What is Japchae?
Japchae (잡채) (aka chap chae) is a very popular stir-fried Korean glass noodle dish that is typically a side dish (banchan) but it can also be eaten as a main dish as well and served with a bed of rice.
Similar to the chewy texture of tteokbokki, japchae is made of a combination of springy, chewy, and incredibly flavorful glass noodles with a variety of colorful vegetables cooked in a sweet and savory sauce.
This is a vegetarian chap chae recipe and does not contain any meat in it, but you can easily add some chicken, beef, or pork to this recipe easily by pre-frying some and mixing it in at the very end.
Whenever I bring this japchae dish to any potlucks, parties, or BBQs they are always a hit, so if you're looking for something to bring to a BBQ gathering, you should definitely consider this dish. It's easy to make ahead and reheat in the microwave the next day.
Why You Will Love This Korean Glass Noodle Recipe
- I streamlined the process of this chap chae recipe so that you will not have to boil the noodles in water. The result makes perfectly springy and chewy noodles so that you don't need to worry about overcooking them.
- Since the noodles will not be fully cooked from the soak, the sauce (which has extra water) will fully cook the noodles all the way through while you are stir-frying. This will let the noodles absorb even more sauce into it which will give them even more flavor.
- The sweet and savory japchae sauce is delicious and gets fully absorbed right into the noodles since the noodles are not boiled.
- It's quick and easy and can be made all in one large pot or frying pan.
Ingredients for Japchae
- Egg - Plain omelet cut into thin ribbons, or if you're pressed for time, quickly scramble the egg and set it aside to add at the end when you are mixing the noodles
- Peppers - I like to use yellow, orange, or red bell peppers for their sweeter flavor.
- Shiitake Mushrooms - I like to cook these ahead of time in a sweet soy sauce, and then cut them into thin slices
- Meat - This is not a traditional ingredient, but I have added in leftover meats in the past for a heartier noodle dish. If you choose to keep it vegetarian, you can just skip adding the meat.
- Garlic - Adds a bit of extra flavor, but I like to keep this optional because it can overpower the dish.
- Vegetables - I like to stick to the basic vegetables which are carrots, onions, green onions, spinach, and peppers
- Soy Sauce, Sugar, and Toasted Sesame Oil - This trio is what makes the delicious sweet and savory japchae sauce.
- Sesame seeds - For more flavor, garnish this Korean noodle dish with lots of toasted sesame seeds
What are Clear Korean Glass Noodles?
The noodles used in Japchae are called Korean glass noodles (dangmyeon 당면). They are a type of Korean vermicelli made with sweet potato starch. These sweet potato starch noodles are thicker than your typical Asian glass noodles and are about 2 mm thick in diameter.
When sweet potato noodles are cooked, they turn into clear and shiny noodles with a springy and chewy texture when they are not overcooked.
They do not contain any wheat so they are a good option for any type of gluten-free diet and they are very delicious because they are fantastic at soaking up sauces which makes them incredibly flavorful.
How to Get Springy (Not Mushy) Korean Glass Noodles
- On almost every noodle packaging instruction that I found, they always teach you to boil the noodles first. Don't do it! 🙂 Seriously.
- What I found worked amazingly was just soaking the noodles for 20 mins in warm to hot water. I just used hot tap water for simplicity but make sure to run the tap until the water is hot. No need to boil the noodles in a pot or rinse them afterward.
- I found boiling the noodles in a pot, agitated the starches too much and it kept the water at a constant boiling point which would usually overcook the noodles on the outside but still had raw centers - the result would be mushy noodles. Soaking in hot water softens the noodles evenly through
- Soaking the noodles in a large mixing bowl created soft and pliable noodles but they will still be slightly raw. When I cook the noodles directly in a large pot with the vegetables, I mix in a bit of water to the japchae sauce to cook the noodles all the way through with the sauce - this will absorb more of the sauce directly into the noodles and will make it much more flavorful.
How to Make Japchae
- Preparation is important for this dish, so you will have to pre-cut all the vegetables ahead of time. You can use this time to also soak the noodles in warm to hot tap water while you are preparing the vegetables and making the japchae sauce.
- There are a lot of ingredients in this dish, so make sure you use a large frying pan for this.
- First, I cooked all the vegetables together for about 3-5 mins until they were soft and then I transferred them out of the pan to another bowl and set it aside for later.
- Once the noodles were soft, I would drain the water out of the boil and cut them into 4-inch length pieces. I cooked the noodles, with half the soy sauce mixture and when the noodles were almost cooked (they will look shiny and translucent), I added the vegetables back into the frying pan and added the other half of the soy sauce mixture.
- ...and voila! 🙂 You're done! Time to enjoy your chewy Korean Glass Noodles (Japchae / ChapChae)!
How to Serve Korean Glass Noodles
- Eat them As-Is - They are absolutely delicious as is as a main dish! I like to serve them warm or at room temperature. I don't recommend serving them cold, since the noodles won't be as chewy and tend to be harder.
- As a Side Dish (Banchan) - They also go great as a side dish with Korean fried chicken, Korean Tofu Stew, Spicy Korean Pork Bulgogi, or mixed in with Tteokbokki.
- Mixed in with Rice - It seems a bit odd, but I love mixing it with my Tuna Mayo Rice Bowls, and Kimchi Fried Rice as well to give it a bit more texture and chewiness.
Storing and Reheating
Once you put these glass noodles in the fridge, the noodles will get hard from the cold so you can't serve them straight from the fridge.
To reheat japchae noodles, put them in the microwave for one minute at a time, (for up to a few minutes) while mixing them with a utensil in between minutes to prevent cold spots. Mixing and using small time intervals, will prevent the noodles from getting too hot too quickly which can melt its delicate texture springy texture.
You can store this in the fridge for up to a week.

