Learn how to make miso soup at home! Brimming with savory, umami flavor, this easy recipe is a delicious side dish, starter, or meal on its own.

Miso soup

Raise your hand if you love miso soup! Same. The cloudy broth is warming, nourishing, and deeply flavorful. On a cold, gray winter day, there’s nothing I crave more. It clears my head and warms me up from the inside out.

For years, I only ate miso soup at Japanese restaurants. But after Jack and I traveled to Japan for the first time, we got curious about Japanese cooking at home. We cooked soba noodles, we made matcha, and we decided to try a miso soup recipe. I don’t know what I was expecting, but I certainly didn’t imagine the process to be so simple. We had steaming bowls of miso soup on the table in under 20 minutes!

Now, this miso soup recipe is a staple in our house. It has a rich, savory, umami flavor, and it’s brimming with chewy seaweed, crisp scallions, and soft tofu. Serve it as a starter or a side dish with your favorite Japanese food, or enjoy it as a meal on its own.

Miso Soup Recipe Ingredients

The first step in any miso soup recipe is making dashi. Unlike meat or vegetable soup stocks, this Japanese broth takes minutes to make. In traditional miso soup, the dashi is made with a mix of dried bonito flakes and dried kombu kelp. To keep my recipe vegetarian, I skip the bonito flakes. On its own, the kombu adds plenty of umami flavor to the base of this soup.

Here’s what else you’ll need to make this recipe:

  • Miso paste – You’ll find this fermented soybean paste in the refrigerated section of Asian markets and most grocery stores. For this recipe, look for white miso paste. Because it’s fermented for less time than darker types of miso, such as red miso, it has a milder, sweeter flavor that’s delicious in this simple soup.
  • Silken tofu – I like to use extra-firm tofu when I’m baking tofu, but in this miso soup recipe, silken tofu is a must. With its super-smooth texture, it practically melts into the savory soup.
  • Wakame – Find this dried seaweed in an Asian market, the Asian section of your grocery store, or online. 3 tablespoons might not seem like much for a whole pot of soup, but don’t be deceived. Soak the dried wakame in a little warm water, and it’ll expand like crazy!
  • Scallions – They add a nice crunch and sweet, oniony flavor to the soup.
  • Tamari – For serving! Add a drop at a time until your soup has a well-balanced savory flavor.

How to Make Miso Soup

This miso soup recipe is super simple to make! Here’s what you need to do:

First, make the dashi. Rinse the kombu, place it in a medium pot with the water, and gently simmer over low heat. Careful not to let it boil! If you do, the kombu flavor will become bitter. After 10 minutes, remove and discard the kombu.

Dried wakame seaweed

Meanwhile, rehydrate the wakame. Place it in a medium bowl, and cover it with warm water. Set it aside for 5 minutes. You won’t believe how much it grows!

Next, make the miso slurry. Ladle some of the hot dashi into a small bowl, add the miso paste, and whisk until smooth. This step is crucial for making a smooth, well-combined miso soup. If you skip it, and add the miso directly to the pot, your soup will be lumpy.

Finally, add the miso mixture to the remaining dashi. Drain the wakame and add it to the soup, along with the green onions and tofu. Simmer the soup over very low heat for 1 to 2 minutes, just to warm it through. Again, don’t let it boil! Because miso is a fermented food, it’s teeming with probiotics. Boiling miso kills these beneficial bacteria, so you’ll miss out on some of its health benefits.

When the soup is warm, enjoy! I like to serve it with tamari to taste.

Miso Soup Serving Suggestions

Serve this miso soup recipe as a starter, side dish, or meal on its own. When I’m eating it as a main dish, I serve it with cooked rice or soba noodles. If I want to make the soup even heartier, I add extra veggies. Japanese turnips, shiitake mushrooms, radishes, carrots, kabocha squash, and greens like spinach or bok choy all work well here. Add them to the dashi and simmer until tender before stirring in the miso slurry.

