In a large mixing bowl, combine the ground turkey, panko breadcrumbs, chopped green onions, parsley, minced garlic, beaten egg, soy sauce, grated ginger, and sesame oil. Use your hands or a spatula to mix everything thoroughly until well integrated and cohesive.
Preheat your oven to 400°F (200°C). While the oven is heating, line a baking sheet with parchment paper to prevent sticking and make cleanup easier.
With damp hands (to prevent sticking), scoop out portions of the turkey mixture and roll them into small meatballs, roughly 1 inch in diameter. Arrange the meatballs on the prepared baking sheet, ensuring they are spaced apart to allow even cooking.
Place the baking sheet in the preheated oven and bake the meatballs for 15-20 minutes. They should be golden brown on the outside and have an internal temperature of 165°F (74°C) when fully cooked.
While the meatballs bake, pour the teriyaki sauce into a small saucepan. Heat over low heat, stirring occasionally until warmed through. This helps enhance the flavor of the teriyaki sauce.
Once the meatballs are finished baking, remove them from the oven. You can either drizzle the warmed teriyaki sauce over the meatballs directly on the baking sheet or transfer them to the saucepan and gently toss them to coat evenly in the sauce.
For an appealing presentation, transfer the teriyaki-coated meatballs to a serving platter. Sprinkle with sesame seeds and garnish with additional chopped green onions for a fresh touch.
Notes
Use damp hands to prevent sticking while forming meatballs.
