What Is Mandu? Korea's Dumpling Tradition Explained

Mandu (만두) are Korean dumplings — filling enclosed in a thin wrapper, then cooked by steaming, boiling, pan-frying, or deep-frying. They share broad ancestral similarity with Japanese gyoza and Chinese jiaozi, and the word itself derives from the Chinese mantou (which now refers to unfilled steamed buns in China, though the original meaning was filled dumplings).

Korean mandu have their own distinct tradition: specific filling profiles, cultural contexts, and a variety of forms that differ from their Chinese and Japanese relatives.

A Brief History

Mandu arrived in Korea through Chinese influence, likely during the Goryeo Dynasty (918-1392) through trade and cultural exchange with the Yuan Dynasty. The earliest written Korean record of mandu dates to the late Goryeo period.

Through the Joseon Dynasty, mandu was eaten widely but had specific ceremonial significance: tteokguk (rice cake soup) made with mandu (called tteok mandu-guk) became associated with Seollal (Lunar New Year), where eating it was believed to add a year to one's age. This New Year's mandu soup tradition persists.

During the Japanese colonial period (1910-1945) and the Korean War (1950-1953), mandu were both a common food and a survival food — simple, filling, adaptable to whatever ingredients were available.

Types of Mandu

By Cooking Method

Jjin mandu (찐만두) — Steamed: Placed in a bamboo steamer over boiling water, cooked 10-12 minutes. The wrapper becomes soft and slightly translucent. The juiciest version — no fat added in cooking, all moisture comes from the filling.

Mandu-guk (만둣국) — Boiled in soup: Mandu dropped directly into soup broth and simmered. Most common in tteok mandu-guk (rice cake and dumpling soup). The mandu absorb the soup flavor; the broth absorbs some filling richness.

Gunmandu (군만두) — Pan-fried: The most widely eaten version outside Korea. Same technique as Japanese gyoza — water added to the pan after initial frying to steam the tops while the bottoms crisp. Produces the characteristic crispy bottom with soft, juicy top.

Twigim mandu (튀김만두) — Deep-fried: Mandu deep-fried until golden. Served as a snack or street food. Crispier than pan-fried, somewhat drier filling.

By Shape

Gyo-ja shape (교자 모양): Crescent-folded, similar to Japanese gyoza. Pleated along one edge. The most common commercial form.

Pyeonyuk mandu (편육만두): Square-wrapped, similar to Chinese wonton shape.

Gom mandu (곰만두): Large, round, sealed like a parcel — "bear mandu," sometimes called because the large round shape resembles a bear. Used for soup applications.

Wang mandu (왕만두): "King mandu" — very large, about twice the size of regular mandu. Traditionally steamed.

The Filling

Korean mandu filling differs from Japanese gyoza in several ways:

Classic Korean mandu filling:

• Pork (medium-fat ground pork or a mixture of pork and beef)
• Tofu (pressed dry and crumbled) — much more tofu relative to meat than Japanese gyoza
• Glass noodles (dangmyeon, sweet potato starch noodles) — soaked and chopped
• Kimchi (optional but common) — squeezed dry
• Onion, garlic, ginger
• Green onion
• Sesame oil
• Soy sauce, salt

The role of tofu: Korean mandu filling often contains 1:1 ratio of tofu to meat or more, making it lighter and less fatty than Japanese gyoza. The tofu must be pressed very dry or the filling will be wet and the wrapper will tear.

The role of dangmyeon: Glass noodles add texture and help bind the filling without adding strong flavor. This is distinctly Korean — Japanese gyoza don't use glass noodles.

Kimchi mandu: A common variation where well-fermented kimchi (squeezed dry to remove excess liquid) replaces some of the filling or serves as the primary filling alongside tofu and pork. The fermented flavor permeates the whole dumpling during cooking.

Vegetarian mandu: Made with tofu, glass noodles, and vegetables only — common for the Seollal New Year preparations, especially in temple food contexts.

Making Mandu at Home

The filling:

• 200g ground pork
• 200g firm tofu, pressed very dry and crumbled
• 50g soaked and chopped dangmyeon glass noodles
• 100g well-squeezed kimchi, minced (optional)
• 3 green onions, minced
• 3 cloves garlic, minced
• 1 tablespoon sesame oil
• 1 tablespoon soy sauce
• Salt and white pepper to taste

Combine all ingredients. Test seasoning by cooking a small amount in a pan. The filling should taste slightly over-seasoned raw — it will mellow during cooking.

The wrapper: Commercial mandu wrappers (sold refrigerated at Korean and most Asian grocery stores) are slightly thicker than gyoza wrappers — use them directly. Or use gyoza wrappers, which are thinner and produce a more delicate result.

Folding: Place filling in center. Wet wrapper edge. Fold into crescent. Pleat 3-5 times along the curved edge to seal. Press firmly. The pleat is functional, not decorative — it prevents opening during cooking.

Pan-frying (gunmandu): Heat 2 tablespoons neutral oil in a large skillet over medium-high heat. Place mandu flat side down. Cook 2-3 minutes until bottoms are golden brown. Add 75ml water. Cover immediately — the steam will spit. Cook covered 5-6 minutes until water evaporates. Remove cover, cook 30 seconds to re-crisp. Serve immediately with dipping sauce.

Dipping sauce: 2 tablespoons soy sauce + 1 tablespoon rice vinegar + 1 teaspoon sesame oil + pinch of gochugaru (optional). Simple and effective.

Tteok Mandu-guk: New Year's Soup

The most culturally significant mandu preparation is tteok mandu-guk — a soup combining oval rice cakes (tteok) and mandu in a beef or anchovy broth.

Eating tteok mandu-guk at Seollal (Lunar New Year) is one of Korea's most consistent food traditions. The white oval rice cake represents the bright new year; the mandu is added to make the soup more filling and festive.

Simple tteok mandu-guk:

1. Make a beef broth by simmering thinly sliced beef (brisket or sirloin) in water with garlic and green onion for 20 minutes. Season with soy sauce and salt.
2. Add sliced garaetteok (oval rice cakes, soaked 30 minutes) to the broth. Simmer 5 minutes.
3. Add fresh or frozen mandu. Simmer 5-7 minutes.
4. Ladle into bowls.
5. Top with a thin egg sheet (jidan) cut into strips, dried seaweed (gim) strips, and sliced green onion.

Mandu occupies a specific position in Korean food culture that gyoza doesn't in Japanese culture: they're both casual everyday food AND ceremonially significant food (the New Year connection). Understanding this dual role — street snack and ancestor ritual food — captures something of the depth that Korean food culture attaches to what looks like a simple dumpling.
