I would say that Nuoc cham is an ‘all-rounder’ type dipping sauce. It’s sweet, salty, sour and spicy at the same time, so it goes with pretty much anything. The first time I had this dipping sauce was in Vietnam and I think it was just on the table to have with rice paper rolls, pork, noodles and herbs. I think my favourite combo was dipping crispy pork into it.
Dipping sauce can help to finish a dish and I think it’s a great addition to any dinner table where you’re serving lots of different dishes. It obviously goes great with other Vietnamese dishes but I find it works with a lot of Southeast Asian style meats, veg and dry noodles.. anything that needs a little extra zing to it.
Ingredient Notes
Fish sauce: Fish sauce is the backbone of nuoc cham. The recipe gives a range of 2 to 3 tablespoons because fish sauce varies a lot in saltiness and intensity between brands. Add it gradually, tasting as you go. Avoid very cheap brands as they can have a harsh, metallic edge.
Palm sugar: Palm sugar gives the sauce a rounder, more caramel-like sweetness than white sugar. It’s sold in solid discs or blocks that you grate before use. Find it at Asian grocery stores and most supermarkets. Light brown sugar is a workable substitute if you can’t find palm sugar, though the flavour will be slightly different. Don’t use white sugar as it makes the sauce taste sharper and less rounded.
Rice vinegar: The rice vinegar is added to taste at the end and serves a different purpose to the lime juice. Where lime adds a sharp, citrusy acidity, rice vinegar adds a softer, milder sourness that rounds the sauce out. Start with a small splash and add more if you feel the sauce needs more depth in the sour note without sharpening the lime flavour further.

Chef Tips
Add fish sauce gradually and taste as you go
Fish sauce brands vary considerably in salinity and intensity. Start with 2 tablespoons, taste, then add more in small increments. You’re looking for a sauce that is clearly salty but not overwhelming, with the sweet, sour and spicy notes all coming through alongside it. If you go too far with the fish sauce, a little extra lime juice and palm sugar can bring it back.
Make it ahead and let it sit
Nuoc cham tastes noticeably better after it’s had 15 to 30 minutes to sit. The garlic and chilli infuse into the liquid and the palm sugar fully dissolves and integrates. If you make it and serve it immediately it can taste slightly sharp. Make it while you’re prepping everything else and it’ll be ready by the time you sit down. It keeps getting better over the first day in the fridge.
Storage
Store in an airtight jar in the fridge for up to 2 weeks. The garlic will mellow over time and the flavours continue to develop. Stir before serving as the palm sugar can settle at the bottom. The sauce can also be frozen in small portions for up to 3 months. Thaw in the fridge overnight and stir well before using.
FAQs
What do I serve nuoc cham with? It’s the classic dipping sauce for rice paper rolls and Vietnamese spring rolls, but I use it far more broadly than that. It works with grilled chicken, pork belly, cold noodle dishes, steamed dumplings and any Southeast Asian dish that wants a bright, sharp counterpoint. A bowl on the table alongside a spread of dishes rarely goes to waste.
Can I make it less spicy? Yes. Reduce the chilli or leave it out entirely for a mild version. Alternatively, add the chilli whole rather than chopped so it infuses gently without releasing full heat. You can also serve the chilli on the side so everyone can adjust their own bowl. The sauce works well without any chilli at all if you need it heat-free.
