This honey soy grilled chicken is sweet, savory, glossy, and deeply flavorful after a long marinade. A reserved portion of the marinade becomes a sticky serving sauce, making the chicken perfect with rice, greens, or a simple salad.
Make the marinade by whisking together the soy sauce, honey, cider vinegar, Chinese cooking wine or dry sherry, sesame oil, garlic, and water until the honey is fully dissolved.
Measure out 1/4 cup of the marinade for basting and refrigerate it in a covered container.
Measure out 2/3 cup of the marinade for the serving sauce and refrigerate it separately. Keep these reserved portions away from the raw chicken.
Place the chicken in a shallow dish or zip-top bag. Pour the remaining marinade over the chicken, turn to coat well, cover, and refrigerate for 24 to 48 hours, or at least 3 hours if short on time.
To make the serving sauce, pour the reserved 2/3 cup marinade into a small saucepan. Stir the cornstarch with a little water to make a smooth slurry, then whisk it into the saucepan.
Simmer the sauce over medium heat for about 5 minutes, stirring often, until glossy and lightly thickened. Add a splash of water if it becomes too thick, then keep warm.
Heat a lightly oiled grill, barbecue plate, or large skillet over medium-high heat. Remove the chicken from the marinade and discard the used marinade.
For chicken thighs, cook for about 2 minutes on the first side, flip, and brush with the reserved basting sauce. Continue cooking, flipping and basting every minute, until caramelized and the thickest part reaches 165°F, about 10 minutes total.
For chicken breasts, cook for about 2 minutes on the first side, flip, and baste. Continue cooking, flipping and basting every 45 to 60 seconds, until the thickest part reaches 165°F, about 8 to 10 minutes total depending on thickness.
Transfer the chicken to a plate, loosely cover with foil, and rest for 5 minutes before slicing or serving.
Serve the chicken with the warm honey soy sauce on the side, then garnish with sliced green onion and sesame seeds.
Boneless thighs are more forgiving and stay juicier on the grill, while breasts cook faster and should be watched closely. For best flavor, marinate overnight and always reserve basting and serving sauce before adding any marinade to raw chicken. Leftovers keep well in an airtight container in the refrigerator for up to 3 days.
