This Japanese-style cabbage miso soup combines sweet, tender cabbage and soft tofu in a savory dashi broth, finished with miso and sliced scallions. It is a simple home-style soup that works as a light meal or a warm side, and you can adjust the vegetables and miso to suit what you have.
Ingredients
- 6 cups (1.4 L) water
- 1 teaspoon (4 g) instant dashi granules, or the amount specified on the package for 6 cups (1.4 L) broth
- 4 packed cups (300 g) green cabbage, thinly sliced
- 1 piece (about 1 oz / 30 g) aburaage, Japanese fried tofu pouch, cut into thin strips
- 3 tablespoons (54 g) miso paste, white or awase (a blend of white and red)
- 2 scallions (about 30 g), thinly sliced
- 1 teaspoon (5 ml) neutral oil, only if needed for the pot
Instructions
- Prepare the ingredients. Thinly slice the cabbage so the pieces soften evenly and are easy to eat with a spoon. Cut the aburaage into narrow strips. If it feels oily, place it in a strainer and pour hot water over it, then drain well; this quick rinse removes some surface oil without making the tofu bland. Slice the scallions and keep them aside for serving. Measure the water, dashi granules, and miso.
- Make the dashi broth. Pour the water into a medium saucepan and stir in the dashi granules. Bring it to a gentle simmer over medium-high heat, stirring so the granules dissolve, about 3 minutes. Follow the package quantity if it differs, since dashi brands vary in strength. The broth should taste savory but not heavily salted; the miso will add more saltiness later.
- Simmer the cabbage. Add the sliced cabbage and stir to submerge it. Reduce the heat to maintain a gentle simmer and cook for 8 minutes, stirring once or twice. The cabbage should be tender but still hold its shape. If you prefer it very soft, simmer for another 2 minutes; avoid a hard boil, which can break up the leaves and make the soup less clear.
- Warm the tofu. Add the aburaage strips and simmer for 2 minutes. They will absorb some broth while retaining a pleasantly soft, slightly springy texture. Taste a piece of cabbage to check that it is cooked to your liking. If the soup has reduced more than expected, add a small splash of hot water.
- Dissolve the miso off the heat. Turn off the burner. Put the miso in a small bowl, add about ½ cup (120 ml) of hot broth, and whisk or stir until smooth. Pour this mixture back into the saucepan and stir gently. Taste before adding more: miso varies in saltiness, so add extra paste a teaspoon at a time only if needed. Do not boil the soup after adding the miso, because vigorous boiling can flatten its aroma.
- Serve. Ladle the soup into bowls and scatter the sliced scallions over the top. Serve while hot, with rice or other Japanese-style dishes if desired. If the soup sits before serving, stir it gently so the miso is evenly distributed.
Tips
- Slice cabbage into spoon-friendly pieces. A thin ribbon around ¼ inch (6 mm) wide cooks quickly without disappearing into the broth. Remove any tough central rib from large outer leaves, or slice that rib extra thin. Green cabbage is mild and reliable; napa cabbage also works and becomes softer more quickly, so begin checking it after about 5 minutes.
- Use a little miso first, then adjust. Miso paste differs in saltiness and intensity. White miso is generally mild and slightly sweet, while red miso is more assertive. Awase miso gives a balanced middle ground. If you only have red miso, begin with 2 tablespoons (36 g), taste, and add more gradually.
- Know the tofu options. Aburaage is a thin fried tofu pouch sold refrigerated or frozen in many Japanese and Asian grocery stores. If you cannot find it, use ½ cup (125 g) of cubed firm tofu instead. The result will be less rich and will not have the same chewy, porous texture, but it is still a good soup.
- Keep the broth at a simmer, not a rolling boil. A gentle simmer cooks the cabbage evenly and keeps the tofu intact. Add miso after switching off the heat, and avoid trying to fix an overly salty pot with more miso. A splash of hot water or a little extra unsalted broth is a better correction.
Serving Suggestions
Serve a bowl as part of a Japanese-inspired meal with steamed rice, grilled fish, pan-fried tofu, or a simple cucumber salad. The soup is also a welcome accompaniment to rice balls or a small bowl of noodles when you want a light lunch. Its savory broth and mild cabbage pair well with dishes that are grilled, crisp, or gently seasoned rather than heavily sauced.
