About this dish

Kkotge tang doenjang is a Korean blue crab stew that uses a full 800g of crab simmered in a doenjang-forward broth, where fermented soybean paste and the crab's natural essence are the two dominant flavors.

As the shells cook, they release a deeply savory stock, and radish, zucchini, and onion simmer in that liquid and add layers of sweetness and body. Unlike the more common spicy gochujang-based crab stews, this version leads with doenjang's earthy depth and fermented complexity. Gochugaru and Cheongyang chili provide a secondary heat that balances the richness without taking over. Adding tofu keeps the texture varied and lightens the heaviness of the broth slightly. The crabs turn a vivid orange as they cook, a reliable visual cue that the meat is ready to pull cleanly from the shell. The fermented character of the doenjang suppresses any fishy edge from the crab, making the stew approachable even for those who do not normally gravitate toward shellfish. Served with rice to soak up the broth, it makes a satisfying complete meal.

Instructions

Read the steps as a cooking flow: prep, heat, seasoning, doneness control, and finish.

6 steps

1

Prep

Scrub 800g of thawed blue crab right away with a kitchen brush, then remove the belly flaps.

Cut each body in half with kitchen shears so the shells can release flavor into the broth evenly.
2

Finish

Slice 200g of Korean radish into 0.5cm pieces so it cooks before the crab finishes.

Cut 120g zucchini and 100g onion into bite-size pieces, then slice the green onion and Cheongyang chili diagonally into 1cm pieces.
3

Control

Put 1100ml water and the radish in a pot and bring it to a boil over high heat.

Once boiling, lower to medium and cook for about 7 minutes, until the radish edges start turning translucent.
4

Season

Press 1.5 tablespoons doenjang through a strainer into the broth so no salty clumps remain.

Add 1 tablespoon minced garlic and 1 tablespoon gochugaru, then bring the broth back to a steady boil.
5

Control

Add the prepared crab and simmer over medium heat for about 8 minutes.

Skim off foam as it rises for a cleaner broth, and cook until the shells turn orange and the raw seafood smell fades.
6

Control

Add the zucchini and onion and simmer for 5 more minutes, just until tender but not collapsing.

Add the green onion and Cheongyang chili for the final minute, then check the broth seasoning before serving with rice.
