Last Updated on March 21, 2024 by Share My Kitchen

“Tsuyu” sauce enhances the umami flavor of your Japanese cuisine and is used in noodles and soups. It can come in a huge bottle, but it can be difficult to find it if you are abroad. Fortunately, it’s easy to make, and it’s suitable for vegans!

What is “TSUYU?”

Tsuyu is a sauce that can be used in many Japanese dishes. It is made with a dashi base, and it is full of umami. So this sauce is great for those who lack “umami” in their cooking.

Tsuyu is a delicious combination of sweet and savory. It is made from:

Japanese people don’t make tsuyu from scratch. It is readily available in their supermarkets. However, you can make it from scratch!

Recipes That Use Tsuyu Sauce

Because it has a deeper flavor than just soy sauce, tsuyu may be used in a variety of recipes. These are some of the most popular recipes that make use of tsuyu:

  • Gyuudon: beef rice bowl
  • Oyakodon: chicken and egg rice bowl
  • Devil’s onigiri: rice ball with seaweed, tempura batter and tsuyu
  • Tantanmen ramen: spicy sesame broth with ramen noodles


Tsuyu uses one or more of the following dashi (broth that is used to enhance depth of flavor).

  • Kombu: dried kelp or seaweed
  • Katsuobushi: bonito flakes
  • Awase: combination of kombu and katsuobushi
  • Vegan Awase: combination of kombu and shiitake mushroom

These ingredients are common in Japanese cuisine and should be readily available at Japanese food stores, or perhaps Asian supermarkets.

Typically, dashi is created by boiling or steeping its ingredients in water. But for this tsuyu recipe, water will be replaced and make a concentrated sauce with soy sauce and mirin.

Tsuyu comes in a concentrated form, which makes it easy to store. It can be mixed with water when in use; there is a list with the proportions of tsuyu and water for each use below.

Dried shiitake mushrooms will be used for this recipe because they are readily available in other countries. But you can substitute other types of dried mushrooms if you are unable to find them (but there’s no guarantee how it will affect the taste).

This recipe has only 4 ingredients, and all are suitable for vegetarians or vegans. Enjoy eating!


There are many ways to use tsuyu since it is a concentrated sauce.

  • Pour a small amount directly onto rice – commonly used in donburi rice bowl dishes
  • Pouring onto noodles – 1 part tsuyu: 1 part water
  • Dipping noodles- 1 part tsuyu: 2 parts water
  • For boiling – 1 part tsuyu: 3 to 4 parts water
  • For hot pots or “oden” – 1 part tsuyu: 4 to 6 parts water


You don’t have to use the entire sauce once you’ve made it. It can be kept in a sealed container in the refrigerator for up to one month. And you can make it twice or three times if you use it frequently.


What is Tsuyu?

Tsuyu also known as “mentsuyu” or “hon tsuyu.” This is a sauce most commonly used to make noodles such as thick udon noodles or soba noodles. It can be used to make soup or broth, or as a dip sauce. Also, it has a lot of uses for Japanese stewed dishes like “nikujaga.”

What is the taste of Tsuyu?

It has a similar taste to soy sauce, because it does contain soy sauce. However, it is sweeter and has a more extensive flavor or umami.

Is Tsuyu sauce vegan?

Tsuyu sauce has dashi. Typically, dashi is made with bonito  flakes known as “katsuobushi”. It contains katsuobushi which means that it contains fish. Therefore, this sauce is not suitable for vegans or vegetarians. But don’t worry! This recipe is suitable for vegans because it only uses kombu (kelp) and dried shiitake mushrooms.
