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 to create the marinade.
02 - Add the chicken thighs to the bowl, turning to coat evenly. Cover and marinate in the refrigerator for at least 30 minutes, or up to 4 hours for deeper flavor.
03 - Preheat oven to 400°F. Line a baking tray with parchment paper or foil.
04 - Arrange the marinated chicken thighs skin-side up on the prepared tray. Spoon some extra marinade over the top.
05 - Roast for 35–40 minutes, or until the chicken is cooked through (internal temperature should reach 165°F) and the skin is golden brown. For crispier skin, broil for an additional 2–3 minutes at the end.
06 - Remove from oven and let rest for 5 minutes. Garnish with sliced scallions and toasted sesame seeds, if desired. Serve hot.
