Preheat oven to 400°F (200°C). Line a large baking sheet with parchment paper or lightly grease with olive oil.

In a small bowl, combine breadcrumbs and milk. Stir until breadcrumbs absorb all liquid and let sit for 5 minutes.

In a large mixing bowl, combine ground turkey, soaked breadcrumbs, beaten egg, minced garlic, parsley, basil, oregano, Parmesan cheese, salt, pepper, and red pepper flakes if using.

Mix ingredients gently but thoroughly until evenly distributed. Avoid overmixing to prevent tough meatballs.

With slightly wet hands, shape mixture into 24 meatballs approximately 1.5 inches in diameter. Place on prepared baking sheet with space between each.

Drizzle olive oil over meatballs or lightly brush each one with oil.

Bake for 20-25 minutes until golden brown and internal temperature reaches 165°F.

While meatballs bake, warm marinara sauce in a large skillet over medium heat.

Transfer cooked meatballs into warm sauce, gently coating each one. Simmer together for 5-10 minutes.

Serve hot, garnished with fresh basil leaves and additional Parmesan cheese if desired.
