Japchae Ingredients

Japchae Sauce, Meat and Veggies

  • Sauce: Usual things like soy sauce, garlic, sugar, oils. Sweet rice wine (mirin) is an optional choice.

How to make Japchae (the Easy Way)

Stir-fry Vegetables

  • Right at the end, add spinach and cook it until it’s soft. Then, take everything out of the pan and put it on a big plate to cool down.

Cooking the Meat

  • Heat the pan up again on high heat and add the beef (or pork). Cook until it’s done. You’ll notice juice from the meat.
  • Move the meat to the plate with the veggies, but leave the juice in the pan.

After cooking beef, keep the tasty juice in the pan. Mix it with the japchae sauce. It makes the noodles extra flavorful and yummy.

Seasoning the Noodles

  • Put the drained noodles in the pan with the meat juices. Pour the seasoning sauce over them.
  • Cook over medium heat until the noodles are very soft and most of the sauce is soaked up, which should take about 3-4 minutes.

Toss all together

  • Turn the heat down low. Put the veggies and meat back in the pan on top of the noodles.
  • Add some sesame oil and seeds. Mix everything well. Add more sesame oil if you like. Check the taste and add more seasoning if you want.

Storage and Reheating Tips

Store leftover japchae in the refrigerator. It will stay fresh for 3 to 4 days and reheats well in the microwave. For a fresher taste and texture, you can also stir-fry it with a little oil in a pan. The noodles will become soft and chewy again once reheated.

To cook Japchae
