What is Japanese Clam Miso Soup?

Japanese Clam Miso Soup is a flavorful, briny soup made from dashi stock and miso paste.  Clams, or asari as it is called in Japan, adds a distinct and unique flavor and compliments miso very well.

It’s a traditional Japanese soup that is served in many Japanese restaurants, especially sushi bars, and perfectly compliments Japanese meals.

What are the instruction to make miso soup?

First, de-grit or de-sand clams in salt water for approximately 15-20 minutes.  Then in a large pot, boil water on medium-high heat and add bonito flakes to make the dashi broth.

Next, drain water from the clams and add it to the dashi broth and give it a good stir.  When all clams have opened up (2-3 minutes), reduce the heat to simmer, mix in the miso and scoop into a serving bowl and top with fresh chopped scallions.

What kind miso should I use?

There are 3 main kinds of miso used in Japanese cooking:

  • White Miso Paste –  saltier and light in taste
  • Red Miso Paste – stronger in miso flavor and bold
  • Brown Miso Paste (awese miso) – mix of the 2 and the one we prefer to use.

Why do you soak the clams in water?

To de-grit or de-sand the clams.  Most clams are already de-sanded before being sold, but just in case, it’s good practice to do it at home.

What is dashi stock and how do you make it?

Dashi stock is a very popular broth used in many Japanese recipes.  It is made from bonito flakes and/or kombu seaweed.  When you taste the umami in Japanese cuisine, most likely what you’re tasting is from the dashi stock.

You can also make instant dashi by adding some hondashi into water.

What kind of clams work best in miso soup?

Manila clams, work the best because of the natural umami flavor. But you can also use littleneck clams as well.

Did you have any tips on making this Japanese Clam Miso Soup recipe?

  • Try to buy manila clams that have already been de-gritted/de-sanded to save time.
  • Never boil the miso soup as it will lose its flavor and natural probiotic properties.
  • Use hondashi to make instant dashi.
