If you’re a Korean food lover, japchae needs no introduction. With chewy glass noodles, thin silvers of colorful vegetables, julienned omelet, mushrooms, and meat all on one plate, this famous Korean noodle dish might just be the perfect food.

This japchae recipe is the result of my YouTube collaboration with my good friend Seonkyoung Longest, who is a Korean-born celebrity chef. We’ll show you all the tips and tricks on how to make the best japchae at home.

What is Japchae?

Japchae (잡채 – or chapchae) is a classic Korean stir-fried noodle dish seasoned with a sweet and savory sauce. The name japchae describes a mix of finely cut ingredients—vegetables, egg, mushroom, and meat—that are included in the noodles.

According to Seonkyoung, Korean cuisine shares the same philosophy as Japanese cuisine where the balancing of colors and seasonality are taken into consideration. The juxtaposition of flavors and textures and the vibrant colors are all part of the appeal of a recipe like japchae.

As one of Korea’s most-loved dishes, not only can you find japchae being served at small parties, fancy banquets, and special occasions like New Year’s day, but it is also a staple dish enjoyed any day of the week.

In Korea, people enjoy japchae hot, warm, or even at room temperature, because it is delicious regardless of how you serve it.

Korean Glass Noodles

What Are Korean Sweet Potato Glass Noodles (Dangmyeon)?

Korean sweet potato glass noodles called dangmyeon (당면) are made from the starch of sweet potatoes. They do not contain wheat so they are gluten-free.

The noodles are stiff and grayish looking and often sold dried in a big bag. Once cooked, they become translucent and tender. They also come in long strands, so you’ll need to cut them in half or thirds after cooking.

You can buy Korean sweet potato glass noodles in Korean or most Asian grocery stores. Amazon and other online Asian grocers also carry them too.

How to Make Japchae

You’ll need to do some prep work to get all the ingredients ready, but apart from that, japchae is a relatively easy dish to put together. The noodles store well in the refrigerator for a day or two and reheat easily, so you can definitely make it in advance.

Ingredients You’ll Need

  • Korean sweet potato glass noodles (dangmyeon)These springy glass noodles are an integral component of japchae. Please do not substitute it with other types of glass noodles. It will change the character of the dish. The good news is you can easily find sweet potato noodles in Korean or Asian grocery stores or online.
  • Vegetables: We used onion, carrots, bell peppers, and spinach in the recipe.
  • Shiitake mushrooms: If you cannot find shiitake mushrooms, sub with other meaty types of mushrooms.
  • Eggs: You make a thin omelet and cut it into thin strips. You can leave it out for a vegan japchae.
  • Protein: We used thinly sliced beef, but you can leave it out or swap it with seafood, tofu, or use more shiitake mushrooms.
  • Roasted sesame oil: It adds an unmistakably wonderful and nutty aroma to the dish. Use generously.
  • Japchae sauce: Korean soy sauce*, sugar, sesame oil, sesame seeds, garlic, and black pepper.

*Korean soy sauce is best, but you can sub it with Japanese soy sauce.

Overview: Cooking Steps

  1. Cut all the ingredients into julienne strips. It’s important to thinly slice all the ingredients into a uniform shape so they mix well with the long noodles. That way when you eat, the veggies, eggs, and meat will cling to the noodles and have more balanced flavors.
  2. Stir fry, blanch, and cook each ingredient separately. Each ingredient has a different texture and it requires a different cooking time, so we need to cook them separately. Stir-frying everything all at once in the frying pan will only result in uneven textures as some vegetables will wilt before the others are cooked. Cooking separately also helps keep the colors of each ingredient nice and bright!
  3. Mix all together! After everything is prepared and cooked, place the ingredients in a large platter or bowl, then pour the sauce over the noodles first and let them absorb the flavors. Once the noodles are well coated, get ready to mix! We’ll do the traditional Korean way by putting on plastic gloves and tossing the noodles with everything else together.

What Dishes to Serve with Japchae

I love that you can enjoy japchae in any way you like. It certainly makes a fulfilling standalone meal itself. For a party, you can serve it on a large platter directly as the main dish on the table, or as a smaller side (banchan) along with other dishes.

Here are some of our favorite recipes that go well with japchae:

Instructions
 

  • Gather all the ingredients.
    Japchae ingredients

To Marinate the Beef

  • In a medium bowl, combine the seasonings for the beef: 1 Tbsp Korean soy sauce, 1 Tbsp sugar, ½ Tbsp toasted sesame oil, ½ Tbsp mirin, and 1 clove garlic (chopped). Whisk it all together. Cut ½ lb beef into thin strips 3 inches (7.6 cm) long. Add the beef to the bowl with the sauce and toss to coat evenly. Set aside to marinate for at least 10 minutes.
    Japchae 1

To Cut the Vegetables

  • Thinly slice ½ onion and 5 shiitake mushrooms.
    Japchae 2
  • Cut ½ carrot and ¼ red bell pepper into thin julienne strips.
    Japchae 3

