Overnight Sausage Breakfast Casserole with sausage, peppers, cheese and Italian seasoning is one my favorite make ahead breakfasts!


  • 14 slices bread crust removed, cubed and dried (see note)
  • 1 package Johnsonville Naturals Italian Sausage
  • 3 green onions sliced
  • ½ red bell pepper finely diced
  • ½ green bell pepper finely diced
  • 2 cups shredded Italian blend cheese
  • 2 cups mozzarella cheese
  • 6 eggs
  • 3 cups milk
  • 1 teaspoon Italian seasoning
  • pepper to taste


  • Remove casing from sausage and cook over medium high heat until no pink remains. Drain any fat.
  • Layer ½ of the cubes in a greased 9×13 pan. Top with ½ of each the sausage, green onions, peppers, and cheese. Repeat layers ending with cheese.
  • Combine eggs, milk, & seasonings Pour egg mixture over bread ensuring all of the bread has been covered. Refrigerate overnight (or at least 3 hours).
  • Remove from fridge and place in the oven while preheating the oven to 350 degrees. Bake covered with foil 65-75 minutes or until a knife inserted in the center comes out clean. (If you are baking 2 pans increase cooking time will need to increase).

Recipe Notes

Allow bread to dry overnight or dry slightly in the oven oven at 300 degrees for about 10 minutes to dry slightly. (Do not brown or toast it).
