jack, Monterrey Jack or Pepper Jack cheeses are all tasty options.
MAKE THIS EGG CASSEROLE THE NIGHT BEFORE
This sausage breakfast casserole is super easy to make the night before.
- Mix in all the ingredients, cover and store in the refrigerator overnight.
- In the morning, let the casserole come to room temperature before popping it into the oven.
- Let it bake for about an hour or until the eggs are set and golden on top.
- Then allow it to sit for about ten minutes before cutting into it.
