What you will need

This recipe uses 6 simple ingredients that you can find at any grocery store:

  • 200 g sweet potato glass noodles dangmyeon
  • 150 g beef sirloin thinly sliced
  • 1 whole carrot julienned
  • 100 g spinach blanched
  • 3 tbsp soy sauce
  • 1 tbsp sesame oil

Step by step instructions

Step 1: Cook the Noodles

Boil the sweet potato glass noodles in a large pot of water for about 6 to 8 minutes until tender but still slightly chewy. Drain, rinse with cold water, and cut into shorter lengths with scissors. Toss with 1 tablespoon of soy sauce and 1 teaspoon of sesame oil.

Step 2: Cook the Beef and Vegetables

Marinate the beef slices in 1 tablespoon soy sauce and a pinch of sugar for 5 minutes. Stir fry the beef in a hot oiled skillet for 3 minutes. In the same pan, stir fry the carrot julienne for 2 minutes. Season the blanched spinach with a little sesame oil and salt.

Step 3: Combine Everything

Add the cooked noodles to the skillet with all the cooked vegetables and beef. Pour the remaining soy sauce and sesame oil over everything. Toss well over medium heat for 2 to 3 minutes until everything is heated through and evenly coated.

Step 4: Finish and Serve

Taste and adjust seasoning with additional soy sauce or sesame oil as needed. Transfer to a large serving platter and garnish with toasted sesame seeds and additional sliced green onions. Serve warm or at room temperature.

Easy substitutions

Missing an ingredient? Here are some swaps that work perfectly:

  • beef sirloin → mushrooms such as shiitake for a vegetarian version
  • sweet potato glass noodles → regular vermicelli or mung bean noodles

Common mistakes to avoid

Watch out for these pitfalls that can affect your results:

  • Overcooking the glass noodles until they become too soft and lose their pleasant chewy texture
  • Not cutting the cooked noodles into shorter lengths which makes them difficult to toss and eat
