01 - In a mixing bowl, whisk together the hoisin sauce, soy sauce, honey, oyster sauce, Shaoxing wine, minced garlic, five-spice powder, grated ginger, sesame oil, and red food coloring if using, until smooth and well combined.
02 - Add the chicken thighs to the marinade and coat thoroughly on all sides. Cover the bowl and refrigerate for at least 2 hours, or preferably overnight for the deepest flavor penetration.
03 - Preheat the oven to 400°F (200°C). Line a baking tray with aluminum foil and set a roasting rack on top.
04 - Place the marinated chicken thighs on the roasting rack, allowing excess marinade to drip off. Reserve the leftover marinade in the bowl for basting.
05 - Roast the chicken for 15 minutes. Remove from the oven and brush generously with the reserved marinade using a pastry brush. Return to the oven and continue roasting for another 10 to 15 minutes until the glaze is glossy and deeply caramelized.
06 - For extra color and texture, broil the chicken for 2 to 3 minutes until lightly charred in spots. Remove from the oven and let the chicken rest for a few minutes before slicing.
07 - Slice the chicken and arrange on a serving platter. Scatter with thinly sliced green onions and sesame seeds. Serve alongside steamed rice and stir-fried greens.
