Jjajangmyeon (짜장면): Korean Black Bean Noodle Recipe

Thick, chewy noodles in a glossy, savory black bean sauce loaded with pork and vegetables Korea's most beloved delivery food.

There's a Korean dish so iconic that it has its own holiday. On April 14th exactly one month after Valentine's Day singles in Korea gather to eat jjajangmyeon and commiserate about being alone. The day is called Black Day, and the dish is jjajangmyeon: thick wheat noodles topped with a glossy, dark, savory black bean sauce.

But jjajangmyeon isn't just for singles. It's Korea's most popular delivery food, the dish that appears at every Chinese-Korean restaurant, and the comfort meal that generations of Koreans grew up eating. It's sweet, savory, slightly smoky, and deeply satisfying the kind of food that feels like a hug in a bowl.

What makes jjajangmyeon special is its sauce. It's made from chunjang (Korean black bean paste), which is stir-fried with pork, onions, zucchini, and potatoes until it becomes rich, glossy, and deeply caramelized. The result is a sauce that's savory, slightly sweet, and impossible to stop eating.

This guide covers everything: what jjajangmyeon actually is, its fascinating history, how to handle the black bean paste, and a detailed step-by-step recipe that gets you as close to a Korean-Chinese restaurant as you can get at home.

What Is Jjajangmyeon, Exactly?

Jjajangmyeon (짜장면) is a Korean-Chinese noodle dish made with thick wheat noodles topped with a thick, savory sauce made from chunjang (black bean paste), diced pork, onions, zucchini, potatoes, and sometimes cabbage. The name literally means "fried sauce noodles" (jja = fried, jang = sauce, myeon = noodles).

It's a Korean adaptation of the Chinese dish zhajiangmian, which was brought to Korea by Chinese immigrants in the late 19th and early 20th centuries. Over time, Korean cooks adapted the dish to local tastes using Korean chunjang instead of Chinese sweet bean paste, adding more vegetables, and making the sauce sweeter and milder.

Today, there are several popular styles:

• Classic jjajangmyeon thick noodles with a pork and vegetable black bean sauce. The standard version.
• Gan-jjajang (간짜장) the sauce is stir-fried to order and served separately from the noodles. The sauce is thicker and more intensely flavored.
• Samseon jjajang (삼선짜장) made with seafood (shrimp, squid, and sometimes sea cucumber) instead of pork. A premium version.
• Jjajang-bap the same sauce served over rice instead of noodles. Popular for those who prefer rice.

This recipe focuses on the classic pork and vegetable version, because it's the most iconic and the one most people mean when they say "jjajangmyeon."

Why This Recipe Works

Most homemade jjajangmyeon fails for one of three reasons: the sauce is bitter and harsh, the vegetables are soggy, or the whole dish is greasy and one-dimensional. This recipe solves all three:

• Stir-frying the chunjang first this is the most important step. Raw chunjang is bitter and harsh. Frying it in oil for 2–3 minutes removes the bitterness and brings out its deep, savory flavor.
• Cooking the vegetables in stages onions, zucchini, and potatoes have different cooking times. Adding them in the right order keeps each one tender but not mushy.
• A touch of sugar and oyster sauce these balance the saltiness of the chunjang and add depth. Without them, the sauce tastes flat.

Ingredients (Serves 3–4)

For the sauce:

• 4 tbsp chunjang (Korean black bean paste)
• 2 tbsp neutral oil (for frying the paste)
• 200g pork belly or pork shoulder, diced into small cubes
• 1 large onion, diced
• 1 zucchini, diced
• 1 potato, diced
• 1/2 cup cabbage, chopped (optional)
• 1 tbsp minced garlic
• 1 tbsp grated ginger
• 2 tbsp soy sauce
• 1 tbsp oyster sauce (optional)
• 1 tbsp sugar
• 1 tbsp rice wine (mirin) or cooking sake
• 2 cups water or chicken stock
• 1 tbsp cornstarch mixed with 2 tbsp water (slurry)
• 1 tsp sesame oil

For the noodles:

• 400g fresh jjajangmyeon noodles (or thick wheat noodles)
• Salt for the boiling water

For serving:

• 1 cucumber, julienned
• 1/2 onion, thinly sliced (optional)
• Pickled radish (danmuji), sliced
• Optional: a fried egg or sliced omelet
• Optional: gochugaru (Korean red chili flakes) for heat

Note: Chunjang (Korean black bean paste) is essential for jjajangmyeon. It's available at Korean grocery stores or online. Don't substitute with Chinese sweet bean paste the flavor is completely different.

