Kongjaban or Kongjang was my all time favorite lunchbox banchan (side dish) when I was a kid. My most happy lunchbox(도시락 doshirak) always included at least 2 of the following: Kongjaban, Sauteed string potatoes, Jangjorim, Oeji (pickled cucumbers) and Gim (roasted sea laver). My school day mornings passed by more quickly and happily when I knew I had these in my lunchbox… 🙂
Usually, kids don’t like beans very much. I certainly remember not liking any kind of beans mixed in my rice when I was little. I never liked the mushy texture of cooked beans and also the fact that it kind of had no flavor. But the balance of sweetness and saltiness (you know that ‘sweet and salty’ is one of my favorite flavor combination, right?) and the not-mushy texture of this Kongjaban made it all different.
If done right, these Sweet and Salty Soybeans (Kongjaban 콩자반) can be so delicious. Sadly, there are too many not-so-good Kongjabans served at restaurants or sold at markets that give this dish a bad name. PLEASE believe me – that’s not how the dish is supposed to taste. The soybeans are usually too soft and mushy or too hard and the sauce is so bland that it basically tastes like nothing.. Sad sad sad..I bought one or two ready made, packaged Kongjaban and also one from a banchan corner at the Korean market and as I expected, quite flavorless…
Try making these soybeans at home for yourself and see how you like them.
Anyways, let’s get started –
Sweet and Salty Soybeans (Kongjaban or Kongjang)
Servings: 8-10 Prep Time: 5-6 hrs Cooking Time: 1 hr Difficulty: Easy
Ingredients
- 2 C soaked or 3/4 C dry black soy beans (서리태 Seoritae)
- 3 C or more water
- 5 T soy sauce (jinkanjang 진간장)
- 4 T sugar
- 2 C cooking liquid from beans
- 2 tsp maple syrup or rice malt syrup
Directions
- Soak the dry soybeans in 2 C of water 5~6 hrs or overnight. The soaking time can vary depending on the temperature. Warmer temps require less time (3~4 hrs) and colder temps require more (8~12 hrs).
FYI, here’s a close up of dry vs soaked black soy beans:
- Drain the liquid from the soaked soybeans and add to pot with 3 1/2 C of water. Bring to a boil. Once it boils, lower heat to medium and cook UNCOVERED for approx 12 minutes until the beans are fully cooked. Soybeans should be soft but still slightly crunchy and not mushy.
- Drain the cooked soybeans while reserving the cooking liquid.
- In a pot, add 2 C of the cooking liquid + soy sauce + sugar and bring to boil over med-high heat.
- Add the soybeans to the boiling soy sauce liquid and lower heat once it starts to boil like below. Simmer for 25 min, stirring often. Lower the heat if you find that the liquid is reducing too quickly.
- Add maple syrup to add shine and additional sweetness. Cook for another 20 min (stir often) or so until the sauce is reduced and the color has turned dark brown like below:
And so there you go! It’s pretty simple, no? Let it cool and store in a container at room temperature for 2-3 days or in your fridge for many days. Serve at room temp or can be eaten cold out of the fridge. Enjoy it with some plain rice or as a side dish to go with other spicy dishes. As I said, it makes a great side dish in kid’s lunchboxes!

This looks so good. I want to try it with peanuts since they’re the easiest for me to acquire. should the peanuts be raw?
JinJoo says
That’s a fun idea! I haven’t made it myself but if you are going to use raw peanuts with skin on, it would be best to flash boil it first and then cook with the sauce. Thank you!
Karen says
the idea is from the list of substitutions here on your blog. it says mung beans are an option as well.
JinJoo says
Oh! My..yes of course! I wrote this post 10+ years ago and I forgot that I mentioned it… lol. Thank you for letting me know. Let me know how you like it with peanuts.
Gary Neal Hansen says
Thanks!
The ingredients call for reserved soaking liquid.
The step by step instructions call for reserved cooking liquid.
Which should it be?
JinJoo says
Hi Gary – so sorry for the confusion! It should be the cooking liquid. I made the correction – thank you so much for asking.
Diane says
yum, perfectly cooked and perfectly seasoned!