To Cook the Toppings

  • Now, make the omelette. (If doubling the recipe, make 2 omelettes with 2 eggs each.) Heat a large frying pan on medium heat. When the pan is hot, add 1–2 tsp toasted sesame oil and distribute it evenly in the pan (use less for a nonstick pan, more for a regular pan). Next, beat and add 2 large eggs to the pan and swirl them around to cover the pan‘s surface in a thin layer. Cook until it’s just set, about 2 minutes. Then flip the egg over and cook for another 2 minutes. Transfer the omelette to a plate to let cool.
    Japchae 4
  • Next, we‘ll cook the vegetables. Make sure to cook each different vegetable separately, starting with the light-colored ones and ending with the dark-colored ones, so that they will retain their beautiful colors. In the same pan that you just used (without washing), heat 1–3 tsp toasted sesame oil over medium heat. Add the sliced onions and a pinch of salt and sauté until tender. Remove the onions from the pan to a platter large enough to eventually hold all the cooked ingredients.
    Japchae 5
  • In the same pan, repeat this process with the shiitake mushrooms next, followed by the carrot strips, and ending with the bell pepper strips. As you finish cooking each ingredient, place in a separate pile on the platter.
    Japchae 6
  • Now, cook the beef. Using the same pan over medium heat, heat 1–3 tsp toasted sesame oil and add the marinated beef and sauté until cooked through and all the moisture has evaporated. Transfer from the pan to the large platter with the cooked vegetables.
    Japchae 7
  • When the omelette is cooled, roll it up and cut it into thin ribbons. Set aside on a separate plate.
    Japchae 8
  • Bring a large pot of water to a boil. In the meantime, prepare a large bowl of iced water. Once the water is boiling, add 1 tsp Diamond Crystal kosher salt and 12 oz fresh spinach. Cook for about 10–15 seconds (American spinach is more tender than Japanese spinach). Use tongs or chopsticks to transfer the spinach from the pot to the iced water to stop the cooking. (You‘ll cook the noodles next in this boiling water, so do not discard it.) Gather the spinach and squeeze out as much water as you can. Add the spinach to the platter with the other cooked ingredients.
    Japchae 9

To Cook the Noodles

  • Add 14 oz Korean sweet potato glass noodles (dangmyeon) to the same boiling water that you used to blanch the spinach. Boil the noodles according to the package directions, about 6 to 10 minutes. Drain well, transfer to a bowl, and toss with some toasted sesame oil to coat so the noodles don‘t stick to each other. Cut the long noodles with kitchen shears so it‘s easier to eat and they‘ll mix easily with the sauce and toppings. Then, add the noodles to the platter in a pile next to the rest of the cooked ingredients.
    Japchae 10

To Assemble the Japchae

  • In a small bowl, combine all the ingredients for the sauce: ⅓ cup Korean soy sauce, ⅓ cup sugar, 2 Tbsp toasted sesame oil, 1 Tbsp toasted white sesame seeds, 1 clove garlic (chopped), and freshly ground black pepper. Whisk well. Pour the sauce only on top of the noodles.
    Japchae 11
  • Combine the sauce and noodles first so that the noodles can absorb the sauce (I used my gloved hand). Once the noodles are well coated, add in the stir-fried vegetables and beef and mix everything together.
    Japchae 12
  • Finally, add half of the omelette ribbons and some sesame seeds and toss together. Transfer to a serving platter and garnish the Japchae with the rest of the omelette ribbons and more toasted white sesame seeds, as desired. Serve warm or at room temperature. Enjoy!
    Japchae 13

To Store

  • You can keep the leftovers in an airtight container for up to 2 days. When you are ready to serve, reheat it in a frying pan with 1–3 tsp of oil and 1–2 Tbsp of water until the noodles become translucent again.

Wow… watching you and Seonkyoung make Japchae really inspires me! I’m going to make this for my daughter’s 19th birthday this weekend. She’s gonna love it because she’s been missing home-made Asian food much rather than College dorm food. Thanks, ladies! You both are so cute!5 stars

Hi Hanna! Thank you so much for reading Nami’s post!
We hope you and your daughter enjoy this delicious Japchae as much as we do.
Happy Cooking!

YUM. I made this last night and my husband and I loved it. I’m eating cold leftovers now and it’s still fabulous. I bought the sweet potato glass noodles a while ago. I made a yakisoba-like dish with them and didn’t like them. But this is the dish they were made for!! I substituted green cabbage for the spinach and added spicy peppers instead of sweet. Oh, the spicy with the sweet sauce! Yum. I also ran out of sesame oil, and had to sub canola for the rest. Can you imagine how much better this would have been had I had more sesame oil?! Next time. And there will be a next time because this was fabulous. Domo arigato!!5 stars

Hi Allison! Thank you! We are so happy to hear you enjoyed the recipe.
Thank you for sharing your cooking experience with us. Happy Cooking!🤗

Yesss, I cooked Japchae this morning, so delicious 😋 thank you so much for the recipe ♥️

Hi Wenu! Aww!😊 It looks very good!
Thank you for trying Nami’s recipe and sharing your cooking experience with us.
Happy Cooking!

