01 - In a large mixing bowl, whisk together soy sauce, oyster sauce, honey, sesame oil, Shaoxing wine, five spice powder, minced garlic, grated ginger, and white pepper until thoroughly combined.
02 - Add chicken thighs to the bowl, turning pieces to ensure even coating. Cover and refrigerate for minimum 30 minutes, up to 4 hours for enhanced 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 on prepared tray skin-side up. Spoon remaining marinade over each piece.
05 - Roast for 35-40 minutes until internal temperature reaches 165°F and skin is golden brown. For extra crispy skin, broil 2-3 minutes at end of cooking time.
06 - Remove from oven and allow chicken to rest for 5 minutes. Garnish with sliced scallions and toasted sesame seeds if desired. Serve immediately.
