📋 Ingredients

Here are the ingredients (amounts are in the recipe card below).

Ingredients for wakame seaweed miso soup.
  • Wakame is a type of seaweed and a popular ingredient for miso soup. It’s common to use dried wakame that is available all year round. When rehydrated, it will increase in size by ten times. It has a firm yet elastic texture with a subtle smell of the sea.
  • Tofu is a classic miso soup ingredient that gives the soup a soft texture. Tofu comes in 2 different types – Momen (firm tofu) and Kinu (silken tofu). You can use both of them for miso soup. I use Momen in this recipe.
  • Scallions (or green onions)
  • Miso paste is flavorful, savory, and salty fermented food (soybean paste), an essential seasoning for Japanese cuisine. The darker miso ages longer and tastes less sweet than light-colored miso. White miso paste (shiro miso) is the way to go for a sweet and mild taste (Learn more about what miso paste is).
  • Dashi, a traditional Japanese soup stock, is the key ingredient in infusing broth with savory richness. You can choose from various dashi options such as awase dashi (bonito flakes), niboshi dashi (anchovy), and kombu dashi (find more in What is dashi). I simplify the process in this recipe by using store-bought kombu dashi powder (plant-based dashi) in this recipe.

That’s it! Miso soup is best enjoyed when it’s hot, so serve it immediately!

Helpful Tips

  • Always add miso paste after turning off the heat. If you boil the miso, you will lose the excellent flavor.
  • When adding the miso to your soup, stir gently (try not to break the tofu).
  • It’s easy to add miso paste with a whisk (see below).

Miso Measuring Whisk

This Miso measuring whisk is a MUST tool for making miso soup.

You can easily measure and scoop miso paste. All you need to do is to put this whisk into the miso container and turn it around! Plus, you can put the whisk into the soup directly to dissolve the miso.

I love it so much! I highly recommend having this simple tool if you make miso soup often!

Fresh miso soup is the best, but if you have leftovers, let it cool and keep it in the fridge. Transfer the soup to a glass jar or airtight container and store it in the fridge. It will be good for 2 to 3 days.

I don’t recommend putting it in the freezer because freezing and thawing change the texture of the tofu.

Vegan Adaptable

Kombu dashi powder and vegan dashi.

Is miso soup vegan? No, because miso soup’s essential ingredient is dashi, usually made from fish.

But it’s easy to make it vegan using vegan dashi. You can use kombu dashi powder or make vegan dashi (Shiitake mushroom and kombu seaweed) from scratch. Just replace regular dashi with them, and you will have a vegan miso soup.

Other Seaweed for Miso Soup

Variations of seaweed for miso soup.

There is more seaweed you can add to your miso soup.

  • Tororo kombu is shredded kombu (kelp) after pickling in vinegar and used as a garnish in various Japanese dishes.
  • Aosa is flaky seaweed often used as a topping for yakisoba and takoyaki.
  • Nori is crispy and often used for onigiri rice balls and sushi.
  • Seaweed mix is a mixture of dried seaweed and is often used for seaweed salad.

You can add Tororo kombu, Aosa, and Nori as a topping for miso soup (no need to cook).
