  • 7 oz dry Korean Glass Noodles (당면 Dangmyeon) – doesn’t have to be exact
  • 8 dried Shitake mushrooms (3/4 cup fresh shitake mushrooms, sliced)
  • 1 cup carrots , julienned
  • 1 small onion , thinly sliced
  • 6 green onions – cut 4 green onions into 2 inch (5 cm) lengths and chop 2 green onions
  • 1 cup fresh wood ear mushrooms (Mogi Beoseot 목이버섯) or 10g dried wood ear mushrooms
  • 2 Tbs vegetable oil

Marinade for Shitake mushrooms

  • 2 tsp soy sauce (jin ganjang 진간장) See my Know your Soy Sauce post for more info
  • 1 tsp rice wine
  • 1 tsp garlic , chopped
  • 1 tsp sugar
  • ½ tsp sesame oil
  • dash of black pepper

Sauce for Japchae

  • 3 Tbs dark soy sauce (jin ganjang 진간장)
  • 1 Tbs + 1tsp sugar
  • 1 Tbs rice wine or mirin
  • 1 Tbs sesame oil
  • 1 Tbs sesame seeds
  • 2 Tbs Shitake mushroom water from hydrating mushrooms (substitute plain water if using fresh mushrooms)


  • Soak Korean glass noodles (Dangmyeon or Vermicelli) and any dried mushrooms in room temp water for 2- 3 hours. You can also soak both mushrooms and glass noodles overnight.
  • Clean and cut other vegetables: julienne carrots, onions and cut green onions into similar lengths as carrots and onions. Split lengthwise in half if the white part of green onion is thicker than a pencil.
  • When mushrooms are fully reconstituted, rinse and clean the mushrooms. When cleaning wood ear mushrooms, make sure the bottom part are free of dirt and white matter by rubbing all of it off with your fingers.
  • Drain and squeeze any excess water from shitake mushrooms. DO NOT DISCARD all of the mushroom water. Save 2 Tbs of mushroom water for later. Do not squeeze the mushrooms too much, just one gentle squeeze with your hands is good enough. Just enough so that mushrooms are not dripping water.
  • Cut shitake mushrooms into thin slices. Cut wood ear mushrooms into bite size pieces (size of quarters).
  • Marinate Shitake mushroom slices with soy sauce, rice wine, garlic, sugar, sesame oil and black pepper.
  • Make sauce for Japchae by mixing everything in a bowl except water. Set aside.
  • Drain glass noodles and set aside.
  • Heat 2 Tbs of vegetable oil on medium high heat in a wok or deep stir-fry pan and stir-fry chopped green onions (about 2 Tbs) for 30 seconds or until cooked but not browned.
  • Add marinated Shitake mushrooms to pan and stir-fry for 30 seconds or so.
  • Add carrots, onions and wood ear mushrooms and stir-fry for about 2 minutes. Season lightly with salt (1/8 tsp) and pepper (1/8 tsp). Vegetables should not be fully cooked.
  • Add glass noodles (dangmyeon) to pan. Stir-fry noodles and vegetables together to coat the noodles with oil for about 1 minute. Some noodles will start to become more transparent and thicker after 1 minute.
  • Add 2 Tbs Shitake mushroom water and stir-fry until noodles are fully cooked (transparent) but still al dente. Probably about 30 seconds to 1 minute.
  • Add Japchae sauce to pan and stir-fry for another 2 minutes or so until the sauce is fully absorbed. Quickly taste noodles along with vegetables. Adjust seasoning to taste.
  • When noodles and vegetables are all cooked, turn off heat.
  • Immediately, add green onions to pan and toss. Green onions will get perfectly cooked in the residual heat.
  • Sprinkle sesame seeds and another drizzle of sesame oil before serving.


Leftovers should be stored in fridge and will last for couple days. In summer Korean Glass Noodles can spoil pretty quickly so be careful about leaving it at warm room temp or in inside a hot car.
Reheat leftover Japchae in pan on low heat for couple minutes while stirring often until all noodles become soft.
