What is japchae?
Japchae (잡채), pronounced like "chob-cheh," is a Korean sweet potato glass noodle dish stir-fried with vegetables, eggs, and optionally meat. It's a popular Korean noodle dish that's often served during New Years and special occasions, but also as an everyday meals or as a side dish.
What to eat with japchae
Japchae on it's own makes a great meal, but it's even better served with other dishes! Here are a few of our favorites:
- Gochujang BBQ chicken thighs
- Traditional napa cabbage kimchi or geotjeori (fresh kimchi)
- Mandu (Korean dumplings)
- Kimchijeon (Savory Kimchi Pancakes)
- Gyeran mari (Korean rolled omelette)
Ingredient notes

For the japchae:
- Sweet potato glass noodles - Also known as dangmyeon. These sweet potato noodles super bouncy, chew, yet tender.
- Beef or pork - Either proteins are great for making japchae. For beef, we usually use cuts like sirloin, flank, or skirt. As for pork, we love using pork chops, loin, and pork butt. Feel free to use whatever you have. You can even use chicken or omit the protein to make it vegetarian!
- Eggs - For making egg crepes. Eggs also make japchae extra fragrant and tasty!
- Onion, carrot, spinach, mushrooms, green onion - These are the most popular vegetables used in japchae. They add both color and texture to the noodles. So feel free to use all of them, use more of one, or omit certain ones. We do recommend using at least some onions.
- Salt and pepper - For seasoning the proteins and veggies. It is important that everything is seasoned so that the final product is well seasoned.
- Toasted sesame seeds (optional for garnish)
For the japchae sauce:
- Soy sauce - We recommend light sodium soy sauce, but regular soy sauce works too. If using regular soy sauce, use a tablespoon less per recipe. The soy sauce is not only one of the main flavorings of this noodle dish, it also gives noodles its golden brown color.
- Honey and brown sugar - A combination of honey and brown sugar makes the japchae more flavorful, but regular granulated white sugar is fine too.
- Sesame oil - This is a Korean pantry staple and adds a nice toasted, nuttiness to the dish. We highly recommend using some toasted sesame oil for japchae, but if you prefer, you can omit it.
Make it vegan or vegetarian
Japchae is easily customizable to your to your diet preference, whether vegan or vegetarian.
To make it vegetarian, the beef or pork can be omitted or replaced with tofu. If you are using tofu, make a little extra japchae sauce. Cut the tofu into strips, sear them, and let the tofu simmer in the extra japchae sauce until thick. This will give the tofu lots of flavor. Or simply just sear the tofu and add it to the japchae with the other ingredients.
For a vegan version, omit the beef or pork and eggs. The honey in the japchae sauce can be replaced with more brown sugar or white sugar. Extra vegetables can also be added to help bulk up the japchae.

1. Prepare japchae sauce. Combine the ingredients for the japchae sauce. Mix well and set aside until needed.

3. Prepare the egg. Add a small amount of oil to a large nonstick pan over medium heat. When the pan is hot, add the beaten egg. Tilt the pan to spread the egg into a thin layer.
Cook until the bottom of the eggs are set, then flip to cook the other side briefly. Remove from the pan to cool. Once cooked, fold it in half and cut into ¼ inch strips.
4. Sear the beef or pork. Add a small amount of oil into the same pan over medium high heat. Add the beef or pork and season with a pinch of salt and a few cracks of black pepper. Sear the meat on each side until cooked. Remove and set aside.

Recipe tips
- Don't over cook the noodles! It is very important to not overcook the sweet potato noodles to prevent so that the noodles are bouncy, not mushy.
- Rinse the noodles in cold water. After draining, make sure to thoroughly rinse the noodles in cold water until they're completely cooled. This is to remove excess starch and to keep the noodles bouncy and chewy.
- Drain the noodles well. Before adding the rinsed sweet potato noodles into the japchae sauce, make sure the noodles are very well drained so that the sauce doesn't become diluted.
- Cut the noodles after cooking for easier eating. We highly recommend cutting the sweet potato noodles into shorter strands using a pair of kitchen shears so that it's easier to eat.
Storage
Japchae makes for great leftover meals. To store, let the japchae cool completely before storing in an airtight container, in the fridge, for up to 2 to 3 days. Note that after a couple of days, the noodles will start to lose its bouncy texture.
Reheating
Japchae can be easily reheated in the microwave or on the stovetop. If you'd like, you could enjoy the noodles chilled as well.
Microwave method: Place the japchae into a microwave-safe container and cover loosely. Microwave until warm or hot, giving the noodles a mix midway through for even heat distribution.
Stovetop method: Add the leftover into a pan over medium heat, along with a small amount of water. Gently mix the noodles until warm and the water evaporates.
FAQ
What does japchae taste like?
A good japchae should have bouncy, slightly chewy noodles and is well balanced between sweet and savory with a hint of toasted sesame oil. The vegetables should have texture but not raw.
Is japchae served hot or cold?
Japchae can be served hot, cold, or at room temperature. However, we recommend enjoying the noodles while they are are hot or room temperature because the flavors are fuller and more well rounded.
How long does it take to cook japchae noodles?
Depending on the brand of japchae noodles, the cook time could vary. But typically japchae noodles take about 10 to 15 minutes to boil.
To check if the sweet potato noodles are done, pinch off a piece of noodle. If it breaks off easily, it's done. Also, you can check to see if the center of the noodles are clear or if they still look slightly white and starchy. White and starchy means the noodles need to be boiled a little longer.
