Nam Jim Jaew (Thai Dipping Sauce)

Nam Jim Jaew is a hot, sour and slightly sweet Thai dipping sauce that’s found on practically every street corner in Thailand. It is especially good when accompanying grilled food.

What is Nam Jim Jaew?

Nam Jim is the name given to any number of dipping sauces in Thailand. The one we’re doing today is known as Nam Jim Jaew, hailing from north eastern Thailand, the Isan region. It shares that signature sour and salty flavour characteristic of many Thai nam jim and salads, with an added smoky, toasty note.

The key difference in today’s Thai dipping sauce is the use of dried chilli flakes (prik bon in Thai), instead of fresh chillies. While there’s probably not a single “authentic” nam jim jaew recipe (as each family will have its own slant on it), they will all use chilli flakes for this dipping sauce.

It makes use of everyday ingredients, for the most part. The only thing you might do a Roger Moore at (ya know, raised eyebrow?) is the toasted rice powder. But don’t fret, that’s easily done at home. Let’s take a look at what we need to make Nam Jim Jaew:


We are using a couple of shallots in the recipe, and they are chopped up roughly, so their presence is very obvious. You can use a regular small onion, if you like, white or red is fine.

Red Chilli Flakes

I’ve given you an amount that will produce a little heat, but not too much. Nam jim jaew isn’t meant to be a super hot dip, but if you want it to be so, feel free to up the flakes or use spicy chilli flakes.

Traditionally, the red chilli flakes would be homemade. Chillies would be toasted over open flames, then pounded into flakes. But the modern cook will just use shop bought chilli flakes for nam jim jaew.

The Herb

What herb you use is a matter of preference. The choice is usually between fresh coriander leaves (cilantro) and spring onions (scallions). Both lend a subtle aroma and flavour to this Thai dipping sauce.

I prefer to use coriander leaves, as spring onions are pretty similar to shallots, aren’t they? I’ve even had nam jim jaew with mint leaves on a couple of occasions in Thailand.

Fish Sauce

Any regular fish sauce will do, Thai or Vietnamese. You should be able to find it in any East or South East Asian store and most certainly online. I have both versions and use them interchangeably.

Lime Juice

Any limes will work for this, apart from kaffir lime. We don’t use kaffir lime juice for cooking as it’s bitter. Whatever lime juice you use, it has to be freshly squeezed.

Palm Sugar

You want to get Thai palm sugar which is not as sweet as its Malay and Indonesian counterparts. If unavailable, your best bet is regular white sugar, not brown sugar, which is too strong in every way.

Toasted Rice Powder

This Thai dipping sauce contains toasted rice powder (khao khua) as one of its ingredients, a clear indication of its Isan origin.

Khao khua adds a gritty texture as well as a smoky and toasty flavour to nam jim jaew. As its potency goes fairly quickly, it’s best to prepare a small amount as you need it.

It also thickens your dipping sauce, so the more you use, the thicker your nam jim. Adjust this accordingly, if you like.

Making Nam Jim Jaew at Home

It’s really, really very easy. Once you have the toasted rice powder ready, it should take you no more than 5 minutes with all the chopping and mixing. This is what we’ll be doing:

  1. Make the toasted rice powder (about 10 minutes).
  2. Chop up the shallots and herb.
  3. Mix everything up and stir to dissolve the palm sugar.

That’s it!

How to Serve it?

It’s perfect with just about anything! Here are some ideas:

  • with grilled or fried food.
  • as a salad dressing (it’s the sauce we use when making larb, in terms of ingredients).
  • use it to drizzle just about anything you want, like boiled eggs, omelettes and potatoes.
  • one of my favourite ways of having it is with rice, an egg and a green salad. Simple meal, but sooo delicious!

How long will it Last?

Nam jim jaew is meant to be eaten fresh. I like to leave it to rest for 5 minutes before serving. This allows the flavour to develop and for it to thicken slightly.

On the odd occasion when it doesn’t get finished in one sitting, I cover it with cling film and keep it in the fridge overnight. In terms of flavour, it’s so much better the next day, and thicker too. But the shallots are not as crunchy.

But I won’t keep it any longer than 24 hours.

And now, shall we get our aprons on?

    10/10 Really really good! Do you have the recipes for any other Thai dipping apart from Prik Nam Pla?

    1. Thanks Sammy, I’m glad you enjoyed it. Let me see if I can do a few more over the next few weeks as they’re all easy recipes.
      In the meantime, you might find something of interest on the Chilli Page, it has various hot sauces and chilli pastes from various cuisines.

  2. Personally it is an irritation when anything isn’t proofread. And. When writings are rerun without being proofread, again, it is enough for me to unsubscribe. Where is the “amount given” for the chili flakes? Oh. That’s right. Chili flakes are only mentioned in the introduction of the recipe while observed in the photos. Have you ever even made this recipe?

    1. All you had to do was tell me I’d left out an ingredient. Missing out on details happens to the best of us, there’s a human behind this blog, not a bot. Did I make the recipe? Well, the answer to that is in the pictures, no?

        Second time I’m making this recipe, meant to tell you the first time about the missing flakes but it slipped my mind. Didn’t stop me from making it though, very obvious from the image how much to use.
        I just wanted to let you know, from a longtime subscriber, after that silly woman’s comment above.
        ps: the recipe’s a winner!

    2. 5 stars
      Ever heard of critical thinking Carol? Chili or chili flakes would be something people would season to their own personal preference anyways. Not everyone can handle spice. Your comment is embarrassing and makes you look like an entitled pompous Karen.

      Thanks for the recipe!!! I followed the recipe to a T but used labuyo (Birds Eye chilies) instead of chili flakes and it still turned out incredible.
