In a large mixing bowl, combine the ground turkey, breadcrumbs, grated Parmesan cheese, minced garlic, chopped parsley, dried basil, dried oregano, salt, black pepper, and beaten egg. Mix well until all ingredients are thoroughly combined.
Preheat a large skillet over medium heat and add olive oil.
With wet hands, form the turkey mixture into meatballs, about 1 to 1.5 inches in diameter, and place them on a plate.
Once the skillet is hot, add the meatballs in batches (do not overcrowd the pan) and cook for about 6-7 minutes, turning occasionally, until they are golden brown on all sides and cooked through.
While the meatballs are cooking, heat the marinara sauce in a separate saucepan over low heat until warmed through.
Once the meatballs are done, serve them hot over the marinara sauce, garnished with additional parsley if desired.
Notes
Serve with additional parsley for garnish if desired.
