Korean Japchae Recipe (Glass Noodles with Ribeye)

This japchae recipe features sweet potato glass noodles that are chewy and soft, as well as tender and juicy ribeye meats. It’s also loaded with earthy vegetables, bell peppers, sweet carrots, and mushrooms.

What is japchae?

Japchae, a Korean type of noodle recipe, is made with special glass noodles. It is a popular side dish (or banchan) that can be enjoyed at both Korean restaurants and at your home. My favourite places to eat japchae is MoRanGak & Baekjeong.

It’s a simple dish that can be translated as “japchae” to mean “mixed vegetable” (in Korean). This dish is usually made with mushrooms, spinach, carrots, and sesame oils.

Ingredients in japchae


Glass Noodles for Korean Japchae Recipe

Clear noodles are my favorite part of japchae! They are made from sweet potato and turn translucent once they’re cooked. They are also known as “dangmyeon” in Korean. These noodles are made of sweet potato starch and are covered with cellophane.

Glass noodles can also be made with other ingredients, such as purple sweet potatoes or mung beans. Korean sweet potato noodles are described as chewy and bouncy. They aren’t flavored and can be seasoned with any seasoning that you like.

Look for the names of the noodles in the store to identify the right type.

  • sweet potato noodles
  • yam noodles
  • glass noodles
  • cellophane noodles
  • dangmyeon
  • clear noodles


Vegetables for Korean Japchae Recipe

There are many vegetables that you can substitute or add to japchae. Similar to yaki Udon, you can add any vegetables you like, but the main ingredients are usually carrots, onions and dried mushrooms (shiitake, wood ear), bell peppers. You can add cucumbers, chili peppers or other ingredients.

Meat / protein

Japchae can also be made with protein. My favorite is ribeye, which is tender, fatty and delicious. The best ribeye cap is my personal favorite. Costco doesn’t always have prime ribeye caps, so I was hesitant to buy it.

The price is around $20/lb, so it’s not inexpensive. However, you can always make great japchae with cheaper cuts. They can be used with skirt steak or other lean cuts, as they are sliced thinly.

You can make it vegan by skipping the protein and using only vegetables. It’s equally delicious.

Jidan is an optional topping made from egg yolks that have been lightly beaten and cooked in a pan. Then, the eggs are cut into thin strips. Similar to the egg strips that we add to Vietnamese Bò Bía and bun thang, this is also an option topping.

Japchae sauce

Japchae sauce can be described as a simple, easy seasoning made with soy sauce, sesame oils, black pepper and dark brown sugar. The soy sauce and sesame oils give it a balanced saltiness, while the sugar adds sweetness.

How to make japchae

Although japchae can be made quickly, noodle dishes that contain many ingredients and require different cooking times or processes can be confusing if you don’t have a clear timeline. You may need to prepare the ingredients separately before you mix them all together. This dish is similar in pancit canton and pancit Palabok.

  7. Sauté the mushrooms.
  8. Sauté the bell peppers and carrots.

Authentic Korean Japchae Recipe

Japchae can be served hot from the pan or chilled from the refrigerator. It’s best semi-chilled from a fridge, when I have my steamy Korean barbecue at home or at a restaurant. It gives me a nice balance. This is a great side dish to eat with Korean potato salad and kalbi. You can save any leftover noodles in an airtight container, and keep them in the refrigerator.

The noodles can be kept in the refrigerator for up to four days. You can heat japchae by placing it in a microwave-safe bowl. To prevent it from drying out, you can also place a damp towel on top. To heat it up, I prefer to cook for 30-second intervals.

  • Season the noodles with the sesame oil. To prevent them sticking, mix until the noodles are well coated.
  • You can cut the noodles into manageable pieces with a pair scissors. They can be cut into 6 inch strips. You can also cut them however long you like. Because they are long, this will make it easier to handle the noodles and make them easier to eat.

Cook the green onions for 2 more minutes, or until they begin to wilt. Add the green onions and onions to the bowl along with the noodles.

Cook the omelette until it is opaque. Transfer to a cutting board. Cut the omelette into thin strips by rolling it up. Set aside.
  • Add the mushrooms to the same pan. Cook the mushrooms for 3 minutes, or until they are softened and golden brown. Transfer to the bowl with the noodles.
  • Garlic and meat: Heat oil in the same pan. Add the garlic. Cook the garlic for 30 seconds, or until it is fragrant. Cook the marinated meat for 2 minutes, or until it is brown and opaque. Transfer meat to a bowl with the noodles.
  • Mix the seasoning again before adding to the noodle bowl. Combine all ingredients with the noodles and mix until well coated. You can taste the japchae before you add salt or more seasoning.
