Korean Soup Brisbane: Doenjang Jjigae with Tofu Recipe

Doenjang jjigae is a Korean soybean-paste stew, usually simmered with tofu and vegetables in a savoury broth and served hot with rice. This version uses zucchini, potato and mushrooms, with ingredients that are easy to find in Brisbane; proportions and vegetables vary between Korean households.

Ingredients

5 cups (1.2 L) water
1 piece dried kelp (kombu), about 3 by 4 inches (7.5 by 10 cm; approximately 6 g)
1 tablespoon (15 ml) neutral cooking oil
1 small brown onion, about 5 oz (140 g), cut into bite-sized pieces
1 medium zucchini, about 7 oz (200 g), cut into half-moons
1 medium waxy potato, about 7 oz (200 g), peeled and cut into ½-inch (1.25 cm) cubes
3 tablespoons (54 g) Korean doenjang (fermented soybean paste)
1 cup (70 g) sliced shiitake or button mushrooms
7 oz (200 g) firm tofu, cut into ¾-inch (2 cm) cubes
2 garlic cloves (about 2 teaspoons / 6 g), finely chopped
1 spring onion (scallion), about ¾ oz (20 g), thinly sliced
½ teaspoon (1 g) gochugaru (Korean red pepper flakes), optional
¼ teaspoon (1.5 g) fine salt, only if needed after tasting

Instructions

Prepare the vegetables and tofu. Cut the onion, zucchini and potato into even, bite-sized pieces so they cook at a similar pace. Slice the mushrooms, cube the tofu and chop the garlic and spring onion. Having everything ready before the stew simmers makes the later steps quick. This preparation takes about 20 minutes, including gathering the ingredients and rinsing the vegetables.
Make a light kelp broth. Put the water and dried kelp in a medium saucepan. Bring it just to a boil over medium heat, then lower the heat and simmer gently for 10 minutes. Turn off the heat and leave the kelp to steep for 5 minutes. Remove and discard the kelp. Avoid a hard, prolonged boil: it can make kelp broth overly strong or slippery.
Soften the vegetables while the kelp steeps. During the 5-minute steep, warm the oil in a separate heavy pot or Dutch oven over medium heat. Add the onion, zucchini and potato and cook for about 3 minutes, stirring often. The vegetables do not need to brown; this brief start in the pot helps build flavour before the broth goes in.
Simmer the potato. Pour the kelp broth into the pot with the vegetables. Bring it to a steady simmer, then cook uncovered for about 10 minutes. Stir once or twice, making sure the potato pieces are not sticking. They should be nearly tender when pierced with a small knife, but not falling apart; if your cubes are larger than ½ inch, allow a few extra minutes.
Add the doenjang and mushrooms. Put the doenjang in a small bowl, add a ladleful of hot broth and stir until smooth, then pour it back into the pot. This makes it easier to distribute the thick paste evenly. Add the mushrooms and simmer for 5 minutes. Taste a spoonful before adding any salt, because doenjang brands differ in saltiness.
Add tofu and finish the stew. Gently slide in the tofu and sprinkle in the gochugaru, if using. Simmer for 4 minutes, stirring carefully around the tofu so the cubes stay intact. Add the garlic and most of the spring onion for the final minute. Taste and add the optional salt only if the broth needs it. Serve while bubbling hot, topped with the remaining spring onion.

Tips

Choose the right paste. Korean doenjang has a savoury, fermented flavour and a thicker texture than many miso pastes. Look for it at an Asian grocery in Brisbane or in the international section of a larger supermarket. If you cannot find it, use the same amount of red or brown miso; the stew will be milder and sweeter, so taste before adding extra seasoning.
Keep the simmer gentle. A rolling boil can break up tofu and make the vegetables mushy. Once the broth is simmering, reduce the heat enough to keep small bubbles around the edge.
Adjust salt at the end. Doenjang varies by brand, and some pastes are quite salty. Do not add salt at the beginning; taste after the paste has simmered into the broth and season only if necessary.
Cut vegetables to cook evenly. Keep potato cubes close to ½ inch (1.25 cm). If you substitute a slower-cooking vegetable, cut it smaller or add it earlier; delicate greens should go in near the end.

