01 - In a large mixing bowl, whisk together the white miso paste, honey, soy sauce, rice vinegar, sesame oil, minced garlic, grated ginger, and black pepper until smooth and well combined.
02 - Add the chicken wings to the bowl and toss thoroughly to ensure even coating. Cover tightly and refrigerate for at least 2 hours, preferably overnight for deeper flavor penetration.
03 - Preheat the oven to 400°F. Line a baking sheet with parchment paper or aluminum foil to prevent sticking and ease cleanup.
04 - Arrange the marinated wings in a single layer on the prepared baking sheet, leaving space between each piece for even browning. Reserve any leftover marinade for basting.
05 - Bake for 35 to 40 minutes, turning the wings halfway through and brushing with the reserved marinade to build a caramelized, sticky glaze. The wings are done when deeply golden and cooked through to an internal temperature of 165°F.
06 - Transfer the finished wings to a serving platter and garnish with toasted sesame seeds and thinly sliced green onions. Serve immediately while hot.
