What Is Seaweed Soup Recipe Vegan?

Seaweed soup (or konbu short) is a traditional dish from Japan consisting of a broth made with dried seaweed sheets.

The sheets of seaweed are whole and crunchy. They are usually eaten with chopsticks, but they turn into soft, chewy chips when cooked in broth.

Preparation Methods

Step 1: Cut up your seaweed. To make this recipe, you need 20 dried/raw seaweed pieces. So, cut your 3 sheets of seaweed into 5 pieces each.

Step 2: Prepare the stockpot. Add the water and soy sauce to the stockpot and set aside while you make the actual soup.

Step 3: Heat the stockpot on medium-high heat.

Step 4: Add 1 and 1/2 teaspoons of chopped garlic, 2 inches of fresh ginger, and 3/4 cup of soy sauce.

Step 5: Cook on low heat for about 8-10 minutes or until the garlic and the ginger are soft.
