Description

These Mini Meatball Subs are a delicious and comforting handheld meal featuring tender homemade beef meatballs simmered in marinara sauce, nestled inside soft mini sub rolls, and topped with melted mozzarella cheese. Perfect for parties, game days, or a fun weeknight dinner, they combine classic Italian flavors in a convenient slider form.


Ingredients

Meatballs

  • 1 pound ground beef
  • ¼ cup breadcrumbs
  • 1 egg
  • 2 tablespoons grated Parmesan cheese
  • 2 cloves garlic, minced
  • 1 teaspoon Italian seasoning
  • ½ teaspoon salt
  • ¼ teaspoon black pepper

Sauce and Assembly

  • 1½ cups marinara sauce
  • 6 mini sub rolls or slider buns
  • ¾ cup shredded mozzarella cheese
  • 2 tablespoons chopped fresh parsley, for garnish


Instructions

  1. Preheat Oven: Preheat the oven to 375°F (190°C) to prepare for baking the meatballs and final assembly.
  2. Mix Meatball Ingredients: In a large bowl, combine ground beef, breadcrumbs, egg, Parmesan cheese, minced garlic, Italian seasoning, salt, and black pepper. Mix gently until just combined to avoid tough meatballs.
  3. Form Meatballs: Shape the mixture into 18–20 small, evenly sized meatballs to ensure they cook uniformly.
  4. Bake Meatballs: Place the meatballs on a parchment-lined baking sheet and bake in the preheated oven for 15–18 minutes until fully cooked and browned.
  5. Warm Marinara Sauce: While meatballs bake, heat marinara sauce in a saucepan over medium heat to prepare for simmering the meatballs.
  6. Simmer Meatballs in Sauce: Transfer the baked meatballs to the warm marinara sauce and simmer for 5 minutes to allow the meatballs to absorb the rich flavor of the sauce.
  7. Prepare Rolls and Assemble Subs: Slice the mini sub rolls lengthwise. Place 3 meatballs in each roll along with some marinara sauce to keep them juicy.
  8. Add Cheese and Final Bake: Sprinkle shredded mozzarella cheese generously over the filled subs. Place them on a baking sheet and bake for an extra 5–7 minutes until the cheese is melted, bubbly, and slightly golden.
  9. Garnish and Serve: Remove from the oven, garnish with chopped fresh parsley, and serve the mini meatball subs warm for the best taste experience.

Notes

  • You can use store-bought meatballs to save time without compromising flavor.
  • For extra flavor, try toasting the rolls with garlic butter before assembling the subs.
  • These mini subs are perfect for parties, game day snacks, or an easy weeknight dinner option.
