Recipe: Thai Crispy Fish Topped with Chili Sauce (Pla Raad Prik)

Typically, Pla Raad Prik uses a whole fish, fried until crispy, and then covered with a sweet spicy sauce made from a few ingredients; garlic, palm sugar and chilies, fish sauce and tamarind paste. It is a very popular dish in Thailand that is often ordered for special occasions but it is really quite an easy dish to prepare at home.

As I do not have a whole fish but only three slices of red snapper fillets in my freezer, I was contemplating whether I should cook this dish. Being a seasoned cook, I was very certain that I have all the ingredients and sure enough… Viola! A new dish was born in Mummy’s Kitchen!

Mummy's Kitchen

Hi! My name is Josephine Go. I blog at in a segment called Mummy’s Kitchen. I love to use fresh and natural ingredients in my cooking to promote healthy eating. Some of my recipes may not be in line with the traditional methods of cooking to the extent that some of the ingredients are different, but hopefully new recipes are being created in my style. I certainly hope that what I do will help guide kitchen first-timers on how to cook their first meal as well as further equip kitchen veterans with new recipes. My loving husband and two wonderful children are my best guinea pigs and critics. They have enjoyed (or endured) the food that has been served to them for all these years. Mind you, I did not know how to cook or ever knew that I could cook till I got married. So there is hope for everyone. If I can cook, you can cook. You will not know how good or talented you are until you put your hand in the plough.

One thought on “Recipe: Thai Crispy Fish Topped with Chili Sauce (Pla Raad Prik)

  1. Nice recipe…If you want a bit more heat but without adding more chilli if you pound the chillies and garlic in a pestle and mortar it will be hotter and when you cook them you will get that lovely chilli and garlic smell that you get on the streets of Thailand. My family just exit the kitchen as it gets in their throats and eyes..poor lambs 🙂
