Rinse and pat dry chicken thighs.
In a large bowl, combine the remaining ingredients and stir until smooth. Add thighs and make sure they are coated. Cover with plastic wrap and refrigerate at least 2 to 3 hours, preferably overnight.
Set up grill for indirect cooking over medium-high heat. Oil grate when ready to start cooking. Remove chicken from refrigerator and let sit at room temperature for 30 minutes.
Cook 40 to 45 minutes or until internal temperature reaches 180 degrees F. Check for doneness by cutting into thigh to make sure there is no redness near bone.
NOTE INDOOR GRILLING: Prepare chicken as directed. Preheat oven to 425 degrees F. Roast in preheated oven on foil lined baking sheet for 30 minutes or until internal temperature reaches 180 degrees F.
