Preheat oven to 400°F (200°C) and line a baking sheet with parchment paper.
Mix ingredients: In a large bowl, combine ground turkey, breadcrumbs, egg, Parmesan, garlic, oregano, basil, salt, pepper, and parsley. Mix gently.
Form meatballs: Use your hands or a tablespoon to shape the mixture into balls. Optional: place mozzarella inside for a cheesy center.
Bake: Arrange meatballs on the prepared baking sheet and bake 18–20 minutes, until lightly browned and cooked through.
Serve: Enjoy on their own, with marinara sauce, pasta, or roasted veggies.
