Japchae is a classic Korean stir-fry dish made with sweet potato glass noodles, tender beef strips, and a colorful mix of vegetables like mushrooms, spinach, and bell peppers, all tossed in a savory-sweet soy-based sauce.

Ingredients

  • 200g sweet potato glass noodles
  • 200g beef sirloin, thinly sliced
  • 1 tbsp soy sauce (for marinating beef)
  • 1 tsp sesame oil (for marinating beef)
  • 1 tsp sugar (for marinating beef)
  • 2 tbsp vegetable oil, divided
  • 1 small onion, thinly sliced
  • 1 red bell pepper, thinly sliced
  • 1 yellow bell pepper, thinly sliced
  • 150g spinach
  • 100g shiitake or button mushrooms, sliced
  • 2 cloves garlic, minced
  • 3 tbsp soy sauce (for sauce)
  • 2 tbsp sugar (for sauce)
  • 2 tsp sesame oil (for sauce)
  • 1 tbsp toasted sesame seeds
  • Salt and pepper to taste

Instructions

  1. Cook sweet potato noodles according to package instructions. Drain, rinse under cold water, and cut into shorter lengths with kitchen scissors.
  2. Marinate beef with 1 tbsp soy sauce, 1 tsp sesame oil, and 1 tsp sugar for at least 10 minutes.
  3. Heat 1 tbsp vegetable oil in a large pan or wok over medium-high heat. Stir-fry beef until just cooked through, then remove and set aside.
  4. In the same pan, add remaining oil and sauté onions until soft. Add bell peppers, mushrooms, and garlic, and stir-fry until tender-crisp.
  5. Blanch spinach in boiling water for 30 seconds, drain, and squeeze out excess water. Set aside.
  6. In a large mixing bowl, combine noodles, beef, vegetables, and spinach. Add 3 tbsp soy sauce, 2 tbsp sugar, 2 tsp sesame oil, and mix well until evenly coated.
  7. Season with salt and pepper to taste, sprinkle with toasted sesame seeds, and serve warm or at room temperature.

Notes

  • Sweet potato glass noodles give Japchae its signature chewy texture.
  • Can be served warm or cold, making it great for parties.
  • Adjust sugar and soy sauce amounts to taste for a sweeter or saltier flavor.
  • For vegetarian Japchae, omit beef and increase mushroom quantity.
