Easy Savory Cajun-Style Blackened Catfish Fillets

Blackened catfish is one of those dishes that feels special but comes together fast. It’s all about that spicy crust seared on the fish for a smoky, bold flavor. Cooking catfish this way keeps it tender inside while giving you a crispy, flavorful outer layer. It’s a straightforward dinner to whip up on a busy evening when you want something hearty but uncomplicated.

The Story Behind This Recipe

I first tried blackened catfish when visiting Louisiana years ago. It was served simply, with just some lemon wedges and a straightforward side of rice. The spice blend was the star, and the fish practically melted on the tongue. It stuck with me — how just a handful of spices and good heat could transform a humble fish into something memorable.

Since then, I’ve adapted the recipe for home cooking, dialing down the heat just a bit so it’s approachable but still lively. The best part is the quick sear in a hot pan. It creates that signature crust without needing a grill or fancy equipment.

I usually serve this with a simple side salad or steamed veggies and maybe some crusty bread. It’s a meal that comes together quickly after a long day but still feels thoughtfully made. Plus, catfish is affordable and widely available, making it a practical choice for weeknight dinners.

The seasoning mix is versatile too. I keep a batch ready in a jar and sometimes sprinkle it on chicken or shrimp to switch things up. It’s one of those blends that brings warmth and depth without too much fuss.

Ingredients

  • 2 catfish fillets (about 6 ounces each)
  • 2 teaspoons smoked paprika
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1/2 teaspoon cayenne pepper
  • 1/2 teaspoon dried thyme
  • 1/2 teaspoon dried oregano
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 2 tablespoons vegetable oil or butter
  • Lemon wedges, for serving

Instructions

  1. Step 1. Mix paprika, garlic powder, onion powder, cayenne, thyme, oregano, salt, and black pepper in a small bowl to make the blackening seasoning.
  2. Step 2. Pat the catfish fillets dry with paper towels. Sprinkle the seasoning evenly on both sides of each fillet, pressing gently to adhere.
  3. Step 3. Heat the oil or butter in a heavy skillet over medium-high heat until hot but not smoking.
  4. Step 4. Carefully place the fillets in the skillet. Cook without moving for about 4 minutes until the underside is dark and crusty.
  5. Step 5. Flip the fillets carefully and cook for another 4-5 minutes until the fish is opaque and flakes easily with a fork.
  6. Step 6. Remove from the pan and let rest for a minute before serving with lemon wedges on the side.

Tips for Success

  • Make sure the pan is hot before adding the fillets to get that nice crust.
  • Don’t overcrowd the pan; cook in batches if necessary to maintain the right heat.
  • Patting the fish dry before seasoning helps the spices stick and promotes browning.
  • Adjust cayenne pepper to your heat preference; you can skip or reduce it if you prefer milder flavors.

Variations & Substitutions

  • Try the seasoning on chicken breasts or shrimp for a quick alternative.
  • Serve with a side of dirty rice or Cajun-style roasted potatoes for a fuller meal.
  • Add a squeeze of hot sauce or a simple remoulade for some extra tang.
