Korean Bean Paste Soup (Doenjang Jjigae)

Korean bean paste soup, commonly made as doenjang jjigae, is a savory Korean stew of fermented soybean paste, tofu, vegetables, and a light anchovy-kelp broth. The paste gives the broth deep, salty flavor while potatoes and zucchini make it filling; families vary the vegetables and heat to suit what they have.

Ingredients

5 cups (1.2 L) cold water
6 large dried Korean anchovies, heads and guts removed, about 12 g
1 piece dried kelp (dashima), about 3 by 3 inches (7.5 by 7.5 cm; 5 g)
3 tablespoons (45 g) doenjang, Korean fermented soybean paste, plus more to taste
1 medium potato, about 6 ounces (170 g), peeled and cut into ½-inch (1.25 cm) cubes
½ medium yellow onion, about 2.5 ounces (75 g), cut into bite-size pieces
1 small zucchini, about 7 ounces (200 g), quartered lengthwise and sliced
12 ounces (340 g) firm or medium-firm tofu, cut into ¾-inch (2 cm) cubes
2 garlic cloves (6 g), finely minced
1 Korean green chili, about ⅓ ounce (10 g), thinly sliced; optional
2 scallions, about ¾ ounce (20 g), thinly sliced
1 teaspoon (5 ml) toasted sesame oil, optional, for finishing

Instructions

Prepare the ingredients, about 20 minutes. Remove the heads and dark guts from the dried anchovies if they are still attached; this helps keep the broth from tasting bitter. Cut the potato, onion, zucchini, tofu, and scallions as listed, and mince the garlic. Doenjang can be lumpy, so set a small bowl and spoon beside the stove for mixing it into the hot broth.
Make the quick broth, about 10 minutes. Put the water, anchovies, and kelp in a medium pot. Set it over medium heat. As soon as the water begins to simmer, lift out and discard the kelp; boiling it for a long time can make the broth slippery or overly strong. Simmer the anchovies gently for about 8 minutes, then strain the broth into a heatproof bowl and discard the anchovies. Return the broth to the pot. If using prepared anchovy-kelp stock, use 4½ to 5 cups (1.1 to 1.2 L) and skip this step.
Season the broth and start the firm vegetables. Ladle about ½ cup (120 ml) of hot broth into the small bowl. Stir in the doenjang until mostly smooth, then pour it back into the pot. Add the potato, onion, and garlic. Bring the pot to a steady simmer over medium heat and cook for 5 minutes, stirring once or twice so the paste does not settle on the bottom. Keep the soup at a gentle simmer rather than a hard boil.
Add the zucchini and tofu. Stir in the zucchini and tofu, taking care not to break the tofu into tiny pieces. Simmer for 8 to 10 minutes, until the potato is easily pierced with a fork and the zucchini is tender but still holds its shape. Taste a spoonful of broth. If it needs more depth or salt, dissolve another ½ to 1 tablespoon (7 to 15 g) of doenjang in a little hot broth before adding it; the saltiness varies between pastes.
Finish and serve. Stir in the sliced chili, if using, and most of the scallions. Simmer for 1 minute, then turn off the heat. Add the sesame oil if you like and scatter the remaining scallions over the top. Serve hot, with rice and small side dishes. The soup should taste savory and rounded, not so salty that it needs to be eaten in tiny sips.

Tips

Adjust the paste gradually. Doenjang is a fermented soybean paste, not a standardized seasoning, so its salt level and intensity differ by brand and age. Start with 3 tablespoons, then add more only after the vegetables have simmered and the broth has had time to take on their flavor. If the soup becomes too salty, add a little hot water or unsalted stock.
Use the right heat. A gentle simmer cooks the potato without breaking up the tofu or reducing the broth too quickly. Stir around the bottom of the pot occasionally, particularly after adding doenjang, because thick paste can catch on a hot spot.
Choose a practical stock substitute. Dried anchovies and dashima are traditional, but a mild, unsalted vegetable broth works if they are hard to find. A few dried shiitake mushrooms steeped in hot water can add savory depth. The result will be less oceanic and somewhat earthier than the anchovy-kelp version. Avoid strongly seasoned broth, which can make the finished soup too salty.
Cut the potato evenly. Pieces close to ½ inch cook at a similar pace. Larger chunks may still be firm when the zucchini is ready; if you prefer larger pieces, give the potato and onion a few extra minutes before adding the tofu and zucchini.

