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 and refrigerate for at least 30 minutes, or up to 2 hours for deeper flavor penetration.
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 for even heat circulation.
04 - Remove the wings from the marinade, reserving any excess. Arrange the wings in a single layer on the prepared baking sheet or wire rack, ensuring they are not overcrowded for optimal crisping.
05 - Bake the wings for 25 minutes until the marinade begins to set and the skins start to brown.
06 - Remove the wings from the oven and brush with the reserved marinade. Flip each wing to ensure even caramelization on both sides.
07 - Return the wings to the oven and continue baking for an additional 10 minutes, or until golden, caramelized, and cooked through to an internal temperature of 165°F.
08 - For an extra-crispy finish, switch the oven to broil on high for 2 to 3 minutes, watching carefully to prevent burning.
09 - Transfer the wings to a serving platter and sprinkle generously with toasted sesame seeds and thinly sliced green onions. Serve immediately.
