Miso Soup Recipe Without Dashi

IMPORTANT NOTE: This is not a traditional miso soup but rather a more accessible version for US-based home cooks with ingredients that are easy to find in local grocery stores. Traditional miso soup is made with dashi. If you have an Asian market nearby, then you may be able to buy dashi or make it yourself, but this recipe tastes delicious without it! 

When I lived in Japan, I had easy access to dashi, but since moving back to the states, I’ve had difficulty finding it in US grocery stores. So, below is my version of Miso Soup adapted for ingredients readily available in US grocery stores. Plus, this recipe is made easier by making it in the Instant Pot! 

If you have never had Miso Soup, it is a Japanese soup full of healthy, rich, and savory ingredients. Miso is a fermented soybean paste found in most Japanese cuisine. It adds body and texture to meals.

I know you will love making this fresh and flavorful Miso Soup in the Instant Pot once you try it!  This recipe is way better than any soup packet you can buy in a store loaded with sodium and other preservatives.

  • Any mushrooms will work in this recipe– button, crimini, oyster, etc. If you can find other Japanese mushrooms like enoki, maitake, nameko, or shimeji, add them!
  • I use red miso paste but white or brown will work, too! 
  • You can find Nori in the International section of most grocery stores. 
  • Fish sauces add a slight funkiness that replaces the dashi in traditional miso soup. You can omit the fish sauce if you can’t find it.
  • If you can’t find dashi, then make 5 cups worth of broth and use that instead of water in the recipe below.
    • Omit the fish sauce, if you use dashi.


SERVE: You can keep this out for about two hours before it needs to be covered and refrigerated. 

STORE: Store leftovers in an airtight container in the fridge for 2 days.

FREEZE: Once cooled, transfer the miso soup to a freezer-safe container or Ziploc bag. Freeze for 1-2 months.

DEFROST: Defrost at room temperature for 2-3 hours or overnight in the refrigerator.

REHEAT: Reheat in the microwave for 30-60 seconds, or until heated through.

MAKE AHEAD: This soup can be made ahead and kept warm using the “Keep Warm” setting on the Instant Pot for up to one hour.

Is instant miso soup the same as miso paste?

Miso soup is made using ¼ cup of miso paste and a few other ingredients. As mentioned above, miso paste is made of fermented soybeans and can be found in most US grocery stores.

Does miso soup have meat?

Traditional miso soup does not have meat in it. Instead, it is made of tofu, seaweed, mushrooms, miso paste, and green onions.
