It is interesting how different cultures have similar dishes and sometimes similar names. The Korean Japchae is similar to a Chinese dish known as Chap Chai in Fujianese (Hokkien) or Chai Choy in Cantonese. When translated, chap chai means mixed vegetables. Both japchae and chap chai has a mixed of vegetables and clear noodles in them. Though japchae is often cooked with strips of beef, it can be left out to keep it vegetarian.

I cook japchae often as it is a relatively quick and easy dish to prepare. One essential ingredient in japchae is dangmyeon or sweet potato noodles. This is a slightly thicker and darker noodle than the bean threads but has a similar slippery texture. This noodle is available in most Asian grocery stores. The one shown below is made in Korea but I also use the ones made in China which comes in a bag with green labels.

Let’s get to the recipe!

Prep time
Cook time
Total time
Serves: 6 servings
  • 4 oz (115g) sweet potato noodles (dangmyeon)
  • 3 tbsp soy sauce
  • 3 tbsp sesame oil
  • 2 tsp sugar
  • 2 cloves garlic, minced
  • 1 onion, thinly sliced lengthwise
  • 1 small carrot, peeled and julienned
  • 1 small red bell pepper, julienned
  • 8 oz (225g) spinach, ends trimmed and thoroughly washed
  • ΒΌ tsp pepper
  • 3 stalks green onions, cut into 2-inch lengths
  • 1 tbsp toasted sesame seeds
  1. Bring a medium pot of water to boil. Add sweet potato noodles. Boil for 5 to 6 minutes. Drain and toss with 1 tablespoon soy sauce and 1 tablespoon sesame oil and set aside.
  2. In a small bowl, mix remaining 2 tablespoons soy sauce and 2 teaspoon sugar. Set aside.
  3. In a large pan, heat remaining 2 tablespoon sesame oil. Add garlic and onions and fry until just softened, about 1 to 2 minutes. Add carrots and bell pepper and stir fry for another two minutes. Add spinach, cooked noodles, pepper, and soy sauce mixture. Cook for another 2 to 3 minutes.
  4. Add green onions and sesame seed. Stir to mix well. Remove and serve immediately.

Japchae is delicious with a bowl of steamed white rice and some Napa Cabbage Kimchi, Stuffed Oi Kimchi, or Kkakdugi.

    This looks so delicious! You have this effect on me – I always want to run out and immediately make your recipes! I’m particularly excited because I’m pretty sure I’ve seen these noodles in the supermarkets (in Israel it’s surprisingly easy to find Asian specialty ingredients). This is going on the list to make soon!

    • Biren says

      It is a surprise to hear that Asian ingredients can be easily found in Israel. I hope you will give this a try. It is quick, easy, and delicious! :)

    Biren, I love so may Koren dishes but Japchae is my all time favorite! Yummy! Your photos are remarkable as usual, doing perfect justice to this colorful and delicious dish! I’ll definitely be making your recipe this week for family dinner!! xo

  3. says

    oh yum this is one of my favorite things to eat, be in the chinese or korean version. but i like the fact that you sprinkled sesame seeds, it really makes it more polished and pretty πŸ˜€

    Congrats on the feature Biren! This looks fabulous. I love the look of those noodles. I’m thinking it’s time to take a trip back to my Asian grocery store and pick up a few goodies.

  5. says

    I haven’t tried using sweet potato noodles. I’ll definitely be looking for it the next time I go to the Asian Store, so I can try your Japchae which looks so appetizing!

    Congratulations on being featured in The Daily Meal, Biren! Well deserved!

    I just cooked Japchae last week for our usual mini gathering fun with my cousin & her family and all of them love it! It’s all gone when I decided to have some! lol
    That was the 2nd time I cooked Japchae and I always fried with bulgogi sauce. Maybe I should try your recipe some day. πŸ˜‰

  7. says

    Ha! I immediately thought it was Chap Chai when I saw the title and the picture before i read on. Japchae or Chap Chai – both are yummy.

    PS: Wow..your mooncake is really creative! There are so many versions available now, but it’s my first time seeing a butter squash flavour. Great one Biren!

    • Biren says

      This is a much simpler version than chap chai and can be cooked on a daily basis. I seldom make chap chai but it is a must have during the Chinese New Year. I do the entire she-bang then. :)

      Thanks Reese! Most people use purple sweet potatoes for this mooncake but since I could not get those sweet potatoes and did not want to use the orange ones, I decided to try butternut squash. I am glad I did as it turned out really well.

  8. says

    This is one of my favorite side dish whenever we’re in cook-your-own Korean BBQ places. Only yours have move hearty delicious veggies — yumm!

    Have a great weekend, Biren!

      This is something I discovered after moving here and having Korean friends. I cook it often now as it is tasty yet simple enough to do during the busy weeknights.

    Such a learning experience in gastronomy, every time I visit your blog, Biren. Love this delicious dish, and the noodles. Good thing we have an amazing Asian market in our area that carries everything, including all the spices, and fresh produce…not to mention all the different kinds of noodles you can get! Will check it out.
    Thanks for sharing:DDD

  10. says

    I have a big bag of these sweet potato noodles and I need to get them out and make this lovely dish. We usually go on Saturdays to get some already made at our Korean market…we can resist when we walk in it smells so good! Love your photos!

    Will be making this dish this friday with the bag of sweet potato noodles in my pantry. I am certainly looking forward to trying the taste and texture of this noodle. Congratulations on the mooncake feature – I wish you live over here so that I could badger you to make this for me!!!!! For nostalgic purpose, I would love a slice of mooncake with a cup of chinese tea on the festival day but I would not pay for a ridiculously-priced store-bought version! Making the mooncake is out of the question for me but I have book-marked this for future when I feel terribly BRAVE…..Keep up the great work!

    • Biren says

      Yes, you have to try this dish. I posted this with you in mind. πŸ˜‰

      I did not make any this time but may still do so a little later when butternut squashes are in season. It is a fun thing to make and it gives me a chance to use up some of that pandan paste sitting in the pantry.

  12. says

    Congrats on your feature!!! I looooove Japchae! It”s always a must order dish for me and my kids. It would be nice to make it at home but I never succeed. My family likes it but it’s just a tiny bit missing or something is wrong… I have to try your recipe! I really love your new gallery. I need to work on mine too, but I’m just so lazy…. :-(

  15. DongXing says

    Made this last Friday and served with a side of grilled salmon and mushrooms in teriyaki sauce. Simply simply delicious, the noodles absorbed the seasoning really well and we enjoyed it very much. I think the toasted sesame seed was definitely a great topping. Thank you for this recipe. We will definitely make this again.

  16. says

    I never knew about those noodles. I go to this Asian warehouse grocery store. The owners are Korean but they sell Japanese, Chinese, Vietnamese. I am quite sure I have looked at this product a million times and never realized that it was made from sweet potatoes. I totally am going to try this dish. Thank you.
