How to Make Dried Natto Snack using Microwave Oven

“Natto (納豆)” is a well-recognized Japanese superfood packed with nutrients. But despite that, many people can’t eat the fermented soybeans mainly because of their stringy, slimy consistency.

Natto Fermented Soybeans

For those people, there is a recommended way to eat Natto beans. Actually, in Japan, Natto is also available in a dried snack form and the traditional soy snack is called “Hoshi Natto (干し納豆)“.

In recent years, the Japanese soy snack can also be bought online outside of Japan, so you might have already tried it.

Dried Natto Snack Recipe using Microwave Oven

Even if not, and if you can get regular fresh Natto beans around where you live, you can easily make the dried Natto snack using a microwave oven.

Since today I actually made the soy snack following the directions of this recipe from Rakuten, for people who are interested, I will share the making process with photos.

By the way, according to this Japanese site, Nattokinaze contained in Natto beans, which is effective in preventing thrombus formation, is weak to heat.

Therefore when you cook Natto beans with a microwave oven, you couldn’t expect health benefits from Nattokinase. However, even in that case, you can take other nutrients. 

As you can see in the video, the dried Natto snack I introduce today is pleasantly crispy and very savory.

So even if you don’t like ordinary sticky Natto beans, you will definitely like the Natto snack. What is more, it will also be a nice treat for your children. 

(Note that cooking fresh Natto beans with the microwave oven results in generating a strong odor characteristic of Natto)

Instructions 

1 Pour the soy sauce that comes with the Natto pack into the pack
2 Stir the Natto beans lightly with chopsticks 
3 Transfer the beans to a large plate and separate each bean 
4 Microwave the Natto beans at 500 Watts for 4 minutes 
5 Take the cooked beans out from the microwave oven and stir lightly
6 Microwave the Natto beans again at 500 Watts for 1 minute or 2 
7 Dried Natto Beans Enjoy the Natto snack!

    Hi Tomo, this is a great idea and would love to try this. I’m in Canada and make my own natto at home. Microwave ovens vary a lot in their power. How many Watts is your microwave oven? Thanks for sharing on your blog, Cassandra

      Thank you for commenting, Cassandra-san!
      The maximum output of my microwave oven is 1000 watts and I heated the natto beans at 500 watts both times!

    Thanks Tomo. Now I see you mentioned you used 500 watts in your blog. Have you tried adding some potato flour on the outside like commercial hoshi natto?
