Ingredients:
- 1/3 cup chopped green onion
- 1/4 cup seasoned bread crumbs
- 3 tablespoons grated Parmesan cheese
- 1 pound ground beef
- 1 loaf Italian bread, cut into 1-inch slices
- 8 ounces cream cheese, softened
- 1/2 cup mayonnaise
- 1 teaspoon Italian seasoning
- 1/4 teaspoon pepper
- 2 cups shredded mozzarella cheese, divided
- 1 (28-ounce) jar of your favorite spaghetti sauce
- 1 cup water
- 2 garlic cloves, minced
Instructions:
- Prepare the Meatballs: Preheat your oven to 400 degrees Fahrenheit. In a bowl, mix together chopped green onions, seasoned bread crumbs, and grated Parmesan cheese. Add ground beef and thoroughly combine. Shape the mixture into 1-inch balls and place them on a baking sheet. Bake for 15-20 minutes until the meatballs are no longer pink. Alternatively, you can fry them in a skillet on medium heat.
- Prepare the Bread Base: Reduce the oven temperature to 350 degrees Fahrenheit. Arrange slices of Italian bread in a single layer in an ungreased 13×9 baking dish. You might not use all of the bread.
- Prepare the Cheese Mixture: In another bowl, combine softened cream cheese, mayonnaise, Italian seasoning, and pepper. Spread this mixture over the bread slices. Sprinkle with 1/2 cup of shredded mozzarella cheese.
- Combine Sauce and Meatballs: In a saucepan, combine your favorite spaghetti sauce with water and minced garlic. Add the baked meatballs to the sauce mixture.
- Assemble the Casserole: Pour the sauce and meatball mixture over the cheese-covered bread in the baking dish. Sprinkle the remaining shredded mozzarella cheese on top.
- Bake: Bake the casserole, uncovered, at 350 degrees Fahrenheit for 30 minutes or until the cheese is melted and bubbly.
- Serve and Enjoy: Once the casserole is done baking, remove it from the oven and let it cool slightly before serving. Slice into squares and enjoy the delicious flavors of this meatball sub casserole!
