Mandu — Korean Dumplings From Scratch (Easier Than You Think)

What is Mandu?

Mandu (만두) are Korean-style dumplings — close cousins of Chinese jiaozi, but with their own personality. The fillings are richer (often kimchi, pork, and tofu together), and the wrappers are usually a touch thicker, designed to hold up to pan-frying or being tossed into stews.

Korean families traditionally make hundreds at a time — a Sunday afternoon ritual where everyone sits around the table, fills, folds, and freezes. One session = months of dinners. There’s no Korean food more bang-for-effort than mandu.

This is the home version — manageable for one cook in 90 minutes, yielding about 40 dumplings.

Ingredients (Makes ~40 dumplings)

The wrappers

1 pack store-bought mandu wrappers (about 40 sheets) — round, about 8 cm diameter

Korean grocery stores: look for “Mandu Pi” or “만두피” in the refrigerated section. Don’t substitute with thinner gyoza wrappers — they tear.

The filling

300g (10 oz) ground pork
200g (7 oz) firm tofu, drained and crumbled
1.5 cups well-fermented kimchi, finely chopped, juice squeezed out
150g (5 oz) bean sprouts, blanched 1 min, drained, finely chopped
2 stalks green onions, finely chopped
1 small onion, finely diced

Filling seasoning

2 tablespoons soy sauce
1 tablespoon sesame oil
1 tablespoon toasted sesame seeds
3 cloves garlic, minced
1 teaspoon ginger, grated
1 teaspoon sugar
1 teaspoon salt
1 teaspoon black pepper

Dipping sauce

3 tablespoons soy sauce
1 tablespoon rice vinegar
1 teaspoon sesame oil
1 teaspoon gochugaru (optional, for kick)
1 teaspoon sesame seeds

Step 1. Prep the filling components

The key to good mandu filling is moisture control. Wet filling = soggy dumplings = sad cook.

Tofu: Wrap the tofu in a clean towel and press hard for 10 minutes to remove water. Crumble.

Bean sprouts: Blanch 1 minute in boiling salted water. Drain, rinse cold, and squeeze with both hands to wring out water. Finely chop.

Kimchi: Squeeze the juice out (save it for kimchi jjigae!). Finely chop.

Onion: Finely dice. Sprinkle with 1/2 tsp salt, let sit 10 minutes, squeeze out water.

This step looks tedious but adds up to maybe 15 minutes total.

Step 2. Mix the filling

In a large bowl, combine ground pork, tofu, kimchi, bean sprouts, onion, green onions with all the seasoning ingredients.

Mix with hands — wear gloves — for at least 2 minutes until everything is uniform and slightly sticky. The mixture should hold together when you press it.

Test the seasoning: heat a small pan, cook a thumb-sized portion until done. Taste. Adjust salt/soy sauce as needed before filling 40 dumplings.

Pro tip: The filling should taste slightly salty and bold on its own, because the wrapper is bland and dilutes flavor.

Step 3. Fill the dumplings

Set up your station:

A wrapper pack on the side
A small bowl of water (for sealing)
The filling bowl
A tray dusted with flour or lined with parchment

Working with one wrapper at a time:

Hold the wrapper in your palm.
Place 1 heaping teaspoon of filling in the center. Don’t overfill — wrappers tear.
Dip a finger in water, run it along the edge of the wrapper.
Fold in half to form a half-moon. Pinch the center first, then work outward, pressing out air as you seal.
Optional: pleat the edges by folding small tucks (5–6 pleats) along one side. This makes them look professional. Beginner pleats are fine — taste is the same.
Place sealed dumplings on the tray, not touching each other.

Pace: about 1 dumpling every 30 seconds once you find your rhythm. 40 dumplings = ~25 minutes of folding.

Step 4. Cook (3 ways to choose from)

Way 1: Pan-fried mandu (Yaki Mandu / Gun Mandu)

Heat 2 tbsp oil in a non-stick pan over medium heat.

Place dumplings flat-side down in the pan, not touching. Fry for 2 minutes until the bottoms are golden brown.

Add 1/3 cup water to the pan and immediately cover with a lid. Steam for 5 minutes.

Remove the lid. Let the water evaporate for another 1–2 minutes until the bottoms re-crisp.

Result: golden crisp bottom, tender steamed tops. The most popular way to eat mandu.

Way 2: Boiled mandu (Mul Mandu)

Bring a pot of salted water to a boil. Drop in dumplings (don’t crowd). Boil for 6–8 minutes — they’ll float when ready, then cook for 1 more minute.

Drain. Drizzle with sesame oil. Soft, juicy, classic.

Way 3: Mandu Guk (Mandu in Soup)

The ultimate winter dish. Bring 4 cups beef or anchovy stock to a simmer. Drop in 8 dumplings. Cook 6 minutes. Add a beaten egg in a slow drizzle for “egg ribbons.” Top with seaweed and green onions.

Step 5. Make the dipping sauce

Mix all dipping sauce ingredients in a small bowl. Done.

Each dumpling = a dunk in the sauce, then to mouth.

Freezing and Storage

This is where mandu shines. Freeze raw dumplings on the tray (not touching) for 2 hours, then transfer to a zip-bag.

Freezer life: up to 3 months
Cooking from frozen: don’t thaw. Add 2 extra minutes to cooking time.

A bag of frozen mandu in your freezer = 5 dinners ready in 10 minutes.

Common Mistakes

Soggy filling: didn’t squeeze enough water out of vegetables. Be ruthless.

Wrappers tear: too much filling, or wrappers got too dry. Keep extras under a damp towel while folding.

Filling falls out while cooking: poor seal. Press edges firmly with a wet finger, double-check the center pinch.

Bland filling: didn’t taste-test. Always cook a tester before mass production.

Variations

Vegetarian mandu: skip pork, double the tofu, add chopped shiitake mushrooms (rehydrated dried ones work great).

Beef mandu: substitute ground beef for pork. Add 1 extra tablespoon of soy sauce.

Cheese mandu: in each wrapper, add a small cube of mozzarella alongside the filling. Modern Korean comfort food.

Bigger or smaller: the same filling works in jumbo (15 cm) wrappers for “wang mandu” (steamed buns) or in tiny wrappers for soup.

Final Thoughts

Mandu is the perfect dish to make with friends or family. Set up a folding line on a Sunday afternoon, put on a movie, fold while you watch. Two hours later, you have 80 dumplings — half for dinner, half in the freezer for winter.

It’s the closest thing Korean cooking has to investment with compound interest. A single afternoon = weeks of weeknight dinners that take 10 minutes from freezer to plate.
