Preheat the oven to 200C/400F. Line a large baking tray with parchment paper and set aside.
In a mixing bowl, combine ground chicken, egg, milk, garlic, Italian seasoning, garlic powder, salt, and pepper. Mix everything until just combined.
Using lightly wet hands, roll out 20 meatballs. Place them a wire rimmed baking sheet or baking tray lined with aluminum foil.
Bake the meatballs for 15-17 minutes, or until fully cooked. Use a meat thermometer to check that they have reached an internal temperature of 165F.
