What to Eat in Seoul: Jongno’s Seolleongtang (설렁탕), Korea’s Ox-Bone Soup

In the historic heart of Seoul lies Jongno (종로) — the old downtown where visitors wander the art alleys of Insadong, bow before centuries-old palaces, and graze the food stalls of Gwangjang Market. And tucked into these same streets is the oldest restaurant in the entire country, still doing the one thing it has done since 1904: ladling out seolleongtang (설렁탕).

There’s a particular kind of cold Seoul morning when the only warm thing on the block is a little shop with its windows fogged white — and inside, almost everyone is bent over the same milky bowl of soup. That soup is seolleongtang, and I’ve ordered it more mornings than I can count.

First — what exactly is seolleongtang?

Seolleongtang is one of the most popular and traditional dishes we have in Korea — and I mean everywhere. Wander almost any Korean neighborhood and you’ll pass a seolleongtang shop every few blocks, steam curling out the door. It isn’t special-occasion food. It’s the soup people eat on an ordinary Tuesday.

Why the broth is milky white

The first thing you’ll notice is the color — a cloudy, milky white, almost as if someone stirred milk into it.

They didn’t. That color comes purely from ox bones simmered for a very long time, often twelve hours or more, until the broth turns rich and opaque all on its own. The way I see it, that’s the whole magic: no shortcuts, just bone and patience. It’s also why a bowl feels so quietly restorative when you’re tired or cold.

How to eat it like a local

Here’s the part that surprises a lot of first-timers: it arrives looking almost pale and simple. When the bowl first lands, before you add anything, it can taste a little plain — even mild. But add a small pinch of salt, give it a stir, and a deep, savory richness suddenly blooms out of the broth. That’s by design. The seasoning is your job.

Koreans reach for the salt and chopped scallions on the table, and quite a few of us also splash in a bit of kimchi brine for a tangy kick. Personally? I like mine with just salt and scallions, and I eat the kimchi on the side rather than pouring it in. There’s no wrong answer — half the fun is building the bowl to your own taste.

Two more things I wish someone had told me early on.

Don’t grab the bowl

Seolleongtang is served in a ttukbaegi, a heavy earthenware pot, and it comes out genuinely scorching — hot enough to burn your fingers if you grip the rim. Give it a moment, and use your spoon.

Noodles first, rice last

There are usually thin somyeon noodles hiding in the broth, and they turn soft and mushy if they sit too long. So I go for the noodles early. Then, near the end — the classic move — I tip in the rice and eat it soaked up in the last of the broth. Noodles first, rice last. That little sequence is how most Koreans actually work through the bowl.

The royal secret behind the soup

So here’s what genuinely floored me when I started digging. This humble, everyman’s soup? It may have started at a royal altar. I’d always known seolleongtang as pure working-class comfort food, so the idea that it could be tangled up with kings never once crossed my mind. I was as surprised as you probably are right now.

It begins at an altar called Seonnongdan

The trail leads to a small stone altar in eastern Seoul, in what’s now the Jegi-dong neighborhood, called Seonnongdan (선농단).

For centuries, the kings of the Joseon dynasty came here to bow to the gods of agriculture — the mythical fathers of farming — and pray for a good harvest. This wasn’t a minor errand. A bad harvest meant a hungry kingdom, so the ritual carried the weight of the whole nation’s survival on it.

And the king didn’t simply pray from the sidelines. As part of the rite, he gripped an actual plow and turned the soil with his own hands — a ceremony called chingyeong. Picture it for a second: the most powerful man in the country, out in a field, hands on a plow, publicly bowing to something even he couldn’t command. The rice.

A king, an ox, and a soup for everybody

Here’s where the soup finally enters the story. As the tradition goes, once the ceremony was finished, a whole ox was slaughtered and boiled down in enormous cauldrons — so the king could sit and share a meal with the ordinary farmers who worked the land. One giant pot. Everyone fed. Nothing wasted.

Think about how radical that image is: a king and a farmer, eating the same soup from the same cauldron, on the same day. That communal broth, the story says, was named seonnongtang after the altar itself.

And then time did what time does to words. Over centuries of people saying it fast in everyday speech, seonnongtang slowly wore down — seonnong, seolleong — into the word we use today: seolleongtang. A royal ritual dish, softened by generations of ordinary mouths into a soup for everyone. I find that genuinely beautiful.

But historians don’t all agree

Now, the historical picture here is genuinely divided, and it’s only fair to tell you so.

The Seonnongdan version is the most beloved explanation, but it isn’t the only one scholars put forward. Some trace the name to the Mongolian word sülen, an old term for a meat broth — a linguistic fingerprint left over from the Goryeo era, when Korea had deep Mongol ties. Others say it comes from seolnong (雪濃), meaning “snow-thick,” a nod to that cloudy white color.

So which is true? Honestly, nobody can say for certain, and that’s part of the charm. But notice what every version has in common: a warm, humble bowl meant to be shared as widely as possible. Whichever theory you land on, that spirit is pure Seonnongdan.

Where to eat it in old-town Seoul

One a living piece of history right in Jongno, the other a short walk away in the old downtown:

Imun Seolnongtang (이문설농탕) — Korea’s oldest restaurant, in Jongno

Opened in 1904 and widely recognized as the oldest continuously running restaurant in the country, Imun holds Seoul restaurant license No. 1 and carries a Michelin Bib Gourmand. The broth is clean and gently nutty, four generations deep — and it’s right in Jongno, a few minutes’ walk from Insadong and Jogyesa Temple.

Jaembaeok (잼배옥) — a downtown classic since 1933

A short walk toward City Hall, in old downtown Seoul, Jaembaeok has been ladling seolleongtang since 1933 — the unpretentious, decades-deep kind of place where nearby office workers file in daily. Handy if you’re already around Deoksugung Palace or Jeong-dong.

• 📍 Address: 68-9 Sejong-daero 9-gil, Jung-gu, Seoul (서울 중구 세종대로9길 68-9)

One honest caveat: prices and hours are accurate as of July 2026, but small restaurants change both more often than you’d expect. A quick check before you go never hurts.

A few quick questions

Is seolleongtang spicy?
Not at all — it arrives plain and mild, and you steer the flavor yourself with salt, scallions, and kimchi. It’s one of the friendliest Korean dishes for a first-timer.

Is it the same as gomtang?
They’re cousins. Both are boiled beef soups, but seolleongtang leans on bones (hence the milky white), while gomtang uses more meat and comes out clearer.

Can I really eat it for breakfast?
Absolutely. Many of the oldest shops open at dawn precisely because a hot, cheap, filling bowl is a perfect way to start a Korean day.
