A loaded sandwich featuring tender, flavorful meatballs simmered in marinara sauce, topped with melted cheese, and toasted hoagie rolls for a perfect crunchy, cheesy, and comforting meal.

Ingredients

Scale
  • 1 pound ground beef (80/20)
  • ½ cup Italian breadcrumbs (60g)
  • ¼ cup freshly grated Parmesan cheese (25g)
  • 2 cloves garlic, minced (about 1 teaspoon)
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • 1 beaten egg
  • 2 cups marinara sauce (480ml)
  • 4 hoagie rolls (about 6 inches each)
  • 2 cups shredded mozzarella cheese (200g)
  • 2 tablespoons butter (28g)
  • Fresh basil or parsley (optional, for garnish)

Instructions

  1. Mix the ground beef, Italian breadcrumbs, grated Parmesan, minced garlic, salt, black pepper, and beaten egg in a large mixing bowl until just combined.
  2. Shape the mixture into 1½-inch meatballs, about 16 meatballs total.
  3. Heat 1 tablespoon olive oil in a large skillet over medium heat. Brown the meatballs on all sides for 6-8 minutes without cooking through.
  4. Pour marinara sauce over the browned meatballs in the skillet. Reduce heat to low, cover, and simmer gently for 12-15 minutes until meatballs are cooked through and tender.
  5. Slice the hoagie rolls lengthwise, leaving a hinge. Spread butter on the cut sides and toast under the broiler for 2-3 minutes until golden and crisp.
  6. Spoon 4 meatballs and sauce into each toasted roll. Top generously with shredded mozzarella cheese.
  7. Return the assembled subs to the broiler for 1-2 minutes until the cheese melts and bubbles.
  8. Garnish with fresh basil or parsley if desired and serve immediately.

Notes

Do not skip browning the meatballs to lock in flavor and prevent falling apart. Use freshly shredded mozzarella for best melt. Butter the rolls before toasting to get a crispy crust and avoid soggy bread. Simmer meatballs gently to keep them tender. Save extra sauce for dipping. Assemble and serve immediately to prevent soggy bread.
