Jajangmyeon (Black Bean Sauce Noodles)

Jajangmyeon is a very popular noodle dish in Korea that is made with Chinese black bean paste (Chunjang), meat and veggies. A great one-dish meal any time or any day of the week!

Noodles in Black Bean Sauce (Jajangmyeon)

What is Jajangmyeon?

Jajangmyeon (짜장면) or Jjajangmyeon is a Chinese Korean noodle dish that is topped with a thick savory black bean sauce with meat and/or seafood and vegetables. This dish is very popular among Koreans, especially children because it’s not spicy but delicious.

The noodles for this dish was traditionally hand-pulled and thus called Suta Jajangmyeon 수타 짜장면. Hand-pulled means that you pull and stretch the dough and fold and repeat until you get hundreds of thin strands of the dough. Unfortunately, the fresh hand-pulled noodles are very hard to find anymore.

I have been making this dish at home since 91′ after I got married (over 20 years?!) at the request of my husband. My recipe has evolved quite a bit over the years and I have to say I’m quite happy with this one. When I gave it to my daughter for tasting, she happily chanted “Your Jajangmyeon tastes better than the one at the restaurant we visited!”. And if you are allergic to MSG, my version does NOT need any so you are good there.

History of Jajangmyeon

According to one story was introduced in 1905 by a Chinese chef at Gonghwachun (공화춘; 共和春), a Chinese restaurant in Incheon Chinatown settled by early Chinese immigrants from the Shandong Province of China. Since then, it has fully become part of the Korean culture, invoking all sorts of memories for many Koreans young and old.

The other story says that no one knows for certain who introduced it first but the dish came about because the Chinese immigrants who worked at the Incheon pier in the 1890’s needed something quick and cheap to eat.

In 2012, I visited Incheon and also visited the Jajangmyeon museum and here are some pictures that I took.

From top left to right: picture of Incheon Chinatown and tourists; the chef + delivery man sculpture in front of the museum; the inside of the most famous Jajangmyeon restaurant (feels like I was in a Chinese martial arts movie); antique steel carrier used for delivering Chinese food.

So… also did you ever notice? In almost every Korean drama, you will see characters devour this black sauce noodle dish-ending with black sauce all around their mouths. And they are always delivered in a version of the steel carrier above which is now sometimes a plastic box.

There’s even a saying among Koreans about how a move to a new home is not complete unless you order Jajangmyeon at the end of a long moving day. For every Korean neighborhood, there’s always a Chinese restaurant nearby and delivery is a must. A few days ago, in one of my TV favorite show – “Dad, where are you going?“(아빠 어디가? Appa Uh-diga?)- I watched this yummy black noodles being delivered to a rice field!!? Whaat??? Even the dads were surprised to see the food when it came. Now, I call that service!!!

I think in many ways, this noodle dish is equivalent to America’s Pizza. If you are up late working in the office or if you have friends over but not sure what to eat, then Koreans order this ultimate comforting dish.

Why do you eat Jajangmyeon on Black Day 4/14th?

So you know about 2/14 being Valentine’s Day. In Korea, there’s an additional day called White Day on 3/14th. So Valentine’s day is when Korean girls buy gifts for boys they like. White Day is for the boys to buy girls gifts. Well.. then what about singles??

Well, Korean singles decided to make 4/14th Black Day!! And on this Black day, singles get together wearing black and eating something black. And Jajangmyeon is the most popular black food to eat this day. I think it also has to do with the fact that you can’t help get your face all messy eating this black noodle dish and if you are a single, what do you care?? LOL.. at least that’s my take on it.

Types of Black Bean Sauce Noodles

간짜장면 Gan-Jajangmyeon – more intense flavor because the sauce is condensed (just black bean paste and vegetables, little water) also more expensive
짜장면 Jajangmyeon – water or broth added to Gan Jajang, so it’s milder in flavor
삼선간짜장면 Samseon-Gan-Jajangmyeon – ‘sam’ means 3 and ‘seon’ means taste. Traditionally, it contains 3 kinds of seafood like squid, sea cucumber and shrimp in addition to pork and veggies.
사천짜장면 Sahcheon-Jajangmyeon – Sahcheon (사천) means Szechuan. as with many things Szechuan, it had added spiciness
유니짜장면 Uni-Jajangmyeon – is made with ground meat instead of cubes which is how it’s mostly done
쟁반 짜장면 Jaengban Jajangmyeon – this is a large shareable noodles served in a round tray (Jaengban)

Best Noodles for Jajangmyeon

The best kind of noodles are the hand-pulled noodles of course by professional Chinese chefs. And then the next best thing is to make my fresh noodles at home. Check out my Kalguksu post on how to make your own noodles. These noodles are not only great for Kalguksu but also works perfectly for this Korean black bean sauce noodles.

Store Bought Noodles

Buy one’s that says “짜장면 국수” but 생칼국수 (Kalguksu/Kalgooksoo) will work too. I buy one from Pulmuone like this one but others work all pretty well. You can also sometimes use 우동 Udon noodles too but just choose one that’s not too thick.

In a pinch, you can even make it with Spaghetti noodles.

