Don’t Miss These Foods in Korea #50. Perilla Oil Makguksu: The Korean Noodle Dish Foreigners Suddenly Can’t Stop Talking About

When most foreigners think about Korean food, they usually imagine something bold and intense first — spicy tteokbokki, sizzling Korean BBQ, fiery ramyeon, or kimchi stew packed with strong flavors.

But recently, a very different kind of Korean dish has quietly become popular among international travelers visiting Seoul.

It is not spicy.
It is not flashy.
It does not come with giant portions of meat or dramatic toppings.

In fact, many foreigners look at it for the first time and think:

“That’s it?”

And then, surprisingly, they cannot stop thinking about it afterward.

That dish is Perilla Oil Makguksu (Deulgireum Makguksu) — Korean buckwheat noodles mixed with fragrant perilla oil, soy sauce, roasted seaweed, and sesame seeds.

Over the past few years, this simple noodle dish has become increasingly popular among:

• solo travelers in Seoul
• international students in Korea
• food-focused travelers
• wellness food enthusiasts
• minimal food aesthetic creators on TikTok and Instagram

Especially in trendy Seoul neighborhoods like Seongsu, Bukchon, Ikseon-dong, and Mangwon, it is now common to see foreign visitors lining up at famous makguksu restaurants.

And interestingly, the reason foreigners love this dish is not because it is dramatic.

It is because it feels unexpectedly calm, balanced, and comforting.

What Is Perilla Oil Makguksu?

Makguksu is a traditional Korean buckwheat noodle dish originally associated with Gangwon Province, a mountainous region in northeastern Korea.

Because the climate there was historically better for growing buckwheat than rice, buckwheat-based dishes naturally became an important part of the local food culture.

Traditional makguksu is usually served:

• in a cold broth made with dongchimi (radish water kimchi), or
• mixed with spicy seasoning sauce.

But modern Seoul-style Perilla Oil Makguksu takes a very different approach.

Instead of strong spice or heavy broth, the dish focuses on:

• roasted perilla oil
• chewy buckwheat noodles
• roasted seaweed
• soy sauce
• sesame or perilla seeds

At first glance, it almost looks too simple.

But that simplicity is exactly what makes it memorable.

Why Are Foreigners Suddenly Obsessed With It?

1. It Fits the Global Wellness Food Trend

One reason this dish has become so popular among foreigners is that it matches current global food trends perfectly.

Around the world, more people are searching for:

• healthy Korean food
• plant-forward meals
• light noodle dishes
• clean eating
• minimalist cuisine
• slow food culture

Perilla Oil Makguksu naturally fits into all of those categories.

The ingredients are relatively simple and feel less processed compared to many modern fast-food dishes.

For many foreign travelers, especially those coming from Europe or North America, the dish feels like:

“Korean comfort food without heaviness.”

After several days of spicy food, fried chicken, and barbecue, many visitors start looking for something lighter and easier on the stomach.

That is often when Perilla Oil Makguksu becomes unforgettable.

2. It Completely Changes Their Image of Korean Food

Many foreigners arrive in Korea expecting every Korean dish to be:

• spicy
• heavily seasoned
• strong
• fermented
• extremely intense

But Perilla Oil Makguksu feels completely different.

It is subtle.

Instead of aggressive spice, the dish focuses on:

• aroma
• texture
• balance
• ingredient quality

The flavor develops slowly rather than hitting immediately.

That is why many foreigners say things like:

“I didn’t know Korean food could taste this delicate.”

Or:

“It’s strangely addictive.”

Interestingly, people often do not fully appreciate the dish during the first bite.

Instead, they think about it later.

Many travelers mention that one or two days after eating it, they suddenly crave it again.

That lingering memory is one of the reasons the dish has become so popular among foreign visitors in Seoul.

The Most Important Part of the Dish Is the Aroma

Perilla Oil Makguksu is not really about sauce.

It is about aroma.

Foreigners often compare perilla oil to sesame oil, but the flavor is actually quite different.

Sesame oil is:

• rich
• familiar
• strongly nutty

Perilla oil, on the other hand, feels:

• earthier
• deeper
• more herbal
• slightly roasted
• more calming

Many foreign visitors struggle to describe it at first because it does not taste exactly like anything common in Western cuisine.

