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 marinade and toss thoroughly to ensure even coating. Cover the bowl and refrigerate for at least 2 hours, or 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 simplify cleanup.
04 - Remove the wings from the marinade and arrange them in a single layer on the prepared baking sheet, spacing them apart for even browning. Set aside any remaining marinade for basting.
05 - Bake for 35 to 40 minutes, turning the wings halfway through and brushing with the reserved marinade. Continue baking until the wings are golden brown and the internal temperature reaches 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.
