Cast-Iron Skillet Blackened Catfish Recipe
Introduction
Blackened catfish cooked in a cast-iron skillet is a flavorful and simple dish that brings bold Cajun spices right to your table. With a crispy, seasoned crust and tender fish inside, this recipe is perfect for a quick weeknight dinner or a gathering with friends.

Ingredients
- 2 lbs catfish fillets, about 4 pieces
- 1 tablespoon olive oil
- 2 tablespoons Creole Cajun seasoning (homemade or store-bought)
- 4 tablespoons unsalted butter
- Lemon wedges, for squeezing over blackened catfish fillets and serving
Instructions
- Step 1: Let the catfish fillets sit on the counter for 20 minutes to come to room temperature. This helps the fish cook evenly and enhances the blackening process.
- Step 2: Pat the catfish dry with paper towels. Place the fillets on a small baking sheet or platter. Drizzle olive oil over them and use your hands to coat both sides evenly. Season generously with Cajun seasoning, pressing the spices into the fish.
- Step 3: Heat a large cast-iron skillet over medium-high heat and add the butter. Once melted and sizzling slightly, swirl the skillet to coat the bottom evenly.
- Step 4: Working in batches, place two fillets in the pan, skin side down if applicable. Let them sear without moving for 3-5 minutes until a deep crust forms.
- Step 5: Carefully flip the fillets and cook for another 1-2 minutes until the fish feels firm and flakes easily with a fork. Transfer fillets to a clean plate or serving platter.
- Step 6: Repeat with remaining fillets. Serve immediately with lemon wedges and your favorite sides.
Tips & Variations
- Use a well-seasoned cast-iron skillet to enhance the crust and prevent sticking.
- For extra heat, add cayenne pepper to the Cajun seasoning mix.
- Try serving with Cajun dirty rice or a creamy crawfish sauce for a complete Southern-inspired meal.
- Patting the fish dry before seasoning ensures a better sear and crust formation.
Storage
Store leftover blackened catfish in an airtight container in the refrigerator for up to 2 days. Reheat gently in a skillet over low heat to maintain crispness, or warm briefly in the oven. Avoid microwaving to keep the crust from becoming soggy.

FAQs
Can I use a non-cast-iron skillet for blackening catfish?
While a cast-iron skillet is ideal for even heat and a good sear, you can use a heavy-bottomed stainless steel or non-stick pan. Just be sure to preheat the pan well and monitor cooking times closely.
What is the best way to make homemade Cajun seasoning?
A simple Cajun seasoning blend includes paprika, garlic powder, onion powder, cayenne pepper, dried oregano, dried thyme, salt, and black pepper. Adjust the cayenne for your preferred heat level and mix all spices thoroughly for a balanced flavor.

Ingredients
Catfish and Seasoning
- 2 lbs catfish fillets, about 4 pieces
- 1 tablespoon olive oil
- 2 tablespoons Creole Cajun Seasoning (homemade or store-bought)
Cooking
- 4 tablespoons unsalted butter
- Lemon wedges, for squeezing over blackened catfish fillets and serving
Instructions
- Bring Catfish to Room Temperature: Let the catfish fillets sit on the counter for 20 minutes to come to room temperature. This step ensures the fish cooks evenly and facilitates the blackening process.
- Season the Catfish: Pat the fillets dry with a paper towel. Place them on a small baking sheet or platter, drizzle olive oil over both sides, and use your hands to coat evenly. Generously season with Creole Cajun seasoning, massaging the spices onto all surfaces of the fillets. Set aside for at least 15 minutes to let the flavors penetrate.
- Heat the Skillet and Add Butter: Preheat a large cast-iron skillet over medium-high heat. Add the unsalted butter and swirl the skillet once it melts and begins to barely sizzle, coating the bottom evenly.
- Blacken the Catfish: Working in batches, carefully place two catfish fillets skin-side down into the skillet. Allow them to sear undisturbed for 3-5 minutes until a deep, flavorful crust forms. Flip the fillets using a fish spatula or slotted utensil and cook for another 1-2 minutes until the fish is firm, tender, and flakes easily with a fork.
- Serve: Transfer the cooked catfish to a clean plate or serving platter. Repeat the process with remaining fillets. Serve immediately with lemon wedges for squeezing and your favorite side dishes for a complete Southern-inspired meal.
Notes
- Letting the catfish come to room temperature ensures even cooking and better blackening.
- Patting the fish dry before seasoning helps the spices adhere better and achieve a crispy crust.
- Use a cast-iron skillet for optimal heat retention and even searing.
- Do not move the fish once placed in the pan to allow a crust to form properly.
- Serve with Cajun Dirty Rice or Crawfish Cream Sauce for an indulgent Southern feast.
