-
Whisk all the sauce ingredients together and set aside.
-
Boil the noodles for 6 to 7 minutes until springy and translucent, then drain, rinse briefly under cold water and cut roughly with scissors so they are manageable.
-
Toss the warm noodles with a third of the sauce immediately so they absorb it and do not stick.
-
Blanch the spinach for 45 seconds, refresh, squeeze dry and dress with a splash of sesame oil and a pinch of salt.
-
Stir-fry each remaining vegetable separately over high heat with a little oil and salt: onion 2 minutes, carrot 2 minutes, pepper 90 seconds, mushrooms 3 minutes.
-
If making the egg garnish, beat the eggs, cook them as a thin flat omelette, then roll and slice into fine ribbons.
-
Combine the noodles, all the vegetables and the remaining sauce in a large bowl and toss thoroughly with your hands, which distributes it far better than tongs.
-
Taste and adjust with more soy sauce or sesame oil, then serve warm or at room temperature topped with the egg ribbons and extra sesame seeds.
Chef’s Tips
- Dress the noodles while warm so they drink up the sauce rather than sitting in it.
- Toss with your hands. It is the only way to coat glass noodles evenly.
- Japchae is traditionally served at room temperature, which makes it excellent for taking places.
Common Substitutions & Variations
- Out of spring onions? A small regular onion, finely sliced, or a few chives stirred in at the end both cover the job.
- An eighth of a teaspoon of garlic powder per clove is the usual stand-in when you are out of fresh garlic — it will not caramelise the same way, but it carries the flavour.
Pairing Suggestions
- Soju or a cold lager
- Serve as part of a spread with bulgogi and kimchi
- Finish with fresh fruit
Storage & Reheating
Refrigerate 3 days. The noodles firm up when cold; refresh in a hot pan with a splash of water and sesame oil.
