Steps

  1. Prepare the ingredients

    Here is 300 g of beef for bulgogi.

    For the vegetables, I simply prepared bell peppers, onion, and shiitake mushrooms.

    One each of red and yellow bell pepper for color.

    Depending on what you have in the fridge or your personal taste, you can use fish cake, carrots, wood ear mushrooms, oyster mushrooms, water dropwort, spinach, and more for the japchae ingredients.

  2. Slice the ingredients

    Press the beef with paper towels to remove the blood, then cut it into bite-sized pieces.

    Cutting them not too small, about the same length as the noodles, makes them easy to pick up and eat.

    Thinly slice the onion, not too thin.

    Halve the bell peppers, trim the ends, scoop out the insides, and slice them into strips.

    Use the trimmed ends for stir-fries or salads.

    Remove the stems from the shiitake mushrooms. Since they are thick, slice them horizontally about twice and then cut into thin strips.

  3. Stir-fry the ingredients

    Heat oil in a pan, add the onion, and stir-fry.

    Stir-fry while keeping a bit of crisp texture so it doesn't get too mushy.

    Adding two or three pinches of salt each time you stir-fry an ingredient to lightly season it makes each ingredient taste much better in the finished dish.

    Stir-fry the bell peppers as well, adding a little salt.

    Add the beef to the pan, then add 2 tbsp regular soy sauce (jin-ganjang), 2 tbsp mirin (cooking rice wine)...

    Add 1/2 tbsp minced garlic, 1/2 tbsp sugar, and a little ground black pepper, then mix to season.

    Since the meat is thin, there is no need to marinate it; just stir-fry it right away.

    Stir-fry until the juices released while cooking have boiled down...

    Add the shiitake mushrooms, stir-fry briefly, and remove from the heat.

    Shiitake mushrooms wilt quickly just from the residual heat.

    Each time you finish stir-frying an ingredient, pour it into the mixing bowl or a large plate to cool the heat slightly, so they stay crisp rather than becoming mushy.

    Once cooled, I gave them a rough mix.

  4. Boil the noodles

    Add the sweet potato glass noodles (dangmyeon) to vigorously boiling water and cook.

    Boil 1 to 2 minutes less than the time indicated on the noodle package.

    Since they need to be stir-fried once more in the sauce, cooking them until slightly underdone gives you the perfect chewy yet tender japchae texture in the end.

    Rinse in cold water until all heat is completely gone, and drain thoroughly.

    Cut the noodles if they are too long, as they will be awkward to eat.

  5. Stir-fry the noodles

    Add the noodle seasoning to the pan: 5 tbsp regular soy sauce (jin-ganjang), 2 tbsp oyster sauce, and 2 tbsp sugar. At this time, also add 5 tbsp cooking oil so the noodles mix smoothly when stir-frying.

    Once the noodles are evenly colored, transparent, and springy, remove from the heat.

    Let the noodles cool slightly, then add them to the stir-fried ingredients and mix evenly.

  6. Season the japchae

    Adjust the overall seasoning of the japchae with about 2 tbsp regular soy sauce (jin-ganjang), and finish with 5 tbsp toasted sesame oil, 5 tbsp toasted sesame seeds, and a little ground black pepper.

    For japchae with meat, adding black pepper at the very end prevents greasiness and makes it much tastier.

  7. Complete the dish

    The japchae is done.

    Prepping and slicing the ingredients takes some effort, but the seasoning is simple and it is not particularly difficult.

    I had some beef for bulgogi, so I made beef japchae.

    Adding plenty of crisp, aromatic bell peppers gives it a great flavor that pairs wonderfully with the meat.

    The noodles are truly chewy, and the seasoning is spot on, making it really delicious.
