Ingredients for Japchae (Korean Royal Sweet-Potato Glass Noodles with Spinach, Mushrooms & Sesame) (4 Servings)

  • 1.25 lbs (or 2.5 cups) bouncy sweet-potato glass noodles (dangmyeon), prepped into bite-sized pieces
  • 1.5 cups wood-ear and shiitake mushrooms, washed and trimmed
  • 1 cup blanched spinach
  • 1 medium onion and 3 cloves garlic, finely minced with toasted sesame oil
  • 1.5 tbsp traditional South Korea seasoning (soy sauce, garlic, roasted sesame seeds)
  • 2.5 tbsp traditional cooking oil, sea salt, cracked black pepper, and fresh citrus or herbs

Step-by-Step Cooking Instructions

  1. Cook or soften the noodles/pasta in salted boiling water until just al dente, then drain while reserving 1/2 cup cooking water.
  2. Heat oil in a wide wok or deep skillet over high heat; flash-sauté garlic, toasted sesame oil, and soy sauce, garlic, roasted sesame seeds for 30 seconds.
  3. Add bouncy sweet-potato glass noodles (dangmyeon) and wood-ear and shiitake mushrooms, stir-frying briskly for 5–6 minutes until tender-crisp.
  4. Toss in the noodles along with a splash of reserved liquid so the South Korea sauce clings glossily to every strand.
  5. Finish with blanched spinach and serve piping hot.
