Method
Pat the catfish pieces dry with paper towels and set aside. In a small bowl, mix together the minced garlic, sliced shallots, black pepper, and 1 tablespoon of the fish sauce. Rub this mixture over the fish and let it marinate for 10 minutes.
Heat the vegetable oil in a clay pot or heavy-bottomed saucepan over medium heat. Add the sugar and 1/4 cup water, stirring gently until the sugar dissolves. Continue cooking without stirring until the mixture turns a deep amber caramel color, about 5-7 minutes.
Carefully add the remaining fish sauce and coconut water to the caramel. It will bubble vigorously, so stand back. Stir until the caramel dissolves into the liquid.
Add the marinated catfish pieces in a single layer. Bring the sauce to a gentle boil, then reduce to a low simmer.
Cover the pot and braise for 20-25 minutes, occasionally spooning the sauce over the fish, until the fish is tender and the sauce has reduced to a glossy, syrupy consistency.
In the last 5 minutes of cooking, add the green onion lengths and sliced chili if using. Taste and adjust with a little more fish sauce or black pepper if needed.
Remove from heat and let the dish rest for 5 minutes. The sauce will thicken further as it cools slightly.
Serve directly from the clay pot, sprinkled with extra black pepper.
Regional variants
In some southern households a pinch of chili flakes or fresh bird's eye chilies are added for extra heat. A modern variation uses salmon or mackerel instead of catfish.
Cook's notes
- Traditional Vietnamese clay pots (tộ) give the best flavor and texture; a small Dutch oven or heavy saucepan works well as a substitute.
- Use firm-fleshed catfish or snakehead fish for best results. Avoid stirring the fish too much once added to prevent it from breaking apart.
- The caramel should be deep amber but not burnt; if it turns too dark the sauce will taste bitter.
Serve with
Steamed white rice, fresh herbs (cilantro, Thai basil), sliced cucumber, and pickled vegetables.
Make ahead and storage
Can be made up to 2 days ahead and refrigerated; reheat gently on the stovetop with a splash of water to loosen the sauce.
