If it is overnight chicken drumsticks, put the drumsticks directly into a microwave-safe bowl and heat on high for 2 minutes. If you are afraid of drying it out, you can sprinkle some water on the chicken legs. If it is a raw chicken leg, you can marinate the chicken leg first, then put it in the microwave oven and use the "light wave combination" function key or the "BBQ" function key to heat it.
