Creamy Meatball Sub Casserole

Ingredients

• 1 pound ground beef
• 1/3 cup chopped green onion
• 1/4 cup seasoned bread crumbs
• 3 tablespoons grated Parmesan cheese
• 1 loaf Italian bread, cut into 1-inch slices
• 1 (8 ounce) package cream cheese, softened
• 1/2 cup mayonnaise
• 1 teaspoon Italian seasoning
• 1/4 teaspoon ground black pepper
• 2 cups shredded mozzarella cheese, divided
• 1 (28 ounce) jar spaghetti sauce
• 1 cup water
• 2 cloves garlic, minced

Directions

Preheat oven to 400 degrees F (200 degrees C).

Mix ground beef, green onion, bread crumbs, and Parmesan cheese together in a bowl; form into 1-inch meatballs. Arrange meatballs in a baking sheet.

Bake in the preheated oven until no longer pink in the center, 15 to 20 minutes. An instant-read thermometer inserted into the center should read at least 160 degrees F (70 degrees C).

Arrange bread slices in a single layer in a 9×13-inch baking dish. Combine cream cheese, mayonnaise, Italian seasoning, and pepper in a bowl; spread over bread slices. Sprinkle 1/2 of the mozzarella cheese over the cream cheese mixture.

Combine spaghetti sauce, water, and garlic in a bowl; add meatballs. Pour spaghetti sauce mixture over bread. Sprinkle remaining mozzarella cheese over casserole.

Bake in the preheated oven until cheese is melted and bubbling, about 30 minutes.
