Preheat the Oven: Start by heating the oven to 400°F. This temperature helps the meatballs cook through while staying juicy.
Mix the Meatball Base: In a large bowl add ground chicken, breadcrumbs, egg, soy sauce, garlic powder, onion powder, and chopped green onions. Mix gently with your hands until everything comes together. Avoid pressing too hard so the meatballs stay tender.
Shape the Meatballs: Scoop small portions of the mixture and roll into balls about the size of a golf ball. Place them on a lined baking sheet with a little space between each one.
Bake Until Cooked: Slide the tray into the oven and bake for fifteen to eighteen minutes. The meatballs should look lightly golden and feel firm to the touch.
Warm the Sauce: While the meatballs bake, pour the teriyaki sauce into a small pan. Heat over low until warm and slightly thickened, stirring gently.
Coat the Meatballs: Remove the meatballs from the oven and transfer them into the pan with the sauce. Gently toss until every piece looks shiny and coated.
Finish and Garnish: Sprinkle chopped green onions over the top before serving for fresh flavor and color.
