How to make Vegan Fish Sauce! – a plant-based substitute for fish sauce that adds depth and umami flavor to Asian dishes. Gluten-free adaptable.


Units Scale
  • 4 cups water
  • 1/4 cup soy sauce– shoyu, tamari, or Braggs liquid amino acids
  • 1/2 cup dried mushrooms (like dried shiitakes)
  • 1 4 x 8 inch sheet of dried kombu (seaweed) or wakame seaweed
  • 4 garlic cloves, sliced
  • 2 1/2 tablespoons kosher salt
  • optional additions- 1 fat shallot sliced, grilled (charred) onion, roasted garlic, black garlic, small splash rice wine, sherry, or rice vinegar. Smoked Shoyu if you can find it, is a great option for the soy sauce.


  1. Bring all to a low boil and turn down to a simmer in a medium saucepan, uncovered, over medium heat. Simmer on low until reduced by half.  You should have about 2 cups of liquid.
  2. If you have time, let this steep overnight, or up to 24 hours, covered on the counter. Then strain into a bowl and pour into a clean glass bottle or jar.
  3. ***If the liquid is less than 2 cups, add water to make it 2 cups. This will ensure the right amount of saltiness.
  4. Store in the fridge and use as you would fish sauce, one to one.


  1. The Vegan Fish Sauce will keep up to 3-6 months in the fridge. Probably longer. 🙂
  2. Smoked Shoyu adds even more complexity if you can track it down. Grilled or roasted onions, black garlic, or roasted garlic add even more depth. You can get pretty crafty when you start thinking about creating depth and umami, so please, feel free to experiment and play around.
