Combine ground turkey, breadcrumbs, chopped parsley, beaten egg, minced garlic, salt, and pepper in a large mixing bowl. Mix thoroughly until all ingredients are evenly incorporated, creating a uniform mixture that holds together when formed into balls.
Use your hands or a cookie scoop to portion about one to two tablespoon-sized amounts of the mixture and roll into smooth, round meatballs. Place them evenly spaced on a prepared baking sheet or tray.
Bake in a preheated oven at 375°F (190°C) for approximately 15-20 minutes, or until the meatballs are golden brown and cooked through. Alternatively, heat oil in a skillet over medium heat and cook the meatballs in batches, turning occasionally, until evenly browned and cooked through.
Remove the cooked meatballs from the oven or skillet and transfer to a plate lined with paper towels or a wire rack to drain excess fat. Observe the exterior for a uniform golden hue and ensure no pink remains inside.
Arrange the meatballs on a serving platter, optionally garnished with additional chopped herbs. Serve hot with your favorite dipping sauce or in pasta dishes, presenting a moist interior framed by a crispy exterior.
