The invention discloses a method for making blood-glucose-decreasing rice by adopting a steam heating cooking utensil. The steam heating cooking utensil comprises a pot and a steam generator. The method for making the blood-glucose-decreasing rice comprises the following steps: (1) a starch release stage, namely, introducing steam into the pot through the steam generator, and heating a rice-watermixture in the pot, so that starch in rice grains separate to water; (2) a water draining stage, namely, carrying out rice-water separation in the pot; and (3) a steaming stage, namely, enabling the steam generator to introduce steam to the pot so that the rice is steamed. According to the method, the high-temperature steam heats the rice-water mixture at the starch release stage, so that the temperature of the rice-water mixture is improved, then starch on the surfaces of and inside the rice grains can rapidly release to water, after the water draining stage, water rich in starch is drained out of the cooking cavity, then the rice is steamed through the high-temperature steam, and therefore, while the mouthfeel of the rice is guaranteed, the content of starch in the rice is greatly reduced.
