This Easy 5-minute vegan fish sauce is my favorite go-to sauce to use in a variety of Vietnamese and Thai dishes. In just 5 minutes and a few simple ingredients, you’ll get a delicious sauce for your favorite dishes. When you see a recipe that calls for ‘fish’ sauce, this is the one that I’m referring to.
The recipe is an aromatic mixture made from simple pantry items and less salty than store-bought brands. This sauce tastes much better the next day after and can be refrigerated for longer shelf life.
5-minute step-by-step Vegan fish sauce:
First, place minced garlic into a mason jar or bowl, then, add in the chili flakes, salt, maple syrup, and lime juice. Slowly add in the hot water and mix until well combined. Let this mixture steep to release its flavor and refrigerate once cooled down.

I LOVE this sauce. The ingredients are simple but the flavor is complex and delightful.
This recipe has been a staple in my cooking for the past year. During the summer it’s nice to make a day before hand. I usually will fry some tofu and then pour this sauce over for a light, tasty and spicy dinner. Add some fresh greens and some rice and it’s beyond perfection!
I can’t wait to try it! I’ve tried to make vegan fish sauce on my own and from other recipes and they always have soy sauce which is too strong and not the taste I was going for. This looks perfect!
I just made it and it’s perfect! Thank you! I love your site and the simplicity of the layout! I am so glad I came across it- Southeast Asian food is my favourite!
Amazing recipe- thanks for sharing!!
If you store it in the fridge – how long will it last?
Hi Rebecca, mine never lasted long since we use it a lot. 🙂 But it’s good for up to 2 months.
Hi Woon Heng,
Is it okay to skip the garlic? Can I substitute with ginger instead? Thank you.
Hi Tamara, you can skip it. If you plan to use garlic, please replace garlic with a teaspoon of ginger juice. Thanks!
Thank you this amazing sauce recipe, I use them over cucumber and chill them for an hour and then have it with a meal or a snack – super way to beat the heat and still eat healthy
Awesome! thanks so much Rags, this is indeed a handy sauce to have. 🙂
Thank you for sharing your delicious recipes! Your red chili oil is a staple in our family. I’m about to make this “fish sauce” but unfortunately I don’t have lime at the moment. Can I use lemon juice instead?
Hey Mara, so glad to hear that and yes, you can. 🙂
I am so glad I have this recipe now. Ever since switching over to a plant-based diet, recipes requiring fish sauce always made me frown. This recipe is delicious. Thank you!
yay, thanks so much Alice. This is really my go-to condiment for a lot of Vietnamese and Thai dishes. 🙂 Thanks so much. Have a beautiful day! Best, WoonHeng
Hi, I just want to thank you for this perfect recipe! It tastes just like the real fish sauce. I’m Vietnamese and have switched to vegetarian diet recently and it’s amazing I’ve found this alternative to fish sauce. Thanks again and wish you all the best.
Hello Hai,
Thanks so much, this means a lot. I actually tested this recipe and let a few of my Vietnamese friends try it out before sharing. 🙂 So glad you liked this recipe. Thanks, WoonHeng
Wonderful sauce! Exactly the flavors I was looking for, fresh, sweet and spicy! I reduced the amount of water to 1/4 cup to have a more concentrated sauce. I love your recipes and this one was another great one!
yay, thanks so much Tahottie. I’m really happy you loved the recipe and make it more concentrated. Thanks for sharing this idea. 🙂 Best, WoonHeng
I admire your blog , it has of lot of information. You just got one perennial visitor of this blog!
I never made this before (and therefore haven’t made any of your recipes that call for it), but I decided to make your pad Thai today and so I made the fish sauce. This was so easy to make and is so good! I can’t believe such simple ingredients wound up tasting so different. Thanks for another great sauce recipe!
Thanks a lot Mina for your wonderful feedback. I am so glad you love this recipe. It’s one of my go-to to a lot of Vietnamese and Thai dishes. I hope you get to try more recipes soon. Happy cooking and have a beautiful day! Best, WoonHeng
