This vegan miso soup is a comforting and nutritious dish that is perfect for any time of the year. It's quick to prepare and packed with flavors, making it an excellent choice for a light meal or a starter. The combination of miso paste, tofu, and mushrooms creates a rich and savory broth that is both satisfying and healthy.
If you are not familiar with miso paste, it is a traditional Japanese seasoning made from fermented soybeans. It can be found in the international or Asian section of most supermarkets. Tofu is another ingredient that might not be common in every household; it is a versatile plant-based protein that can be found in the refrigerated section. Shiitake mushrooms add a unique umami flavor to the soup, but if they are not available, button mushrooms can be used as a substitute.

Ingredients for Vegan Miso Soup Recipe
Water: The base of the soup, used to create the broth.
Tofu: Provides protein and a soft texture to the soup.
Miso paste: Adds a deep, savory flavor to the broth.
Green onions: Adds a fresh, mild onion flavor and a pop of color.
Shiitake mushrooms: Contributes a rich, umami flavor to the soup.
Technique Tip for This Recipe
When preparing miso paste, it's crucial to dissolve it in a small amount of hot water before adding it to the soup. This ensures that the miso is evenly distributed and prevents clumping. Additionally, avoid boiling the soup after adding the miso as high heat can destroy its delicate flavors and beneficial probiotics.

How to Store or Freeze This Soup
Allow the miso soup to cool to room temperature before storing. This helps prevent condensation, which can dilute the soup and alter its flavor.
Transfer the cooled soup into an airtight container. Glass containers are ideal as they do not absorb odors and flavors, but BPA-free plastic containers work well too.
Store the container in the refrigerator. The vegan miso soup will stay fresh for up to 3-4 days.
For longer storage, consider freezing the soup. Pour the cooled soup into freezer-safe containers or heavy-duty freezer bags. Leave some space at the top of the container or bag to allow for expansion as the soup freezes.
Label the containers with the date to keep track of freshness. Frozen miso soup can be stored for up to 2 months.
When ready to enjoy, thaw the soup in the refrigerator overnight. Reheat gently on the stovetop over low heat, stirring occasionally. Avoid boiling the soup as it can alter the flavor of the miso paste and the texture of the tofu.
If the soup appears too thick after reheating, add a small amount of water or vegetable broth to reach the desired consistency.
For best results, add fresh green onions after reheating to enhance the flavor and provide a fresh, crisp texture.
How to Reheat Leftovers
Gently reheat the vegan miso soup on the stovetop over medium-low heat. Stir occasionally to ensure even heating and prevent the tofu from breaking apart. Avoid boiling to preserve the delicate flavors of the miso paste.
Use a microwave-safe bowl to reheat the soup in the microwave. Cover the bowl with a microwave-safe lid or plate to prevent splatters. Heat on medium power in 1-minute intervals, stirring in between, until the soup is heated through.
If you have a steamer, place the vegan miso soup in a heatproof bowl and steam it gently. This method helps maintain the texture of the tofu and mushrooms while evenly reheating the soup.
For a quick and even reheating, use a double boiler. Place the soup in the top part of the double boiler and gently heat over simmering water. This method ensures that the soup heats evenly without direct contact with the heat source, preserving the integrity of the miso paste and other ingredients.
If you have an immersion blender, you can use it to gently stir the soup while reheating on the stovetop. This helps distribute the heat evenly and prevents the tofu and mushrooms from settling at the bottom.
