How to Make Korean Japchae Noodles

  1. Soak. Cook the glass noodles according to package directions (usually boil 6 to 7 minutes). Drain, rinse under cold water, and cut with scissors into shorter lengths. Toss with 1 tablespoon of sesame oil.
  2. Stir-fry. Heat vegetable oil in a large skillet or wok over high heat. Cook the beef for 2 minutes until browned. Add garlic, carrots, mushrooms, and bell pepper. Stir-fry for 3 minutes until tender-crisp.
  3. Combine. Add spinach and green onions, cooking for 30 seconds until the spinach wilts. Add the noodles, soy sauce, remaining sesame oil, and sugar. Toss everything together over medium heat for 2 minutes until the sauce is absorbed.
  4. Serve. Transfer to a platter and sprinkle with sesame seeds. Serve warm or at room temperature.

Tips for the Best Korean Japchae Noodles

  • Cut the cooked noodles with kitchen scissors so they are easier to eat and toss with the vegetables.
  • Cook each vegetable separately if you want restaurant-quality results. Home-style all-in-one-pan is faster and still great.
  • Sweet potato glass noodles are in the Asian aisle of most grocery stores or at any Korean market.
  • Japchae is one of those dishes that tastes just as good at room temperature as it does warm.
  • Don’t skip the sesame oil on the noodles right after draining. It prevents clumping.

Fun Variations to Try

  • Make it vegetarian by skipping the beef and adding extra mushrooms and tofu.
  • Add thin egg strips (cook a beaten egg in a thin layer, slice into strips) on top.
  • Use chicken or shrimp instead of beef.
  • Add kimchi for a spicier, tangier version.
  • Serve over steamed rice for a more filling meal.
