Korean Fermented Bean Soup: Doenjang Jjigae Recipe

Korean fermented bean soup, or doenjang jjigae, is a savory Korean stew made with fermented soybean paste, tofu, and vegetables in a warm broth. This version builds flavor with anchovy and kelp, then simmers potatoes, zucchini, and mushrooms until tender; family and regional versions vary in their vegetables, broth, and level of spice.

Ingredients

4½ cups (1.08 L) water, for the broth; add a little more at the end if needed to make 4 cups (960 ml) strained broth.
6 dried Korean anchovies, heads and guts removed if they are large (about 8 g). These make a clear, savory stock; small, cleaned soup anchovies can be used whole.
1 piece dried kelp, about 3 by 3 inches (5 g), also sold as dashima or kombu.
3 tablespoons (54 g) doenjang, Korean fermented soybean paste. Start with this amount, then adjust only after tasting because saltiness varies by brand.
½ medium yellow onion, cut into bite-size wedges (about 75 g).
1 medium potato, peeled and cut into ½-inch (1.3 cm) cubes (about 170 g).
2 garlic cloves, finely minced (about 6 g).
1 small zucchini, cut into half-moons (about 200 g).
4 ounces (115 g) mushrooms, such as shiitake or cremini, sliced. Trim shiitake stems if they are tough.
8 ounces (225 g) firm or medium-firm tofu, cut into ¾-inch (2 cm) cubes.
1 teaspoon (5 ml) toasted sesame oil, optional, for a rounder aroma.
1 teaspoon (2 g) gochugaru, Korean red pepper flakes, optional. Use less for mild soup or leave it out.
2 scallions, thinly sliced (about 20 g), for finishing.

Instructions

Prepare the ingredients. Cut the potato, onion, zucchini, mushrooms, and tofu as listed, and mince the garlic. If using larger dried anchovies, pull off the heads and remove the dark inner guts to reduce bitterness. Keep the tofu aside until the later simmer so it holds its shape.
Make the anchovy-kelp broth. Put the water and dried anchovies in a saucepan and bring to a gentle boil over medium-high heat. Lower the heat and simmer for 8 minutes. Add the kelp and simmer for 2 minutes more; remove the kelp sooner if the water boils vigorously, since prolonged boiling can make it slippery or bitter. Strain out the anchovies and kelp. Measure 4 cups (960 ml) broth for the stew, topping up with water if necessary.
Season the broth. Return the measured broth to a medium pot. In a small bowl, stir the doenjang with a ladleful of warm broth until it loosens, then stir it back into the pot. This helps disperse the paste and prevents dense clumps. Add the garlic, onion, and potato.
Cook the firm vegetables. Bring the pot to a steady simmer, then reduce the heat to medium-low. Simmer uncovered for about 10 minutes, stirring once or twice, until the potato is nearly tender when pierced with a fork. Keep the liquid bubbling gently rather than at a hard boil.
Add the zucchini, mushrooms, and tofu. Stir in the zucchini and mushrooms, then nestle in the tofu cubes. Simmer for 7 minutes, until the vegetables are tender but not falling apart and the tofu is hot throughout. Avoid vigorous stirring, which can break the tofu into small pieces.
Finish and taste. Stir in the sesame oil and gochugaru, if using, and simmer for about 30 seconds to bring the flavors together. Taste a spoonful with a little of the vegetables. If it needs more depth or salt, dissolve another teaspoon of doenjang in broth before adding it; if it tastes too concentrated, add a splash of water.
Serve hot. Scatter the sliced scallions over the pot just before serving. Bring the stew to the table while it is bubbling gently, or ladle it into individual bowls. The broth should taste savory and rounded, not overwhelmingly salty, and the potato should be soft without disintegrating.

Tips

Choose the right paste. Doenjang is the defining ingredient: a strong, salty, fermented soybean paste with a deeper, earthier flavor than most miso. Korean grocery stores often carry several styles. If it is unavailable, use yellow or red miso as a practical substitute, starting with 3 tablespoons (about 54 g); the stew will be milder and often a little sweeter, so it will not taste exactly like doenjang jjigae. Taste before adding extra salt.
Keep the broth gentle. A rolling boil can break up tofu and make the vegetables mushy before the potato cooks evenly. A steady, quiet simmer gives the broth time to take on the paste’s flavor while keeping the vegetables recognizable.
Use a useful broth shortcut. Dried anchovies and kelp are traditional, but they may be hard to find. Replace the homemade broth with 4 cups (960 ml) low-sodium vegetable broth for a vegetarian pot, or water for the simplest option. Vegetable broth gives a rounder flavor than water, but neither has the same sea-savoriness as the anchovy-kelp stock.
Adjust salt at the end. Doenjang varies considerably in saltiness, and broth concentrates slightly as the pot simmers. Do not add extra salt at the start. If you overshoot, add a little hot water and another handful of vegetables or tofu rather than trying to mask the salt with sugar.