For a more filling bowl, add cooked rice to the soup just before serving, or serve rice alongside so it stays separate until you eat. A small dish of pickled vegetables gives the meal a bright, tangy contrast. Offer extra scallions at the table for anyone who wants a fresher onion flavor. Miso soup is usually served hot in a small bowl, but the cabbage and tofu make this version substantial enough to be part of a simple supper.
Variations
Add mushrooms: Add 1 cup (70 g) thinly sliced shiitake or cremini mushrooms with the cabbage. Shiitake gives the broth a deeper, earthy flavor; cremini is a practical grocery-store substitute. Simmer until the mushrooms are tender, usually 6 to 8 minutes, before adding the tofu and miso.
Use a different cabbage: Napa cabbage has a delicate texture and cooks faster than green cabbage. Start with 5 minutes of simmering and add time only as needed. Savoy cabbage also works, though its leaves are more textured. Avoid using a large amount of red cabbage if you want a familiar-looking miso soup, because its color can tint the broth.
Make a kombu-shiitake broth: For a vegetarian broth without instant dashi, soak one 4-inch (10 cm) piece of kombu and 2 dried shiitake mushrooms in 6 cups (1.4 L) cold water for at least 30 minutes, then warm gently until steaming and remove the kombu before the water boils. Simmer the mushrooms until tender, slice them, and return them to the pot. This adds a more pronounced mushroom flavor and requires extra soaking time, so it is best prepared ahead. Check the dashi granules label if you need a vegetarian option; some contain fish.
Add other vegetables: Thinly sliced carrot, daikon, or onion can be simmered with the cabbage. Keep the combined vegetable amount close to 4 to 5 cups (300 to 375 g) so the broth remains balanced. Add firm vegetables such as carrot a few minutes before the cabbage, since they take longer to soften. A small handful of spinach can go in during the last minute.
Storage and Reheating
Cool the soup promptly and refrigerate it within 2 hours of cooking. Store it in a covered container for 3 to 4 days. For the best flavor and texture, keep the soup in one container rather than leaving it at room temperature while serving; return leftovers to the refrigerator as soon as the meal is finished. The cabbage will soften further as it sits, and the miso flavor may become less vivid.
Reheat only the amount you plan to eat in a small saucepan over medium-low heat, stirring gently, until it reaches 165°F (74°C). Do not let it boil hard; once it is steaming throughout, take it off the heat. If the broth tastes muted after storage, stir in a small amount of miso dissolved in hot broth after reheating. You can freeze the soup for up to 2 months, though the cabbage will be softer and tofu may become more porous after thawing. Thaw overnight in the refrigerator and reheat to 165°F (74°C).
Frequently Asked Questions
Can I make cabbage miso soup without dashi?
Yes. Use a vegetarian instant dashi, or make a simple broth by steeping kombu and dried shiitake in water as described in the variations. Plain water works in a pinch, but the finished soup will have less savory depth. Check ingredient labels, because many standard dashi granules contain bonito or other fish.
Which miso is best for cabbage soup?
White miso gives a gentle, slightly sweet result, while red miso tastes stronger and saltier. Awase, a blend of white and red, is a useful all-purpose choice. Because brands differ, start with the quantity in the recipe and adjust only after tasting the finished broth.
Do I have to rinse the aburaage?
No. Rinsing is optional, but it removes some surface oil and gives the broth a cleaner finish. If you like a richer soup, skip the rinse. If the aburaage is frozen, thaw it in the refrigerator first or briefly rinse it with hot water before slicing.
Can I use bagged shredded cabbage?
Yes. Use about 4 packed cups (300 g), and check the cut size. Very fine shreds cook quickly, so start tasting after 4 or 5 minutes rather than automatically simmering for the full 8. Pre-shredded cabbage may also soften faster than freshly sliced wedges.
Can I prepare this soup in advance?
Yes. Cook the cabbage and tofu in the dashi, cool and refrigerate the broth within 2 hours, then add the miso when reheating for a fresher aroma. Alternatively, make the full soup and refrigerate it for up to 3 to 4 days. Reheat leftovers to 165°F (74°C), and avoid repeated cooling and reheating of the whole pot.
