Jajangmyeon holds a special place in my heart, and I often crave it. My parents would treat me to Korean black bean noodles at our neighborhood Korean-Chinese restaurant whenever I memorized my times tables perfectly. I think I was in 3rd or 4th grade. As you can tell, I wasn’t exactly a math genius!

You can’t resist the thick, chewy wheat noodles covered in rich, savory black bean sauce. It’s Korea’s version of mac ‘n cheese – total comfort food!

Slurping noodles with black bean sauce often leaves dark smears around your mouth, just like you wouldin K-dramas, but who cares about how you look when you’re in noodle heaven? Your napkins will take care of it at the end.

With this recipe, you can enjoy authentic restaurant-quality jajangmyeon using store-bought wheat noodles, black bean paste, and a hint of lard. Yes, Lard!

You’ll understand why so many Koreans are nostalgic about it. Who knows, they might have gotten the same jajangmyeon reward for memorizing their times tables.

What is Jajangmyeon?

Jajangmyeon (자장면), or Jjajangmyeon (짜장면), is a popular Korean-Chinese noodle dish. It consist of chewy wheat noodles smothered in a savory sauce made from chunjang (춘장), a fermented Korean black bean paste.

The dish has a deep, savory taste from the black bean sauce that’s a little bit sweet and a little bit salty. The sauce is thick and clings to the chewy noodles. Each bite gives you a hearty flavor that’s really satisfying, kind of like a really good spaghetti but with its own unique Korean twist.

The Origin

Adapted from the Chinese dish ‘Zhajiangmian’ by early Chinese immigrants in the late 19th century, jajangmyeon quickly became popular in Korea, especially in Incheon. Made with chunjang, a fermented black bean paste, it was a cheap meal for urban workers and a must-have at celebrations.

In the ’70s and ’80s, Korean-Chinese restaurants made jajangmyeon a staple across Korea. The ’90s introduced instant jjajangmyeon, making it easy to enjoy at home. Today, it’s as common as pizza delivery in the U.S., especially on moving days. It’s also popular on Black Day (April 14th), when singles eat jajangmyeon together.

The Noodles

Noodles are key to jajangmyeon’s chewy, bouncy texture. While hand-pulled noodles are the gold standard, various commercial wheat noodles also do justice to the dish’s hearty sauce.

You can buy these wheat noodles easily at most Asian grocery stores, usually labeled as udon and jajangmyeon (우동 짜장면) or jungwhamyeon (중화면).

For the best texture, look for fresh noodles in the refrigerator section of Asian grocery stores or Korean markets. However, if you’re in a pinch and can’t find these specific types, udon noodles or dried spaghetti make acceptable substitutes.

Just keep in mind that dried noodles may not hold their shape as well as their fresh counterparts once cooked.

Jajangmyeon Sauce

Jajangmyeon sauce is made from a thick, sweet, and savory black bean paste called ‘chunjang.’ It’s stir-fried with diced pork, vegetables like onions and sometimes zucchini or potatoes, and a bit of sugar to add sweetness.

This mixture is simmered until until they are soft and the flavors meld into a rich, thick sauce that’s dark, almost black. This sauce is then poured over noodles to create the classic jajangmyeon dish.

Ingredients

Ingredients for making jajangmyeon recipe.

Besides the jajangmyeon noodles, you’ll need the following ingredients:

  • Pork: Choose loin or shoulder cuts for the best texture.
  • Chunjang: The key to authentic jajangmyeon is this Korean black bean paste, Fry it in oil or pork fat to create the rich jajang sauce.
    • It is available in jars or packets at Korean markets usually found in the same isle with gochujang and doenjang pastes.
    • You can also find pre-roasted chunjang , which is ready to use without extra frying.
  • Lard: Use it to add depth to your sauce, or choose oil for a lighter version.
  • Asian Leek or Green Onion: These bring a subtle sharpness and fragrance to the dish.
  • Mixed Vegetables: Typically onions, cabbage, and zucchini are used for their complementary flavors and textures.
  • Oyster Sauce: Adds a touch of umami and depth.
  • Cornstarch Slurry: A simple blend of cornstarch and water that thickens the sauce.

Note: Avoid using Chinese black bean paste; it’s different and will change the flavor of the dish. If you like Chinese black bean flavors, see my recipes for Chinese Beef and Pepper Stir-fry or Twice Cooked Pork.

How to Cook Jajangmyeon

Prep chunjang paste

  • Heat some oil or a large skillet in a wok on medium-low heat, then add the chunjang paste. Stir-fry it for 2 to 3 minutes.
  • After that, use a fine mesh strainer to transfer the paste to a small plate and put it aside. Get rid of the oil and give the wok a quick clean.

Stir-fry pork and aromatics

  • Warm up the lard in the wok over medium-high heat. Toss in the leek and sugar, stir-frying until the leek begins to caramelize.
  • Then, add the pork and continue cooking until it’s fully cooked and no pink remains.

