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 the mixture is completely smooth and well combined.
02 - Add the chicken wings to the marinade and toss thoroughly to ensure even coating. Cover the bowl with plastic wrap and refrigerate for a minimum of 30 minutes, though 2 hours will yield a more pronounced flavor.
03 - Preheat the oven to 400°F. Line a baking sheet with parchment paper, or lightly oil a wire rack set over the baking sheet to allow air circulation around the wings.
04 - Remove the wings from the marinade, reserving any excess. Arrange the wings in a single, even layer on the prepared baking sheet or wire rack, ensuring they are not crowded.
05 - Bake the wings for 25 minutes until they begin to develop color. Remove from the oven and brush generously with the reserved marinade, then flip each wing to ensure even caramelization.
06 - Return the wings to the oven and continue baking for an additional 10 minutes, or until the skin is golden brown, caramelized, and the internal temperature reaches 165°F.
07 - For an extra-crispy finish, switch the oven to broil on high for 2 to 3 minutes. Watch carefully during this step to prevent burning, as the miso-honey glaze can char quickly.
08 - Transfer the finished wings to a serving platter. Sprinkle with toasted sesame seeds and thinly sliced green onions. Serve immediately while hot.
