Growing up, the rich aroma of my grandmother's kkori gomtang would fill her entire kitchen on cold winter mornings. She'd start the broth before dawn, letting the oxtails simmer for hours until the bones released their deep, nourishing essence. The first spoonful of that milky white Korean oxtail soup was pure comfort - tender meat falling off the bone, surrounded by a broth so rich it felt like a warm embrace. Even now, whenever I make this traditional recipe, I'm transported back to her kitchen table, watching steam rise from my bowl while she'd tell me stories of her childhood in Korea.
Korean oxtail soup represents the pinnacle of Korean comfort food, where time and patience transform humble ingredients into liquid gold. This deeply nourishing kkori gomtang showcases the Korean mastery of extracting maximum flavor and nutrition from bones, creating a milky white broth that's both visually stunning and incredibly satisfying. The long, slow cooking process breaks down collagen into gelatin, resulting in a soup that's not just delicious but also packed with nutrients that Korean families have cherished for generations.
What makes Korean oxtail soup particularly special is its remarkable transformation during the cooking process. The initially clear water slowly turns into an opaque, creamy broth as the oxtail bones release their essence over hours of gentle simmering. Unlike Western oxtail preparations that often rely on heavy seasonings, this traditional Korean approach celebrates the pure, clean flavor of the beef bones themselves, seasoned simply with salt, garlic, and green onions to let the natural richness shine through.
In modern Korean dining culture, kkori gomtang continues to hold its place as the ultimate comfort food, often served at specialized soup restaurants and cherished as a hangover cure or immunity booster. This versatile soup appears on tables during cold winter months, family gatherings, and whenever someone needs deep nourishment. The clean, restorative qualities of the broth make it particularly popular among health-conscious diners who appreciate its natural collagen content and bone-strengthening properties.

Initial blanching: Place oxtail in a large pot, cover with water, and bring to a boil. Boil for 10 minutes, then drain and rinse the oxtail pieces thoroughly under cold water to remove impurities.

Recipe Notes
RECIPE TIPS
- Don't skip the blanching step - it removes impurities for a cleaner broth
- Simmer on the lowest heat possible to prevent the broth from becoming cloudy
- Skim foam regularly during the first two hours of cooking
- The longer you simmer, the richer and whiter the broth becomes
- For extra richness, add a few beef knuckle bones to the pot
- Season gradually - you can always add more salt but can't take it away
SERVING SUGGESTIONS
- Serve with steamed white rice as a complete meal
- Accompany with assorted banchan (Korean side dishes)
- Pair with aged kimchi for traditional flavor balance
- Serve with pickled radish (chicken-mu) for palate cleansing
- Add cooked rice directly to the soup for a hearty one-bowl meal
- Garnish with thinly sliced green onions and fresh garlic
VARIATIONS
- Add sliced rice cakes (tteok) for Korean rice cake soup variation
- Include Korean radish (mu) during the last hour of cooking
- Make it spicy by adding gochugaru (Korean red pepper flakes)
- Add glass noodles (dangmyeon) for extra heartiness
- Include beaten eggs stirred in at the end for egg drop style
- Try with beef short ribs instead of oxtail for galbitang
STORAGE
- Refrigerate leftover soup in airtight containers for up to 4 days
- The broth will gel when cold due to natural collagen - this is normal
- Reheat gently over medium heat, stirring to re-liquify the broth
- Freeze portions for up to 3 months in freezer-safe containers
- Add fresh garnishes when reheating for best flavor
- The soup often tastes even better the next day as flavors meld