Hi Nami-San, it was a yummy dish. But how should I keep this dish if I had lots left? I ate one round then left it out to cool for a later snack and found it became somewhat lumpy and sticky. Popped it in the microwave to heat it up and the potato starch noodle became stickier. Grateful for your advice, thanks!5 stars

Hi Mie! Thank you very much for trying Nami’s recipe and for your kind feedback!
To reheat this dish, we recommend using the microwave. Usually, the noodle will loosen up after it gets warmed up. But if you skip Step 12 (Drain well and pour some sesame oil to coat noodles so they won’t stick.) or wasn’t enough sesame oil, the noodle will be stickier. So would you please add a little more sesame oil to the noodle next time?
We hope this helps!

I tried out the recipe, but had to make some substitutes based on what I had on hand. I used rice vinegar with sugar instead of mirin, and I did not have seasame seeds so I used (don’t kill me) everything bagel seasoning (which has both black and white sesame seeds as well as poppy seeds, but I didn’t notice it too much). I did not add beef to the Japchae as I like it vegetarian. Instead I made seared salmon separately to eat with the dish, and paired both with a pickled radish and cucumber salad. It came out quite well for a first time try! One question – the overall flavour was mild, is this because I did not use mirin? Any suggestions for how to increase the flavour, especially if I am trying to go easy on the salt intake?5 stars

Hi Michelle! Thank you very much for trying this recipe from our website and sharing your cooking experience with us.
The main reason for the mild flavor could be from missing the beef flavor. Replacing the beef with some Shiitake mushroom might be a better idea to balance the flavor of this dish. Also, Mirin does not contain a vinegar taste. Using rice wine and sugar would be closer taste to Mirin. Please check out this attached link about Mirin and how to substitute. https://www.justonecookbook.com/mirin/
We hope this is helpful. 🙂

I didn’t expect it’ll so good! My family loved it, thank you!5 stars

Hi Alicja! Yay! We are so happy to hear you enjoyed Japchae!
Thank you for trying this recipe and for your kind feedback!

Awesome recipes thank you for sharing can’t wait to make these will let you know how they turned out5 stars

Hi June,
Thank you! We hope you enjoy this dish.☺️

Hi Nami,
I’ve done a couple of your recipes and I was always satisfied with the outcome however I did not bother to comment (from laziness). This time however I wanted to let you know that I absolutely loved how it turned out! I am a student in a quite expensive country so I don’t eat in restaurants but I really craved for noodles and this recipe was exactly what I wanted. Most of them I took for lunch to university and they tasted perfectly when cold. The only ingredient I had to substitute were mushrooms. I also wanted to compromise on the noodles but after seeing the comments I made the effort to find the Korean sweet potato glass noodles – and I don’t regret that decision. Wonderful recipe that I will surely repeat!5 stars

This has a well-written instructions to follow for non-Koreans who love Korean dishes. I made this last night with another Korean blog recipe, but turned out so bland. She skipped the marinade for beef and spinach that you mentioned here. Also, you have a better plan. You blanched the spinach first before boiling the sweet potato noodles that way we maximized the use of the pot of water and utilized the nutrients of that left behind spinach juice. Also, thanks that you mentioned to drizzle sesame oil on the noodles to prevent it from sticking to each other. Thank you for this recipe. I should have found it before I made it last night. Thought your blog is just Japanese dishes. The more reason to read more till the I get to your oldest post😉 Love from our household!!!

Wayyyyy too sweet! Was like a candied noodle.
Had to throw our huge bowl. What a waste of time, effort and ingredients.
Too bad, because most other recipes on this site are excellent.2 stars

Hi Nami,
I tried the recipe again, this time with 1/2 the sugar (1/6 cup) in the sauce. It was delicious! Thank you for your feedback. I have made this twice since! Arigato!4 stars

Tried making Japchae once with Vermicelli and oh believe me the taste is not so good even though I follow all of your steps and ingredients. Not as chewy as korean sweet potato noodles! Regardless, thank you for the wonderful recipe!

Hope you can help me. I had a honorable Korean family 40 years ago when I came to this country. That was my first contact with Korean food. I just loved it!!!! I learned how to make Japchae with them , but I remember she used this pink thing they called a fish. It add a special taste to the dish. I used to go to Jersey City, NJ and buy it. The years went by and we lost touch with the family and I never made the dish again. Living on the internet lately I found so many recipes for this delicious dish and I made it few times lately, but no one mentions the dry pink ingredient. Do you know what I am talking about it?

Thank you. Nami for getting back to me. Love your recipes !!!! I already tried the internet in search of my honorable family. If one day you find out about this ingredient, please, let me know.5 stars
