Ingredients:

  • 2 lbs frozen Italian-style meatballs
  • 24 oz marinara sauce
  • 1 tsp dried oregano
  • 1/2 tsp crushed red pepper flakes
  • 2 cloves minced garlic
  • 6 hoagie rolls
  • 8 oz shredded mozzarella cheese
  • 4 tbsp unsalted butter, softened
  • 1/4 cup grated Parmesan cheese
  • Fresh parsley, chopped

Instructions:

  1. Place the frozen or homemade meatballs in the bottom of the slow cooker.
  2. Pour the marinara sauce over the meatballs and stir in the minced garlic, oregano, and red pepper flakes, ensuring meatballs are fully submerged.
  3. Set the slow cooker to HIGH for 3-4 hours, stirring once halfway through the cooking process, until the sauce is thick and meatballs are tender.
  4. Preheat the broiler. Split the rolls and spread a thin layer of softened butter on the cut sides.
  5. Place the buttered rolls on a baking sheet and broil for 1-2 minutes until the edges are golden brown.
  6. Nestle 3-4 meatballs into each roll and spoon extra sauce over the top.
  7. Top each sub with mozzarella and Parmesan cheese.
  8. Return the subs to the broiler for 1-3 minutes until the cheese is bubbling and charred.
  9. Garnish with freshly chopped parsley before serving.
