Korean Braised Monkfish: How Korea’s Ugliest Fish Became a Delicacy

The first time a plate of Korean braised monkfish lands on your table, you may quietly panic. It arrives as a glistening red mountain. Chunks of pale fish sit half-buried under a thick, chili-slicked sauce. A tangle of bean sprouts and water parsley crowns the whole thing. Steam rises off it, and the smell is sharp, garlicky, and unmistakably spicy. For many first-time visitors, this is the moment they realize Korean food is not going to play it safe.

Yet here is the twist that makes agujjim such a delight to discover. The star of this dish was, for most of its history, considered garbage. Fishermen once tossed monkfish back into the sea. Others ground it up for fertilizer. Nobody wanted it. Today, however, this same fish anchors one of Korea’s most beloved spicy dishes. It fills dedicated restaurant streets from the southern port of Masan up to the trendiest corners of Seoul. In other words, the ugliest fish in the harbor became a delicacy. And the story of how that happened tells you something about Korea itself.

This guide covers what a curious eater needs to know. We will look at what the fish actually is, why it carries the name of a “hungry ghost,” and how the dish was born. Most importantly, you will learn how to eat it without looking like a tourist. By the end, you should feel ready to walk into an agujjim restaurant and order like you belong there.

What Exactly Is Korean Braised Monkfish?

Let’s start with the basics. Agujjim (아구찜) is a spicy braised monkfish dish built around three core elements. First come the chunks of monkfish. Next comes a generous pile of soybean sprouts. Finally, a fiery paste of Korean chili flakes, garlic, ginger, and soybean products ties it together. The word jjim refers to braising or steaming. So agujjim is monkfish braised in a thick, clingy, aggressively seasoned sauce rather than a soup.

The fish itself deserves a proper introduction. Monkfish, sometimes called anglerfish, is a genuinely alarming creature. It has a massive flattened head, a cavernous mouth, and a body that tapers into a stubby tail. On the boat, it looks less like dinner and more like a nightmare. Beneath that grim exterior, though, the flesh is firm, white, and mild. In fact, the texture sits closer to lobster than to a delicate white fish. It holds its shape when braised, and it carries almost no fishy odor. That is precisely why it works so well under a heavy blanket of spice.

Nutrition is another pleasant surprise. Monkfish is remarkably lean. It delivers roughly 97 calories and more than 18 grams of protein per 100 grams, with only about 2 grams of fat. Those figures come from nutritional data compiled by Foodstruct. Furthermore, it is exceptionally rich in selenium and a solid source of vitamin B12 and phosphorus. As a result, agujjim feels indulgent while staying fairly guilt-free. That mix of bold flavor and lean protein is a big part of why the dish endures.

The Hungry Ghost: Where the Name Comes From

Now for the part that tends to stop foreign diners cold. The Korean word for monkfish, agwi (아귀), is not a neutral fish name. It comes from Buddhist cosmology. There, agwi (餓鬼) means “hungry ghost,” a tormented spirit condemned to eternal, unsatisfiable hunger. In Buddhist belief, these ghosts inhabit a lower realm. They suffer forever because a huge appetite meets a needle-thin throat.

Once you understand the fish, the name makes perfect, gruesome sense. Monkfish are ambush predators with a bottomless appetite. When fishermen slice one open, they routinely find its stomach crammed with whole, undigested fish. In effect, Koreans looked at this greedy, gaping creature and named it after a demon from hell. For a foreign reader, few dishes come with an origin story this vivid. You are, quite literally, eating the “hungry ghost fish.”

This is also a good example of why context matters in Korean cuisine. A name that sounds like pure folklore actually encodes sharp observation about the animal’s behavior. Korea does this a lot. Learning to read those hidden layers turns eating into something closer to storytelling. If you enjoy that kind of decoding, it pairs naturally with brushing up on Korean dining etiquette before you sit down.

From Trash Fish to Treasure: The Masan Origin Story

Here the humble-origins theme really takes hold. For generations, Korean fishermen regarded the monkfish as worthless. It was ugly, it was slimy, and it had no market value. Consequently, they either threw it back or used it as fertilizer on rice paddies. The fish that now commands its own restaurant streets was, not so long ago, left to rot in a field.

