Mix the marinade ingredients in a medium bowl. Pour into a large resealable plastic bag and add the chicken thighs. Place on a plate and marinate in the fridge for 1 hour, turning the bag midway.
Preheat your oven to 350 degrees F. Remove the chicken thighs from the bag and arrange them in a baking dish large enough to accommodate them in a single layer. Pour the marinade on top and use your hands to massage it into the chicken thighs.
Bake until well browned and cooked through, about 1 hour, basting the tops with the cooking liquids every 20 minutes. Rinse the basting brush with warm soapy water after each use.
Remove from oven, baste one more time, and serve.
Nutrition info assume about half the marinade is consumed.
