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 fully combined.
02 - Add chicken thighs to the bowl, turning to coat evenly. Cover and refrigerate for at least 30 minutes, up to 4 hours for deeper flavor penetration.
03 - Preheat oven to 400°F. Line a baking tray with parchment paper or foil for easy cleanup.
04 - Place marinated chicken thighs skin-side up on prepared tray. Spoon remaining marinade over the top for extra flavor.
05 - Roast for 35–40 minutes until internal temperature reaches 165°F and skin is golden brown. For crispier skin, broil 2–3 minutes at the end.
06 - Remove from oven and let rest 5 minutes to redistribute juices. Garnish with sliced scallions and toasted sesame seeds. Serve immediately.
