Korean Soybean Stew (Doenjang Jjigae)

Korean soybean stew, or doenjang jjigae, is a bubbling, savory stew made with fermented soybean paste, tofu, and vegetables. This version uses a quick kelp-and-shiitake broth, which adds depth without fish; Korean households make many variations, changing the vegetables and broth to suit the season or what is on hand.

Ingredients

4 cups (960 ml) water
1 piece dried kelp, about 2 by 2 inches (5 by 5 cm; 4–5 g)
2 dried shiitake mushrooms (about 12 g)
3 tablespoons (51 g) Korean doenjang (fermented soybean paste)
1 medium potato, peeled and cut into ½-inch (1.25 cm) cubes (about 200 g)
½ medium yellow onion, cut into bite-size pieces (about 75 g)
1 small zucchini, quartered lengthwise and sliced (about 200 g)
1 cup (70 g) sliced fresh mushrooms, such as shiitake, cremini, or oyster
2 garlic cloves, finely chopped (about 6 g)
12 ounces (340 g) medium-firm or firm tofu, cut into ¾-inch (2 cm) cubes
1 teaspoon (2 g) gochugaru (Korean red pepper flakes), optional
1 small green Korean chile or jalapeño, thinly sliced, optional
1 scallion, thinly sliced (about 15 g)
1 teaspoon (5 ml) soy sauce, only if needed to adjust the finished stew

Instructions

Prepare the broth. Add the water, dried kelp, and dried shiitake mushrooms to a medium saucepan or stew pot. Bring to a boil over medium-high heat, then lower the heat and simmer gently for 10 minutes. Lift out and discard the kelp. Remove the shiitakes, slice them thinly once cool enough to handle, and set them aside for the stew. Keep the broth in the pot.
Season the broth. Put the doenjang in a small bowl and whisk in a ladleful of hot broth until it loosens into a smooth mixture. Return it to the pot and stir in the garlic and gochugaru, if using. Bring the broth back to a gentle simmer, about 2 minutes. Doenjang varies in saltiness, so do not add salt at this stage.
Cook the potato. Stir in the potato and simmer uncovered for 8 minutes. Keep the stew at a steady, gentle bubble rather than a vigorous boil; the potato should begin to soften around the edges but not fall apart. Stir once or twice, scraping the bottom of the pot so the paste does not settle and scorch.
Add the vegetables. Add the onion, zucchini, fresh mushrooms, and the sliced rehydrated shiitakes. Simmer for 6 minutes, stirring gently once or twice. The vegetables should become tender while still holding their shape. If the broth looks unusually low, add a small splash of water; the finished stew should be substantial, not dry, but it is traditionally served with a spoonful of broth in each portion.
Add tofu and finish. Slide in the tofu and optional chile. Simmer gently for 4 minutes, just long enough to heat the tofu through and let it take on some of the broth’s flavor. Taste a spoonful. If it needs more salt, stir in up to 1 teaspoon soy sauce; if it is already nicely savory, leave it as it is. Scatter the scallion over the top and serve hot.

Tips

Choose the right paste. Korean doenjang is a fermented soybean paste with a robust, earthy, salty flavor. It is not interchangeable with gochujang, which is sweet, spicy, and made with red chile. If doenjang is hard to find, use 3 tablespoons (about 51 g) of white or yellow miso plus 1 teaspoon (5 ml) soy sauce. The result will be milder and a little sweeter, so taste before adding any extra seasoning.
Keep the simmer gentle. A rolling boil can break up the tofu and make the vegetables mushy. Stir from the bottom occasionally because soybean paste can settle and catch, especially in a thin pot. If your pot tends to scorch, use a heavy-bottomed saucepan and lower the heat as soon as the stew simmers.
Cut vegetables to cook evenly. Keep the potato cubes close to ½ inch (1.25 cm), and slice the zucchini into similar bite-size pieces. Larger potato pieces may need several extra minutes; very thin zucchini slices can collapse before the potato is ready. If your potato is especially large, cut the cubes a little smaller rather than extending the simmer dramatically.
Adjust salt at the end. Doenjang brands differ, and the broth reduces slightly as it cooks. Taste before reaching for soy sauce, salt, or more paste. If the stew tastes too concentrated, add water a few tablespoons at a time; if it tastes flat, a small additional spoonful of doenjang can bring back its fermented savoriness.

