Blackened Catfish

About This Recipe

Blackened catfish is the dish that carried Cajun cooking to national fame: fillets dipped in melted butter, crusted in a paprika-heavy spice blend, and seared in a screaming-hot cast-iron skillet until the coating chars into a smoky, peppery shell. The technique, popularized by chef Paul Prudhomme in 1980s New Orleans, is not burning — it is the controlled blackening of butter and spices into a crust that seals in the mild, flaky fish. Done properly it takes minutes, produces dramatic smoke, and delivers an intensity of flavor that belies the short ingredient list. Open a window, heat the pan, and commit.

Ingredients

Serves 4

• 4catfish fillets (6–7 oz each)(under 1 inch thick; completely patted dry)
• 0.5 cupunsalted butter(melted; for dipping and finishing)
• 1.5 tbspsmoked paprika
• 1 tspcayenne pepper
• 1 tspgarlic powder
• 1 tsponion powder
• 0.5 tspdried thyme
• 0.5 tspdried oregano
• 1 tspkosher salt
• 0.5 tspblack pepper
• 2 wholelemons(halved, for squeezing at service)

Instructions

1. 1

   Prepare

   Pat the catfish fillets completely dry and stir together paprika, cayenne, garlic powder, onion powder, thyme, oregano, salt, and black pepper. Melt a stick of butter and set up plates for dipping and dredging.

2. 2

   Cook

   Heat a dry cast-iron skillet over high heat for 8 to 10 minutes until it is smoking hot; this extreme heat is what blackens rather than steams. Turn on the vent fan and open a window first.

   Blackening produces serious smoke; many Louisiana cooks do it outdoors on a burner for good reason.

3. 3

   Combine

   Dip each fillet in melted butter, press the spice blend onto both sides, and lay it in the skillet. Sear 2 to 3 minutes per side without moving, until the crust is deeply browned, nearly black, and the fish flakes.

   Do not nudge the fillets early — the crust releases cleanly only once it has fully set.

4. 4

   Serve

   Transfer to plates, spoon a little extra melted butter over the top, and finish with a hard squeeze of lemon. Serve immediately with dirty rice, coleslaw, or grilled vegetables.

Variations

• •

  Blackened redfish: the original Prudhomme dish, using the same butter-and-spice method.

• •

  Blackened catfish tacos: flake the fish into warm tortillas with slaw and chipotle crema.

• •

  Lighter pan-bronzed version: medium-high heat and half the butter for less smoke and a gentler crust.

• •

  Blackened shrimp: same crust, 90 seconds per side, for po-boys or pasta.

Storage

Best eaten immediately while the crust is crisp. Refrigerate leftovers up to 2 days and reheat in a hot dry skillet for 2 minutes per side; the microwave softens the crust and overcooks the fish.
