Chueotang (Loach Soup): A Traditional Summer Stamina Food Guide

What chueotang is

Chueotang is a traditional soup made from ground mudfish (loach), simmered into a thick, hearty broth with perilla seeds, vegetables and often a spicy, doenjang or gochujang-based seasoning. The loach is typically boiled and pureed into the broth itself, so diners generally don't encounter whole fish pieces, and the resulting texture and flavor sits somewhere between a thick stew and a savory porridge.

Why it's considered a summer stamina food

Korea has a long tradition of "boknal" stamina foods -- hearty, protein-rich dishes eaten specifically during the hottest days of summer on the belief that they help the body cope with heat-related fatigue, a tradition samgyetang is best known for internationally. Chueotang holds a similarly respected place in this tradition, particularly in certain regions, valued for its nutrient density and warming, restorative quality despite being eaten in the hottest months.

Chueotang vs samgyetang

• Samgyetang centers on a whole young chicken stuffed with ginseng, rice and jujube, served in a clear, mild broth -- the more internationally familiar stamina dish.
• Chueotang is thicker, spicier and built around ground fish rather than poultry, giving it a heartier, more robust flavor profile.
• Both are traditionally eaten during the hottest stretch of summer, and trying both on the same trip offers a fuller picture of this stamina-food tradition than either alone.

Both chueotang and samgyetang are traditionally eaten during Korea's hottest summer days, following a food-as-medicine philosophy that recommends warming, nutrient-dense meals to counter summer fatigue rather than only cold dishes. Chueotang's blended, thick texture and strong perilla seasoning can be an acquired taste for newcomers, while samgyetang's clearer broth and whole chicken presentation tends to be the more approachable starting point for first-timers. Specialty restaurants for either dish often see their longest lines on the specific traditional dates marking the hottest stretch of summer.
