Ingredients

• 6 ounces 170 grams Korean potato starch noodles (dangmyeon, 당면)
• 1 small carrot
• 1 small sweet onion
• 2 scallions
• 4 ounces 110 grams lean beef (sirloin or rib eye)
• 4 - 5 dried shiitake mushrooms soaked until plump - see note
• 6 ounces 170 grams fresh spinach
• vegetable oil for stir frying
• salt and pepper

Sauce

• 3 tablespoons soy sauce
• 2 1/2 tablespoons sugar
• 2 tablespoons sesame oil
• 2 teaspoons minced garlic
• 2 teaspoons roasted sesame seeds
• Egg garnish jidan - optional

Instructions

• Combine all sauce ingredients in a small bowl and mix well until the sugar is dissolved.
  
• Cut the carrot into match sticks. Thinly slice the onion. Cut the scallions into similar lengths.
  
• Cut the beef into thin 2-inch long strips and mix with 1 tablespoon of the sauce. Cut the stems off the mushrooms, and slice into 1/4-inch thin strips. Season with 1 tablespoon of the sauce.
  
• Blanch the spinach in boiling water only until wilted. Drain quickly and shock in cold water. Squeeze out excess water, cut into about 2-inch lengths, and lightly season with salt and pepper.
  
• Bring a pot of water to a boil, and cook the noodles according to the package directions (usually 6 - 7 minutes). Rinse in cold water and drain. Cut the noodles with kitchen shears or a knife into 6 -7 inch lengths. Mix in 2 tablespoons of the prepared sauce in a large bowl.
  
• In a large non-stick skillet, stir fry the noodles over medium heat, stirring frequently, until translucent and a bit sticky (about 4 minutes). Transfer back to the bowl.
  
• Add 1/2 tablespoon of oil to the pan, and stir fry the onion until translucent over medium high heat, lightly sprinkling with salt and pepper. When the onion is almost done, stir-in the scallion and cook briefly. Transfer to the bowl with the noodles. Stir fry the carrot for 1 to 2 minutes until softened. (Do not overcook. The vegetables should be crisp.) Transfer to the bowl.
  
• Stir fry the beef and mushrooms together until the meat is cooked through, 2 - 3 minutes. Transfer to the bowl.
  
• Add the spinach and the remaining sauce to the bowl with all other prepared ingredients.
  
• Toss well by hand. Adjust the seasoning to taste by adding a little more (start with 1/2 teaspoon) soy sauce and/or sugar as necessary.
  

Notes

Dried shiitake is ideal for its concentrated flavor and meatier texture, but you can use any kind of fresh/dried mushrooms such as oyster or button mushrooms.
Leftover japchae should be kept refrigerated. Japchae reheats well in the microwave. The noodles will get soft and chewy again.
