Ingredients
• Prep Time: 5 minutesCook Time: 5 minutesMakes 4 servings
• 2 teaspoons dried wakame seaweed
• 4 cups (960 ml) / 1 liter Vegetarian Dashi
• 1 cup / 275 g miso paste
• 12 oz / 350 g firm tofu, cut into ½-inch / 1.25-cm cubes
Instructions
1. Rehydrate the Wakame: Place the dried wakame in a small bowl and cover with lukewarm water. Let it sit for 5-10 minutes until it has fully expanded, then drain any excess water.
2. Warm the Dashi: In a medium pot, gently warm the vegetarian dashi over medium heat until it is hot and steaming, but do not let it come to a full boil.
3. Dissolve the Miso: Place the miso paste in a small bowl. Ladle about ½ cup of the hot dashi into the bowl and whisk until the miso is completely smooth and dissolved. Pour the thinned miso mixture back into the pot and stir gently to combine.
4. Assemble and Serve: Divide the rehydrated wakame and cubed tofu evenly among four serving bowls. Carefully ladle the hot miso broth over the tofu and wakame. Serve immediately.

Pro Tips
• Never boil the soup after adding the miso paste. Boiling can destroy its delicate flavor and kill the beneficial probiotic cultures.
• Experiment with different types of miso! White miso (shiro) is mild and slightly sweet, while red miso (aka) is saltier and more pungent. A mix of both is also delicious.
• Customize your soup with other like sliced scallions, shiitake mushrooms, or a sprinkle of sesame seeds for extra flavor and texture.
FAQ
Q: Is all miso soup vegetarian
A: No, traditional miso soup is often made with dashi containing bonito flakes (fish). This recipe is specifically vegetarian because it uses a plant-based dashi, typically made from kombu (kelp) and shiitake mushrooms, ensuring it is completely free of animal products.
Q: How can I add more protein to this vegetarian miso soup
A: This recipe already provides a good source of plant-based protein from the firm tofu. To increase the protein content further, you can add more tofu, shelled edamame, or even a handful of cooked chickpeas or lentils for a heartier soup.
Q: What can I use instead of tofu in this recipe
A: If you don’t have tofu or prefer an alternative, you can substitute it with other vegetarian ingredients. Sliced shiitake mushrooms, baby bok choy, or leafy greens like spinach (added at the very end) are excellent choices that add flavor and nutrients.
Q: Can I make this vegetarian miso soup ahead of time
A: Miso soup is best enjoyed fresh to preserve the delicate flavor and beneficial probiotics of the miso paste. You can prepare the vegetarian dashi broth ahead of time and store it in the fridge. When ready to serve, simply reheat the dashi, dissolve the miso, and add the fresh tofu and wakame.
Pro Tips
- Never let the soup boil after the miso goes in — the recipe warns against it, and boiling dulls both flavor and aroma.
- Mix the miso with a ladleful of warm broth before adding it to the pot — no clumps, no hunting down stray paste.
- Wakame rehydrates fast, so add it early but don't overdo it — a little blooms into a lot.
- Experiment with different miso varieties, as the recipe suggests: white for sweet and gentle, darker for deeper punch.
Frequently Asked Questions
Which miso should I use?
Any works — the recipe encourages experimenting. Start with white (shiro) for a mild, slightly sweet bowl and go darker when you want intensity.
Is miso soup vegetarian?
Restaurant versions often use fish-based dashi, but this one is built on Vegetarian Dashi, so it's fully vegetarian.
Can I add more vegetables?
Yes — the recipe invites add-ins. Keep them quick-cooking so the soup stays a true ten-minute affair.
How do I store leftovers?
Refrigerate for a day or two and reheat gently below a boil — the tofu and wakame hold up fine, though the miso flavor softens slightly.
