What is japchae?

Japchae (잡채) literally means “mixed vegetables.” However, the main ingredient of this classic dish is Korean sweet potato starch noodles (dangmyeon, 당면), also known as glass noodles. Japchae is an essential dish for traditional holidays and special occasions.

There are many variations using different ingredients, such as Spicy Seafood Japchae and Kongnamul Japchae.

For traditional japchae, the chewy and springy noodles are nicely paired with thin strips of beef (or pork) and various vegetables in a slightly sweet and savory sauce. It’s also common to add an egg garnish (jidan, 지단). Sometimes, I also sprinkle with some finely chopped pine nuts.

To make vegan japchae, simply omit the meat and add a little more mushrooms or other vegetables. Pan-fried tofu is also an excellent substitute for the meat.

Serve it as an appetizer or a side dish or over a bed of rice to make it a main dish.

How to make japchae


Sweet potato starch noodles (dangmyeon, 당면) are a staple in Korean homes. I always have a couple of bags in my pantry. They are not only used for this iconic dish, but also great in soups and stews.

There are various ways to prepare japchae noodles. Some people presoak the noodles before cooking them. Some don’t rinse the noodles after cooking. Even the package instructions vary, depending on brands. I don’t find it necessary to soak the noodles. The noodles cook up pretty fast without being soaked. I boil for about 8 minutes until the noodles are soft and elastic. These noodles should NOT be “al dente!”

I then rinse the noodles in cold water, drain well, marinate with the prepared sauce, and then pan-fry to give them a soft yet bouncy texture.

Meat and vegetables:

I usually use lean, tender beef but pork loin is also very common in japchae. The classic vegetable additions are carrots, spinach, mushrooms, onions and scallions. Other common vegetable options are chili peppers, bell peppers, garlic chives, cucumbers, etc.

Shiitake (pyogo beoseot, 표고버섯) and wood ear mushrooms (mogi beoseot, 목이버섯) are most typical in this dish, but oyster mushrooms (neutari beoseot, 느타리버섯) are also commonly used.

The japchae ingredients are separately cooked and combined at the end into a deliciously colorful dish. This traditional method is what makes this dish so special! Once you have the meat and vegetables prepared, it really doesn’t take much time to cook.

Here, I’ve streamlined the process a little and cook some ingredients together, where appropriate. Regardless, do not overcook the vegetables. The vegetables should be slightly crunchy or “al dente” to pair well with soft noodles.


The real secret to successfully creating the authentic flavor of this dish is to find the right balance between soy sauce and sugar. This japchae recipe will give you that right balance! Be sure to proportionately increase the sauce amount if you’re using more ingredients than the amounts called for in the recipe.

To make the process a little easier, I make a bowl of sauce first to be used throughout the cooking process. Use brown sugar, if available, for color and a bit extra flavor.

How to store leftovers

Leftover japchae should be kept refrigerated. It will keep well for 3 to 4 days and reheat nicely in the microwave. The noodles will get soft and chewy again when reheated.

  • Add 1/2 tablespoon of oil to the pan, and stir fry the carrot over medium high heat, sprinkling with a pinch of salt. When the carrot sticks are half way cooked, about a minute, push them to one side of the pan to make room for the onion slices. Stir-fry the onion slices until translucent, sprinkling with a pinch of salt. Stir-in the scallion and cook briefly. Do not overcook. The vegetables should be crisp. Transfer to the bowl with the noodles.

Optional egg garnish

  • Separate the egg white and yolk. Lightly beat the white by gently cutting it with a spoon. Stir the yolk with a spoon until smooth. Heat a lightly oiled nonstick skillet over medium low heat. Pour each egg part into a thin layer, by tilting the skillet and/or spreading with a spoon. Cook each side briefly. (Do not brown the egg.) Roll it and thinly slice.

  1. Shiitake and wood ear mushrooms are typical for japchae. Dried shiitake has a concentrated flavor and meatier texture. You can use any kind of fresh/dried mushrooms such as oyster mushrooms or button mushrooms.
  2. In this updated recipe, you'll use the same pan for cooking the noodles and spinach and for stir-frying the noodles and other ingredients.
  3. Leftover japchae should be kept refrigerated. Japchae reheats well in the microwave. The noodles will get soft and chewy again.
