  • 1 pound breakfast sausage (we always use Jimmy Dean maple - so good!)
  • 1 loaf Italian bread (use plain white if Italian is unavailable)
  • 1 cup shredded mozzarella cheese
  • 1 cup shredded cheddar cheese
  • 8 eggs
  • 1 cup milk


  1. Brown sausage in skillet.
  2. Slice Italian bread into 1-inch thick slices and cut off crusts.
  3. Grease high-sided 9x13 baking dish and arrange bread so that it completely covers the bottom of the dish (this part is a bit like a jigsaw puzzle).
  4. Drain sausage and spread evenly over bread. Sprinkle cheeses evenly over bread and sausage.
  5. In separate bowl, beat eggs and milk. Pour evenly over all ingredients in pan.
  6. Let set covered in fridge overnight.
  7. When ready to serve, preheat oven to 350 degrees and remove covering.
  8. Bake for about 35 minutes, or until knife poked in center comes out clean. Let stand a few minutes before serving.
