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 coat evenly. 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. 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, until the skin is deeply golden and the internal temperature reaches 165°F.
06 - Transfer the baked wings to a serving platter and garnish with toasted sesame seeds and thinly sliced green onions. Serve immediately while hot.
