Hearty Meatball Sub Casserole

Ingredients 0/12

Step 1

Gently heat your oven to 400°F (200°C). In a bowl, mix together the ground beef, chopped green onion, bread crumbs, and Parmesan cheese until everything is well combined. Roll the mixture into small, 1-inch meatballs and place them on a baking sheet. Pop them in the oven and bake for about 15 to 20 minutes, or until they're cooked through and no longer pink inside—you can check with a meat thermometer to make sure they hit 160°F (70°C).

Step 2

While the meatballs are baking, arrange slices of bread in a single layer in a 9x13-inch baking dish. In a separate bowl, stir together the cream cheese, mayonnaise, Italian seasoning, and a pinch of pepper until smooth. Spread this creamy mixture evenly over the bread slices. Sprinkle half of the mozzarella cheese on top of that.

Step 3

Mix the spaghetti sauce, water, and minced garlic in a bowl. Once the meatballs are done, add them to the sauce and pour everything over the bread in the casserole dish. Finish by sprinkling the rest of the mozzarella cheese on top.

Step 4

Bake the whole thing for about 30 minutes, until the cheese is melted, bubbly, and golden. Let it cool for a few minutes before serving—you’re going to love how comforting and delicious this is!