If I’m serving this miso soup as a starter or side dish, I pair it with other Japanese-inspired recipes like tamago kake gohan or okonomiyaki. Jack and I also love eating it with vegan sushishiitake maki or avocado mango sushi for a fun, at-home sushi night!

Ingredients

  • 1 (3-inch) piece of kombu
  • 4 cups water
  • 3 tablespoons wakame dried seaweed
  • ¼ cup white miso paste
  • cup chopped scallions
  • 6 ounces silken tofu, cubed
  • tamari, to taste

Instructions

  • Gently rinse the kombu piece. Place it in a medium pot with the water and gently simmer for 10 minutes. Don’t let it boil, or the kombu flavor will turn bitter.
  • Soak the wakame in a small bowl of warm water for at least 5 minutes to rehydrate.
  • Remove the kombu from the soup. In a small bowl, stir the miso paste together with some of the hot broth until the mixture is smooth, then stir it back into the soup.
  • Drain the wakame and add it to the soup pot along with the scallions and tofu. Simmer over very low heat for 1 to 2 minutes. Season, to taste, with tamari.

    This was good but I wonder if it would be better to put the wakame in at the beginning and let it rehydrate alongside the kombu. That way you don’t have to discard any yummy nutrient-dense water and it also might soften the wakame more. Thoughts?

      Hi Stephanie, I think that would work well!

      Me too! I couldn’t find the wakame at my local Asian market but adding mushrooms perked things up.

    does anyone know how many calories at in one serving

    • Nessie
      01.02.2023

      1.5 oz of silken tofu have about 30 kcal, and one TBS of miso paste has about 35. The wakame and spring onions hardly have any, so one serving comes out to about 70 kcal.

    I learned how to make this in Japan, and you pretty much have re-created the traditional way I learned, with one exception. You don’t include Katsuoboshi (dried bonito flakes). This should be added to the dashi after the kombu is done and then strained out with the kombu. For the person who didn’t find it salty enough, the bonito will definitely add salt.

      Hi Susan, definitely! I omitted it here only because this is a vegetarian blog.

    What is the best way to store the leftovers and for how long. Thanks

    • Jeanine Donofrio
      01.08.2022

      Hi Eva, I store the leftovers in the fridge in a glass container and reheat on the stove (or in the microwave). It’ll last 4 to 5 days.

        Can it be frozen? Can you freeze tofu?

        • Jeanine Donofrio
          05.23.2022

          hmmm… I haven’t frozen miso soup before so I’m not sure. I think it would be fine? The tofu would be fine, I’m not sure how the seaweed freezes.

    Made this tonight subbing in dashi packet and mushroom soy sauce for the kombu and tamari. I also added some sliced white mushrooms for more substance as this is my main meal for dinner. Delish! Takk fra Norge.

    Actually, I learned from Japanese that you cook everything like a normal soup (with boiling) then turn off the heat then add miso at the end, little by little, to make sure miso dissolve properly, no need to stir it up separately. Miso with tofu and Wakame is my favorite and I make it at home a lot too 🙂

    • Jeanine Donofrio

      Hi Appy, stirring the miso with a little bit of water helps break up any clumps so that it dissolves.

      • C Ellerd
        08.04.2021

        The miso is added at the end off heat to ensure the prebiotic are not lost as high heat destroys them.

    When you say 3 inch (1 piece of kombu) does that mean 3inches by 3inches?

    • Jeanine Donofrio
      02.24.2021

      They’re usually in roughly 1-inch thick strips, so it’ll be more like a 3×1 piece that will expand once it’s in the water.

    This sounds delightful. However, since I don’t have wakame, I’ll add sliced soaked dried shiitakess (with the strained broth) and soba noodles. Also, my tofu is soft, not silken. I’ll live with it.

    I’m really looking forward to making this! One question for you since you say that silken tofu is a must: if I’m not going to the store for a few days, is it better to wait until I can get silken tofu, or do you think my high-protein tofu can sub in at all? I understand that the silken is better for the soup, but if you only had high-protein tofu on hand, would you use it anyway? Or would it be better to make it without any tofu in that case?

      Hi Pam, I would use what you have! It’ll be totally fine.
