What is Japchae?

WHAT IT IS

Japchae is sweet potato glass noodles (dangmyeon) tossed with stir-fried vegetables, mushrooms and beef in a sweet soy and sesame sauce. It is a fixture at birthdays, holidays and feasts.

WHERE IT COMES FROM

The name means “mixed vegetables,” and the oldest recipe, in the cookbook Eumsik Dimibang from around 1670, has no noodles at all: just stir-fried vegetables, mushrooms and pheasant under a thick sauce. In the early 1600s the official Yi Chung was mocked as the “japchae minister,” because his rise to Minister of Taxation was said to be owed to the dishes he sent King Gwanghaegun. Glass noodles came in the 20th century: Korea's first large dangmyeon factory opened in Sariwon in 1919, and recipes with noodles appear from the 1930s.

  1. 1

    Make the sauce and season the beef

    In a small bowl, mix 3 tbsp soy sauce, 2 tbsp sugar, the garlic and ¼ tsp black pepper. This one sauce seasons the whole dish. Put the beef and mushrooms in another bowl with 1 tbsp of it and 1 tsp sesame oil, work it in with your fingers and let them sit while you prep the rest. Cut the carrot into thin matchsticks, slice the onion thinly, cut the scallions into 2-inch lengths and wash the spinach well.

    Seong-jae's turning point in episode 9: he stops slicing the wild pine mushrooms with a knife and tears them along the grain, because torn by hand they keep their aroma. If you use oyster mushrooms, tear them by hand the same way.

    Make the sauce and season the beef
  2. 2

    Blanch the spinach, then boil the noodles in the same water

    Fill a large pot with water and bring it to a rolling boil. Dip the spinach in for 30 seconds, scoop it out with a strainer and cool it under cold water, leaving the pot on the heat. Drop the noodles into the same water and boil until soft and springy with no hard core, 7–8 minutes (check the package). Drain, rinse briefly under cold water, drain well and snip through the pile 2 or 3 times with kitchen scissors. Toss the noodles with 2 tsp sesame oil in a bowl to keep the strands separate. Squeeze the spinach dry, chop it once or twice, season it with 1 tsp sesame oil and a pinch of salt and put it in a large mixing bowl.

    Blanch the spinach, then boil the noodles in the same water
  3. 3

    Stir-fry the vegetables, palest first

    If you're making the egg garnish, do it first: beat the yolk and the white separately with a pinch of salt, then cook each as a thin sheet over low heat in a nonstick skillet brushed with a little oil, about 1 minute a side, without letting it brown. Roll up and cut into thin strips. Turn the same skillet to medium-high, add 1 tsp oil and stir-fry the onion and scallions with a pinch of salt until the onion just turns translucent, about 2 minutes; tip them into the large bowl. Add a little more oil and stir-fry the carrot with a pinch of salt for about 1 minute so it stays crisp (½ red bell pepper in thin strips can go in with it), then add it to the bowl.

    Working from the palest ingredients to the darkest lets one skillet handle every batch without washing. If anything sticks, a quick wipe with a paper towel is enough.

    Stir-fry the vegetables, palest first
  4. 4

    Cook the beef and mushrooms, then glaze the noodles

    Add 1 tsp oil and stir-fry the beef and mushrooms with their marinade over medium-high heat until the beef is just cooked through, 2–3 minutes; add them to the large bowl. Turn the heat down to medium, pour all the remaining sauce into the skillet and add the noodles. Stir-fry for about 2 minutes, until the noodles have soaked up the sauce and look glossy and evenly brown, then add them to the bowl.

    Cook the beef and mushrooms, then glaze the noodles
  5. 5

    Toss and serve

    Add the last 2 tsp sesame oil and the sesame seeds to the bowl and toss everything together, with tongs while the noodles are hot and with gloved hands once they cool a little. Taste, and add a splash of soy sauce or a pinch of sugar if needed. Pile it on a platter and scatter the egg strips on top. Japchae is good warm or at room temperature.

    Spoon it over a bowl of rice and it becomes japchae-bap, a standard on Korean-Chinese restaurant menus.

    Toss and serve

Episode 9 · The five-star japchae in the officers' mess

In episode 9, battalion commander Baek Chun-ik (Jung Woong-in) calls army cook Kang Seong-jae (Park Ji-hoon) to the officers' mess, where he has to satisfy regimental commander Bae Won-yeong (Ahn Gil-kang), whose palate rates five stars. Seong-jae's usual japchae only reaches four. When he asks for advice, the officers' mess cook Lee Ho-young (Oh Seung-baek) says he would keep cooking until he served something that makes the diner pick up his spoon again, and Seong-jae makes his japchae over and over. Then he finds wild pine mushrooms (songi) in the fridge and, told that they keep their aroma only when torn by hand, tears them along the grain instead of slicing them. The wild pine mushroom japchae is his first five-star dish. The commander, who had stopped expecting much once dessert was served, is won over by the mushrooms' aroma and shouts "Guilty!", guilty of being too delicious, as tvN's own clip of the scene puts it.

Cookware you’ll need

조리 도구

Any wide nonstick skillet works for the stir-frying (the spinach and noodles boil in a separate large pot). This is the 5-quart sauté pan we link to.

Calphalon Hard-Anodized Nonstick 5-Qt Sauté Pan with Lid
Wide enough to stir-fry each batch in a single layer, deep enough to toss the noodles with the sauce at the end, and nonstick, so the sticky glass noodles don't cling.
