Pla Rad Prik

Pla rad prik — whole fried fish with chili-garlic sauce — is the Thai home classic that restaurant menus under-represent: a crisp-fried whole fish drowned at the table in a sweet-sour chili sauce loaded with garlic and basil. The fish is the fried foundation; the sauce is the dish; the two meet only at serving so the crisp survives.
- **Fry and sauce separately — the crisp depends on the timing.** The fish fries first and holds briefly; the sauce takes 6 minutes and is poured at the table. Reversing the order gives you a soggy fish and a cold sauce.
- **The bridge:** tamarind gives the rounder sour; lime is brighter and sharper — both are correct, different moods. The fish: any whole firm fish works; the scoring must reach the bone so the flesh opens and the heat reaches in.

Pla Rad Prik
Prep: 25 minutes · Cook: 20 minutes · Total: About 45 minutes · Serves 3–4
Ingredients
The fish
- 1 whole sea bass, snapper, or tilapia, 600–700 g, scaled, gutted, scored three times each side
- 1 tsp salt; 3 tbsp cornstarch or rice flour for dusting
- Neutral oil, 3 cm deep, at 180 °C
The sauce
- 3 tbsp neutral oil; 5 cloves garlic, minced
- 4 bird's eye chilies (or 2 large red chilies for color and mildness), sliced
- 1 onion (about 150 g), wedged; 1 tomato (about 100 g), wedged (optional but good)
- 3 tbsp fish sauce (about 45 ml); 3 tbsp tamarind or lime juice (about 45 ml)
- 2 tbsp palm sugar (about 25 g), dissolved with the liquids
- ½ cup (about 120 ml) water or stock; 1 tsp cornstarch
- A handful of Thai basil (about 15 g)
Instructions
- **Fry the fish whole (8–10 minutes).** Salt the fish, dust it lightly in starch, shake off the excess, and slide it into the 180 °C oil. Fry 4–5 minutes a side, turning once carefully, until deep golden and the flesh at the thickest score pulls from the bone easily. Drain upright. Checkpoint — the skin should be blistered gold and audibly crisp, the scores opened like mouths. If the skin sticks to the pan, the oil was too cool or the fish too wet — dry fish, hot oil, patience.
- **Build the sauce (6 minutes).** Sizzle the garlic and chilies in the oil 30 seconds, add the onion and tomato and stir 2 minutes, then the fish sauce, tamarind, sugar, and water. Simmer briefly and thicken lightly — the sauce should coat a spoon but still pour generously. Stir in the basil off the heat. Checkpoint — taste: sour-salty-sweet with real garlic punch and chili heat, slightly thickened. The sauce should be bold enough to season the bland-mild fish flesh completely — build it to the edge of too strong.
- **Pour at the table.** Set the whole crisp fish on a platter, pour the hot sauce over generously (serving some on the side for dousing), and eat immediately, flaking the fish into the sauce. Checkpoint — eating test: crisp skin and flaked white flesh scooped through the sauce — sweet, sour, salty, garlicky, the basil's anise arriving late — with jasmine rice to catch what the fish misses. The first ten minutes are the dish's lifespan; the crisp surrenders to the sauce by design, and the sauced-soft fish is its second act.
Troubleshooting
| Symptom | Cause | Fix |
|---|---|---|
| Fish skin stuck, torn | Wet fish, cool oil | Pat bone-dry; 180 °C; don't rush the turn |
| Sauce too thin, slides off | Under-reduced | Simmer to the coat-the-spoon stage |
| Dish tastes flat | Not enough garlic or sour | Both are structural — build to the edge |
Storage, Make-Ahead & Variations
- The sauce keeps 3 days and revives the next fish; the fried fish is a 10-minute food. Sauce-ahead is the make-ahead. - Variations: fillets instead of whole (lose the drama, keep the dish); the three-flavor (sam ros) version with extra tamarind and fried basil on top. The fusion direction — this sauce over the #23 karaage — is a fish-and-chicken conversation the site endorses.
