Abstract: A steam cooker includes a steam supply device for generating and supplying steam, and a cooking container for receiving steam from the steam supply device and cooking food contained therein, wherein the cooking container includes a first containing unit for containing food therein, a second containing unit formed to communicate with the lower portion of the first containing unit and receives steam from the steam supply device, and a cap provided on the upper portion of the first containing unit and receives steam from the steam supply device. With the steam cooker, food is supplied with steam both from above and from below, thereby evenly cooking the entire food, and condensed water, which is generated when moisture contained inside the steam is condensed, is easily discharged to the outside, thereby preventing degradation of taste of the food resulting from contact between the food and the condensed water.
