What Is Miso Soup?

Miso soup is a traditional Japanese soup made from dashi broth and miso paste, often enhanced with tofu, seaweed, and green onions. Miso itself is a fermented paste typically made from soybeans, salt, and koji culture. Depending on the variety, it can be mild and sweet or bold and deeply savory.

For this gluten-free version, we choose a certified gluten-free miso paste, typically made from soybeans and rice instead of barley.

Ingredients for Easy Gluten-Free Miso Soup

• 4 cups water or gluten-free vegetable broth
• 2 tablespoons gluten-free white or yellow miso paste
• ½ cup firm tofu, cut into small cubes
• 1 tablespoon dried wakame seaweed
• 1 teaspoon grated fresh ginger
• 1 small garlic clove, minced (optional)
• 1 teaspoon gluten-free tamari (optional, for extra depth)
• 2 green onions, thinly sliced
• Sesame seeds, for garnish (optional)

Instructions

1. Heat water or gluten-free broth in a medium saucepan over medium heat until warm but not boiling.
2. Add dried wakame seaweed and allow it to rehydrate for 2–3 minutes.
3. Add tofu cubes, grated ginger, and minced garlic. Simmer gently for 3–4 minutes.
4. Lower the heat. Place miso paste in a small bowl and whisk with a few tablespoons of the hot broth until smooth.
5. Stir the dissolved miso back into the soup. Do not boil, as high heat can destroy miso’s beneficial probiotics.
6. Add gluten-free tamari if using, then taste and adjust seasoning.
7. Remove from heat and garnish with sliced green onions and sesame seeds. Serve immediately.

Tips for the Best Gluten-Free Miso Soup

• Never boil miso after adding it—gentle heat preserves flavor and nutrients.

• Rehydrate wakame separately if you want precise texture control.
• Add vegetables like mushrooms or spinach for extra nutrition.
