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 well combined.
02 - Add the 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 foil for easy cleanup.
04 - Place the marinated chicken thighs skin-side up on the prepared baking sheet. Spoon any remaining marinade over the top of each piece.
05 - Roast for 35–40 minutes until the chicken is cooked through (internal temperature reaches 165°F) and the skin is golden brown and crispy. For extra crispiness, broil for an additional 2–3 minutes at the end.
06 - Remove from the oven and let the chicken rest for 5 minutes to allow juices to redistribute. Garnish with sliced scallions and toasted sesame seeds before serving.
