Place a roasting rack in a baking dish (to keep your chicken out of the juices). Spray rack with cooking spray.
Pour liquid smoke in the baking dish.
Rinse chicken, pat dry with paper towels. Rub legs with spice mixture. Arrange legs on rack.
Place baking dish in an oven bag and place in SO. Bake until juices run clear, about 45 minutes. If you don’t have an oven bag you can use tin foil and a tea towel.
After 45 minutes, check temperature of the chicken. Make sure it is 165 degrees or more. If needed, cook longer and allow extra time for the Sun Oven to come back up to temp after opening the door for temp check.