Serving Suggestions

Serve the stew hot in individual bowls or set the pot in the middle of the table while it is still gently bubbling. Steamed short-grain rice is the classic partner: its mild flavor balances the salty, deeply savory broth, and it can be eaten alongside the stew or spooned into the bowl. Offer small Korean-style side dishes such as kimchi, seasoned spinach, or pickled radish if available, but none is required for a satisfying meal.

Because doenjang can be quite salty, keep additional salty sides modest and let diners add more heat at the table with sliced chile or gochugaru. A simple plate of sliced cucumber or lightly dressed greens also gives the meal a fresh contrast. Put out a spoon for the broth and chopsticks for the tofu and vegetables; the stew is meant to be eaten as part of a meal, not drained like a dry stir-fry.

Variations

Make it vegetarian or vegan: This recipe is already plant-based when the doenjang contains no added fish ingredients. Check the label if you are cooking for someone who avoids fish, since some pastes or prepared broths may include seafood. The kelp and shiitake broth gives the stew savory depth without anchovies.

Use different vegetables: Replace the zucchini with Korean radish, daikon, or a small piece of pumpkin or kabocha squash. Cut firm vegetables into small pieces and add them with the potato so they have enough time to soften. Tender greens, such as spinach, can go in during the final minute instead. Enoki mushrooms can be added with the tofu because they cook quickly.

Make it spicier: Increase the gochugaru to 2 teaspoons (4 g), or add another thinly sliced chile. Gochugaru gives a rounded, warming heat; fresh chile tastes sharper. For a less spicy pot, omit both and serve chile separately so everyone can adjust their own bowl.

Make a heartier stew: Add ½ cup (75 g) cooked soybeans or ½ cup (75 g) sliced zucchini and mushrooms in addition to the amounts listed. For another traditional-feeling texture, use a little more potato or tofu. Family and regional versions vary, so treat the vegetable list as flexible while keeping enough broth and doenjang to season the pot.

Storage and Reheating

Let leftovers stop steaming, then transfer them to a shallow, covered container and refrigerate within 2 hours of cooking. They keep for 3–4 days in the refrigerator. The potato and zucchini will soften as they sit, and tofu may become slightly firmer, but the flavor often becomes more rounded by the next day. If you expect leftovers, you can also keep a little extra broth or water on hand to loosen the stew when reheating.

Reheat only the portion you plan to eat in a saucepan over medium-low heat, stirring gently until it is steaming throughout. For food safety, USDA FSIS advises reheating leftovers to 165°F (74°C); check the center with a food thermometer. Add a splash of water if the broth has thickened, and avoid a hard boil that could break up the tofu. Refrigerate any remaining portion promptly rather than repeatedly warming the whole pot. For longer storage, freeze in airtight containers for up to 2–3 months for best quality; thaw overnight in the refrigerator and expect the vegetables and tofu to be softer after thawing.

Frequently Asked Questions

Is Korean soybean stew the same as doenjang jjigae?
Yes. Doenjang jjigae is the Korean name commonly used for this style of stew, with doenjang meaning fermented soybean paste and jjigae referring to a Korean stew. Recipes differ from household to household, especially in their broth, vegetables, and level of chile.

Can I make this without kelp or dried shiitake?
Yes. Use 3 cups (720 ml) water or unsalted vegetable broth in place of the prepared broth. The stew will still be flavorful because doenjang is its main seasoning, though it will have less of the subtle, savory depth from kelp and mushrooms. Avoid a strongly flavored stock that competes with the paste.

Can I use soft tofu?
You can, but it is delicate and more likely to break when stirred. Medium-firm or firm tofu holds its shape best in a bubbling stew. If using soft tofu, add it in large spoonfuls at the end and move the pot gently instead of stirring through it.

How can I tell when the stew is done?
The potato should be tender when pierced with a fork, the onion and zucchini should be soft but recognizable, and the tofu should be hot through. If the potato is still firm after the listed time, simmer for another 2–3 minutes and check again. The broth should taste savory and balanced, not harshly salty.

Can I prepare doenjang jjigae ahead?
Yes. You can make the broth and chop the vegetables earlier in the day, keeping them covered and refrigerated separately. For the freshest texture, cook the stew shortly before serving. If the full stew is made ahead, refrigerate it promptly and reheat portions gently to 165°F (74°C), adding a little water if needed.
