Meatball Sub Casserole


My boys LOVE this! It is quick and simple! I am always asked to bring this to Super Bowl® parties and family events!

8 servings


  • 1 (16 ounce) package frozen garlic bread

  • 2 (24 ounce) jars spaghetti sauce

  • 40 Italian-style frozen meatballs

  • 2 cups shredded mozzarella cheese

  • ¼ cup grated Parmesan cheese


  1. Preheat oven to 425 degrees F (220 degrees C).

  2. Heat garlic bread with spread side up on a baking sheet in the preheated oven until warm and golden brown, 10 to 12 minutes. Set aside to cool.

  3. Reduce oven temperature to 350 degrees F (175 degrees C).

  4. Bring spaghetti sauce to a boil in a large pot. Place frozen meatballs into sauce. Reduce heat to low and simmer until meatballs are heated through, about 20 minutes.

  5. Tear garlic bread into bite-size pieces and spread into bottom of a 9x13-inch baking dish. Pour spaghetti sauce and meatballs over garlic bread, coating bread with sauce and distributing meatballs evenly. Spread mozzarella cheese over top in a layer, followed by a layer of Parmesan cheese.

  6. Bake casserole until cheese has melted, 20 to 25 minutes.

Cook's Note:

If you are using the frozen garlic toast that is already sliced packaged in boxes, I usually need 2 boxes. I have even used the frozen garlic bread with cheese, and it is great too!