Step-by-Step Recipe

Step 1: Fry the Chunjang

Heat 2 tablespoons of neutral oil in a pan or wok over medium heat. Add the chunjang and stir-fry for 2–3 minutes, until it becomes fragrant and slightly darker. You'll see it bubble and smell a deep, savory aroma. Be careful not to burn it if it starts to smoke, lower the heat. Remove the fried chunjang from the pan and set it aside. This step is essential for removing the bitterness of raw chunjang.

Chunjang tip: If you want an even smoother sauce, you can blend the fried chunjang with a little water before adding it back to the pan. This is optional but gives a more restaurant-style consistency.

Step 2: Cook the Pork

In the same pan, add the diced pork and cook over medium-high heat for 3–4 minutes, until browned and slightly crispy. Add the minced garlic and grated ginger and cook for 1 minute, until fragrant.

Step 3: Add the Vegetables

Add the onion, zucchini, potato, and cabbage (if using) to the pan. Stir-fry for 3–4 minutes, until the vegetables are slightly softened but still have a little bite. Add the soy sauce, oyster sauce, sugar, and rice wine. Stir well to combine.

Step 4: Add the Chunjang and Water

Return the fried chunjang to the pan and stir well to combine with the pork and vegetables. Add 2 cups of water or chicken stock. Bring to a simmer and cook for 5–7 minutes, until the vegetables are fully tender and the sauce has thickened slightly.

Step 5: Thicken the Sauce

Stir the cornstarch slurry again and add it to the pan, stirring constantly. Simmer for 1–2 minutes, until the sauce thickens to a glossy, pourable consistency. It should coat the back of a spoon but still flow. Add the sesame oil and stir. Taste and adjust the seasoning add more sugar if it's too salty, more soy sauce if it's too mild.

Step 6: Cook the Noodles

While the sauce simmers, bring a large pot of salted water to a boil. Add the jjajangmyeon noodles and cook according to the package instructions usually 3–4 minutes for fresh noodles. Drain and rinse briefly under warm water to remove excess starch. Divide the noodles among bowls.

Step 7: Assemble and Serve

Ladle the sauce generously over the noodles. Top with julienned cucumber and sliced onion (if using). Serve with pickled radish (danmuji) on the side. To eat, mix the sauce and noodles together thoroughly the sauce should coat every strand. If you like it spicy, add a pinch of gochugaru.

How to eat jjajangmyeon: Mix everything together before eating. The cucumber adds a fresh crunch that cuts through the richness of the sauce. In Korea, jjajangmyeon is often served with a side of raw onion and black bean paste for dipping, and a bowl of hot broth to cleanse the palate.

Popular Variations to Try

• Gan-jjajang (간짜장) stir-fry the sauce to order and serve it separately from the noodles. The sauce is thicker and more intensely flavored.
• Samseon jjajang (삼선짜장) substitute the pork with seafood (shrimp, squid, and sometimes sea cucumber). A premium version.
• Jjajang-bap serve the same sauce over rice instead of noodles. Popular for those who prefer rice.
• Vegetarian jjajangmyeon skip the pork and use mushrooms or tofu instead. Just as delicious.
• Spicy jjajangmyeon add gochugaru or a splash of chili oil to the sauce for a spicy version.

Tips for the Best Jjajangmyeon

• Fry the chunjang first. This is the most important step. Raw chunjang is bitter and harsh. Frying it removes the bitterness and brings out its deep, savory flavor.
• Use pork belly or shoulder. Pork belly adds richness and flavor. Pork shoulder is leaner but still works well.
• Dice the vegetables evenly. Evenly sized pieces cook at the same rate and give the sauce a consistent texture.
• Thicken with cornstarch slurry. This gives the sauce its glossy, restaurant-style consistency. Add it slowly and stir constantly.
• Serve with cucumber and danmuji. The fresh cucumber and tangy pickled radish cut through the richness of the sauce. Don't skip them.