Serving Suggestions

Serve doenjang jjigae straight from the pot in warm bowls, with steamed short-grain rice on the side. Rice is useful for balancing the stew’s concentrated, salty-savoury broth, and diners can spoon a little stew over each mouthful. A simple table of rice, the jjigae and one or two small side dishes makes a satisfying meal without requiring elaborate accompaniments.

For a fuller Korean-style spread, offer kimchi, seasoned bean sprouts or a crisp cucumber side dish. These are optional, and the stew is complete without them. If serving kimchi or another salty side, keep the stew’s seasoning restrained. Put extra sliced spring onion and gochugaru on the table so each person can adjust the freshness and heat in their own bowl.

Variations

Make it more traditional in flavour: If you eat fish, replace the kelp-only broth with a mild dried-anchovy-and-kelp broth. Simmer cleaned dried anchovies with the kelp, then strain them out before using the liquid. This brings a deeper savoury note; keep the doenjang quantity the same at first and adjust after tasting. For a vegetarian or vegan pot, use the kelp broth in this recipe and check that the doenjang contains no ingredients you avoid.

Use the vegetables you have: Korean radish, daikon, napa cabbage or a handful of spinach can stand in for some of the zucchini or mushrooms. Add firm radish with the potato so it has time to soften, cabbage during the last 5 minutes, or spinach during the final minute. In Brisbane, zucchini and common mushrooms are convenient options, but the stew is flexible rather than tied to one fixed vegetable list.

Change the heat or richness: Leave out the gochugaru for a gentler bowl, or add a little more for extra chilli warmth. For a richer version, use a small handful of sliced pork or clams, but cook those ingredients safely before serving and account for their cooking time. The tofu-and-vegetable version here keeps the steps straightforward and lets the doenjang remain the main flavour.

Storage and Reheating

Cool leftovers promptly and refrigerate them within 2 hours of cooking, in a covered, shallow container. The stew keeps for 3–4 days in the refrigerator. Tofu can become a little firmer after chilling, and the vegetables will soften further, but the broth remains useful for a quick meal. If you expect not to finish it within that period, freeze portions in airtight freezer-safe containers for up to 2 months for best quality. Leave a little room at the top because liquid expands as it freezes.

Reheat only the portion you plan to eat, on the stovetop over medium-low heat, stirring gently until steaming throughout. Add a splash of water if the broth has concentrated or the vegetables have absorbed some liquid. For food safety, reheat leftovers to 165°F (74°C), checking with a food thermometer. Thaw frozen portions in the refrigerator before reheating, or warm them from frozen over low heat with a splash of water, allowing extra time and stirring as they loosen. Avoid repeatedly cooling and reheating the whole pot.

Frequently Asked Questions

Is doenjang jjigae a soup or a stew?
It is often described as a Korean stew because it is served with a concentrated broth and substantial pieces of tofu and vegetables. It is also commonly grouped under Korean soups in English-language menus and recipe searches. Either way, serve it hot in a bowl with rice.

Can I make this without kelp?
Yes. Use water, or use a mild vegetable stock in place of the kelp broth. Stock will give the stew a slightly different flavour, so choose one that is not heavily seasoned and taste before adding salt. Kelp adds a quiet savoury quality, but doenjang supplies the main character of the dish.

Can I use soft tofu instead of firm tofu?
Yes, but handle it gently. Soft tofu makes a more delicate stew and is easier to break while stirring, so add it in larger spoonfuls near the end and avoid vigorous mixing. Firm tofu holds its shape better and is the most forgiving choice for this recipe.

Can I prepare the stew ahead?
You can chop the vegetables and store them covered in the refrigerator for up to a day, keeping the tofu chilled in its package until needed. The finished stew can also be made ahead and refrigerated for 3–4 days. Its vegetables will soften on reheating, so for the best texture, cook the potato just until tender rather than letting it fall apart.

How can I tell if the stew is too salty?
Taste the broth after the doenjang has simmered for several minutes. If it is too intense, add a little hot water and taste again; adding more unsalted tofu or vegetables can also spread the seasoning through a larger batch. Avoid trying to fix it with sugar, which changes the flavour without removing salt.
