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