PROBLEM TO BE SOLVED: To provide a method for thermally sterilizing food comprising a sterilization process where food is exposed to high temperature for extremely short time to the utmost and also satisfactorily sterilized. SOLUTION: This method for thermally sterilizing food by which semi-cooked food is cooked and sterilized through multistage heat-up comprises the following process in order: a first sterilization process where food sterilization temperature in a sterilization tank is raised up to 120-130°C after cooked; an idling process where temperature in the sterilization tank is lowered to such a level as to be intermediate between the temperature for cooking the food and that for sterilizing the food, and the lowered temperature is maintained for 2-4 min; a second sterilization process where the food sterilization temperature in the sterilization tank is raised up to 120-130°C after idling, and the raised temperature is maintained for 1-5 min; and a cooling process where the food is rapidly cooled.
