Japchae

Save this recipe on:

Japchae is Korea’s beloved stir-fried glass noodle dish, brimming with vibrant vegetables, silky sweet potato noodles, and the umami richness of soy sauce and sesame oil. Originally a royal court favorite, it’s now found on nearly every Korean celebration table, often served warm or at room temperature.

What makes Japchae so irresistible is its perfectly balanced taste. It offers a little bit of everything: savory, slightly sweet, nutty, and deeply satisfying without being heavy. The texture is just as important as the flavor: chewy noodles, crisp-tender vegetables, and seared beef (if you choose to add it).

Why You’ll Love This Japchae

Japchae is one of those dishes that seems like it takes hours, but it actually comes together quite easily. The ingredients are simple, the flavors are clean, and it’s endlessly customizable. You can make it vegetarian, vegan, or add beef, chicken, or even shrimp. It also keeps well, making it perfect for meal prep or potlucks.

And let’s be honest: the glossy, colorful noodles are beautiful. It’s a dish that turns heads and fills bellies.

What Kind of Noodles Should I Use for Japchae?

Japchae is made using Korean sweet potato noodles, known as dangmyeon. These translucent glass noodles are slightly chewy and absorb flavor incredibly well. They’re naturally gluten-free and can be found in most Asian grocery stores or online. Avoid substituting with rice noodles or pasta—it just won’t be Japchae without those springy sweet potato strands.

Ingredients for the Japchae

To make a truly great Japchae, you’ll want fresh, colorful vegetables and quality noodles. Here’s what you’ll need:

Sweet Potato Noodles
These are the base of the dish. Once boiled, they become translucent and slightly chewy, which gives Japchae its signature texture.

Carrots
Thinly sliced into matchsticks, they add color and sweetness.

Spinach
Quickly blanched, spinach brings a mild bitterness that balances the dish.

Onion
Sliced and sautéed until soft, onions add aroma and a gentle sweetness.

Shiitake Mushrooms
These add depth and a subtle umami richness.

Bell Pepper
Red or yellow bell peppers lend crunch and vibrant color.

Garlic
Minced garlic gives the Japchae that signature savory backbone.

Soy Sauce
The salty-sweet umami base that coats the noodles.

Sesame Oil
Adds that nutty fragrance essential to Japchae.

Sugar
Just a touch to balance the soy sauce and enhance the vegetables.

Beef or Tofu (Optional)
For protein, use thinly sliced ribeye or tofu if you’re keeping it plant-based.

Sesame Seeds
A sprinkle on top for texture and visual appeal.

How To Make the Japchae

Step 1: Cook the Noodles

Bring a large pot of water to a boil and cook the sweet potato noodles according to package instructions, usually 6-7 minutes. Rinse under cold water and toss with a little sesame oil to prevent sticking.

Step 2: Prepare the Vegetables

Blanch the spinach for 30 seconds, squeeze out excess water, and cut into bite-sized pieces. Sauté onions, carrots, mushrooms, and bell peppers separately in sesame oil until just tender. Lightly season each batch with a pinch of salt.

Step 3: Cook the Beef or Tofu

If using beef, sauté thinly sliced ribeye with garlic, a drizzle of soy sauce, and a touch of sugar. Cook until browned. If using tofu, pan-fry slices until golden on each side.

Step 4: Mix It All Together

In a large bowl, combine the noodles, all the cooked vegetables, and protein. Add soy sauce, sugar, sesame oil, and minced garlic. Toss everything together until well combined and glossy.

Step 5: Serve

Top with toasted sesame seeds and serve warm or at room temperature.

How to Serve and Store Japchae

Japchae is traditionally served either warm or at room temperature, making it incredibly versatile. It feeds around 4 to 6 people as a main dish or more as a side dish at gatherings. This dish also makes great leftovers. Store it in an airtight container in the fridge for up to 4 days. To reheat, a quick toss in a pan over medium heat with a splash of water will bring it right back to life.
