Provided is a bidirectional heating cooker that supplements and improves a function of a conventional infrared radiation cooker, in which the bidirectional heating cooker further includes a lower heating unit that is placed at the lower end of a cooking pan that is heated by radiant heat irradiated by an infrared lamp and that directly heats the cooking pan, to thereby heat the cooking pan quickly by the lower heating unit to thus make the upper and lower portions of food such as meat put on the cooking pan more quickly roasted than the conventional infrared radiation cooker and reduce a burden of electric charges based on a shortened heating time of the cooking pan, and to thereby make it possible to cook food rapidly by an upper heating unit with the infrared lamp and the lower heating unit that is placed on the cooking pan.
