A heating cooking system comprising:

• a heating cooker that heats a food;
• and
• an external device that is communicably connected to the heating cooker,
• wherein
• the heating cooker includes
• a heating chamber,
• a capturing unit that captures the heating chamber,
• a control unit that controls at least heating of the heated material, and
• a transmitter and receiver that transmits an image captured by the capturing unit to the external device,
• the external device includes
• an appearance characteristic analysis unit that analyzes an appearance characteristic of the heated material based on an image captured by the capturing unit,
• an information reading unit that reads heating control information applied to the heated material from the image captured by the capturing unit,
• an information storage unit in which an acceptable range of the heating control information corresponding to the appearance characteristic is registered,
• an information determination unit that determines whether the heating control information read by the information reading unit is within the acceptable range, and
• a transmitter and receiver that transmits a result of determination by the information determination unit to the heating cooker, and
• when the heating control information read by the information reading unit is within the acceptable range, the control unit executes heating control based on the heating control information read by the information reading unit, and
• when the heating control information read by the information reading unit is not within the acceptable range, the control unit does not execute heating control based on the heating control information read by the information reading unit.
