Ingredients (serves 1–2)
- 1 whole fish (e.g. tilapia or sea bass)
- 4 garlic cloves
- 3–4 red chillies
- 2 tablespoons fish sauce
- 2 tablespoons soy sauce
- 2 tablespoons palm sugar
- 1 cup vegetable oil (for frying)
- Fresh coriander, to garnish
- 1 lime (optional)
Shopping for the ingredients
When shopping for Pla Rad Prik, it is important to choose fresh, good-quality produce. The fish should be as fresh as possible to guarantee the best flavour, while the garlic and chillies need to be fresh too so the sauce has plenty of aroma and heat. Palm sugar can be found in Asian supermarkets or ordered online. Be sure to buy a decent fish sauce and soy sauce, as these are crucial to achieving an authentic taste.
Preparing the dish
Preparing Pla Rad Prik begins with cleaning and readying the fish. Scale and gut it carefully, then make two or three shallow cuts on each side so it cooks evenly and the heat reaches right through. Finely chop the garlic and chillies so they spread evenly through the sauce. Get everything else measured out and to hand as well, so the cooking itself runs smoothly from start to finish.
Step-by-step instructions
- Heat the vegetable oil in a large pan or wok over a medium-high heat.
- Carefully lower the prepared fish into the hot oil and fry until golden and crisp, about 8–10 minutes per side. Lift it out and let the excess oil drain on kitchen paper.
- In a separate pan, add a little oil and fry the chopped garlic and chillies until fragrant.
- Stir in the fish sauce, soy sauce and palm sugar, stirring continuously until the sugar has dissolved and the sauce thickens slightly.
- Place the crispy fish on a plate, pour over the warm sauce, garnish with fresh coriander and serve with lime wedges if you like.
Gluten-free / lactose-free version
Pla Rad Prik adapts easily to gluten-free and lactose-free diets. Swap the soy sauce for a gluten-free version so you can enjoy the dish without any gluten. As it contains no dairy in the first place, no further changes are needed for a lactose-free meal. Just take care when choosing your ingredients to avoid any hidden sources of gluten, particularly in bottled sauces.
Tips for vegans and vegetarians
For vegan and vegetarian versions of Pla Rad Prik, replace the fish with tofu or another plant-based protein. Use vegetable stock and soy sauce in place of the fish sauce for the sauce itself. Fry the tofu until it is just as crisp as the fish would be, so you get that ideal contrast of texture. Keep the remaining seasonings the same to preserve the authentic flavour. The same crisp-tofu trick works beautifully in a Pad Pak Bung.
More tips and tricks
To deepen the flavour of Pla Rad Prik even further, try adding ginger and lemongrass to the sauce — they bring extra freshness and depth. You can also tune the heat to your own taste by using more or fewer chillies. Experiment with different types of fish to discover which you like best, much as you would when making a Pla Nung Buai. Varying the kind of sugar you use will give subtly different results too.
Adapting the recipe to your taste
Pla Rad Prik is a versatile dish that is easy to tailor to personal preference. Do you love really spicy food? Add more chillies or reach for hotter varieties. Prefer it less sweet? Cut back on the palm sugar or swap it for a less sugary alternative. The choice of fish matters as well: a milder fish such as tilapia lets the sauce shine, while a more robust fish like sea bass lends the dish an extra layer of character.
Ingredient substitutions
Sometimes certain ingredients are hard to find or simply unavailable, and in those cases there are plenty of substitutions you can lean on. Instead of palm sugar, use brown sugar or honey. For the fish sauce, there are vegetarian alternatives based on soy sauce and seaweed. If fresh coriander is out of reach, parsley or spring onions will do the job. Adjust the heat by choosing different chilli varieties, just as you might tweak a punchy Pla Sam Rod.
Drink pairing ideas
The right drink can lift your enjoyment of Pla Rad Prik even higher. A refreshing white wine such as Riesling or Sauvignon Blanc pairs beautifully with the dish and balances the heat. Thai beers like Singha or Chang are a great match too, complementing the spice nicely. Non-alcoholic options such as Thai iced tea or coconut water also make excellent partners. Experiment with a few different drinks to find your perfect combination.
Serving and presentation ideas
Presentation plays a real part in the pleasure of a dish like this. Serve the Pla Rad Prik on an attractive plate and garnish with fresh coriander and lime wedges. Sides such as jasmine rice or steamed vegetables round the meal out nicely. Use fresh, vibrant colours to please the eye, and you can even arrange the sauce artfully, spooning it evenly over the fish for a glossy finish.
A bit of history
Pla Rad Prik has a long tradition in Thai cooking and is hugely popular with locals and visitors alike. It was originally prepared by fishermen in Thailand’s coastal regions, who would transform their daily catch this way. Over the years it found its way into the cities and into the hearts of countless food lovers. The use of fish sauce and palm sugar reflects the wider influence of Southeast Asian cooking on the dish, a thread it shares with classics like Thot Man Pla.
