Ingredients:
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
Directions:
Step 1: Preheat oven to 425 degrees F (220 degrees C).
Step 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.
Step 3: Reduce oven temperature to 350 degrees F (175 degrees C).
Step 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.
Step 5: Tear garlic bread into bite-size pieces and spread into bottom of a 9×13-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.
Step 6: Bake casserole until cheese has melted, 20 to 25 minutes.
