How To Make Mini Meatball Subs on Slider Buns


  1. Prepare the Meatballs:
  • In a large mixing bowl, combine ground beef, breadcrumbs, grated Parmesan cheese, milk, egg, minced garlic, chopped parsley, dried oregano, dried basil, onion powder, salt, and black pepper.
  • Gently mix all the ingredients together until well combined. Be careful not to overwork the meat mixture to keep the meatballs tender.
  • Shape the mixture into mini meatballs, about 1 inch in diameter, and place them on a baking sheet lined with parchment paper.
  1. Bake the Meatballs:
  • Preheat your oven to 375°F (190°C).
  • Bake the mini meatballs in the preheated oven for about 15-20 minutes or until they are cooked through and slightly browned on the outside.
  1. Prepare the Marinara Sauce:
  • In a medium saucepan, heat the olive oil over medium heat.
  • Add the minced garlic and sauté for a minute until fragrant.
  • Pour in the crushed tomatoes, dried basil, dried oregano, salt, and black pepper. Stir to combine.
  • Bring the sauce to a simmer and let it cook for about 10 minutes, stirring occasionally. Adjust the seasoning to taste.
  1. Assemble the Mini Meatball Subs:
  • Preheat your oven's broiler.
  • Take a large chef’s knife and slice the mini sub rolls or slider buns in half lengthwise.
  • Place a few mini meatballs on one half of each roll.
  • Spoon some marinara sauce over the meatballs and place a slice of provolone or mozzarella cheese on top.
  • Arrange the prepared subs on a baking sheet.
  1. Broil the Subs:
  • Place the baking sheet with the subs under the broiler until the cheese melts and becomes bubbly and slightly browned. This should take just a few minutes, so keep a close eye on them to prevent burning.
  1. Garnish and Serve:
  • Remove the mini meatball subs from the oven and garnish with fresh basil leaves, if desired.
  • Serve the hot and gooey mini meatball subs immediately, either as a main course or as a fun appetizer for your guests to enjoy.
