Korean Jajangmyeon (자짱면)

Jajangmyun 2

Jajangmyeon (or Jajangmyun) originated from the Chinese (Beijing) version of Zhajiangmian (炸酱面), which means ‘noodles with fried sauce’. The key difference between the two versions is the type of bean paste used to cook the sauce: the Chinese uses fermented brown soybean paste which is mainly salty; the Koreans use fermented black soybean paste which includes caramel and is hence not as salty. The secondary difference would be the ingredients added into the sauce: the former has their sauce stir-fried with minced meat; the Koreans fry theirs with loads of vegetables.

So… what made us want to cook this dish? The guy and I are now at episode 99 of Running Man, and we can’t count how many times it’s been since we’ve watched the hosts eat jajangmyeon. The way they slurp up the black greasy noodles bathed in thick sauce is just too irresistible for us. We badly needed to know how this Korean dish tastes like and why the Koreans love them so much.

  • The Korean sesame oil does indeed exude a different type of fragrance than the Chinese one, giving the dish a more authentic Korean taste.
  • Serve with additional side dishes like pickled radishes and kimchi to eat this just like the Koreans do!
  • As recommended by Maangchi, from which this recipe is adapted, this sauce also tastes great served with rice instead of noodles. Try it!
