Nước chấm is a staple dipping sauce on tables all across Vietnam and Vietnamese kitchens around the world. A sharp, salty and deeply umami pop of funky flavour and fragrance. It’s so popular not only because it’s delicious, it’s because it’s quick and pairs with just about everything Vietnamese.

Nuoc cham is a condiment I make often - it's such a versatile sauce that it can be enjoyed as a dipping sauce or used as a dressing for salads and cold dishes or as a simple marinade for meats and seafood. If I'm grilling meat in either a Vietnamese, Thai, Laotian, Burmese or Malaysian style, I will invariably use this simple recipe to act as a condiment.

The sauce is a combination of fish sauce, sugar, lime juice, garlic, chilli and water. That covers sweet, sour, salty and spicy - the unmistakeable flavours of Southeast Asia. When I first tried to make it (from an old recipe book) it was very off balance, and I just couldn't get the taste right. I later saw a TV show where an old Vietnamese lady whipped up a batch in what seemed like seconds - I copied her to a tee, and it has been my go-to recipe ever since.

Strictly speaking, nuoc cham is Vietnamese, but I've found it's interchangeable with many other Southeast Asian flavours, especially fresh salads, charred meats and vegetables. You'll find more delicious recipes like this at my Asian Collection and also my Southeast Asian hub.

Why I make this again and again

It's super quick to make - 5-10 minutes is all it takes when you get the hang of it.
It lifts dishes to new heights - simple BBQ chicken (even supermarket rotisserie chicken) is elevated to a flavour extravaganza with a dressing of nuoc cham. It's also an essential for my delicious lemongrass pork chop recipe.
Rice paper rolls are transformed - with a little nuoc cham on the side
A dressing - when poured over a vermicelli bowl, like my Bun Cha Vermicelli salad, it creates a quintessentially Vietnamese meal.

A Few things I've learned

The balance is personal - many people have differing opinions on what's right or wrong. A nuoc cham can be personally adjusted to suit your taste - as long as you're using the key ingredients, you'll be good to adjust as you see fit.
Not to be precious - I used to be such a purist that I would only eat this condiment with Vietnamese food. These days I've chilled out thankfully, and am happy to pair nuoc cham with dishes like Thai Crying Tiger Beef, Malaysian Ayam Goreng or even as a dressing for a simple Green Salad to serve with Asian food. Life's too short!
Make it in manageable portions - you only need a little at a time. This recipe makes plenty for a meal for 6. It keeps well in the fridge for a week and freezes excellently. I will sometimes freeze in ice cube trays if I have a lot leftover.
I don't like lemon juice for this recipe - It just doesn't taste authentic! If you can't get limes, use white vinegar instead (commonly used in Vietnam).

Ingredients and How to

Here's what you'll need to make my version of nuoc cham. To make it is so easy - just whisk together everything below:

Fish sauce - for authenticity use a Vietnamese brand. I like to use 'Three Crabs Fish Sauce' most of the time. It gives that unmistakeable salty, funky umami flavour that is essential.
Lime juice - adds its sour, citrus flavour to counter the salt of the fish sauce. If you can't get limes, use white vinegar.
Sugar - Brings all the salt and sour flavours down a little to sweeten things up. It's an essential step.
Chilli & Garlic - experiment with how much or little heat you like - the garlic brings a little savoury note to the sauce.
Water - essential to dilute the intensity of the flavour for a more fragrant, balanced sauce.

EXTRAS: I have, on occasion added finely chopped cilantro stems too, and other times a little freshly ground black pepper, These are my additions, but still stay within the region's flavour profile.

FAQ

Have a question? Let me know in the comments.

What is the difference between nước chấm and nước mắm?

Nước mắm is Vietnamese fish sauce straight from the bottle. Nuoc cham is the prepared dipping sauce made by combining fish sauce with water, sugar, lime juice, garlic and chilli.

How do I balance nuoc cham?

Taste and adjust as you go. Add fish sauce for salt and umami, lime or vinegar for sourness, sugar for sweetness and water if the flavour is too intense.

Can I make nuoc cham without lime?

Yes. White vinegar is a common alternative and gives the sauce a clean, sharp flavour. I prefer it to lemon juice, which changes the characteristic taste.

How long does nuoc cham keep?

Stored in a clean, airtight container, nuoc cham keeps in the fridge for about one week. The garlic and chilli may become stronger over time, so taste it before serving.

Can nuoc cham be vegetarian or vegan?

Traditional nuoc cham is neither because it contains fish sauce. For a plant-based version, replace it with vegan fish sauce or a light soy-based alternative and adjust the seasoning to taste.
