Japchae (잡채) is a delicious Korean noodle dish made with chewy glass noodles called dangmyeon (당면). These noodles, made from sweet potato starch, are mixed with colorful vegetables and juicy beef, giving the dish its unique texture and flavor.

Often called Korean glass noodle stir-fry, Japchae is seasoned with soy sauce and sesame oil, giving it a rich, savory taste. While it’s a popular side dish, Japchae is also enjoyed as a main course, especially during special occasions like Lunar New Year, Korean Thanksgiving (Chuseok), or family gatherings.

There are many types of Korean japchae recipes, but beef japchae with colorful vegetables is the most popular and well-known. I’ve found an easy way to make it, even in large batches, without the stress.

The chewy, transparent glass noodles paired with tender yet crisp colorful vegetables and savory beef create a comforting Korean flavor that’s perfect for gatherings. You can also omit the beef for a vegetarian option. Now, you can easily share this delicious dish with everyone, anytime!

Make Japchae the Easy Way with This Simple Recipe

Traditional Japchae can take time because each ingredient is usually cooked separately. But this easy recipe simplifies the steps, so you get the same authentic homemade taste with much less effort.

Instead of boiling the noodles separately, you can just soak them in hot water for a few minutes to soften them up. Then, you can stir-fry them directly with the sauce, which gives the noodles that perfect chewy texture—all in one pan, making cleanup easier.

For the vegetables, this recipe lets you stir-fry onions, carrots, and peppers together first, then add mushrooms and spinach at the end. This speeds up cooking while still keeping the veggies colorful and fresh.

Notes on Key Ingredients

Noodles

Sweet potato starch noodles (dangmyeon) for making japchae.

No Japchae is complete without dangmyeon (당면) in the Korean kitchen. These Korean glass noodles, made from sweet potato starch, are clear and chewy. They are essential in dishes like Andong jjimdak (Korean Braised Chicken) and Galbitang (beef short rib soup).

Where to buy japchae noodles (dangmyeon):

Dangmyeon can be easily obtained from Korean or Asian markets. Online stores is another option. They are often labeled as Korean potato vermicelli or Korean cellophane noodles. Make sure they are authentic Korean dangmyeon.

Japchae Sauce, Meat and Veggies

  • Sauce: Usual things like soy sauce, garlic, sugar, oils. Sweet rice wine (mirin) is an optional choice.
  • Meat: Beef or pork add a depth of flavor. Thin, tender cuts of beef such as sirloin or striploin are the most popular choices. You can quickly marinate the beef with basic marinade ingredients to capture the full Korean flavor.
    • To make vegetarian japchae: simply omit the beef. The dish remains delicious even without it.
  • Veggies: Onion, carrot, pepper, spinach, and shiitake mushrooms are essential.

How to make Japchae (the Easy way)

How to prepare japchae Noodles

Soak dangmyeon noodles in hot water for 15-minutes and remove. This step makes them soft and ready to cook while you are stir-frying veggies. The noodles will cook fast with sauce later on.

Prepare beef and sauce

Quick Meat Marinade: Mix thinly sliced beef in a marinade and set aside.

Japchae Sauce: Mix all the sauce ingredients and set aside.

Stir-fry Vegetables

Here’s an easy way to stir-fry veggies to shorten the cooking time:

  • Start by cooking the veggies that take longer, like onions, carrots, and peppers. Then, toss in greens and mushrooms. This way, you cook faster and all the veggies taste great.
  • At the end, add spinach and cook briefly until soft. Transfer everything on a big plate and let them cool down.

Brown the beef

Cook the beef on high heat until done. Remove the beef and place it on top of the vegetables. Keep the meat juice remaining in the pan; it has all the delicious flavor, so don’t throw it away!

Cook japchae noodles

Add the drained noodles in the pan with the meat juices. Pour the sauce over and cook until the noodles are very soft and most of the sauce is soaked up.

Mix all together

Return the veggies and meat back in the pan and mix with noodles. Taste and add more seasoning if needed.

Helpful Recipe Tips

  1. Cool down the veggies and beef slightly: After cooking, let the veggies and beef cool down a bit to keep their soft yet crisp texture. I spread them out on a large platter to speed up the cooling process before mixing them with the noodles later on.
  2. Don’t toss the meat juice: The juice left in the pan after cooking the beef is full of flavor—don’t waste it! Toss the soaked noodles in it before adding the Japchae sauce for an extra boost of taste.
  3. Use cut sweet potato noodles (dangmyeon): Most dangmyeon comes in large bundles, which can be tricky to mix with the other ingredients if not cut. Precut dangmyeon makes things easier, but if you can’t find it, just cut the noodles with kitchen scissors (but not too short).
  4. Finish with sesame oil, sesame seeds, and black pepper: For extra flavor, drizzle more sesame oil and sprinkle sesame seeds and black pepper to taste. I love adding plenty of toasted sesame seeds and pepper, but feel free to adjust to your liking!

Storage and Reheating

Store leftover Japchae in the refrigerator, where it will stay fresh for 3 to 4 days. The best way to reheat it is by giving it a quick stir-fry with a little oil. This brings the noodles back to life and makes the dish taste as fresh as if it were just made.

For meat marinade

For japchae sauce

Instructions 

For the glass noodles

  • Soak the glass noodles in hot water for 15 minutes, then drain and set aside. Pre-soaking will soften the noodles and make them easier to cook.

For the meat seasoning

  • Slice beef (or pork) into thin match sticks (about 1/4-inch thick) against grain and season with soy sauce, sugar, and sweet rice wine; set aside.

For the Japchae sauce

  • In a mixing bowl, combine all the japchae sauce ingredients, and set aside.

To cook Japchae

  • Heat 1 tablespoon oil in a large skillet or wok over medium high heat. Add onion, carrot, pepper, and a pinch of salt; stir-fry until soft but have a slight crunch to complement the soft noodles. Add sliced shiitake mushrooms and another pinch of salt. Continue to stir-fry until soft. Add more oil if needed.
  • Add spinach at the end and stir-fry until spinach is wilted. Remove the skillet from the heat and transfer the vegetables to a large plate to cool.
  • Reheat the pan over high heat with the remaining 1 tablespoon oil, add the beef (or pork) and stir-fry until fully cooked. You will see the juice coming out from the meat. Transfer the meat to the large plate with the reserved vegetables, reserving the juice in the pan.
  • Add the drained glass noodles to the pan with the meat juices. Pour the japchae sauce over the noodles and toss to combine. Let the noodles cook over medium heat until they are soft and the sauce liquid is mostly absorbed into the noodles, about 3-4 minutes.
  • Reduce the heat to low. Add the vegetables and meat back to the pan over the noodles. Add sesame oil and sesame seeds and toss all together to incorporate. Drizzle more sesame oil if you wish. Taste and season more according to your taste.

Notes

To make this Japchae vegan or vegetarian: omit the beef (or pork) and the meat seasoning step in the recipe.
Leftover beef bulgogi meat is a great substitute for fresh beef in this recipe. You don’t need to season the beef separately if using the leftover marinated bulgogi.