Vegan Jajangmyeon

To make your Jajangmyeon vegan, just omit meat and seafood but cut up tofu into little cubes first then pan-fry them in oil until the outside is nicely browned and crispy. Use this browned tofu instead of meat in your recipe and it will still be delicious!

Chef’s Tips

Always pre-fry the Chunjang in lots of oil – if you skip this step, your sauce will come out tasting a bit tart
Customize added ingredients – you can add or swap out vegetables. Many like to add potato and I personally don’t like it but totally up to you. Just don’t omit onions. You can also add squid, shrimps or scallops to the recipe below. Use BEEF stew meat instead of pork if you’d like
Make extra sauce – it keeps for several days in the fridge so just reheat and enjoy later.
Use rice instead of noodles to make Jajangbap or better yet, make simple fried rice and serve it with that.
Add a runny fried egg on top for extra umami!

Step-by-Step Instructions

Servings: 3 Cooking Time: 35 min Difficulty: Medium

Ingredients

1 pack of fresh noodles for Jajangmyeon or kal guksu (or homemade)
1/2 cup Chinese black bean paste (춘장 chunjang/choonjang)
1/3 cup vegetable oil (for sauteeing chunjang)
3 Tbs vegetable oil (for sauteeing veg)
1/2 cup or 3 fresh, dried or fresh shitake mushrooms, chopped (optional)
3 oz (80g) pork loin or pork belly cut into cubes
1 medium size onion, chopped
1 1/2 cup cabbage, chopped
1/2 cup zucchini, chopped

2 green onions, chopped
1/2 cucumber, julienned (as garnish)
1 Tbs sugar
1 cup water
Cornstarch slurry – 1/4 cup water + 1 Tbs cornstarch

Jinmi 춘장 Choonjang (Chinese Black Bean Paste)

In Korea, this Jinmi Chunjang (진미 춘장) is the standard black bean paste used. There are other brands like ShingSong 신송, CJ and they are all similar. There’s also a pre-fried version called Bokkeun Jajang and you can use that one too but I find it doesn’t really replace the step of sauteeing it with oil. They used to have MSG in it but not any more so that’s a good thing. 🙂 READ HERE to learn more about this ingredient.

Start boiling a pot of water to cook the noodles. If using store-bought noodles, cook according to package directions. Usually 7-10 minutes. See my note on noodles above. Or, if you made your own homemade noodles with my Kalguksu recipe, then follow direction over there. But rinse and drain the noodles in cold water when they are cooked. Set aside.
Prepare ingredients below:

Vegetables and pork

2. Chop all vegetables and pork into small cubes. Julienne cucumbers to use as garnish.

Chopped vegetables

3. In a non-stick frying pan, add an equal amount of chunjang and oil to pan on medium/medium-low heat. Should be bubbling but not burning. Stirring often, cook for 7 min.

sauteeing chunjang (jjajang) in pan

Lots of oil will be leftover after stir-frying the paste. Remove chunjang from pan. It should be easy to bunch up the cooked chunjang and remove from oil. Discard leftover oil in the pan.

4. WHILE the chunjang is cooking, in ANOTHER pan, add 2 T oil to pan on medium heat. Sauté just onions and cabbages for 10 min or more until onions become translucent. This will make your sauce taste sweeter!

cooked onions and cabbages

5. Remove onions and cabbages from pan and set aside. Sauté pork on med-high heat for 2-3 min in the same pan.

6. Once pork is cooked, return onions, cabbages to pan. Add 1 T oil and remaining vegetables. Sauté all ingredients on med-high heat for 5 – 7 min. Veggies should still be slightly crunchy.

7. Add the sauteed chunjang paste to pan and stir everything, making sure the paste coats the ingredients evenly.

8. Stir fry for 2 min. Add 1 cup water or chicken broth and 1 Tbs sugar. Mix and simmer for 1-2 min.

9. Add the cornstarch slurry and stir. Keep stirring for 2-3 min. until the sauce thickens. Alternatively, to make Gan Jjajangmyeon, omit the slurry and just cook until the sauce is reduced to half. Reduce further for more condensed flavor.

10. Sauce is now ready!

Just add noodles or rice to a bowl and top with this amazingly yummy sauce, garnish with some julienned cucumbers.

NOTES

How to make Gan Jajangmyeon? – In step 8, instead of adding cornstarch slurry just reduce the sauce until it’s reduced by 1/2.
Chunjang(춘장) and Jajang(짜장) are used interchangeably when referring to the black bean paste. Sometimes you may find 볶음짜장(bokkeum jajang) which means it’s already been fried in oil in which case you can skip step 3.
For a richer sauce, use chicken broth instead of water. Watch out for saltiness though since chicken broth already has quite a bit of sodium. Use low sodium chicken broth or use half broth and half water.

SERVING SUGGESTIONS

Serve a side of Danmuji 단무지 (Yellow pickled radish) and some fresh onions slices with the chunjang as a dipping sauce. These two sides are a must.. Oh and Kimchi too!
Make Gyeran Guk (Korean egg drop soup) and serve together – especially when you are serving rice with black bean sauce.
