What is Blackened Catfish?

The blackening technique was popularized in Louisiana, where chefs used high heat and a flavorful rub to create a darkened, almost charred crust on fish. Unlike deep frying, blackening relies on spices, oil, and butter to achieve its signature color and taste. The result is smoky, slightly spicy, and full of depth without overpowering the natural flavor of the catfish.

How to Make Blackened Catfish

1. Prepare the Rub

In a shallow dish, combine the smoked paprika, brown sugar, oregano, garlic powder, cumin, salt, and cayenne. Mix until evenly blended.

2. Season the Fish

Pat the catfish fillets dry with paper towels. Dredge each fillet in the rub, coating thoroughly. Shake off any excess seasoning.

3. Heat the Cooking Surface

Preheat a cast iron skillet or Blackstone griddle over medium-high heat. Add the canola oil and spread evenly. Stir in the butter, allowing it to melt until foamy.

4. Cook the Catfish

Place the seasoned fillets on the hot surface. Cook for about 3 minutes on each side, until the exterior is deeply browned and crisp, and the fish flakes easily with a fork.

5. Serve

Remove from heat and serve immediately.

Expert Tips

• Use the right pan: Cast iron is ideal because it retains heat and helps create the perfect crust.
• Mind the heat: Preheating is crucial — the blackening process relies on high heat to sear the spices into the fish.
• Adjust the spice: Increase or decrease cayenne pepper to match your preferred heat level.
• Cook quickly: Catfish cooks fast; avoid overcooking to maintain a moist, flaky texture.
