Ingredients

Scale
  • 1 lb ground beef (80/20)
  • 1/2 lb ground Italian sausage (optional, or use more beef)
  • 1/2 cup Italian breadcrumbs
  • 1/4 cup grated Parmesan cheese
  • 1 large egg
  • 2 cloves garlic, minced
  • 2 tbsp fresh parsley, chopped (plus more for topping)
  • 1 tsp Italian seasoning
  • 1 tsp kosher salt
  • 1/2 tsp black pepper
  • 2 tbsp milk (or water)
  • 4 hoagie rolls (or sub rolls)
  • 2 cups marinara sauce
  • 1 1/22 cups shredded mozzarella (or provolone)
  • 1 tbsp olive oil (for toasting rolls)
  • Crushed red pepper flakes (optional)

Instructions

  1. Preheat oven to 400°F. Line a baking sheet with parchment paper.
  2. Make the meatball mixture: In a large bowl, combine ground beef, (optional) Italian sausage, breadcrumbs, Parmesan, egg, garlic, parsley, Italian seasoning, salt, pepper, and milk. Mix gently until just combined.
  3. Shape meatballs: Roll into 1 1/2-inch meatballs (about 16–18 meatballs).
  4. Bake meatballs: Place on the baking sheet and bake 16–18 minutes, or until cooked through (160°F internal temp).
  5. Simmer in marinara: Warm marinara in a skillet or saucepan. Add baked meatballs and simmer 5 minutes so they soak up the sauce.
  6. Toast the rolls: Split hoagie rolls and brush lightly with olive oil. Toast in the oven 3–5 minutes.
  7. Assemble: Spoon saucy meatballs into each roll. Top with mozzarella.
  8. Melt the cheese: Broil 1–2 minutes until cheese is bubbly and melted (watch closely).
  9. Finish & serve: Sprinkle with parsley and red pepper flakes (optional). Serve hot!

Notes

  • You can use store-bought marinara sauce for convenience.
  • For extra flavor, add a pinch of red pepper flakes to the meatball mixture.
  • Toast the rolls lightly to prevent them from getting soggy.
