01 - Whisk together hoisin sauce, honey, soy sauce, oyster sauce, Shaoxing wine, brown sugar, sesame oil, five-spice powder, ginger, garlic, and food coloring in a large bowl until smooth.
02 - Add chicken thighs to the bowl, toss to coat thoroughly. Cover and refrigerate for at least 2 hours, preferably overnight for maximum flavor penetration.
03 - Set oven to 425°F. Line a baking sheet with aluminum foil and place a wire rack on top.
04 - Remove chicken from marinade, reserving the liquid. Place thighs on the wire rack with space between pieces for even cooking.
05 - Roast for 20 minutes. Remove from oven, baste generously with reserved marinade, flip pieces, and baste again.
06 - Return to oven and roast 10-15 minutes longer, basting once more, until edges are caramelized and internal temperature reaches 165°F.
07 - Let chicken rest 5 minutes before slicing. Garnish with spring onions and sesame seeds. Serve hot with steamed rice, noodles, or in bao buns.
