Authentic Miso Soup
A comforting, umami-rich Japanese classic that brings the warmth of a traditional kitchen to your home in minutes.
Ingredients
- •4 cups water
- •1 piece (4-inch) dried kombu (kelp)
- •1/2 cup katsuobushi (dried bonito flakes) or 1 tablespoon dashi powder
- •3 tablespoons miso paste (white or red)
- •1/2 block silken tofu, cut into 1/2-inch cubes
- •2 tablespoons thinly sliced green onions
- •1 teaspoon dried wakame seaweed
Instructions
- 1
Place the water and kombu in a medium pot and let it soak for 10 minutes, then bring to a gentle simmer over medium heat.
- 2
Remove the kombu just before the water reaches a boil to prevent bitterness.
- 3
Add the bonito flakes (or dashi powder) to the water, simmer for 1 minute, then strain the broth through a fine-mesh sieve into a clean pot.
- 4
Add the dried wakame to the broth and simmer for 2 minutes until rehydrated.
- 5
Add the cubed silken tofu and heat gently for 1 minute; do not let the soup boil vigorously once the tofu is added.
- 6
Place the miso paste into a small ladle, dip it partially into the hot broth, and whisk with chopsticks or a small whisk until the miso is fully dissolved into the soup.
- 7
Remove from heat immediately, garnish with sliced green onions, and serve hot.
💡 Chef tips
- Never boil the soup after adding the miso paste, as high heat destroys the delicate fermented flavor and nutritional benefits.
- For a vegetarian version, simply omit the bonito flakes and use a kombu-only dashi or a mushroom-based dashi.
- Store leftover miso paste in the refrigerator; it will keep for several months, though the flavor is best when used within a few weeks of opening.
✅ How it should turn out
The finished soup should be a clear, golden-hued broth with tender tofu and soft wakame, offering a savory, salty, and deeply aromatic umami profile.
