Meatball Sub Casserole is a baked twist on the classic meatball sub sandwich, layering crusty bread, savory meatballs, rich marinara sauce, and melty cheese in one comforting dish. Perfect for family dinners, potlucks, or easy weeknight meals.

Ingredients

  • 16–20 frozen or homemade meatballs (thawed if frozen)
  • 3 cups marinara sauce
  • 1 loaf sub rolls, French bread, or Italian bread, cut into thick slices
  • 8 oz cream cheese, softened
  • 1/4 cup mayonnaise or sour cream
  • 1 tsp Italian seasoning
  • 1/2 tsp garlic powder
  • 2 cups shredded mozzarella cheese
  • 1/4 cup grated Parmesan cheese
  • Fresh parsley or basil, chopped (optional, for garnish)

Instructions

  1. Preheat oven to 375°F (190°C).
  2. In a bowl, mix softened cream cheese, mayonnaise or sour cream, Italian seasoning, and garlic powder until smooth.
  3. Grease a 9×13-inch baking dish and arrange bread slices in a single layer.
  4. Spread the cream cheese mixture evenly over the bread.
  5. Top with cooked or thawed meatballs.
  6. Pour marinara sauce evenly over the meatballs.
  7. Sprinkle mozzarella and Parmesan cheese over the top.
  8. Cover with foil and bake for 25–30 minutes.
  9. Remove foil and bake for another 10–15 minutes, until cheese is melted and golden.
  10. Garnish with chopped parsley or basil, let rest for 5 minutes, and serve hot.

Notes

  • Use garlic butter on the bread for a garlic bread base.
  • Add sautéed veggies like bell peppers or onions for extra flavor.
  • Use provolone or ricotta cheese for a cheesier variation.
  • Great for meal prep—assemble ahead and bake when ready.
  • Make a half batch in an 8×8-inch dish for smaller households.
