How to Make Overnight Breakfast Casserole

  1. Grease a 7x12 inch baking dish.

  3. Cook 1 pound of sausage (your choice!) until browned; crumble and sprinkle evenly over the bread cubes.
  4. Sprinkle 2 cups of shredded cheddar cheese (or your favorite cheese) over the sausage.
  5. In a large bowl, whisk together 6 large eggs, 1 ½ cups of milk, 1 teaspoon dry mustard, 1 teaspoon salt, and ½ teaspoon black pepper.
  6. Pour the egg mixture evenly over the bread, sausage, and cheese layers.
  7. Cover the baking dish with plastic wrap and refrigerate overnight (or for at least 4 hours).
