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