Add vegetables

  • Add the cabbage and onion to the wok, cooking them until they start to soften. Throw in the zucchini pieces and give everything a good stir.
  • Then, blend in the set-aside chunjang paste and oyster sauce, making sure all the meat and vegetables are evenly coated.

Thicken the sauce

  • Add water and chicken bouillon powder to the mixture, stirring thoroughly. Bring the sauce to a boil and let it cook for 3 minutes.
  • Then, stir in the starch slurry and cook until the sauce reaches a thicker consistency.

Cook the noodles

  • Boil the noodles in a large pot of water, following the instructions on the package.
    • To achieve chewier noodles, add a splash of cold water each time the water reaches a rolling boil.
  • Once cooked, drain the noodles and divide them into individual serving bowls. Then, mix in the sauce.

How to serve

Place noodles in each serving bowl and ladle the jajang sauce over them. Garnish with julienned cucumber if desired. You can also serve the sauce over cooked rice, called jjajangbap (짜장밥).

Many enjoy adding a fried egg on top of their jajangmyeon, although this is a matter of personal taste. Most importantly, be sure to eat it quickly before the noodles become too soft — soggy noodles are not enjoyable!

My Best Cooking Tips

  1. Pre-fry the Chunjang Paste in Oil: To enhance the flavor of the sauce, fry the black bean paste in hot oil for 2-3 minutes.
    • This step helps eliminate any bitter taste and creates a more delicious sauce.
  2. Opt for lard when possible: Using lard in your recipe will contribute a deeper, richer flavor to the sauce.
    • If lard is unavailable, you can use oil as a substitute.
  3. Add a Savory Kick: Use Asian leek or green onion for extra umami. Sauté Asian leek or green onion in lard or oil, along with a little amount of sugar, to impart a savory taste.
    • The sugar caramelizes the leek slightly and integrates a smoky flavor into the sauce.
  4. Use Chicken Bouillon Powder: A pinch can add a complex undertone to the sauce.
    • Alternatively, use chicken stock in place of water for the same rich flavor.

What to eat with jajangmyeon

Enjoying Korean noodles with black bean sauce is often a feast of flavors, and it’s commonly paired with complementary dishes that enhance the experience:

  • Danmuji (Yellow Pickled Radish): The sweet and tangy crunch of Asian pickled radish cleanses the palate between bites of the savory noodles. Find danmuji at Korean grocery stores or Asian markets, available either whole or sliced into convenient rounds.
  • Pa-Kimchi: A classic Korean kimchi made with green onions, its spicy and fermented flavors balance the richness of jajangmyeon perfectly.
  • Tangsuyuk (Sweet and Sour Pork): The crispy, sweet, and sour flavors of tangsuyuk provide a delightful textural and flavor contrast to the creamy jajangmyeon sauce.
  • Jjamppong (Spicy Seafood Noodle Soup): If you love a variety of noodles, jjamppong offers a spicy contrast to the sweet and savory jajangmyeon.

Instructions 

For Jajangmyeon Sauce

  • To pre-fry Korean black bean paste (chunjang), heat oil in a wok over medium-low heat, and add chunjang paste. Stir-fry for 2-3 minutes. Use a fine mesh strainer to scoop the paste onto a small plate and set aside. Discard the oil and clean the wok.
  • Heat lard in the wok over medium-high heat. Add the leek and sugar, stir-frying until the leek is slightly caramelized. Add pork and cook until no longer pink.
  • Stir in cabbage and onion, cooking until slightly softened. Add zucchini pieces and toss. Mix in the reserved chunjang paste and oyster sauce, ensuring that all meat and vegetables are coated evenly.
  • Pour in water and chicken powder, stirring well. Bring the sauce to a boil and cook for 3 minutes. Add the starch slurry and cook until the sauce thickens.

For Noodles

  • Meanwhile bring a pot of water to boil. Add the noodles and cook according to the package direction, and drain. Be careful not to overcook them.
  • Place a portion of noodles in each bowl and ladle the sauce over them. Garnish with optional cucumber matchsticks, if desired. Alternatively, you can serve the sauce over cooked rice, creating a dish known as jjajangbap (짜장밥).
    Note: Jjajangmyeon is traditionally accompanied by pickled radish slices. However, a modern twist involves pairing the dish with green onion kimchi (pa kimchi), which creates a delightful combination.

Notes

Where to find jajangmyeon noodles: You can typically find it at most Asian grocery stores, where they may be labeled as udon and jajangmyeon (우동 짜장면) or jungwhamyeon (중화면). I recommend looking for fresh noodles in the refrigerator section, as they tend to have a better texture. If these noodles are not available, udon noodles or dried spaghetti noodles can be used as a substitute.
