The Best Vegan Fish Sauce Substitute You’ll Ever Make

Traditional fish sauce is known for its umami-packed taste, but it’s not exactly vegan-friendly. Whether you’re vegan, allergic to seafood, or just looking to try something new, this homemade vegan fish sauce substitute is here to bring bold, savory flavors to your dishes—without any fishy business. 🌱

This guide has everything you need to know about crafting your own vegan fish sauce, from the ingredients to expert tips, plus loads of creative ways to use it in your kitchen. Let’s get cooking!

🌟 Why You’ll Love This Recipe

• Packed with Flavor: This substitute brings all the deliciousness of traditional fish sauce, minus the seafood.
• Simple Ingredients: You’ll only need six easy-to-find ingredients—most are probably already in your pantry!
• Super Versatile: Perfect for noodle dishes, stir-fries, soups, and marinades. The possibilities are endless.
• Customizable: Adjust the recipe to suit your taste. Want it punchier or a touch sweeter? You’re in control.
• Vegan and Healthier: All the flavor, none of the guilt—this sauce is plant-based and free from hidden additives.

🧾 Ingredient Notes

Here’s what you’ll need for this delicious, umami-packed fish sauce substitute:

• Soy Sauce: The base of the sauce, adding rich, salty depth. For gluten-free options, swap it for tamari or coconut aminos.
• Miso Paste: A powerhouse of umami. White miso works wonderfully, but feel free to experiment with other varieties like chickpea miso for a soy-free alternative.
• Dried Shiitake Mushrooms: These contribute a savory, earthy flavor. No shiitakes? Dried porcini or wood ear mushrooms work just as well.
• Dried Seaweed: The secret to that “ocean-inspired” flair. Kombu, kelp, or wakame are all great choices.
• Garlic: Adds a sharp, aromatic punch to elevate the overall flavor.
• Water: To pull all these ingredients together into a sauce that’s just the right consistency.

Pro Tip: Use fresh shiitake mushrooms if dried isn’t available—you’ll just need to slice them thinly for the same effect.

📋 Variations to Try

Make this sauce your own with these fun twists:

• Spicy Version: Add a sliced chili or a splash of sriracha for heat.
• Sweet and Savory: Stir in a tablespoon of maple syrup or agave for a touch of sweetness.
• Citrus Zing: Squeeze in some lime or lemon juice for a refreshing, zesty twist.
• Nutty Flavor: Add a teaspoon of toasted sesame oil for a layer of richness.
• Herbal Notes: Grate in some fresh ginger for an aromatic lift.

🔪 Instructions

Step 1

Combine all the ingredients—soy sauce, miso paste, seaweed, dried mushrooms, minced garlic, and water—into a saucepan.

Step 2

Bring the mixture to a boil, then reduce the heat to a gentle simmer. Simmer for about 25 minutes or until the liquid has reduced by half.

Step 3

Once the mixture has cooled slightly, strain it through a fine mesh sieve to remove the solid ingredients, leaving you with a smooth, concentrated sauce.

Step 4

Pour the sauce into an airtight jar or container and store it in the refrigerator. It’s ready to use as a substitute for traditional fish sauce on a one-to-one basis.

💭 Expert Tips for Success

• Simmer Slowly: Cooking the sauce low and slow helps the flavors meld beautifully.
• Balance the Heat: Avoid letting the sauce boil aggressively—it should simmer gently to ensure the flavor develops evenly.
• Boost with Mushroom Powder: Enhance the umami punch by adding a teaspoon of vegan mushroom powder towards the end of cooking.
• Strain Well: For a silky-smooth sauce, don’t skip on straining. Use a fine strainer or cheesecloth for best results.
• Adjust to Your Liking: If the sauce is too thick, simply add a bit of water or veggie broth. Too thin? Simmer for a few more minutes to thicken it up.
