What’s in Miso Soup?

Miso – Miso is a paste made from soybeans and traditionally used in Japanese cooking. It comes in white or red miso. The red miso has a deeper and saltier flavor and is better for soups and braises.

Tofu – This high protein ingredient is made from soybeans, and typically pressed into blocks. Purchase firm or extra firm tofu for this recipe. Softer tofu will fall apart under the high heat of the Instant Pot.

Nori – Nori is a dried seaweed that is normally sold in sheets. It can be found in most Asian markets. Can’t find nori? Then dashi, a fish soup base, is a simple replacement. Both nori and dashi will accentuate the umami flavor of the broth.

Variations – Add cooked shredded or diced chicken to the soup. Have some pasta or vermicelli noodles ready for spooning into the bowls of soup.

Shiitake Mushrooms – These brown-capped mushrooms are packed full of nutrients. Buy firm and unblemished mushrooms. To clean wipe with a paper towel. White button mushrooms are also good options.

Leftover Miso Soup

  • Leftover miso soup will keep in the refrigerator for 2-3 days. It may be best to refrigerate the tofu and mushrooms separately from the broth.
  • Reheat on the stove, but do not allow it to come to a boil. This will ruin the flavor and cause a loss of nutrients.
