Make the Meatballs Preheat your oven to 425°F. Line a baking sheet with foil and lightly spray it. In a bowl, gently mix the chicken, egg, panko, green onion, soy sauce, miso, ginger, and salt. Don’t overmix — you want the mixture to stay light. Wet your hands and form 15–20 meatballs, depending on your preferred size.
Bake for 20–22 minutes, or until lightly golden and cooked through.
Make the Sauce While the meatballs bake, whisk soy sauce, miso, honey, lemon juice, water, oil, and ginger in a small saucepan. Warm over medium heat until smooth. If you want a thicker, glossy finish, stir in the cornstarch slurry and simmer for 30–45 seconds.
Finish + Serve Pour the warm sauce over the meatballs or toss them directly in the pan for a sticky, glossy coating. Serve with rice, noodles, or roasted veggies.
