This is a classic Vietnamese dipping sauce made from fish sauce, water, vinegar, sugar, garlic, and chili pepper (optional). Sweet, sour, and savory. We use this sauce for everything from spring rolls, to summer rolls, grilled meats, Vietnamese Salad, and noodle dishes. Make a big batch and keep it in the fridge. It's onolicious and always comes in handy.

Why This Recipe Works
We always have a big jar of Nuoc Cham / Nuoc Mam in the fridge! We make a giant jar of this wonderful dipping sauce every month and use it throughout the month.
Nuoc Cham / Nuoc Mam is a classic Vietnamese dipping sauce. You've definitely see it at Vietnamese restaurants. It's usually served on the side in a small bowl. You either pour the sauce over noodle and grilled meat dishes or use it to dip if you ordered Summer Rolls or spring rolls.
Like Teriyaki Sauce or any type of sauce, everyone has their formula or preferred ratio of ingredients for Nuoc Cham / Nuoc Mam. Try this recipe as is, and then feel free to adjust ratios to your preference when you remake it in the future.
The base of Nuoc Cham / Nuoc Mam is fish sauce. That fish sauce is then seasoned with white vinegar, sugar, and lots of minced garlic and Thai chili peppers. You also have to add water to the sauce otherwise it is too potent for dipping.
The resulting sauce is bright and tangy, a little sweet and a little savory. I love it! And I hope you will too ^_^
Nuoc Cham vs Nuoc Mam
Is this dipping sauce called Nuoc Cham or Nuoc Mam? It can be confusing. Let us explain ^_^
At home, we always call this dipping sauce Nuoc Mam.
Nuoc Mam refers to two things:
- This dipping sauce recipe.
- The bottle of fish sauce itself.
So when you say Nuoc Mam, people might not be sure if you're referring to: 1) the dipping sauce or, 2) the actual bottle of fish sauce (which is an ingredient in many other recipes).
Because of this potential confusion, many recipes are titled Nuoc Cham. Nuoc Cham is the general name for Vietnamese dipping sauces. The only issue is that Nuoc Cham can refer to several different types of dipping sauce, so it's not as specific as Nuoc Mam.
So what to do? To make things extra clear, you can always say "Nuoc Mam Dipping Sauce." ^_^

Step by Step Directions
Let's get cooking!
Prepare garlic and chili peppers
Mince the garlic and chili peppers, either by hand or in a food processor. Set aside.
Protip: Because we're mincing so much garlic, we like to use a food processor. Mince it together with the chili peppers. The red color of the peppers combine to beautifully with the garlic.
Dissolve sugar.
In a large mixing bowl, use a whisk to dissolve the sugar in the water.
Add fish sauce and vinegar.
Stir in the fish sauce. Stir in the vinegar.
Add garlic and chili peppers.
Add the minced garlic and chili pepper. Stir to mix evenly.
Spoon and dip.
Spoon into individual dipping bowls. Ready to use for dipping!
FAQs and Tips
This recipe makes a very big portion of the Nuoc Cham / Nuoc Mam (Vietnamese Fish Sauce Dipping Sauce) Recipe. We like to make a lot at once because we cook Vietnamese food quite often at home.
The sauce also keeps for up to two months in refrigerator. Just make sure to store it in a sealed glass container. Then whenever you need some sauce, you can always spoon out a small serve. So easy and convenient.
Oh so many dishes! We use it primarily for:
- Homemade Summer Rolls.
- Spring rolls.
- Rice and rice noodle dishes topped with a variety of grilled meats (like Lemongrass Chicken) and Vietnamese Egg Meatloaf / Cha Trung.
- Vietnamese Salad (same as Vietnamese Chicken Salad / Goi Ga).
Feel free to add thinly julienned carrots to this sauce if you'd like. We like to do this if we have carrots available at home. Adds a nice bit of color and flavor, but is not super necessary.
This ratio of sugar to other ingredients is classic. It may seem like a lot of sugar but it won't taste like it by the time you're done making the sauce. You can reduce the sugar a little but it will change the flavor.
You can replace the white vinegar with fresh lime juice. The lime juice gives a different flavor profile - softer in flavor but also more tangy. Note: if you use lime juice, the dipping sauce will only keep for one week (versus two months when using white vinegar), so make a smaller batch.
