Equipment

  • Instant Pot

Ingredients

  • 1 tablespoon olive oil
  • 1 cup shiitake mushrooms sliced ¼” thick
  • 5 cups water
  • ¼ cup miso paste
  • ¼ cup tofu firm tofu, cut into ½” cubes
  • 1 sheet nori in 1” cubes, dried seaweed
  • 2 green onions sliced ¼” thick
  • ½ teaspoon fish sauce optional

Instructions

  • Heat the Instant Pot using the Saute-Normal function.
  • Add the olive oil and allow it to heat for 30 seconds. Then add the mushrooms and saute, stirring occasionally, for 5 minutes, or until the mushrooms start to turn golden brown.
  • Add the water and miso paste. Whisk until the miso paste has fully dissolved.
  • Add the tofu, nori, green onions, and fish sauce, if using.
  • Secure the lid and heat it using the Pressure Cook-Manual-High Pressure setting for 8 minutes. Ensure the pressure is in the “sealing” position.
  • When the Instant Pot has finished cooking, release the pressure manually by switching the valve to the “venting” position. Be careful-- the vent will steam and may splatter.

Notes

This soup can be made ahead and kept warm using the “Keep Warm” setting on the Instant Pot for up to one hour.
Store any leftover soup in an airtight container in the refrigerator for up to two days.
Important Note: This is not a traditional miso soup, but rather a more accessible version to US home cooks. Traditional miso soup is made using dashi, not water. If you have an Asian market nearby, you may be able to buy dashi or make it yourself but this recipe tastes delicious without it!
Any mushrooms will work in this recipe-- button, crimini, oyster, etc.
I use red miso paste but white or red will work!
Nori can be found in the International section of most grocery stores.
Fish sauces add a slightly funkiness that replaces the dashi in traditional miso soup. If you can’t find fish sauce, you can omit it.
