About this dish
Japchae is a signature Korean dish of glass noodles stir-fried with beef, spinach, carrots, onions, and shiitake mushrooms in soy sauce and sesame oil.

The noodles are made from sweet potato starch and turn translucent as they cook, absorbing the seasoning to become glossy and springy rather than starchy or heavy. The defining technique is cooking each component separately before combining them at the end. Spinach softens quickly and needs only a brief wilt; carrots are stir-fried to keep a slight bite; shiitake mushrooms are cooked until pleasantly chewy; and beef is marinated in soy sauce, sesame oil, sugar, garlic, and pepper before being stir-fried so it stays tender without any gamey edge. Tossing the noodles in soy sauce and sesame oil right after boiling prevents them from clumping together. When everything is brought together at the end, each ingredient keeps its individual texture while the seasoning unifies the dish. Japchae appears at virtually every Korean celebration including Chuseok, Lunar New Year, birthdays, and wedding feasts, and a large batch keeps its quality well into the following day.
Ingredients
Instructions
Read the steps as a cooking flow: prep, heat, seasoning, doneness control, and finish.
- 1Season
Soak 200 g sweet potato noodles in lukewarm water for 30 minutes.
Slice the carrot and onion thinly, rinse the spinach, and drain it well so excess water does not dilute the seasoning later.
- 2Season
Season 150 g beef for 10 minutes with a small portion of the soy sauce, sugar, and sesame oil.
Toss only until the surface looks lightly coated, not wet, so the beef browns instead of steaming.
- 3Heat
Boil the soaked noodles for 6-7 minutes until they turn translucent and springy.
Rinse under cold water, drain thoroughly, and cut once with scissors if the strands are too long to toss evenly.
- 4Control
Heat a pan over medium heat and stir-fry the onion, carrot, spinach, and beef separately.
Remove each ingredient as soon as its color brightens or the beef just cooks through to prevent watery japchae.
- 5Control
Put the noodles in a large pan with the remaining 3 tablespoons soy sauce, 1.5 tablespoons sugar, and 2 tablespoons sesame oil.
Toss over medium heat for about 2 minutes until glossy and evenly seasoned.
- 6Season
Add all the stir-fried ingredients and toss gently for 1-2 minutes, just until combined.
Check the seasoning, then let the japchae rest for 5 minutes so the noodles absorb the flavor before serving.
