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 completely 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 ideally 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 simplify cleanup.
04 - Remove the wings from the marinade and arrange them in a single layer on the prepared baking sheet. Set aside any remaining marinade for basting during cooking.
05 - Bake for 35 to 40 minutes, turning the wings and brushing with reserved marinade halfway through, until the skin is golden brown and the meat is cooked through to an internal temperature of 165°F.
06 - Transfer the finished wings to a serving platter and garnish generously with toasted sesame seeds and thinly sliced green onions. Serve immediately while hot.
