# Directions:

01 - Preheat oven to 375°F. Line a baking sheet with parchment paper.
02 - Combine ground turkey, breadcrumbs, Parmesan, egg, garlic, parsley, oregano, salt, and pepper in a large bowl. Mix gently until just combined.
03 - Form mixture into 12-16 meatballs, about 1 1/2 inches in diameter. Arrange on prepared baking sheet and bake for 18-20 minutes until cooked through and browned.
04 - Heat olive oil in a large skillet over medium heat. Cook onion until soft, about 3 minutes. Add garlic and red pepper flakes; cook for 30 seconds.
05 - Add marinara sauce and dried basil to the skillet. Simmer for 5 minutes.
06 - Transfer baked meatballs into the sauce. Simmer together for 5-7 minutes, spooning sauce over meatballs to coat thoroughly.
07 - Slice sub rolls without cutting completely through. Place 3-4 meatballs with sauce in each roll.
08 - Top meatballs with shredded mozzarella and sprinkle with Parmesan cheese.
09 - Arrange subs on a baking sheet and broil on high for 2-3 minutes until cheese is melted and bubbly.
10 - Garnish with fresh basil or parsley if desired, and serve warm.

# Expert Suggestions:

01 -
  • The meatballs stay tender because turkey cooks fast and the marinara keeps them from drying out.
  • You can prep the meatballs in advance and freeze them, so dinner comes together in under twenty minutes on a busy night.
  • Broiling the cheese on top gives you that crispy, golden edge that makes every bite feel indulgent without any extra effort.
02 -
  • Do not overmix the meatball mixture or they will turn out dense and dry instead of tender.
  • Simmer the meatballs in the sauce after baking, it keeps them juicy and lets the flavors marry in a way that baking alone cannot achieve.
  • Watch the broiler closely, cheese can go from perfectly melted to burnt in seconds.
03 -
  • Wet your hands before rolling the meatballs so the mixture does not stick and you can shape them quickly and evenly.
  • Let the meatballs rest in the sauce for a few minutes after simmering, they absorb more flavor and the texture improves as everything settles.
