A Korean bar classic : sweet corn blanketed with stretchy mozzarella, served bubbling in a hot skillet.

Pas encore de notes

A black skillet lands on the table sizzling; sweet corn kernels glisten with mayonnaise and butter, and a layer of golden mozzarella pulls into long strands the moment you dip in your chopsticks.

Korean corn cheese doesn’t aim for balance: it’s unabashedly sweet, creamy, and buttery. It’s the kind of snack you keep picking at with a cold beer in hand, never quite wanting to stop.

Another Korean snack that goes all in on cheese and crunch : the Korean corn dog.

Corn cheese: what is it ?

In Korea, it’s called kon-chijeu (콘치즈), less a Western-style gratin than a true bar snack. The base is simple and distinctly modern : canned sweet corn, mayonnaise, butter, a little sugar, and low-moisture mozzarella, the famous Korean “pizza cheese”.

The whole thing melts into a creamy, stretchy texture that browns without turning runny. It’s a staple of modern Korean cuisine, born in bars and restaurants rather than family kitchens.

It’s neither tangy nor spicy : no lime, no sprinkling of chili, which makes comparisons with Mexican elote misleading. Corn cheese stays firmly in a mild, milky register, and low-moisture mozzarella is what holds it all together : fresh mozzarella, with too much moisture, ruins the texture that makes the dish work.

How corn cheese came to be

The ingredients behind corn cheese came together under difficult circumstances. During and after the Korean War, American food surpluses introduced canned sweet corn, processed cheese, Spam, and sausages to the Korean market.

Like budae-jjigae, the dish grew out of that spirit of resourcefulness, but it took a different path : instead of ending up in a spicy broth, those ingredients kept their creamy, sweet character.

In the 1990s, especially in raw fish restaurants around Busan, a complimentary starter called “corn butter” was common : sweet corn sautéed in margarine with a generous amount of mayonnaise, browned by the heat.

Customers mistook that browned surface for cheese, and bars in Seoul’s Sinchon university district eventually added actual mozzarella, turning it into an anju, a snack served with alcohol. By 1999, cookbooks were already explaining how to make sweet corn au gratin with “pizza cheese” at home.

Looking for something bolder ? Kimchi jjigae plays the opposite card, fiery and tangy.

The rest came down to cheese availability. The rise of pizza delivery and the growth of Korean producers like Imsil Cheese in the late 1990s made low-moisture mozzarella affordable and easy to find. This exceptionally stretchy cheese gave the dish its current form : corn underneath, a golden bubbling layer on top, and strands you pull away with chopsticks.

The main ingredients in corn cheese

It all starts with canned sweet corn, dan-oksusu, whose tender, juicy kernels give the dish its signature sweetness. Drain it well, or the mixture will turn watery.

Traditional Korean corn, chal-oksusu, is stickier and firmer, needs extra sugar, and stays chewier : that’s not what we’re after here.

Mayonnaise ties the corn’s moisture to the dairy richness, adds a touch of acidity, and helps the surface brown. Ottogi Gold is the Korean benchmark, but many cooks prefer Kewpie for its deeper umami. Unsalted butter has replaced the margarine of the early days for its rounder flavor, and a little sugar, brown sugar, or sweetened condensed milk brings the signature sweet-savory balance.

Low-moisture mozzarella, “pizza cheese,” is the signature element : it melts into an even layer that blisters over high heat, while fresh mozzarella would release too much whey.

A finely chopped onion and a few diced red or green bell peppers bring the aroma and crunch found in restaurant versions. A pinch of MSG is optional, but especially useful with a milder Western-style mayonnaise.

The perfect match for soju and beer

Corn cheese belongs more to drinking culture than to the everyday table of rice and soup. You’ll find it in pojangmacha, bars, Korean barbecue restaurants, and raw fish restaurants, sometimes served in a skillet still bubbling hot.

Its sweetness and richness soften the sharp bite of soju and pair beautifully with an ice-cold lager.

To tame the heat of a fiery ramen, reach for a spoonful of corn cheese or a bowl of Buldak carbonara.

It also helps tame the burn of chili. The fat from the mozzarella, mayonnaise, and butter helps lift capsaicin from the palate, which explains why it pairs so well with spicy dishes like dakbal, jjukkumi, or Buldak noodles. It’s the same principle behind the popularity of Buldak carbonara and other spicy ramen topped with melted corn cheese.
