Making miso soup at home is easier than you think, and once you master it, you can customize it to your taste and enjoy a comforting bowl anytime.

What Is Miso Soup?

Miso soup (味噌汁, miso shiru) is a traditional Japanese soup made primarily from miso paste dissolved in dashi, a savory broth. It typically includes ingredients such as tofu, wakame seaweed, and green onions. The soup is light yet flavorful, often served as a side dish with meals or enjoyed on its own for breakfast, lunch, or dinner. The fermented miso paste provides probiotics and a rich umami taste, making the soup both healthy and delicious.

The Key to Great Miso Soup: Making Dashi from Scratch

The foundation of authentic miso soup is dashi, a Japanese soup stock that brings depth and richness.

How to Make Dashi:

  1. Prepare Kombu (dried kelp): Rinse a piece of kombu and soak it in cold water for about 30 minutes.
  2. Simmer Gently: Heat the water and kombu on low heat but avoid boiling, as boiling can make the broth bitter. After about 10 minutes, remove the kombu.
  3. Add Bonito Flakes: Add dried bonito flakes (katsuobushi) to the hot water and let them steep for a few minutes.
  4. Strain: Remove the bonito flakes by straining the broth, leaving you with clear, flavorful dashi.

If you prefer a vegetarian version, you can skip the bonito flakes and use kombu alone or add dried shiitake mushrooms for extra umami.

Making the Miso Soup Step-by-Step

Ingredients:

– Dashi stock (about 4 cups)

– 2-3 tablespoons miso paste (white, red, or mixed depending on your taste)

– 1/2 cup cubed tofu (firm or silken)

– 1 tablespoon dried wakame seaweed (rehydrated)

– 2 green onions, thinly sliced

Instructions:

  1. Rehydrate Wakame: Soak dried wakame in warm water for 5 minutes until it expands.
  2. Heat Dashi: Bring your homemade dashi to a gentle simmer.
  3. Add Tofu: Add cubed tofu to the dashi and warm through for a few minutes.
  4. Make Miso Slurry: In a small bowl, ladle some hot dashi and whisk in the miso paste until smooth. This prevents lumps in your soup.
  5. Combine: Stir the miso mixture back into the pot. Important: Do not boil the soup after adding miso, as high heat destroys its flavor and beneficial enzymes.
  6. Add Wakame and Green Onions: Stir in the rehydrated wakame and sliced green onions, warming for just a minute or two.
  7. Serve: Pour the soup into bowls and enjoy warm.

Tips for the Perfect Miso Soup

Choosing Miso Paste: White miso is mild and sweet, red miso is stronger and saltier, and mixed miso offers a balance. Experiment to find your favorite.

Tofu Texture: Pressing firm tofu before adding it to the soup removes excess water, making it firmer and less soggy.

Customize Your Soup: Add mushrooms, spinach, daikon radish, or even noodles to make the soup heartier and seasonal.

Avoid Boiling: Always add miso paste at the end and heat gently to preserve its flavor and probiotics.

Use Fresh Ingredients: Fresh green onions and good-quality seaweed enhance the flavor and texture.
