This homemade char siu delivers tender pork with a glossy, sweet-savory glaze and the signature caramelized edges you expect from classic Chinese BBQ pork. Marinated overnight and roasted until sticky and deeply flavorful, it is perfect for rice, noodles, or bao.
Cut the pork shoulder into long strips or thick slabs about 2 to 3 inches wide. Leave the fat in place so it bastes the meat as it roasts.
In a large bowl, mix the sugar, salt, five-spice powder, white pepper, sesame oil, Shaoxing rice wine, soy sauce, hoisin sauce, molasses, red food coloring if using, and garlic until combined.
Set aside about 2 tablespoons of the marinade for basting later. Rub the remaining marinade all over the pork, cover, and refrigerate for at least 8 hours or overnight. Refrigerate the reserved marinade separately.
When ready to cook, heat the oven to 475 F (246 C) with a rack in the upper third. If your oven runs hot, keep a close eye on the pork and adjust the temperature as needed.
Line a sheet pan with foil and place a wire rack on top. Arrange the pork on the rack with space between each piece, then pour 1 1/2 cups water into the pan underneath to prevent the drippings from burning.
Roast the pork for 10 minutes at 475 F (246 C), then lower the oven temperature to 375 F (190 C). Continue roasting until the first side has cooked for 25 minutes total.
Flip the pork pieces and rotate the pan for even cooking. If the water has evaporated, add about 1 more cup. Roast for 15 minutes more, checking every 10 minutes to make sure the glaze is not scorching.
Meanwhile, stir the reserved marinade with the maltose or honey and 1 tablespoon hot water until smooth. This will be your basting sauce.
After 40 minutes of total roasting time, baste the pork generously, flip, and baste the other side. Roast for 10 minutes more, or until the pork is cooked through and the surface is shiny and caramelized. If needed, broil for 1 to 2 minutes for extra char, watching closely.
Remove the char siu from the oven and brush with any remaining basting sauce. Let rest for 10 minutes before slicing and serving.
Maltose gives the most traditional glossy finish, but honey works well if that is what you have. For best flavor, marinate the pork overnight and do not skip the water in the pan, which helps prevent bitter, burned drippings. Leftover char siu keeps well in the refrigerator for up to 4 days and can be reheated gently or used cold in noodle bowls, fried rice, or buns.
