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 uniform.
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 your 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 and arrange them in a single layer on the prepared baking sheet or wire rack, ensuring they are not touching. Reserve the excess marinade for basting.
05 - Bake the wings for 25 minutes until the skin begins to firm up and take on light color.
06 - Remove the wings from the oven and brush generously with the reserved marinade. Flip each wing over to ensure even caramelization on both sides.
07 - Continue baking for an additional 10 minutes, or until the wings are golden brown, deeply caramelized, and cooked through to an internal temperature of 165°F.
08 - For an extra crispy exterior, 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 with toasted sesame seeds and thinly sliced green onions. Serve immediately while hot.
