Easy & Tasty Natto Tare Sauce Recipe

At breakfast, I often eat a bowl of rice with natto (fermented soybeans), so in the fridge of my house, there are always some natto packs stored.

The Japanese natto pack usually comes with small packets of tare sauce and karashi mustard, but the amount of the accompanying sauce is little.

Today, I thought I wanted to make a bowl of natto rice soupy or “Tsuyudaku (汁だく)”, so I wanted some extra natto sauce.

Easy & Tasty Natto Tare Sauce Recipe

Doing some online research on how to make natto tare sauce, I found a very easy but reputable recipe, so based on its directions, I decided to make my own natto sauce. 

All I prepared for the recipe are soy sauce, mirin, water, and dashi granules. Following instructions, I actually made the natto tare sauce, so here let me share the process for you.


 First, combine one part mirin, two parts soy sauce, and three parts water in a small bowl

Then, add a pinch of dashi granules and transfer the bowl to the microwave oven.

Lastly, microwave the bowl at 500 watts for 20 seconds, give the sauce a stir, and it is ready to use.

Season natto with the prepared tare sauce and enjoy Tsuyudaku Natto Gohan (rice)!

    Hi! Your blog is so detailed and easy to read! Could you please do an article on the different brands and types of Natto in Japan, focusing on the ones that are non-GMO soybeans and high quality, healthy ingredients? So many Japanese products use poor quality beans, a lot of MSG, etc.. We have to be careful to choose the companies that actually care to make healthy products and not just profits. Thanks!
