Step-by-Step Instructions
  1. Grease the slow cooker and place the frozen meatballs in an even layer. Pour the marinara sauce over the meatballs and mix gently. Set to low for 6-7 hours or high for 3-4 hours.
  2. Preheat the oven to 350°F (175°C) about 30 minutes before the cooking time is complete.
  3. Slice the hoagie buns in half lengthwise. Arrange bottom halves on a baking sheet, layer with cheese and pepperoni if desired.
  4. Spoon 6 meatballs onto each hoagie bun, drizzle with marinara sauce, and sprinkle with shredded mozzarella and Parmesan.
  5. Bake the subs in the preheated oven for 5-6 minutes until the cheese is melted and bubbly, and buns are golden brown.
  6. Remove from the oven, let cool for a minute, and serve warm.

To avoid soggy buns, layer cheese and toppings before adding meatballs. For a casual setting, skip the baking step and serve meatballs directly from the slow cooker.
