01 - In a large bowl, whisk together the white miso paste, honey, soy sauce, rice vinegar, sesame oil, minced garlic, grated ginger, chili flakes, and water until completely smooth and well combined.
02 - Add the chicken wings to the marinade and toss thoroughly to ensure even coating. Cover the bowl and refrigerate for at least 30 minutes, or up to 2 hours for deeper flavor penetration.
03 - Preheat oven to 400°F. Line a baking sheet with parchment paper or lightly oil a wire rack set over the baking sheet to allow airflow beneath the wings.
04 - Arrange the marinated wings in a single layer on the prepared baking sheet or wire rack, ensuring they are not overcrowded. Reserve the excess marinade for basting.
05 - Bake the wings for 25 minutes until they begin to develop color and the marinade starts to caramelize.
06 - Remove the wings from the oven and brush generously with the reserved marinade. Flip each wing to ensure even browning on both sides.
07 - Continue baking for an additional 10 minutes until the wings are golden, caramelized, and cooked through to an internal temperature of 165°F.
08 - For a crispier finish, broil on high for 2 to 3 minutes, watching carefully to prevent burning. Transfer to a serving platter and garnish with toasted sesame seeds and sliced green onions.