Serving Suggestions

Serve doenjang jjigae hot in individual bowls or bring the pot to the table while it is still gently bubbling. Steamed short-grain rice is the classic companion: spoon a little broth and a piece of tofu over each bite, or alternate spoonfuls of rice and soup. The rice softens the soup’s salty, fermented edge and makes a simple bowl feel like a complete meal.

For a fuller Korean-style table, pair the soup with kimchi, seasoned spinach, bean sprouts, or another small banchan. Keep the side dishes fairly light and do not feel obliged to prepare several; rice, soup, and one crunchy or fresh accompaniment are enough. If serving a group, offer sliced chili separately so each person can choose their preferred level of heat.

Variations

Vegetables are easy to change with the season. Mushrooms, napa cabbage, daikon, or a handful of spinach can replace some of the zucchini or onion. Add firm vegetables such as daikon with the potato, while quick-cooking spinach should go in during the final minute. If using mushrooms, slice them and simmer them with the potato so their flavor has time to enter the broth.

For a spicier bowl, add ½ to 1 teaspoon (1 to 2 g) of gochugaru, Korean red pepper flakes, when you add the doenjang. A thinly sliced Korean green chili adds a sharper, fresher heat. If those ingredients are unavailable, a small amount of ordinary red pepper flakes can work, though the flavor will not be identical. Skip the chili entirely for a mild soup.

You can add protein without changing the basic method. A few thin slices of beef can be briefly cooked in the pot before adding the broth, or cleaned clams can be simmered until their shells open and the meat is cooked through. For a meat-free variation, use vegetable broth and add extra tofu or mushrooms. Different households use different combinations, so treat the vegetables as flexible while keeping the doenjang as the defining flavor.

Storage and Reheating

Cool leftovers promptly and refrigerate them within 2 hours, in a covered container. The soup keeps for 3 to 4 days in the refrigerator. The potato may soften and the broth may taste more concentrated after storage, so stir in a splash of water when reheating if needed. For longer storage, freeze portions in freezer-safe containers for up to 2 months; tofu can become a little more porous after freezing, but it remains usable.

Reheat only the portion you plan to eat, in a saucepan over medium-low heat, stirring gently until steaming throughout. Add water or unsalted broth if the soup has thickened, then taste before adding any more doenjang. USDA FSIS guidance is to reheat leftovers to 165°F (74°C); check the center with a food thermometer. Avoid repeatedly cooling and reheating the full pot, since that makes it harder to handle leftovers safely and can overcook the vegetables.

Frequently Asked Questions

Is doenjang jjigae a soup or a stew?
It is often translated as Korean soybean paste soup, but jjigae is generally thicker and more concentrated than a clear soup. This version has enough broth to spoon over rice while still keeping the savory, stew-like character. The amount of liquid varies among cooks and households.

What is doenjang, and can I replace it with miso?
Doenjang is a Korean fermented soybean paste with a robust, earthy, salty flavor. Japanese miso is the closest widely available substitute, but it is usually milder and sweeter, so the finished dish will taste different. Start with the same amount of miso and adjust carefully; avoid adding salt until you have tasted the broth.

Do I have to make anchovy-kelp stock?
No. The quick stock adds a savory background, but the recipe also works with unsalted vegetable broth or water. If using a substitute, begin with the listed amount of doenjang and taste near the end. Bottled or boxed stock can vary in salt, so a heavily seasoned one may need less paste.

Can I make the soup without tofu?
Yes. Leave it out, or replace it with sliced mushrooms, extra zucchini, or another vegetable. If you want a more substantial vegetarian bowl, add more tofu or mushrooms rather than increasing the salt. Add quick-cooking greens near the end so they stay bright and do not turn limp.

Why does my soup taste bitter?
Old or untrimmed dried anchovies can contribute bitterness, and kelp boiled for too long can make the broth unpleasant. Remove the kelp as soon as the water reaches a simmer, and take out the anchovy heads and guts before cooking. Doenjang itself can be strong, so add extra paste in small increments rather than trying to correct the broth all at once.

Can I make it ahead?
You can prepare the vegetables and broth ahead and keep them covered in the refrigerator, then cook the soup when ready to eat. You can also cook the full soup in advance and refrigerate it promptly for up to 3 to 4 days. The vegetables soften as they sit, so for the freshest texture, add the zucchini and tofu shortly before serving.