The transformation began in the southern port city of Masan, now part of Changwon, in the mid-1960s. As the story goes, local fishermen brought their unwanted monkfish to cooks at the market eateries. They asked for something edible in return. Necessity, in other words, did the inventing. The cooks leaned on what they had in abundance. That meant dried monkfish, plentiful soybean sprouts, and a pantry full of chili and garlic. The result was a bold, chewy, intensely flavored braise. You can read a fuller account on Wikipedia’s entry for agwi-jjim, which traces the dish from discarded catch to regional pride.

Masan’s fishermen had stumbled onto something bigger than a recipe. Fish stocks tightened through the late twentieth century. Once-common species grew scarce and expensive. Meanwhile, the formerly disposable monkfish climbed steadily in status and price. What began as a way to avoid waste became a genuine delicacy. Today the dish sits alongside Korea’s other great working-class success stories. It shares the same underdog energy that powers everything from the kimchi stew business to the country’s booming K-Food exports. Korea has a real talent for turning the humble into the iconic.

Masan Style vs. Seoul Style: Two Ways to Braise a Monkfish

Not all agujjim is created equal. Knowing the difference will sharpen your ordering instantly. There are two dominant styles, and they hinge on one deceptively simple question. Fresh fish, or dried?

Masan style is the original, and it insists on dried monkfish. In the traditional method, the fish is hung and air-dried for two weeks to a month before cooking. Drying concentrates the flavor. It also produces a firmer, chewier texture that clings beautifully to the sauce. Purists argue that this is the only real agujjim. As a result, Masan-style spicy monkfish stew tends to taste deeper and more savory. The dried fish also lends a rustic, old-school character that reflects the dish’s port-city roots.

Seoul style, by contrast, generally uses fresh monkfish. The fish is gutted and braised without the long drying process. This version yields a softer, more tender bite and a cleaner, brighter flavor. Because fresh fish is easier to source in a big city, it dominates the capital’s restaurants. Neither style is objectively better. They simply appeal to different palates. That said, try Masan monkfish prepared the traditional dried way at least once. It is the dish as originally conceived.

Regional pride runs deep here. The same holds for other Korean specialties tied tightly to a single place. Exploring these local food identities is half the fun of traveling beyond the capital. You might chase agujjim in Changwon, or hunt down the specialties in our Daegu travel guide.

How to Actually Eat Korean Braised Monkfish

So the plate has arrived. It is enormous, and it is glowing red. What now? Eating agujjim well is a small art, and getting it right transforms the meal.

First, understand the supporting cast. The mound of soybean sprouts (kongnamul) is not a garnish. It is essential. The sprouts are usually parboiled and chilled separately so they stay crisp. Then they are folded in at the end. Their fresh crunch and mild, nutty flavor cut cleanly through the heat. Similarly, ribbons of minari (water parsley) add a bright, herbal note. Some restaurants also include mideodeok, a briny sea squirt that bursts with ocean flavor. Each element is there for balance. So make sure every bite includes a little of everything, not just the fish.

Second, respect the heat but plan for it. Agujjim is genuinely spicy. The sauce is built on Korean red chili flakes and a heavy dose of garlic, and it does not hold back. Therefore, keep your rice close. The traditional move is to eat the fish and sauce alongside plain white rice. Each spoonful tempers the burn and soaks up the flavor. If your table orders soju, you will quickly see why agujjim is such a celebrated anju, or drinking companion. The cold, clean spirit balances the fire nicely.

Third, save room for the grand finale. In most agujjim restaurants, the staff will offer bokkeumbap once the fish is gone. This is fried rice cooked directly in the leftover sauce, right at your table. Spiritually, it is not optional. The rice fries up in all that concentrated chili-and-garlic goodness. A crispy bottom layer forms, and for many regulars it is the single best part of the meal. Whatever you do, do not leave before the fried rice.

How Spicy Is Agujjim, Really? A Heat Guide for First-Timers

Newcomers always ask the same question. How hot is this spicy monkfish stew, honestly? Well, the answer depends on your baseline. For a diner used to mild food, the dish lands firmly in the “memorable” range. For a chili veteran, however, it reads as pleasantly warm rather than brutal.

Here is some useful context. The heat comes almost entirely from gochugaru, the Korean red chili flakes. Unlike raw chili or vinegary hot sauce, gochugaru brings a rounded, smoky warmth instead of a sharp sting. Consequently, the spice builds slowly and stays manageable. Moreover, the sauce carries plenty of garlic and savory depth. Heat, in other words, is never the only thing you taste.

