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, or preferably overnight for maximum 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 - Remove the wings from the marinade and arrange them in a single layer on the prepared baking sheet, leaving space between each piece for even cooking. Set aside any remaining marinade for basting.
05 - Bake the wings for 35 to 40 minutes, turning them and brushing with the reserved marinade halfway through, until the skin is golden and caramelized and the internal temperature reaches 165°F.
06 - Transfer the wings to a serving platter and garnish with toasted sesame seeds and thinly sliced green onions. Serve immediately while hot.
