Make Ahead Breakfast Casserole

Posted on

Christmas morning is just days away and I must admit that I am starting to feel the pressure.

From loads of unwrapped presents to countless cookies that need to be baked, I’m staring at an ever-growing to-do list.

I’m betting you might be feeling the same way, so I decided to take the guesswork out of your Christmas morning meal by sharing this Make Ahead Breakfast Casserole.

This is the first Christmas that we’ll be celebrating in our new home, so we’re having everyone over bright and early to watch Elle open her gifts from Santa.

And since it’s Christmas morning, a family size box of Captain Crunch and a gallon of milk simply isn’t going to cut it for breakfast.

But I’m also not trying to play short order cook all morning, so it’s a make-ahead breakfast for the win!

Make Ahead Breakfast Casserole

Make Ahead Breakfast Casserole is loaded with sausage, cheese and eggs. Assemble it the night before for a simple, delicious breakfast in no time!


  • 1 (16 ounce) package pork sausage
  • 10 eggs, lightly beaten
  • 3 cups milk
  • 1 teaspoon salt
  • 6 cups cubed bread*
  • 2 cups shredded sharp Cheddar cheese
  • 1/2 teaspoon black pepper
  • 1/2 cup diced red pepper, optional
  • sliced green onion, optional


  1. Butter a 9 x 13 x 2 inch casserole dish.
  2. In large skillet, cook sausage over medium-high heat, stirring frequently until thoroughly cooked and no longer pink.
  3. In large bowl, whisk together eggs, milk, and salt until thoroughly combined.
  4. Evenly distribute half the bread into the prepared casserole dish. Sprinkle with half the cheese, half the black pepper, half the red pepper, and half the sausage. Repeat layers.
  5. Pour egg mixture evenly over casserole.
  6. Cover and refrigerate overnight, or bake immediately.
  7. When you’re ready to bake the casserole, preheat oven to 325 F. Bake uncovered for 55-60 minutes, or until eggs are set. If the top begins to brown too quickly, loosely cover the casserole dish with foil.
  8. If desired, sprinkle the casserole with sliced green onions. Serve warm.


  • *I toast my bread before incorporating it into the casserole, but this step is optional.
