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 fully combined.
02 - Add chicken thighs to the bowl, turning to coat evenly. 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 marinated chicken thighs skin-side up on the prepared baking sheet. Spoon additional 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.
06 - Remove from oven and let chicken rest for 5 minutes to allow juices to redistribute. Garnish with sliced scallions and toasted sesame seeds if desired. Serve hot.
