Toranguk is the Korean taro soup traditionally associated with Chuseok.
The soup uses taro, a starchy underground plant, in a savory broth. Taro is harvested in autumn and became part of the seasonal foods served during Korea’s harvest festival. Chuseok meals vary by household and region, but toranguk is frequently listed among the holiday’s traditional dishes.
The name can also appear in romanization as toran-guk or toranguk. “Guk” means soup in Korean culinary terminology, while toran refers to taro. The dish should not be confused with tteokguk, the rice-cake soup traditionally linked with Lunar New Year.
Chuseok food traditions also include songpyeon, jeon, fruit, and newly harvested grains. Toranguk is especially notable because it connects the festival’s menu directly with an autumn crop.
