Japchae is Korea's celebration noodle dish — present at every birthday, holiday, and family gathering. These silky, translucent sweet potato glass noodles are stir-fried with a rainbow of julienned vegetables and tender strips of marinated beef, all tossed in a sweet soy-sesame sauce.
The key to great japchae is cooking each ingredient separately to preserve its individual color and texture, then tossing everything together at the end. It sounds like extra work, but the result — a dish where each component shines while contributing to a harmonious whole — is worth it.
Japchae is equally delicious served hot, warm, or at room temperature, making it the perfect potluck and party dish.
Ingredients
- 200g sweet potato glass noodles (dangmyeon)
- 150g beef sirloin, sliced thin
- 2 cups fresh spinach
- 1 carrot, julienned
- 1 red bell pepper, julienned
- 1 onion, thinly sliced
- 5 dried shiitake mushrooms, soaked and sliced
- 3 tbsp soy sauce
- 2 tbsp sugar
- 2 tbsp sesame oil
- 2 cloves garlic, minced
- 1 tbsp vegetable oil
- Sesame seeds for garnish
- Salt and pepper
Instructions
- 1
Marinate beef with 1 tbsp soy sauce, 1 tsp sugar, 1 tsp sesame oil, and garlic. Set aside for 15 minutes.
- 2
Cook glass noodles according to package directions (usually 6-7 minutes in boiling water). Drain, rinse with cold water, and cut into manageable lengths. Toss with 1 tbsp sesame oil.
- 3
Blanch spinach for 30 seconds, squeeze out all water, and season with a pinch of salt and 1/2 tsp sesame oil.
- 4
Stir-fry each vegetable separately in a hot skillet with a bit of oil: carrots for 2 minutes, bell pepper for 1 minute, onion for 2 minutes, mushrooms for 2 minutes. Season each lightly with salt. Set aside.
- 5
In the same skillet, cook marinated beef over high heat for 2-3 minutes until just done.
- 6
Combine noodles, all vegetables, beef, remaining soy sauce, sugar, and sesame oil in a large bowl. Toss gently but thoroughly.
- 7
Garnish with sesame seeds. Serve hot, warm, or at room temperature.

Tips & Storage
Pro Tips
Cooking each vegetable separately is the traditional method and produces the best result. It preserves each vegetable's color and texture.
Cut noodles after cooking so they are easier to toss and eat.
Japchae tastes great at room temperature, making it ideal for parties and potlucks.
Do not over-season individual vegetables — the final toss with soy sauce and sesame oil brings everything together.
Storage
Refrigerate in an airtight container for up to 3 days. Japchae is one of the rare noodle dishes that keeps well.
Reheating
Reheat gently in a skillet with a splash of sesame oil, or microwave. It is also delicious served at room temperature — just toss and re-season if needed.
