Ingredients
-
4 cups (960 ml) dashi broth (use kombu + shiitake for vegetarian dashi)
-
4 shiitake mushrooms, thinly sliced
-
2 tablespoons (2.5 g) dried wakame seaweed
-
200 g (7 oz) silken tofu, cubed
-
2 tablespoons (30 ml) soy sauce
-
1 tablespoon (15 ml) mirin
-
1 teaspoon (5 ml) sesame oil (optional, but adds a gentle warmth)
-
1 spring onion (scallion), finely sliced, for garnish
Step‑by‑Step Instructions
-
Warm your dashi. In a medium saucepan, bring the 4 cups of dashi broth to a gentle simmer over medium heat.
-
Cook the shiitake. Add the thinly sliced mushrooms and simmer about 5 minutes, until they’re tender and fragrant.
-
Rehydrate the wakame. Stir in the dried wakame and cook 2–3 minutes—enough to rehydrate it but not turn it soggy.
-
Gently add tofu. Carefully drop in the cubed silken tofu. Let it warm for another 2–3 minutes, being mindful not to break the tofu up.
-
Season the broth. Add soy sauce, mirin, and sesame oil (if using). Taste and adjust—if you prefer it saltier or sweeter, tweak the amounts slightly.
-
Serve. Ladle the soup into bowls and garnish with thinly sliced spring onion. Serve hot.
Cooking Tips & Tricks
-
Use a gentle hand with the tofu. Silken tofu is delicate—stir slowly and use a spoon to ease it into the broth.
-
Mind your dashi. If you’re going vegetarian, use kombu (kelp) plus dried shiitake to build your dashi instead of bonito flakes.
-
Don’t overcook wakame. It’s done when it becomes tender and slightly translucent. Overcooking makes it mushy.
-
Flavor layering beats one big hit. Add your seasonings bit by bit—taste as you go. You can always add more soy sauce or mirin, but you can’t remove it.
-
Warm the bowls. If your serving bowls are cold, warm them briefly (rinse with hot water) so the soup stays nice and hot for longer.
-
Play with garnishes. A tiny drop of chili oil, a few julienned carrot strips, or a sprinkle of toasted sesame seeds can elevate the look and flavor.
A Little Story From My Kitchen
This soup holds a cozy memory for me. A few years ago, after a grueling week of work deadlines, I craved something both restorative and simple. I pulled out my dashi ingredients and whipped up this very suimono. As the steam curled from the pot and the house filled with a gentle mushroom aroma, I felt a quiet calm returning. That evening, my husband and I sat side by side with just rice and this clear soup—and it felt like exactly what I needed. Ever since, whenever I need a little reset (especially after hectic days), I reach for this recipe. I hope it becomes a little comfort ritual for you, too.
What to Serve With Japanese Clear Soup
Because this is a light, clear broth, it pairs beautifully with bolder side dishes or a simple, elegant meal:
-
Serve it before sushi, tempura, or grilled fish to cleanse the palate.
-
Pair with steamed rice or a small bowl of brown rice to make the meal more filling.
-
A side of lightly dressed seaweed salad or cucumber sunomono (vinegared cucumber) complements the flavors.
-
You can even accompany it with grilled or sautéed vegetables or a light protein for a more substantial spread.
How to Store & Reheat
-
Refrigerate promptly. After the soup cools to room temperature (within two hours), cover and refrigerate. It will last about 2–3 days.
-
Store ingredients separately (if possible). If you expect leftovers, consider keeping tofu separate from the broth to preserve texture.
-
Reheat gently. Pour into a pot and warm over low to medium heat. Don’t let it boil vigorously—silken tofu can break apart, and the delicate broth can lose nuance.
-
Taste and adjust. After reheating, you may need a splash more soy sauce or mirin to brighten flavors that mellowed in the fridge.
FAQs
Can I substitute the dashi with something else?
Yes! If you don’t have traditional dashi, you can make a simple vegetarian version: soak kombu (kelp) in water for 30 minutes, then simmer gently. Or—in a pinch—use a mild vegetable broth, though your flavor won’t be as authentically umami.
Can I swap the tofu type?
Silken tofu gives that soft, silky texture which suits clear soup best. Firm tofu can be used, but the mouthfeel changes—it becomes more substantial. Gently warm it instead of letting it simmer.
Is this truly a Japanese vegetarian soup?
If your dashi is plant‑based (kombu + shiitake), yes—it becomes a vegetarian version of a clear Japanese soup. Without bonito or fish-based stock, it aligns with vegetarian and even vegan diets.
How many calories does one serving have?
This recipe yields about 70 kcal per serving (with four servings total). It’s light but satisfying in its own subtle way.
