Ingredients

Scale
  • 12 frozen or homemade meatballs (about 1½-inch each)
  • 1½ cups marinara sauce
  • 4 sub rolls or hoagie buns
  • 1½ cups shredded mozzarella cheese
  • ½ cup grated Parmesan cheese
  • 2 tablespoons butter, melted
  • 1 teaspoon garlic powder
  • ½ teaspoon Italian seasoning
  • ¼ teaspoon red pepper flakes (optional)
  • 1 tablespoon chopped fresh parsley (for garnish)

Instructions

  1. Preheat Oven: Set your oven to 375°F (190°C).
  2. Prepare Meatballs: If using frozen meatballs, heat them according to the package instructions. If using homemade, cook them in a skillet until browned and cooked through.
  3. Warm the Sauce: In a saucepan, heat the marinara sauce over low heat. Add the cooked meatballs and stir to coat.
  4. Prepare the Rolls: Slice the sub rolls in half, but don’t cut all the way through. Place them in a baking dish.
  5. Fill the Sandwiches: Spoon 3 meatballs into each roll, along with extra sauce. Sprinkle mozzarella and Parmesan cheese evenly over the meatballs.
  6. Make Garlic Butter: Mix melted butter with garlic powder and Italian seasoning. Brush the tops of the rolls with the mixture.
  7. Bake: Cover the dish with foil and bake for 10 minutes. Remove foil and bake for another 5 minutes, or until the cheese is melted and bubbly.
  8. Serve: Sprinkle with parsley and red pepper flakes (if using). Serve warm and enjoy!

Notes

  • Bread Choice: Sub rolls, hoagie rolls, or even ciabatta bread work great.
  • Meatball Options: Use beef, turkey, or plant-based meatballs.
  • Make It Extra Crispy: After baking, broil the sandwiches for 2-3 minutes for a golden, crispy top.
  • Storage: Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in the oven at 350°F for best results.
