According to the public health network, the time for reheating roast chicken should not be too long, otherwise it will be too dry. If the roast chicken is cold, put it in the microwave oven and heat it for about 10 minutes, which can restore the original taste and color of the roast chicken. If the roast chicken has been cut, the heating time can be shortened to about 5 minutes. When the roast chicken is heated by microwave oven, it is best to wrap it with tin foil to avoid excessive evaporation of water.
