01 - Preheat oven to 400°F. Position the rack in the center of the oven.
02 - In a large mixing bowl, whisk together the grated ginger, minced garlic, olive oil, soy sauce, honey, rice vinegar, black pepper, and salt until well combined.
03 - Pat the chicken thighs dry with paper towels. Add them to the marinade and toss thoroughly to coat each piece evenly. Allow to marinate for at least 10 minutes at room temperature, or refrigerate for up to 2 hours for deeper flavor penetration.
04 - Place the marinated chicken thighs in a single layer, skin side up, in a baking dish or on a rimmed sheet pan. Pour any remaining marinade over the top.
05 - Bake for 35 to 40 minutes, until the skin is golden brown and the internal temperature of the thickest part reaches 165°F and juices run clear.
06 - For extra-crispy skin, switch the oven to broil and cook for an additional 2 to 3 minutes, watching carefully to prevent burning.
07 - Remove from the oven and let the chicken rest for 5 minutes. Garnish with sliced green onions and toasted sesame seeds. Serve immediately while hot.
