Ingredients

• 4 cups Water
• 4 inches Kombu (dried kelp)
• 1 cup Bonito flakes (katsuobushi, optional for non-vegan variant)
• 3 tablespoons Miso paste (white or yellow, keto-friendly with no added sugar)
• 0.5 cup Silken tofu (optional, cut into small cubes)
• 1 teaspoon Wakame (dried edible seaweed)
• 2 tablespoons Green onions (thinly sliced for garnish)

Directions

Step 1

1. Start by preparing the dashi base: Place 4 cups of water and the kombu in a medium saucepan. Allow the kombu to soak in the water for 15-20 minutes for optimal flavor extraction.

Step 2

2. Heat the water with the kombu over medium heat. Just before it starts to boil, remove the kombu to prevent a slimy texture.

Step 3

3. If you’re using bonito flakes, add them to the hot water and simmer gently for about 5 minutes. Strain the broth through a fine-mesh sieve to remove the flakes, leaving a clear dashi broth.

Step 4

4. In a small bowl, scoop out 3 tablespoons of miso paste. Add a few tablespoons of the hot dashi broth to the miso paste and whisk until smooth to create a miso slurry.

Step 5

5. Slowly stir the miso slurry back into the pot of dashi broth over low heat. Be sure not to boil the soup once the miso is added, as boiling can ruin its flavor and nutrients.

Step 6

6. If using wakame, rehydrate it separately in water for 5 minutes, then drain and add it to the soup.

Step 7

7. Optional: Add silken tofu cubes and allow them to warm through for 2-3 minutes without boiling.

Step 8

8. Ladle the soup into bowls and garnish with thinly sliced green onions. Serve immediately.
