This Vietnamese Fish Sauce Recipe (Nước Chấm) is the perfect balance of sweet, salty, tangy, and umami. Ready in just 5 minutes, it pairs beautifully with spring rolls, grilled meats, and noodles!
Okay, let’s talk about that moment when you take a bite of something, and it stops you in your tracks. That was me with nước chấm. I was probably, what—10? 11? And I had just dipped a fresh spring roll into this golden, mysterious sauce. I expected it to taste like soy sauce or something basic. I was wrong.
Instead, it was this magical combination of sweet, salty, tangy, and umami. Like, how does one sauce do all of that at the same time? I remember looking up at my mom, eyes wide, asking, “What is this?” She just laughed and told me, “That’s nước chấm. It goes with everything.” And she was right.
Fast forward to now, and I still feel the same way. Whether I’m dunking crispy egg rolls, drizzling it over a vermicelli bowl, or straight-up drinking it from a spoon (kidding! …kind of), this sauce makes everything better. And the best part? It’s ridiculously easy to make. No cooking. No weird ingredients. Just five minutes and a little taste-testing, and boom—you’ve got the perfect dipping sauce.

- Totally customizable. Want it spicier? Sweeter? Less salty? You’re in control.

Ingredient Notes:
I know, I know—this recipe only has a handful of ingredients. But each one plays a key role. Let’s break it down:
- Water – The base of the sauce. It keeps everything balanced so the fish sauce doesn’t take over.
- Sugar – Adds sweetness and helps round out the bold flavors. Regular white sugar works best here.
- Fresh Lime or Lemon Juice – This is essential. It brings in that bright, citrusy acidity. Lime is more traditional, but honestly, use what you have.
- Fish Sauce – The heart of the recipe. Choose a high-quality brand like Red Boat or Three Crabs. Cheap fish sauce can be overly salty and kind of funky.
- Garlic (Optional but Highly Recommended) – A little minced garlic takes this sauce from good to amazing.
- Bird’s Eye Chili (Optional but Adds a Kick) – If you love heat, this is the move. Thinly sliced Thai chili = chef’s kiss.
Pro Tip: Start with less fish sauce and lime juice than you think you need, then adjust as you go. It’s easier to add more than to fix a sauce that’s too salty or sour!
How To Make Vietnamese Fish Sauce?
Step 1: Dissolve the Sugar
In a bowl, mix 6 tablespoons of water with 2 tablespoons of sugar. If the sugar is being stubborn and not dissolving, warm up a small amount of the water first, stir the sugar in until it melts, then add the rest of the water. Boom. Problem solved.
Step 2: Add the Citrus
Squeeze in 1.5 tablespoons of fresh lime or lemon juice, but don’t just dump it all in at once—taste as you go! The goal is to get it to that perfect lemonade-like balance—tangy but not too sour.
Step 3: Stir in the Fish Sauce
Slowly mix in 2 tablespoons of fish sauce, stirring constantly. At this point, the sauce should be strong—but in a good way. It’s meant to be paired with other foods, so don’t panic if it tastes a little intense straight from the spoon.
Step 4: Add the Extras (Optional but Highly Recommended)
If you’re going for maximum flavor, stir in minced garlic and sliced Thai chili. The garlic infuses into the sauce over time, and the chili adds a little heat. (If you’re sensitive to spice, you can totally skip this—or just add a tiny bit.)

Vietnamese Fish Sauce Recipe (Nuoc Cham)
Ingredients
Base Ingredients:
- 6 tablespoons water
- 2 tablespoons granulated sugar
- 1.5 tablespoons freshly squeezed lime or lemon juice
- 2 tablespoons fish sauce
Optional Ingredients:
- 1 garlic clove finely minced
- 1 Thai bird’s eye chili finely sliced
Instructions
Dissolve the Sugar
- In a medium mixing bowl, combine 6 tablespoons of water with 2 tablespoons of granulated sugar. Stir well until the sugar is fully dissolved. If needed, heat a small portion of the water beforehand to help expedite the dissolving process, then mix it with the remaining water.
Add the Citrus Juice
- Gradually add 1.5 tablespoons of freshly squeezed lime or lemon juice, stirring continuously. Taste as you incorporate the citrus to ensure the desired level of tanginess is achieved. The mixture should have a mild tartness similar to a well-balanced lemonade.
Incorporate the Fish Sauce
- Slowly add 2 tablespoons of fish sauce to the mixture while stirring. Adjust the amount if necessary, depending on personal preference. The sauce should have a slightly bold taste on its own, as it is designed to complement lightly seasoned dishes.
Add Aromatics (Optional but Recommended)
- For additional depth of flavor, stir in minced garlic and finely sliced Thai chili. The garlic will infuse into the sauce over time, enhancing its richness, while the chili adds a subtle heat. If serving to guests, consider offering these as optional add-ins.
Serve and Enjoy
- Once all ingredients are well combined, allow the sauce to sit for at least 5 minutes to let the flavors meld. Serve immediately as a dipping sauce for spring rolls, grilled meats, or vermicelli bowls.