Still, a few smart moves keep things comfortable. First, alternate every bite of fish with a mouthful of rice. Second, lean on the soybean sprouts, since their cool crunch resets your palate. Third, order a side of soup or a soft drink for extra insurance. As a result, even spice-shy eaters can usually finish a plate without regret.

One more tip is worth knowing. If you truly cannot handle heat, ask whether the kitchen can dial it down. Many restaurants will happily adjust the chili for foreign guests. Alternatively, order agutang, the soupier cousin, which spreads the same flavor across a gentler, brothier base. Either way, nobody should skip agujjim simply out of fear of the spice.

The Monkfish Liver Secret: Korea’s Answer to Foie Gras

Here is a detail that separates casual eaters from true agujjim enthusiasts. Beyond the firm white flesh, the monkfish hides a genuine luxury. Its liver is prized across both Korea and Japan. Diners often describe it as a natural rival to foie gras. It is silky, rich, and deeply savory, with a comparable sense of indulgence.

There is even an ethical dimension to the comparison. Foie gras is produced by force-feeding ducks and geese. As a result, it has drawn sustained criticism on animal-welfare grounds. Monkfish liver, on the other hand, is simply harvested from a fish that lives an ordinary life on the seafloor. Some diners therefore frame it as the more humane way to enjoy that buttery mouthfeel. You may occasionally find it served on its own or in higher-end preparations. If a menu offers it, it is well worth trying.

This nose-to-tail thinking runs throughout traditional Korean cooking. Nothing on the fish goes to waste. It is the same resourceful instinct that turned a discarded catch into a celebrated dish. Moreover, it connects agujjim to the broader story of how Korean cuisine keeps reinventing itself on the global food market.

Where to Try It: Masan and Seoul

If you want the authentic pilgrimage, all roads lead to Masan. The city’s famous Masan Agujjim Street (마산 오동동 아구찜거리) sits in the Odong-dong area of Masanhappo-gu, in Changwon. It is the spiritual home of the dish. Here, dozens of long-running restaurants specialize in the traditional dried-monkfish style. Eating agujjim within sight of the harbor that invented it is about as authentic as it gets. The Korea Tourism Organization keeps a helpful overview on its official VisitKorea site, with directions and background.

For most travelers, however, Seoul will be the easier place to start. The capital has its own well-established agujjim clusters. The densest concentrations sit around Sinsa-dong and the Jongno district. These restaurants tend to lean toward the fresh, tender Seoul style, and many have served the dish for decades. Guides like this Insadong agujjim writeup from Creatrip can point you toward long-standing favorites near the main tourist areas.

A quick word on price and portions. Agujjim is almost always sold as a shared dish sized for two or more. Therefore, it is best enjoyed with company. Portions run generous, and prices stay reasonable for the amount of food. The shared format makes it a natural centerpiece for a group dinner. Dining solo? A bowl of agutang, the soupier and milder cousin of the dish, is often the friendlier single-serving option.

A few practical notes will smooth the visit. Typically, the fish is priced by size, so a “small” easily feeds two hungry people. In addition, most restaurants serve a spread of free side dishes, or banchan, alongside the main plate. Furthermore, the bokkeumbap finale usually costs just a little extra, and it is worth every won. Meanwhile, popular spots can fill up fast on weekends, so an early dinner is often the smarter play.

The Verdict for First-Timers

So, should you order the hungry ghost fish? Absolutely, with a little preparation. Korean braised monkfish rewards the adventurous eater like few dishes in the country. It is spicy, yes. But the heat is purposeful rather than punishing. The interplay of chewy fish, crunchy sprouts, herbal parsley, and cooling rice creates a genuinely layered experience. Add the table-side fried rice at the end, and you have a meal that feels like an event.

More than that, agujjim carries a story worth chewing on. In a single plate, you get Buddhist folklore and a rags-to-riches origin tale. You also get a clever bit of resourcefulness and a regional rivalry between two proud cities. Few dishes anywhere pack that much narrative into a shared bowl. When you eat it, you taste the same ingenuity that keeps Korean food winning fans far beyond its borders. That theme runs through so much of what makes the country’s cuisine tick.

In the end, the ugliest fish in the harbor became one of Korea’s finest meals. All it took was a little imagination, a lot of chili, and the willingness to look past a monstrous face. So come hungry, keep the rice close, and do not, under any circumstances, skip the fried rice.
