01 - Whisk together soy sauce, oyster sauce, honey, sesame oil, Shaoxing wine, five spice powder, minced garlic, grated ginger, and white pepper in a large bowl until well combined.
02 - Add chicken thighs to the bowl, turning to coat evenly with marinade. Cover and refrigerate for at least 30 minutes, or up to 4 hours for deeper flavor development.
03 - Preheat oven to 400°F. Line a baking tray with parchment paper or foil for easy cleanup.
04 - Place marinated chicken thighs on prepared tray skin-side up. Spoon excess marinade over the top of each piece.
05 - Roast for 35–40 minutes until chicken reaches internal temperature of 165°F and skin is golden brown. For extra crispy skin, broil for 2–3 minutes at the end of cooking time.
06 - Remove from oven and let chicken rest for 5 minutes. Garnish with sliced scallions and toasted sesame seeds if desired. Serve hot with steamed rice.
