Definitely not your ordinary glass noodle! What I find unique with Japchae and what I like most about it, is the translucent, slippery and elastic-like noodles made from sweet potato starch. It is definitely nothing like other noodles I've had before and I am loving it!
What is Japchae?
Japchae is a beloved Korean dish made of sweet potato starch noodle called Dangmyeon. It is stir-fried in sesame oil with vegetables, meat, and a sweet-savory sauce.
It is a commonly served side dish at holidays and special occasions but is also enjoyed as much on any ordinary day.
The process involved in preparing traditional Japchae means each of the ingredients will have to be stir fried separately then mixed together at the end which could be a lot of work. Stir-frying the ingredient separately is believed to give each ingredient an enhanced individual flavor and texture.
Japchae in a hurry
What they say about the traditional way is probably true. But of course, if you are as running out of time or simply in a hurry, you probably would like to cut through the long individual process.
It is really not much different. Only, you add each ingredient to the pan in order and with some intervals to allow them to slightly cook first and finish all together in the end.
And from the outcome of this dish, I could not really complain. It is almost if not exactly the same as the one I have at Korean restaurants. So it is either they are also doing some shortcuts or the difference between the methods are subtle that it can be ignored because it tastes so good anyway.
Ingredients for Japchae
The main ingredient is sweet potato starch noodles or dangmyeon.
Beef is commonly used as meat and should be marinated for at least a couple of minutes before cooking. A tender cut of beef like rib eye fillet is ideal.
For making the sauce and marinade, you will need soy sauce, sugar, sesame oil, garlic, ground pepper, and rice wine (mirin).
To add color and flavor, you will need some vegetables like carrots, bell pepper, shiitake mushroom, spinach, and green onions.
Lastly, you may add some toasted sesame seeds and strips of fried egg white and yolk to top it off.
Additional Tips for making Japchae
- You may consider serving Japchae with Bulgogi, because that would be practical. They use almost the same marinade so you can easily make two dishes in one prep.
- You can also use dried shiitake mushroom. Just soak them in water for a few hours beforehand. Oyster mushroom can also be used as an alternative.
- This recipe makes enough for 6-8 servings as a side dish. It can be eaten on its own and is good for 3-4 people then. For leftovers, store in the fridge in an airtight container for up to 3 days. It usually lasts longer than that but the texture and flavor may not be the same.
- You can have Japchae hot or cold. You can also easily warm it up in the microwave.
- If using the traditionally long noodles, cut them a little with kitchen scissors for easy mixing and eating.

- Heat vegetable oil in the pan over high heat. Squeeze out the marinade from the beef using your hands. Add the beef and stir-fry for a minute.
- Add the carrots and mushrooms and stir-fry for another minute. Add the onions and bell peppers and cook for another minute. Lastly, add the spinach, green onions and the remaining beef marinate (if any). Cook for 30 seconds and then add the cooked noodles. Toss with the rest of the ingredients for 2-3 minutes until noodles are fully cooked.

Hi! I want to try your recipe but do you have any recommendations if I can't find any type of mushroom?
You can use the dried or canned ones, but you can just skip them too.
Are the kcal that you include for the whole serving or is it per serving. If it says 6 servings and 689 kcal, is 689 every 1 serving? Thanks 🙂
It is per 1 serving but the serving is big.
Super love this recipe! Just did it today and it was a hit. Actually tastes like the japchae we ordered in one Korean restaurant we went to. Can't wait to try your other recipes Chef Bebs. Thanks!
Hi Jen, I am happy that you like my easy version of Japchae. Thanks for the 5 stars...
