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.

Jjajangmyeon: Thick Noodles in Black Bean Sauce

Jjajangmyeon (짜장면), also spelled jajangmyeon (자장면), has roots in Chinese zhajiangmian, but in Korea it evolved into a distinct comfort dish with its own flavor and style. If you dine in Korean-Chinese restaurant, you will find people eating this noodles paired with other dishes like Jjamppong (spicy seafood noodle soup) and Tangsuyuk (sweet and sour pork).

The dish is made with wheat noodles and a thick black bean sauce built from chunjang (춘장). The sauce is cooked with pork and vegetables, then poured over the noodles just before serving.

What makes it stand out is the texture. The sauce is dense and glossy, and it coats each strand of noodle rather than soaking in. That contrast between chewy noodles and rich sauce is what gives jjajangmyeon its signature bite.

At home, the key is getting that sauce right. Once the chunjang is properly fried and balanced, the rest comes together quickly on the stovetop.

Choosing the RIght 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.

Key Ingredients for Jjajangmyeon

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. Avoid using Chinese black bean paste; it’s different and will change the flavor of the dish.
    • 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.

How to Cook Jajangmyeon

Fry the chunjang to remove bitterness. Push the pork aside and cook the black bean paste in oil for a few minutes. This step is key to getting a smooth, rich sauce.

Cook the pork until lightly browned. Start by sautéing the pork in oil or lard until it begins to caramelize. This builds the base flavor for the sauce.

Cook the vegetables. Add the onion, cabbage, zucchini, and Asian leek or green onion, then stir-fry until they start to soften. They should still hold their shape, since they will continue cooking once the liquid goes in.

Simmer until thick and glossy. Pour in the water or stock and let everything simmer so the vegetables, pork, and chunjang come together into one sauce. Once the flavors have melded, stir in the cornstarch slurry and cook until thick and glossy.

Serve with freshly cooked noodles. Spoon the sauce over hot noodles just before serving so the noodles stay chewy and the sauce coats them well.

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). This noodle is always accompanied by danmuji (pickled radish), and some like to serve with green onion kimchi as well.

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

  • Fry the chunjang properly: Cooking the black bean paste in oil for a few minutes removes bitterness and deepens the flavor. Don’t skip this step, or the sauce can taste flat.
  • Use lard for deeper flavor: Lard gives the sauce a richer, more rounded taste. Oil works, but you’ll notice the difference if you’ve tried both.
  • Build flavor with aromatics: Asian leek or green onion adds a subtle savory depth. Let it cook slightly with a bit of sugar to bring out a mild caramelized note.
  • Boost umami if needed: A pinch of chicken bouillon powder or using stock instead of water can add extra depth, especially if your chunjang is on the lighter side.

  • 2 tbsp (30 g) lard, or oil
  • ½ cup (60 g) chopped Asian leek, or green onion

  • ½ lb (225 g) pork, chopped into small pieces
  • ¼ about 5 oz (150 g) small cabbage, chopped

  • 1 tbsp (8 g) cornstarch , mixed with 3 tablespoon water (45 ml)
  • ¼ cucumber, sliced to matchsticks to garnish, optional

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.
