Preheat oven to 425 F degrees. Line a baking sheet with foil or parchment paper. Set aside.
Whisk together the ingredients for the Soy Ginger sauce. Reserve ¼ cup of sauce in a small bowl for brushing on the chicken while cooking.
Pour the remainder of the sauce over the chicken in a shallow bowl. Turn the chicken to make sure it is fully coated in the sauce, and submerged as much as possible. Marinade chicken for AT LEAST 30 minutes, or over night
When ready to cook, transfer the chicken to a lined baking sheet. Allow extra sauce to drip off and discard the marinade after removing the chicken. Bake at 425 F. for about 10 minutes.
After 10 minutes, remove from oven and brush with the sauce that you had reserved, then return to the oven to cook for 5 more minutes.
After 5 minutes, remove chicken and brush with sauce again. Return to oven for 3-5 more minutes, or until done. Chicken thighs are done when they reach an internal temperature of 165 F - the total cooking time should be 18-25 minutes.
When done, remove from oven and sprinkle with sesame seeds if desired.
Notes
NOTES: Be sure to line your baking sheet with foil or parchment paper - this sauce has sugar in it and it will burn on the baking sheet.Total cooking time for thighs should be 18-25 minutes. I like to brush them with the sauce a few times while cooking to get a nice glaze on them. Brush the sauce on at the 10 minute mark, the 15 minute mark, and the if you want, you can brush them with sauce again at the 20 minute mark and return to the oven for a minute or until they are done.
