01 - In a mixing bowl, whisk together 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, turning to coat each piece thoroughly. Cover the bowl and refrigerate for at least 2 hours, or preferably overnight for deeper 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 to allow even air circulation around the chicken.
04 - Remove the chicken from the marinade, letting excess drip off back into the bowl. Reserve the leftover marinade for basting. Arrange the chicken thighs on the prepared rack in a single layer.
05 - Roast the chicken for 15 minutes. Remove from the oven and generously brush with the reserved marinade using a pastry brush. Return to the oven and continue roasting for another 10–15 minutes until the glaze is glossy and caramelized.
06 - For extra caramelization, broil the chicken for 2–3 minutes, watching closely to avoid burning. Remove from the oven and let the chicken rest for a few minutes before slicing.
07 - Slice the chicken into pieces and transfer to a serving platter. Scatter sliced green onions and sesame seeds over the top. Serve alongside steamed rice and stir-fried greens.