Serving Suggestions

Serve doenjang jjigae hot with steamed short-grain rice and a few Korean side dishes, such as seasoned spinach, braised potatoes, or kimchi. Rice is especially useful for balancing the stew’s concentrated savory broth. For a simple meal, put the pot in the middle of the table with rice bowls and let everyone spoon broth and vegetables over their rice. The stew is filling on its own, but it also works as one part of a larger Korean-style meal.

If serving from a shared pot, use a clean ladle and let the stew settle briefly after it comes off the heat; the broth is very hot. A small bowl of sliced scallions or extra gochugaru lets diners adjust their own portions without changing the whole pot. If the stew tastes stronger than expected, serve it with more rice rather than thinning every bowl.

Variations

Make it vegetarian. Use vegetable broth or water instead of anchovy-kelp stock, and check the doenjang label if you need to avoid fish-derived ingredients. Some pastes contain only soybeans, salt, and grains, while products and production practices can differ. The result remains savory, though the broth will have less of the sea-like depth supplied by anchovies.

Change the vegetables. Korean radish, napa cabbage, or a handful of leafy greens can stand in for some of the potato, zucchini, or mushrooms. Cut firmer vegetables small enough to cook in the same time as the potato, and add tender greens in the final few minutes. Use what fits the pot, but avoid adding so many vegetables that the broth no longer covers them well.

Make it milder or hotter. Leave out the gochugaru for a gentler, paste-forward stew. For more heat, add another ½ teaspoon (1 g) gochugaru at the end and taste before adding more. Gochujang is not a direct replacement: it brings sweetness and a different fermented flavor, so it can change the balance and make the broth thicker.

Use a different tofu texture. Medium-firm tofu stays intact but is easy to bite, while firm tofu gives neater cubes. Soft tofu is also possible, though it will break apart more readily and give the broth a cloudier, softer texture. Add it carefully and avoid stirring once it is in the pot.

Storage and Reheating

Cool leftovers promptly and refrigerate them within 2 hours in a covered container. The stew keeps for 3 to 4 days in the refrigerator. For the best texture, store it in shallow portions so it cools quickly; the tofu may become a little firmer after chilling, and the vegetables will soften more with each reheat. If you plan ahead, you can also refrigerate the broth and cut vegetables separately, then cook the stew close to serving time.

Reheat only the portion you need in a saucepan over medium heat, stirring gently until it is steaming throughout. Add a splash of water if the broth has reduced or become too salty as it sits. For food safety, leftovers should reach 165°F (74°C) when reheated; check the center with a food thermometer. In a microwave, cover the bowl loosely, stir partway through, and check several spots for even heating. Do not repeatedly cool and reheat the entire pot. Freeze leftovers in a freezer-safe container for up to 2 months for best quality; thaw in the refrigerator before reheating, knowing that the tofu and zucchini may be softer.

Frequently Asked Questions

Is doenjang jjigae a soup or a stew?
It is often translated as soybean paste stew. The broth is plentiful enough to spoon over rice, but it is usually served as a savory, substantial dish alongside other foods rather than as a light clear soup. The amount of liquid and vegetables varies between households.

Is doenjang the same as miso?
No. Both are fermented soybean pastes, but doenjang generally has a more robust, earthy, and salty flavor, while many misos are sweeter or milder. Miso works when doenjang is difficult to find, but use it as a substitution rather than expecting the traditional flavor to be identical.

Can I make this without dried anchovies?
Yes. Replace the anchovy-kelp broth with vegetable broth or water, as described in the tips. The finished stew will still be satisfying, but it will have a less savory, less sea-like base. Avoid using regular salted broth without tasting first, since the doenjang already provides plenty of salt.

Why is my stew too salty?
Paste brands differ, and simmering can concentrate the broth. First dilute the pot with a small amount of hot water and taste again. Add extra tofu or unsalted vegetables if you have them. Next time, begin with less doenjang, simmer the stew, and add more only after tasting near the end.

Can I prepare any part ahead?
Yes. The anchovy-kelp broth can be made up to 3 days ahead and refrigerated in a covered container. You can also chop the vegetables a day ahead and keep them refrigerated, though cut potato is best held submerged in cold water and drained before cooking. Add tofu and simmer the stew shortly before serving for the best texture.

What can I use instead of kelp?
If you cannot find dried kelp, make the broth with anchovies alone, or use vegetable broth. The stew will still work, but kelp contributes a gentle savory depth. Avoid adding a large piece of nori as a direct substitute; it can soften quickly and give the broth a different flavor and texture.
