Japchae — glossy sweet potato noodles with beef and vegetables, sesame-scented

Japchae was born at a seventeenth-century royal banquet, when a court official served noodles tossed with vegetables to a delighted king, and it has been a celebration dish ever since. Today the glassy sweet potato noodles, called dangmyeon, are stir-fried with beef and a tangle of colorful vegetables and finished with a generous hand of sesame. No Korean holiday table is complete without a big platter of it, and it is the banchan that gets seconds every single time.

Noodles with bounce, shimmer, and a whisper of sesame

The noodles are springy and glossy, each strand coated in a sweet-savory soy glaze, with crisp carrots, spinach, and mushrooms tucked throughout and a deep toasted-sesame finish. It is equally good warm, at room temperature, or cold from the fridge the next day, which makes it the perfect make-ahead dish for a crowd. Use sweet potato starch noodles if you can; their bouncy texture is the whole point, and nothing else chews quite like them. Pile it high and watch it disappear.

Step by stepInstructions

  1. Cook the noodles in boiling water for 6 to 7 minutes, until tender but still springy. Drain, rinse in cold water, and snip into shorter strands.
  2. Whisk the soy sauce, sugar, and half the sesame oil in a small bowl.
  3. Marinate the beef with 1 tbsp of the sauce and half the garlic for 10 minutes.
  4. Heat 1 tbsp vegetable oil in a wok or large skillet. Sear the beef until browned, about 2 minutes, and set aside.
  5. Stir-fry the onion, carrot, and mushrooms in the same pan with the remaining garlic for 3 minutes. Add the spinach and cook until just wilted.
  6. Return the beef to the pan, add the noodles, and pour in the remaining sauce. Toss over medium heat for 2 minutes.
  7. Off the heat, stir in the remaining sesame oil, the scallions, and sesame seeds. Serve warm or at room temperature.

💡 Chef tips & storage

Cook the noodles just until tender, then rinse in cold water and drain well so they do not clump. Toss everything with the sauce while the noodles are warm so they drink up the seasoning.
