Instructions

  • Lightly spray a 9x13" casserole dish with non stick cooking spray. Arrange the bread slices evenly out in the baking dish, breaking up extra pieces to fill in any gaps.
    1 loaf Italian bread
  • In a small mixing bowl, add the cream cheese, mayo, and Italian seasoning. Stir the mixture together until evenly incorporated.
    4 oz cream cheese, 1/4 cup mayonnaise, 1 tsp Italian seasoning
  • Spoon the cheese mixture over the bread in dollops until it's all used. Use a spatula, or the back of a spoon, to spread the cheese mixture evenly out over the bread. Sprinkle the 1/2 cup of Parmesan evenly out over the top.
    1/2 cup Parmesan cheese
  • In a separate mixing bowl, toss together the meatballs and the sauce until well coated.
    1 26-32 oz bag large frozen meatballs, 1 28 oz jar pasta sauce
  • Spoon the the meatball mixture evenly out over the casserole, including all sauce. Sprinkle the remaining cheese evenly out over the top.
    1 1/2 cups mozzarella cheese
  • Bake the casserole at 350 degrees for 30-35 degrees, or until golden brown & bubbly.

Notes

  • You can use any kind of meatballs you'd like. Chicken, beef, turkey, etc. are all ok.
  • If you want the casserole to stay together more when you serve it, let it rest for 5 minutes or so after you take it out of the oven before cutting it.
  • Don't forget to spray the casserole dish with cooking spray so it doesn't stick!
