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 with the marinade. Cover and refrigerate for at least 30 minutes, up to 4 hours for enhanced flavor penetration.
03 - Set oven to 400°F. Line a baking tray with parchment paper or aluminum foil for easy cleanup.
04 - Place marinated chicken thighs on the prepared baking sheet, positioning them skin-side up. Spoon remaining marinade over the top of each piece.
05 - Roast for 35-40 minutes until the internal temperature reaches 165°F and the skin turns golden brown. For extra crispy skin, broil for an additional 2-3 minutes at the end of cooking time.
06 - Remove chicken from the oven and let rest for 5 minutes to allow juices to redistribute. Garnish with sliced scallions and toasted sesame seeds before serving.
