Is Miso Soup Vegan Friendly or not?
Miso soup is a traditional Japanese soup dish made by dissolving miso paste in a flavorful broth called dashi, which often includes ingredients like bonito flakes, dried sardines, and kelp.
Although it might seem vegan or vegetarian at first glance, most miso soups aren’t because the dashi base usually contains fish-based ingredients such as bonito flakes. Even some miso pastes have seafood in them so you need to be careful to check the ingredients when selecting a miso paste to suit your dietary requirements. You can say the same with miso ramen as well.
To make a vegan-friendly miso soup, you’ll need to choose your miso paste and ingredients carefully. If you want to learn more about authentic Japanese miso soup itself in detail, check out my miso soup 101 post.
In the next section, I’ll show you how to transform a classic miso soup recipe into a delicious plant-based version suitable for both vegetarians and vegans.
How to Make A Miso Soup Vegan Friendly
As discussed earlier, there are three things to consider when converting authentic Japanese miso soup to suit plant-based diet specifications: the dashi stock, miso paste, and ingredients (toppings).
From here, I will explain how to convert each category separately.
Vegan-friendly Dashi Stock
In Japan, what we call basic dashi is a broth made from a mix of dried bonito flakes and kelp, and sometimes dried sardines are added too. However, you can’t use bonito or sardines to make a vegan version.
The following table shows the types of dashi ingredients commonly used in Japan.
Dashi ingredient (Japanese) | What it is (English) | Vegan friendly? |
---|---|---|
Kombu (昆布) | Dried kelp | Yes |
Katsuobushi (鰹節) | Bonito flakes | No |
Niboshi (煮干し) | Soybeans | No |
Shiitake (椎茸) | Dried shiitake mushroom | Yes |
Ago (あご) | Flying fish | No |
Daizu (大豆) | Soy beans | Yes |
So, I’ll use a vegan-friendly dashi in this recipe, made from a combination of kombu (kelp) and dried shiitake mushrooms. This tasty vegan dashi is perfect for our plant-based miso soup.
Miso Paste
Miso paste can be a key condiment in creating flavorful plant-based dishes. Its main ingredients include koji (malted rice), soybeans, and salt, and its main ingredient is rice, beans, or barley, depending on the type of miso paste.
However, avoiding miso with added dashi or other non-vegan ingredients is crucial. Some miso products now have dashi mixed in, which makes preparing miso soup easier, but they aren’t vegan-friendly. So, be careful when choosing your miso to ensure it’s plant-based.
I used a Japanese brand Marukome’s miso paste. They have many types of miso to choose from, but I chose an organic awase miso paste without dashi and no additives. It’s also gluten-free and delicious, it’s one of my favorites. You can find it on Amazon here.
Ingredients & Toppings
Unlike dashi or miso paste, choosing the right ingredients for vegan miso soup is not as complicated. This is because while most miso soups in Japan are not plant-based (because of the dashi), the basic ingredients and toppings are all vegetables or tofu except for specific miso soup variations such as tonjiru (pork miso soup).
Below is a list of common ingredients used in Japanese miso soup:
- Tofu (silken or firm)
- Wakame (seaweed)
- Mushrooms (such as enoki, shiitake, shimeji…etc.)
- Daikon radish
- Onion
- Green onion
- Potato
- Eggplant
- Spinach
- Okra
The ingredients I used in this recipe are listed in the next section.
Ingredients You Will Need
- Dried kombu kelp – Hidaka kelp, a versatile kelp good for soup stock and eating, is one of my recommendations.
- Dried shiitake mushroom – Dried shiitake mushrooms contain concentrated flavor, and when soaked in water, create a tasty broth packed with umami. Fresh shiitake mushrooms don’t work for making dashi.
- Firm tofu – Silken tofu is also fine, but I used firm tofu because it is less likely to break into the soup.
- Shimeji mushroom – Or your favorite local mushrooms.
- Green onion – The white part is used as an ingredient, while the green part is finely sliced and used as a topping.
- Fresh ginger – To enjoy the texture of ginger, use fresh ginger instead of paste. Adding ginger to miso soup not only creates a unique new flavor profile, but it also warms your body making it perfect for cold days.
- Vegan-friendly awase miso – Again, use vegan-friendly miso paste, not miso paste that already contains dashi.
- White sesame seeds – Use as a final topping.

Place the kombu and dried shiitake mushrooms in cold water. Cover and allow to soak for at least 30 minutes. Some people leave it to soak overnight for a more intense flavor.
Place the pot on the stove and heat over a medium setting. Keep an eye on it and remove the kombu and shiitake right before it starts to boil.
Peel and julienne the ginger, then cut the spring onion and tofu into bitesize pieces. Cut the mushrooms according to preference; since I used shimeji mushrooms, I left them whole.
Add the tofu and vegetables to the dashi broth and cook until warmed through.
If using hard vegetables like carrots, burdock root (gobo), or potatoes, cook them in the dashi until softened, and then add softer vegetables. I recommend using extra water/dashi when cooking root vegetables since they will evaporate as you cook.
I also recommend cutting up some of the rehydrated kombu and shiitake mushrooms that you used for dashi and adding them to the soup to make it a zero-waste miso soup!
Once the vegetables are cooked to your liking, turn off the heat. Add the miso paste to a mesh spoon and dip it into the hot broth. Whisk until evenly distributed throughout the soup.
Pour the completed miso soup into serving bowls and sprinkle with your choice of toppings. In this case I added toasted sesame seeds.
Enjoy!

Miso paste, being fermented, has a long shelf life, but when made into soup and mixed with other ingredients, it spoils easily. Don’t leave leftover miso soup out for long; if you must store it, cool it slightly and refrigerate immediately.
It’s best to eat it as soon as you can, preferably within 24 hours. Miso soup should not be left at room temperature (due to bacterial growth) or frozen (due to deteriorating flavor).
Typically, Japanese families prepare miso soup in the morning and consume it by the end of the day. For instance, enjoy it at breakfast or lunch and again with dinner.
Conversely, dashi alone lasts 5-7 days in the fridge or up to a month in the freezer. With dashi on hand, you can quickly make fresh miso soup in under 10 minutes. If you want to make a big batch, make a big batch of dashi rather than make a big portion of miso soup. That way, you can make miso soup on demand easily and enjoy the freshness of the miso’s flavor.
FAQ
Absolutely! You can enjoy a vegan version of miso soup by swapping out the traditional fish-based dashi broth with a plant-based one.
Vegan miso broth uses miso paste, made from fermented soybeans, salt, and sometimes grains like rice or barley. The soup’s dashi base is usually made with dried kelp, dried mushrooms, or both, creating a delicious flavor that is completely plant-based. In this recipe, I combined dried kelp and dried shiitake mushrooms to make the base.
Traditional miso soup in Japan often isn’t vegan since it contains fish-based dashi broth. When in doubt, ask the staff or search for vegan-friendly eateries. On a side note, plant-based dishes in Japan are traditionally called shojin ryori (精進料理) and often have roots in Buddhism.