Vegetables
- 1-2 carrots (cut into matchstick slivers, approximately 1 ½ cups)

Instructions
Preparing the Sweet Potato Glass Noodles and Vegetables
- In a large bowl, add warm to hot tap water and soak the noodles in it for 20 mins. Prepare the vegetables while you are waiting for the noodles to soak.
- Peel the carrot and cut them into thin matchstick sizes. Set aside.
- Slice the onions and peppers. Set aside
- Boil the spinach for 2 mins. Once it is done, run it under cold water to stop the cooking process and squeeze and squeeze all the water out. The texture should be dry and not soggy. Season it with salt and set it aside. Alternatively, you can also skip boiling the spinach and put it directly in with the rest of the vegetables to save some time.
- Toast sesame seeds in a frying pan on low heat until brown. Set aside.
- Finely chop the green onions and set them aside for the end.
- After 20 mins, when the noodles are soft and pliable, drain the water out and cut them roughly 4 inches in length. Set it aside for later.
Make the Japchae Sauce
- In a small bowl, dissolve ¼ cup sugar with ½ cup hot water. Then add in ½ cup soy sauce and 2 tablespoons sesame oil. Set it aside.
Cooking the Japchae
- In a large non-stick frying pan, add oil and set the heat to medium.
- Once the oil has warmed up, add in the veggies (except the green onions) and cook them for approximately 3-5 mins or until the vegetables are soft. Remove them from the pan into a dish and set it aside.
- Add the noodles to the pan and half the soy sauce mixture and cook for about 2-3 mins. Keep flipping the noodles, until they are transparent and glossy and no longer translucent.
- When the noodles are almost done, add the vegetables back in and add in the remainder of the soy sauce mixture and cook for another 1-2 mins.
- Turn off the heat and add in the green onions and sesame seeds and mix well. (It's might be easier to mix it with your hands)
- Enjoy!

This recipe looks fun to make! I have to find these noodles. I've seen similar Thai style flat noodles, but these look a little different. Love the cooking method.

Helen @ Fuss Free Flavours says
Such a great dish, with so many delicious ingredients. I love how foods from around the world are becoming so much easier to get. I too found the best way to prepare noodles, of any kind, is to soak in hot water from the kettle, rather than boiling in a pan. Always a much better result.
Joyce says
Yes!! I so agree! ^_^

J. Lee says
Another YUMMY !! This time, you came up to my another favourite Korean sweet potato noodles. Sometimes I like to eat food in a dry mix with others such as vegetables, bell peppers etc. that those ingredients you recommended to add in.
When this kind of noodles is better mix to eat without soup base, is very beneficial for kids or adults to bring to school or work for lunch. Sesame oil and fried sesame seeds bring up very distinct flavour. Honestly, the moment when I saw this colourful nice ready-to-eat noodles on the table, it seems like it stimulated my stomach to growling, and mouth watering too.
WELL RECOMMENDED, and thank you to bring up another easier cooking recipe.
Joyce says
