Korean Mandu: Pan-Fried Pork and Vegetable Dumplings

Korean mandu are savory dumplings filled with seasoned meat, tofu and vegetables, then steamed, boiled or pan-fried. This recipe makes crisp-bottomed, tender pork mandu served with a tangy soy-vinegar dipping sauce; fillings and cooking styles vary across Korean homes and regions.

Ingredients

8 oz (225 g) ground pork
4 oz (115 g) firm tofu, drained and crumbled
1 cup (70 g) finely shredded napa cabbage
1/2 cup (55 g) finely chopped shiitake or cremini mushrooms
2 scallions, finely sliced (about 1/4 cup or 25 g)
1/2 cup (40 g) mung bean glass noodles, dry
2 cloves garlic, minced (about 2 tsp or 6 g)
1 tbsp (15 ml) soy sauce
1 tsp (5 ml) toasted sesame oil
1/2 tsp (1 g) fine salt
1/4 tsp (0.5 g) ground black pepper
30 round mandu wrappers, about 3 1/2 in (9 cm) wide, thawed if frozen
2 tbsp (30 ml) neutral oil, divided, for frying
1/2 cup (120 ml) water, divided, for steaming
For dipping sauce: 3 tbsp (45 ml) soy sauce, 1 tbsp (15 ml) rice vinegar, 1 tsp (5 ml) toasted sesame oil, and 1 tsp (3 g) toasted sesame seeds; optional 1/4 tsp (0.5 g) gochugaru

Instructions

Soak the glass noodles in hot water according to the package directions, usually 5–7 minutes, until pliable. Drain well, cool briefly, then chop into pieces about 1/4 in (6 mm) long. Keep this active preparation time within the 45-minute prep estimate.
Put the cabbage in a bowl with a pinch of the measured salt and let it stand for 10 minutes. Squeeze firmly over the sink or through a clean towel to remove excess liquid. This helps keep the filling from turning watery.
In a large bowl, combine the pork, crumbled tofu, squeezed cabbage, mushrooms, scallions, chopped noodles, garlic, soy sauce, sesame oil, remaining salt and pepper. Mix until evenly combined, but do not overwork it. Cook a small spoonful in a skillet if you want to check the seasoning before filling the wrappers.
Set a wrapper on a clean surface and place about 1 tablespoon (15 g) of filling in the center. Moisten half of the wrapper’s edge with water, fold it over the filling and press the edges together to seal, pushing out air pockets. Make pleats if you like, or leave the dumpling half-moon shaped. Keep unused wrappers covered with a damp towel so they do not dry out.
To pan-fry in batches, heat 1 teaspoon oil in a large nonstick skillet over medium heat. Arrange dumplings flat-side down without crowding and fry for 2–3 minutes, until the bottoms are golden. Carefully pour in 2 tablespoons water and cover immediately; steam for 5–7 minutes. Remove the lid and cook another 1–2 minutes so the water evaporates and the bottoms crisp again. Cook in batches, adding more oil and water as needed.
Check the center of a dumpling with a food thermometer; the pork filling must reach the USDA FSIS safe minimum of 160°F (71°C). If it has not reached that temperature, add a little water, cover and continue steaming, then check again. Mix the dipping-sauce ingredients in a small bowl while the dumplings cook.
Serve the mandu hot with the dipping sauce. If cooking all 30 dumplings in batches, keep finished ones loosely covered and serve promptly; do not leave them at room temperature for more than 2 hours.

Tips

Drain the tofu and squeeze the salted cabbage thoroughly. Excess moisture can split wrappers and make the filling loose.
Seal each dumpling well and remove trapped air. If a wrapper tears, patch it with a small piece of another wrapper moistened with water.
Round mandu wrappers are sold frozen or refrigerated in many Asian grocery stores. If unavailable, round gyoza wrappers work, though they may be slightly thinner; thaw frozen wrappers in the refrigerator before separating.
Mung bean glass noodles add a springy texture. If you cannot find them, use an equal amount of cooked, finely chopped vermicelli; the texture will be softer and less chewy.

Serving Suggestions

Serve mandu as a snack, appetizer or part of a Korean-style meal. Pair them with steamed rice, kimchi, seasoned spinach or a light soup such as miyeok-guk. The dipping sauce is deliberately sharp and salty; add a little water if you prefer it milder, or extra vinegar for more tang.

Variations

For a beef version, replace the pork with 8 oz (225 g) ground beef and cook the filling to 160°F (71°C). For a meat-free filling, omit the pork and use an extra 6 oz (170 g) drained tofu plus 1/2 cup (50 g) finely chopped cabbage or mushrooms; sauté the vegetables first and cool them before mixing. For a kimchi variation, replace 1/2 cup (70 g) of the cabbage with finely chopped, well-drained kimchi, reducing the added salt because kimchi is already seasoned. Mandu can also be boiled in gently simmering water until floating and cooked through; check a dumpling’s filling with a thermometer rather than relying on floating alone.

Storage and Reheating

Refrigerate cooked mandu within 2 hours in a covered container and use within 3–4 days. Reheat in a covered skillet with a splash of water until steaming hot, then uncover to recrisp the bottoms; leftovers should reach 165°F (74°C). A microwave also works, though the wrappers will be soft. Freeze uncooked dumplings in a single layer until firm, then transfer to a freezer bag and cook from frozen, adding several minutes to the covered steaming time. Do not thaw frozen dumplings at room temperature.

Frequently Asked Questions

Can I make mandu ahead?
Yes. Shape them up to a day ahead, arrange in a single layer on a parchment-lined tray, cover and refrigerate. Cook them within 24 hours, or freeze them for longer storage.

Why are my dumplings opening in the pan?
Common causes are wet filling, overfilling, dry wrapper edges or trapped air. Squeeze the vegetables dry, use about 1 tablespoon filling per wrapper and press the seam firmly closed.

Can I cook mandu from frozen?
Yes. Do not thaw first. Brown the frozen dumplings in oil, add water carefully and cover; expect the steaming stage to take a few minutes longer. Confirm the pork reaches 160°F (71°C) at the center.

Can I boil these instead of pan-frying?
Yes. Lower them into gently boiling water in batches and stir carefully once so they do not stick. Simmer until cooked through, then check the filling temperature; boiling produces soft wrappers rather than crisp bottoms.

What can I use instead of tofu?
Use an equal weight of finely chopped, sautéed mushrooms or extra drained cabbage. Tofu gives the filling a tender, mild texture, so the substitute will make the dumplings more vegetable-forward.

Are mandu and Chinese dumplings the same?
Mandu are Korean dumplings, while dumplings across East Asia have related but distinct fillings, wrappers and customary preparations. Korean versions may include ingredients such as tofu, kimchi or glass noodles, with many regional and household variations.
