Ingredients

  • 1 pound catfish steaks (fresh or frozen) (450g)
  • 3 tbsp fish sauce (adjust to taste)
  • tbsp granulated sugar (for the marinade, adjust to taste)
  • ½ tsp salt (adjust to taste)
  • ½ tbsp granulated sugar (for caramelizing; can be substituted with Vietnamese caramel sauce, dark soy sauce, or molasses)
  • 1 tbsp cooking oil
  • 1 tbsp sliced white part of scallion or shallots
  • ½ tbsp peppercorns
  • Boiling water

Instructions

  • If using frozen catfish, defrost and rinse it with water and a bit of ginger to remove any fishy smell. Pat the fish dry with paper towels.
  • Season the catfish with fish sauce, sugar, salt, and sliced scallions. Let it marinate for at least 30 minutes to absorb the flavors.
  • In a heavy-bottomed pot, heat the cooking oil and sugar over medium heat. Stir until the sugar melts and turns an amber color.
  • Quickly add the marinated catfish to the pot. Turn off the heat and sear the fish on both sides, ensuring it’s coated in the caramel sauce.
  • Pour the marinade into the pot along with enough boiling water to just cover the fish. Add the peppercorns. Cover with a lid and simmer on low heat for at least 1 hour. (For an even richer flavor, braise for 2-3 hours.) Avoid stirring or moving the fish during this time, as it becomes very tender and can easily break apart.
  • If there’s too much liquid after braising, remove the lid and cook over medium-high heat until the sauce thickens to your desired consistency.
  • Serve the braised fish with steamed rice.
