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 a smooth, uniform consistency is achieved.
02 - Add the chicken wings to the marinade and toss thoroughly to ensure even coating. Cover the bowl and refrigerate for a minimum of 30 minutes, or up to 2 hours for more pronounced flavor development.
03 - Preheat the oven to 400°F. Line a baking sheet with parchment paper, or lightly oil a wire rack positioned over the baking sheet to allow airflow beneath the wings.
04 - Place the marinated wings in a single layer on the prepared baking sheet or wire rack. Set aside any remaining marinade for basting during cooking.
05 - Bake the wings for 25 minutes until they begin to develop color and the marinade starts to caramelize.
06 - Remove the baking sheet from the oven. Brush the wings generously with the reserved marinade and flip each piece to ensure even browning on both sides. Return to the oven and continue baking for 10 minutes, or until the wings are golden, deeply caramelized, and cooked through to an internal temperature of 165°F.
07 - For an extra-crispy finish, switch the oven to broil on high for 2 to 3 minutes. Monitor closely to prevent burning, as sugars in the marinade can char quickly.
08 - Transfer the wings to a serving platter and sprinkle generously with toasted sesame seeds and thinly sliced green onions. Serve immediately.
