An aspect of the present invention provides an induction-heating cooking system comprising an induction-heating cooker and a combined cooker. The combined cooker comprises: an induction-heated part inductively heated with a first electric power by the high-frequency magnetic field generated by the first magnetic field generator; an electric generator electromagnetically induced by the high-frequency magnetic field generated by the second magnetic field generator to generate a second electric power; and a cooking support unit operating by using the second electric power acquired by the electric generator. When the induction-heated part of the combined cooker is placed on the induction heating area and the electric generator of the combined cooker is placed on the cooking device area, the controller controls the first and second inverter circuits independently of each other such that a food cooked by the combined cooker is heated by the induction-heated part while cooking of the food on the induction-heated part is supported by the cooking support unit.
