Step 1: Making the Fish-Less Fish Sauce

• 1/3 cup tamari or soy sauce
• 1/2 cup vegetarian flavored oyster sauce (a.k.a. mushroom-oyster sauce)*
• 2 tsp rice wine vinegar
• 1/4 cup fermented black beans, made into a paste
• 2 tbsp Shinshu miso (yellow miso)


Blend everything together and store in a sealable jar. This sauce will keep for several weeks in the refrigerator.

*Note: The vegetarian oyster sauce can be omitted, if desired — which of course will lead to a thinner sauce.

Substitute 1:1 for regular fish sauce, or to taste. Just note that this sauce is darker then a “typical” fish sauce, which will affect the color of whatever you are making.

Chef's Notes

For a thinner and slightly more fishy-fishless fish sauce, this recipe for Fish-Less Fish Sauce is also really good. Besides the ingredients used, the other difference is that this fish-less sauce is cooked and it does not keep quite as long as the one made with the fermented beans.

    The fermented black bean paste can be found at most Asian Grocery stores (or online of course). They are quite cheap and a little goes along way. Cheers, Dawn

    Hi Jacinth. Thank you for your engagement here! This sauce can be used anywhere that regular fish sauce is called for. It adds a depth and complexity of flavor. I use it in stir fry dishes as well as curries and when making kimchi.

    Hi Sandra--thanks for writing. I get most of my supplies for this vegan fish sauce at HMart (Asian grocery chain). However, during these times, Amazon will work well. I do not purchase any specific brand, getting the product is my goal. This fish sauce will be delicious in a kimchi. Thanks for writing, hope this helps. -Char
