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 the mixture is completely smooth and well combined.
02 - Add the chicken wings to the bowl 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 ease cleanup.
04 - Remove the wings from the marinade and arrange them in a single layer on the prepared baking sheet. Set aside any leftover marinade for basting during cooking.
05 - Bake the wings for 35 to 40 minutes, turning them halfway through and brushing with the reserved marinade. Continue baking until the wings are golden brown and fully cooked through.
06 - Transfer the finished wings to a serving platter and garnish with toasted sesame seeds and thinly sliced green onions. Serve immediately while hot.
