Easy & Tasty Natto Tare Sauce Recipe

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

The Japanese natto pack mostly comes with sachets of Tare sauce and Karashi yellow mustard, but the amount of the enclosed sauce tends to be small.

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

As a result, I researched how to make natto sauce online and found a super easy yet reputable recipe by chance.

The simplicity instantly made me want to try it, and I decided to make my own based on its directions.


All you need to prepare for this recipe are soy sauce, mirin, water, and dashi powder.

As the variety of dashi used in commercial natto sauce varies depending on the maker, you can use your desired flavor of granules.


Following the instructions, I actually made the Tare sauce and enjoyed a bowl of Tsuyudaku Natto Gohan, as shown above!

And here, for those interested, I will share the process with photos.

    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!

    Thank you for your recipe for tare! In America I can buy nattou, but it sometimes does not contain that packet of tare so I’m glad to know how to make it myself.
