I preheat the oven to 400°F (200°C) and line a baking sheet with parchment. In a bowl, I mix 1 lb ground chicken, ½ cup breadcrumbs, ¼ cup Parmesan, 1 egg, 2 cloves minced garlic, 2 tbsp parsley, ½ tsp onion powder, salt, and pepper until just combined. I form 1½-inch meatballs, place them on the sheet, and bake for 15–18 minutes until cooked through. Alternatively, I sear them in 1 tbsp olive oil over medium heat, browning all sides, for this tender chicken meatballs dish.
