This char siu chicken is moist and tender, with glossy sticky skin, flavorful meat, and a char siu glaze packed with umami. Learn to use this one secret ingredient to make the best tasting char siu sauce that is naturally red without food coloring. {Gluten-Free Adaptable}
Combine all the sauce ingredients in a large bowl. Stir to mix well.
Transfer the chicken into a large ziplock bag. Reserve 1/4 cup of the mixed sauce for glazing. Pour the rest into the bag. Squeeze out as much air as possible and seal the bag. Massage the bag a few times so the chicken pieces are covered evenly with the sauce. Transfer to the fridge and marinate overnight (highly recommended), or for at least 4 hours.
Roasting
When the chicken is marinated and the glaze is chilled, you’re ready to cook.
Preheat the oven to 375°F (190°C). Line a large baking tray with aluminum foil. Place the chicken onto the tray without overlapping. Bake for 30 minutes.
Turn on the broiler. Baste the top side of the chicken. Broil for 2 to 3 minutes. Baste again. Broil for another 2 to 3 minutes. The chicken should look glossy, lightly charred, and cooked through. You can test the doneness by inserting a thermometer into the thickest part of the chicken. It should read 165°F (74°C).
Once done, cover loosely with aluminum foil. Let rest for 10 minutes before serving. Serve the chicken hot over rice as a main dish.
Notes
Chicken skin is important in this recipe because it holds the glaze better and creates a great texture once baked. I like to use thighs, because they come out juicy and are less likely to dry out. The next best alternative is bone-in chicken on chicken breast. If you prefer using skinless pieces, consider using maltose instead of honey, so the sauce holds onto the meat better. If using skinless pieces, the other option is: Reserve 1/2 cup sauce; gently simmer the sauce (to cook off the raw garlic taste) for 2 to 3 minutes; then serve the chicken with the reserved sauce.
Fermented tofu is the secret ingredient in this recipe, creating a sauce with more umami and giving the char siu a natural red color without food coloring. If you do not have this ingredient, you can use the alternatives instead (soy sauce + salt + red food coloring). That will make a pretty tasty char siu sauce as well.
