Ingredients

  • 8 oz dried sweet potato glass noodles
  • 8 oz beef sirloin or rib-eye, thinly sliced
  • 1/3 cup soy sauce
  • 2 tbsp granulated sugar
  • 2 tbsp sesame oil
  • 4 garlic cloves, minced
  • 2 tbsp vegetable oil
  • 4 cups fresh baby spinach
  • 1 medium carrot, julienned
  • 1 red bell pepper, thinly sliced
  • 4 oz shiitake mushrooms, stems removed, sliced
  • 4 green onions, chopped
  • 2 tsp sesame seeds, toasted
  • 1/4 tsp black pepper

Instructions

  1. 1

    Cook 8 oz dried sweet potato glass noodles according to package directions (usually 6-8 minutes in boiling water). Drain, rinse with cold water, and use scissors to cut into 6-inch lengths. Toss with 1 tbsp soy sauce and 1 tsp sesame oil.

  2. 2

    Mix the sauce: combine remaining 1/3 cup soy sauce, 2 tbsp granulated sugar, 2 tbsp sesame oil, 4 minced garlic cloves, and 1/4 tsp black pepper in a bowl. Divide roughly in half - one half for the beef marinade, one half for the noodles.

  3. 3

    Toss 8 oz thinly sliced beef sirloin or rib-eye with half the sauce and marinate for 10 minutes.

  4. 4

    Heat a large skillet or wok over medium-high heat. Add a little 2 tbsp vegetable oil and cook the marinated beef for 2-3 minutes until browned and the internal temperature reaches 145°F. Set aside.

  5. 5

    In the same pan, stir-fry 1 julienned medium carrot and 1 thinly sliced red bell pepper for 2 minutes. Add 4 oz stems removed, sliced shiitake mushrooms and cook 2 minutes more. Add 4 cups fresh baby spinach and 4 chopped green onions and cook just until wilted, about 1 minute.

  6. 6

    Add the noodles and the remaining sauce to the pan along with the cooked beef. Toss everything together over medium heat for 1-2 minutes until heated through and evenly coated.

  7. 7

    Transfer to a platter, sprinkle with 2 tsp toasted sesame seeds, and serve warm or at room temperature.

Questions

What is Japchae?

A beloved Korean stir-fried noodle dish made with chewy glass noodles, colorful vegetables, and thin-sliced beef, all tossed in a sesame-soy sauce. Served warm or at room temperature, it's a staple at celebrations and weeknight tables alike. This reference files it under Korean dinner: made on the stovetop, rated medium and about 50 minutes start to finish.

What internal temperature should Japchae reach?

For Japchae, the target internal temperature is 145 F (about 65 C), given in step 4. A probe thermometer removes the guesswork.

How long should Japchae marinate?

Step 3 reads: "Toss 8 oz thinly sliced beef sirloin or rib-eye with half the sauce and marinate for 10 minutes." Follow the time in step 3. Shorter still seasons the surface. Much longer is not better with acidic marinades, which turn the outside of meat or fish mushy.

Is there a substitute for toasted sesame oil in Japchae?

The entry for Japchae calls for 2 tbsp sesame oil. In its place: There is no neutral substitute for the toasted flavor. Warm a spoonful of sesame seeds in a neutral oil, or leave it out and finish with toasted seeds.

Can I make Japchae gluten-free?

Yes. The gluten in Japchae is 1/3 cup soy sauce. Swap the soy-based sauce for tamari or coconut aminos. Everything else proceeds as written.

How do I store and reheat Japchae?

Refrigerate what is left of Japchae within two hours and eat it within three days. Reheat gently on the stovetop. The pasta keeps drinking the sauce as it sits; loosen it with a splash of water or stock.
