A method of producing retort-sterilized cooked rice including: a heating water-absorption step A for heating uncooked rice having a hardness ratio lower than 1 (one) for causing water to be absorbed therein such that resultant water-absorbed rice grains weigh from 2.0 to 2.6 times as much as the uncooked rice grains； a filling step B for filling the heated, water-absorbed rice grains in a packing container； a sealing step D for sealing the filled packing container； and a retort-sterilization step E for sterilizing the sealed packing container by heating and pressurizing. Also, retort-sterilized container-packed cooked rice comprises rice prepared by retort-sterilizing Indica rice with charging of inert gas in a headspace of the packing container such that the concentration of oxygen gas therein may range 1% or more and less than 2%.