That unfamiliar aroma becomes part of the experience.

And for many travelers, it becomes one of the most uniquely “Korean” flavors they encounter during their trip.

Why Younger Koreans Love It Too

Interestingly, Perilla Oil Makguksu is not just popular among tourists.

In Seoul, younger Koreans also actively search for famous makguksu restaurants.

Especially in neighborhoods like:

• Seongsu
• Euljiro
• Ikseon-dong
• Mangwon
• Hannam-dong

many modern Korean restaurants now serve stylish versions of Perilla Oil Makguksu.

Young Koreans often see it as:

• a clean lunch menu
• a light comfort food
• modern Korean cuisine
• a more refined style of Korean dining

In many ways, the dish reflects the recent direction of Korean food culture itself.

Instead of focusing only on stronger flavors or larger portions, more people are now appreciating:

• ingredient quality
• balance
• aroma
• simplicity
• traditional ingredients used in modern ways

Perilla Oil Makguksu represents that trend perfectly.

Perilla Oil Makguksu, one of Seoul’s trending Korean noodle dishes, highlights the deep aroma of perilla oil, chewy buckwheat noodles, and the minimalist beauty of modern Korean food culture.

How Koreans Actually Eat It

One mistake many foreigners make is treating Perilla Oil Makguksu like cold Japanese soba or naengmyeon.

Koreans usually eat it a little differently.

First, do not add vinegar immediately

Many restaurants provide vinegar and mustard on the table, but locals usually try the original flavor first.

The aroma of the perilla oil is the most important part of the dish.

Second, mix the noodles thoroughly

The soy sauce and oil often settle at the bottom of the bowl.

Koreans usually lift the noodles from the bottom several times to evenly coat everything.

Third, eat it together with kimchi

This is important.

The refreshing acidity of kimchi balances the nutty richness of the perilla oil surprisingly well.

Many foreigners realize this only after trying both together.

Finally, add vinegar or mustard later

After eating about half the bowl, many Koreans add a small amount of vinegar or mustard to slightly change the flavor profile.

It almost feels like eating two different dishes in one bowl.

Why Solo Travelers Love It

Another reason Perilla Oil Makguksu is becoming popular among foreigners is that it works perfectly for solo dining in Korea.

Many travelers feel uncomfortable eating alone at:

• Korean BBQ restaurants
• drinking-focused restaurants
• large group dining places

But makguksu restaurants are usually:

• casual
• quiet
• fast
• affordable
• comfortable for solo visitors

In neighborhoods like Seongsu or Bukchon, it is now very common to see foreign solo travelers quietly enjoying a bowl of Perilla Oil Makguksu during lunch.

And somehow, that atmosphere fits the dish perfectly.

What Koreans Usually Eat With Makguksu

In Korea, makguksu is often enjoyed together with:

• suyuk (boiled pork slices)
• gamjajeon (crispy potato pancake)
• buckwheat pancakes

Especially with Perilla Oil Makguksu, crispy potato pancakes create a surprisingly good balance.

The noodles feel light and nutty, while the potato pancake adds warmth and texture.

This combination is especially popular during rainy weather or relaxed weekend lunches in Korea.

Why This Dish Stays in People’s Memories

Perilla Oil Makguksu is a very quiet dish.

There is no dramatic presentation.
No overpowering spice.
No heavy broth.
No excessive toppings.

But because the dish is so simple, every ingredient matters.

You can immediately notice:

• the quality of the buckwheat noodles
• the aroma of the perilla oil
• the balance of the soy sauce
• the umami from the roasted seaweed

A good bowl of Perilla Oil Makguksu feels:

• light but satisfying
• simple but deep
• comforting without being heavy

And perhaps that is exactly why so many foreigners remember it long after leaving Korea.

It represents a side of Korean food culture many travelers do not expect:
quiet, balanced, ingredient-focused, and deeply comforting.

If you want to experience a more modern, subtle, and locally loved side of Korean cuisine during your trip to Seoul, Perilla Oil Makguksu is absolutely worth trying.

It may look simple at first.

But there is a very high chance it will become one of the Korean dishes you remember the longest.
