These char siu chicken thighs bring the sweet-savory flavor of Chinese barbecue to an easy oven-roasted dinner. The marinade caramelizes into a glossy glaze, giving the chicken deep color, juicy meat, and lightly charred edges.
Trim away any large pieces of excess fat from the chicken thighs. In a large bowl, mix the brown sugar, salt, five-spice powder, white pepper, hoisin sauce, Shaoxing wine, soy sauce, sesame oil, garlic, and red food coloring if using.
Add the chicken to the bowl and turn to coat every piece well in the marinade. Cover and refrigerate for at least 8 hours or overnight for the best flavor.
When ready to cook, heat the oven to 375°F (190°C) with a rack in the center. Line a sheet pan with foil and top with parchment paper or nonstick foil. Arrange the chicken thighs in a single layer, leaving space between them. Reserve the leftover marinade.
Roast the chicken for 30 minutes. Check it halfway through; if the surface is browning too quickly, loosely cover it with foil.
Meanwhile, pour the reserved marinade into a small saucepan with the water. Bring it to a gentle simmer and cook for 2 to 3 minutes. Add the maltose and stir until fully melted and smooth, then remove from the heat.
Brush the chicken generously with the cooked basting sauce and return it to the oven for 5 to 10 minutes more, or until the thickest part reaches 165°F (74°C). For extra caramelization, baste once more and roast for 1 additional minute before serving.
If you cannot find maltose, use honey for a similar sticky glaze. Dry sherry is a good substitute for Shaoxing wine. Do not baste with raw marinade unless it has been fully simmered first. Leftovers keep well in the refrigerator for up to 3 days and reheat best in the oven or air fryer.
