A quick and easy recipe for Vietnamese Dipping Sauce (Nuoc Cham / Nuoc Mam) made with fish sauce with a balance of sweet, sour and salty flavors.
If you ever had Vietnamese food either at a restaurant, with family or at a friends place, you’ll know exactly what I mean when I say – those little bowls of dipping sauces that come with your spring rolls (both fresh and fried), grilled meats and Bun Cha (Vermicelli Noodle Bowls) are flavor bombs! Those little bowls of liquid gold are what they call Nuoc Cham or Nuoc Mam, which is a Vietnamese dipping sauce made of fish sauce!
If you have never had Vietnamese Fish Sauce Dipping Sauce (Nuoc Cham / Nuoc Mam) before, this a light and refreshing garlicky dipping sauce with a balance of sweet, sour and salty flavors with the use of fish sauce, sugar and fresh lime juice (or vinegar).
Anyone who has tried and loved nuoc cham dipping sauce will probably have a personal preference with how they like it. Some people like it sourer, others like it a little more sweet or salty and some like it super garlicky! I personally like mine slightly on the sweet and sour side with a good balance of garlic but the awesome thing about this sauce is, it is super easy to tweak to your personal preference by just adjusting the fish sauce (the salty), the lime juice/vinegar (the sour) and the sugar (the sweet).
INGREDIENTS VIETNAMESE FISH SAUCE DIPPING SAUCE (NUOC CHAM / NUOC MAM)
For this Vietnamese Fish Sauce Dipping Sauce (Nuoc Cham / Nuoc Mam) recipe, you can find most of the ingredients at a local grocery store with the exception of fish sauce. If you can’t find fish sauce in the ‘International’ aisle of your grocery store, then you can find it at an Asian grocery store or online – but I highly recommend buying it locally, since fish sauce that has been leaked from a broken bottle during shipping is quite potent and smelly.
LIME JUICE vs. VINEGAR
Whenever I make Vietnamese Fish Sauce Dipping Sauce (Nuoc Cham / Nuoc Mam), I personally like to use fresh lime juice because of the additional flavor fresh limes give it. However, most Vietnamese dipping sauces made at restaurants usually use white vinegar or rice vinegar, mostly because it’s a lot cheaper to produce. There is absolutely nothing wrong with using vinegar! From time to time I will also use vinegar when I am out of limes at home as well.
One of the main differences, I noticed between vinegar and fresh lime juice is the sour level and flavor. Vinegar is slightly less sour compared to fresh lime juice, and lime juice has a slight fruity lime flavor which vinegar does not have. Use what you have on hand, or what your personal preference is! 🙂 Use fresh lime juice and not the bottled stuff, there is a big difference in flavor between the two.
SOAK THE GARLIC IN LIME JUICE TO REDUCE THE GARLICKY SPICY BITE
If you have ever eaten anything that has raw garlic in it, you will notice that raw garlic can pack quite a punch. It has a harsher garlic flavor, as well as a spiciness to it. Depending on how much you love garlic, you can actually tone that garlickiness down a notch by soaking it in lime juice for 15 minutes before combining the rest of the ingredients to make the sauce.
I learned this neat trick through Serious Eats – How to Tame Garlic’s Pungent Flavor. Ah, the beauty of food science! 🙂
This is a completely optional step. If you don’t mind the spiciness and sharp bite from raw garlic then there’s no need to soak the garlic in the lime juice beforehand 🙂
I like to use hot water whenever I make Vietnamese Fish Sauce Dipping Sauce (Nuoc Cham / Nuoc Mam) so that it is a lot easier to use hot water to dissolve and melt the sugar granules. I like to add the sugar and hot water into the bowl with the lime juice and garlic after it has mingled for 15 minutes first to remove that sharp spicy garlic bite.
HOW LONG CAN YOU STORE NUOC CHAM / NUOC MAM?
How long you can store this is highly dependent on whether you use vinegar in the sauce. If you are using only fresh lime juice, then I would not keep this for more than a week or two, but is best enjoyed fresh. If there is vinegar in it, you can keep it for about 2 months. Make sure you store it in an airtight jar in the fridge.
DIFFERENT WAYS TO USE NUOC CHAM / NUOC MAM
I like to use this stuff a lot, especially in the summertime so I like to double or triple the batch when I make it. Here are a few things you can serve this with if you have any extra dipping sauce!
- fresh rice spring rolls
- deep fried spring rolls
- any type of Vietnamese/Thai grilled meats
- a lighter alternative to peanut sauce for satay meat skewers
- salad dressing
- vermicelli bowls with fresh veggies and/or grilled meats
- pan fried crispy stuffed crepes (banh xeo)

Vietnamese Fish Sauce Dipping Sauce (Nuoc Cham / Nuoc Mam)
Ingredients
- 1 clove garlic
- 2 tablespoons fresh lime juice (approximately 1 lime, or white vinegar)
- 2 tablespoons + 1 teaspoon sugar
- 6 tablespoons hot water
- 2 tablespoons fish sauce
- carrots (optional, for color)
- 1-2 fresh chili peppers (optional, for a bit of spiciness)
Instructions
- Peel the garlic and finely chop it. Add it to a bowl (or jar if you are making a bigger batch)
- Cut the lime in half and squeeze all the lime juice into the bowl (or jar) with the garlic and let it sit for about 10-15 minutes. The acid from the lime juice will cut the sharp garlic spicy bite.
- Once 10-15 minutes is up, add the sugar into the garlic/lime juice mix and pour in the hot water. Stir everything together until the sugar dissolves completely.
- Once the sugar has dissolved, add in the fish sauce and mix.
- Voila! Nuoc cham is done! It can be stored in the fridge or used right away! 🙂
Notes
- I like my nuoc cham a bit on the sweeter side so that it has a sweet and sour flavor. If you prefer the sauce more sour/tangy, reduce the sugar by ½ tablespoon
- Most restaurants use vinegar instead of fresh lime juice. To get a nuoc mam closer to the restaurant-style ones, use vinegar instead of fresh lime juice. Keep in mind that fresh lime juice is slightly more tangy than vinegar and has a bit more flavor though.
- To reduce the raw bite from fresh garlic, soak the garlic in the lime juice for 10-15 minutes. The acid mellows out the garlic slightly so it has less of a spicy bite.
- This recipe can be doubled, tripled or quadrupled with no issues
- How long you can store this is highly dependent on whether you use vinegar in the sauce. If you are using only fresh lime juice, then I would not keep this for more than a week or two, but is best enjoyed fresh. If there is vinegar in it, you can keep it for about 2 months. Make sure you store it in an airtight jar in the fridge.

I doubled my recipe and only used 3 tbsp fish sauce. I also found it overly sweet, so would reduce the sweetness next time. Otherwise, very tasty.

How long will this last in the fridge you think?

Hi Daniela!
If you use lime juice, I would store it for no longer than 1-2 weeks, but it tastes best if you using it fresh that day. If you are using vinegar, you can probably keep it for up to 2 months in an airtight jar in the fridge.
Hope this helps!
