More about this spicy Thai condiment
Prik means chili, and nam pla means fish sauce in Thai. These two ingredients are what make up the base of this spicy Thai table sauce.
If youโve ever been to Thailand, youโve probably seen it on the table at street food stalls and local Thai restaurants, usually with chili flakes, sugar, and chili vinegar.

Itโs super easy to make at home, and we always keep a jar in the fridge. You can use it with all kinds of Thai dishes, especially stir-fries. I love it most with fried rice and, of course, pad kra pao!
Ingredient notes and substitutes
Scroll down for the recipe card, or keep reading for ingredient tips and step-by-step instructions to make this Thai chili condiment.
- Fresh chili peppers (4) – Fresh Thai chilies are chopped into thin slices. Fresh chilies are a key ingredient for making this spicy Thai sauce. I always use Thai Jinda chilies. Removing the seeds can tone down the heat if needed!
- White sugar (1/2 tbsp) – Stick with plain white sugar; palm or brown sugar will change the flavor.
- Fish sauce (5 tbsp) – The key ingredient for making Thai fish sauce with chili. It adds saltiness and umami and can be found at most Asian grocery stores or Asian markets. I highly recommend getting a high-quality brand like Megachef.
- Garlic (4 cloves)
- Fresh lime juice (1 tsp) – A little brightens up the sauce with a tangy finish.
How to make nam pla prik
Step 1: Thinly slice the fresh chilies and garlic. The thinner, the better, as theyโll release more flavor into the sauce.

Step 2: In a small bowl, mix the fish sauce, lime juice, sugar, sliced chilies, and garlic. Stir for about 30 seconds until the sugar fully dissolves. Taste and adjust if needed, then serve your prik nam pla sauce with Thai food of your choice.
