Vegan Fish Sauce Recipe Made Easy and Delicious

Updated On: September 30, 2025

For many who embrace plant-based diets, finding vegan substitutes for beloved traditional ingredients can be a delightful culinary adventure. Fish sauce, a cornerstone in Southeast Asian cooking, is known for its deep umami flavor that elevates dishes from stir-fries to dipping sauces.

However, conventional fish sauce is made from fermented fish, making it unsuitable for vegans and vegetarians. Thankfully, creating a vegan fish sauce at home is surprisingly simple, affordable, and yields a rich, savory flavor that closely mimics the original.

This recipe uses pantry staples like dried shiitake mushrooms, seaweed, and soy sauce to capture that signature oceanic tang without any animal products. Not only is it a great way to add complexity to your dishes, but it’s also free from preservatives and additives often found in store-bought versions.

Whether you’re cooking up a spicy Thai green curry or a tangy Vietnamese pho broth, this vegan fish sauce will become your go-to secret ingredient for authentic flavor.

Ready to dive into making your own? Let’s explore why this recipe will quickly become a kitchen staple.

Ingredients

Ingredient Quantity Purpose
Dried Shiitake Mushrooms 1/2 cup Provides umami and depth
Dried Wakame or Kombu Seaweed 2 tablespoons Adds ocean-like brininess
Soy Sauce or Tamari (for gluten-free) 1/4 cup Salty base and umami
Water 2 cups For simmering and extraction
Brown Sugar or Coconut Sugar 1 tablespoon Balances saltiness with sweetness
Minced Garlic 1 teaspoon Enhances savory notes
Minced Shallot 1 teaspoon Adds mild sweetness and aroma
Rice Vinegar 1 tablespoon Brings subtle acidity

Equipment

  • Medium saucepan – for simmering ingredients
  • Fine mesh strainer or cheesecloth – to strain the sauce
  • Measuring cups and spoons – for accurate quantities
  • Glass jar or bottle – to store the finished sauce
  • Knife and chopping board – for mincing garlic and shallots
  • Stirring spoon – to mix ingredients

Instructions

  1. Prepare the dried ingredients: Rinse the dried shiitake mushrooms and seaweed under cold water to remove any grit. Soak the mushrooms in 1 cup of warm water for 20 minutes to soften.
  2. Simmer the base: In a medium saucepan, combine the soaked mushrooms (along with their soaking water), the rinsed seaweed, and 1 cup of fresh water. Bring to a gentle simmer over medium heat.
  3. Add aromatics: Stir in the minced garlic and shallots. Let the mixture simmer gently for 20-25 minutes, allowing the flavors to meld and the liquid to reduce slightly.
  4. Strain the liquid: Remove the saucepan from heat. Using a fine mesh strainer or cheesecloth, strain the mixture into a clean bowl or container, pressing gently to extract all the flavorful liquid. Discard the solids.
  5. Season the sauce: Stir in the soy sauce, brown sugar, and rice vinegar. Taste and adjust seasoning as needed; add more sugar if you prefer a sweeter sauce or more soy sauce for saltiness.
  6. Cool and store: Allow the sauce to cool to room temperature before transferring it to a glass jar or bottle. Refrigerate and use within 2 weeks for best flavor.

Tips & Variations

“Experiment with different seaweeds like dulse or nori to vary the flavor profile.”

Use low-sodium soy sauce if you want more control over salt content. You can also substitute tamari for a gluten-free option.

If you want a smokier flavor, try adding a few drops of liquid smoke or a small piece of smoked seaweed during simmering.

For a thicker sauce, simmer a little longer to reduce the liquid further, or blend in a teaspoon of miso paste at the end for an extra umami boost.

To make this recipe soy-free, substitute soy sauce with coconut aminos, though the flavor will be milder.
