Ingredients You’ll Need

Getting started on this Cast-Iron Skillet Blackened Catfish Recipe is delightfully straightforward. Each ingredient plays an essential role—from the fresh catfish fillets forming the heart of the dish, to the Creole Cajun seasoning that layers on the bold flavors, and the butter that adds richness and helps create that beautiful sear. Together, these simple components work in harmony to deliver a stunning meal.

• 2 lbs catfish fillets: Choose fresh, firm fillets for the best flaky texture after cooking.
• 1 tablespoon olive oil: Helps the Cajun seasoning adhere and enhances the searing process.
• 2 tablespoons Creole Cajun Seasoning: This spice mix is your flavor powerhouse, delivering depth and heat—feel free to use homemade or store-bought.
• 4 tablespoons unsalted butter: Melts into the pan to create a rich base for the perfect blackened crust.
• Lemon wedges: Provide a bright, fresh contrast when squeezed over the finished catfish.

How to Make Cast-Iron Skillet Blackened Catfish Recipe

Step 1: Prep and Season the Catfish

First off, let your catfish fillets come to room temperature for about 20 minutes. This is a little trick that helps the fish cook evenly and ensures a perfect sear when blackening. After that, pat the fillets dry with paper towels to remove excess moisture, preventing steam that would hinder the crust formation. Drizzle olive oil on both sides, then massage your Cajun seasoning in thoroughly for full-bodied flavor in every bite. Let the fish rest with the seasoning while you heat your skillet.

Step 2: Heat the Skillet and Melt Butter

Place your trusty cast-iron skillet over medium-high heat and add the unsalted butter. You want it melted and just barely sizzling—this sizzling butter is what creates the iconic blackened crust without burning the spices. Swirl the skillet gently so the butter coats the entire surface, prepping it to sear the catfish perfectly.

Step 3: Blacken the Catfish Fillets

Carefully lay two fillets at a time into the hot skillet, skin side down if your fillets have skin, or simply with the side you prefer to present. Let the fish cook undisturbed for 3 to 5 minutes until a deep, dark crust forms; this is the hallmark of a well blackened catfish. Flip the fillets gently with a fish spatula to cook the other side for an additional 1 to 2 minutes. The fish should feel firm but still tender and easily flake when done.

Step 4: Serve Hot and Fresh

Remove the fillets to a clean platter as they finish and repeat with the remaining catfish. Serve immediately with bright lemon wedges to squeeze over the top for that citrusy pop. This dish shines best right off the stove, letting the crispy blackened coating and juicy fish interior take center stage.

Garnishes

Simple garnishes bring this Cast-Iron Skillet Blackened Catfish Recipe to life. Fresh lemon wedges are a classic that cut through the smoky spice beautifully. For a little extra color and texture, chopped fresh parsley or green onions sprinkled on top can brighten the presentation and add a mild freshness that balances the bold seasoning.

Side Dishes

This catfish pairs exceptionally well with robust Southern sides. Imagine creamy Cajun dirty rice seasoned with spices, or a rich crawfish cream sauce to spoon lavishly over the fish. Light sides like a crisp green salad or warm cornbread work equally well, providing contrasts that keep the meal well-rounded and satisfying.

Creative Ways to Present

Want to step things up? Serve your blackened catfish over a bed of sautéed greens or atop fluffy grits for a true Southern comfort experience. Alternatively, flaky catfish can be tucked into soft tortillas with fresh slaw and a drizzle of remoulade sauce for fish tacos that impress. The possibilities with this Cast-Iron Skillet Blackened Catfish Recipe are endless and worth experimenting with!

Make Ahead and Storage

Storing Leftovers

If you have leftovers, transfer them into an airtight container and refrigerate within two hours after cooking. The catfish will stay good for up to 3 days, though it’s best enjoyed as fresh as possible to keep the crispy blackened coating intact.

Freezing

Freezing cooked blackened catfish is possible but not ideal because the texture can become a bit mushy after thawing. If you must freeze, wrap each fillet tightly in plastic wrap and then place in a freezer-safe bag. Use within 1 month for best flavor. Thaw slowly in the refrigerator before reheating gently.

Reheating

To bring back some of that initial crispiness when reheating, use a hot skillet with a little oil over medium heat. Gently warm the fillets on each side for a few minutes instead of using the microwave, which tends to soften the crust and affect the texture.

FAQs

Can I use frozen catfish fillets for this recipe?

Yes, but it’s best to fully thaw and pat them dry before cooking to ensure an even blackened crust and to avoid excess moisture that prevents proper searing.

What can I substitute for Creole Cajun seasoning?

If you don’t have pre-made Cajun seasoning, you can mix your own with paprika, cayenne pepper, garlic powder, onion powder, thyme, oregano, salt, and pepper. Adjust cayenne for your preferred spice level.

Is a cast-iron skillet necessary?

While you can use other heavy-bottomed pans, a cast-iron skillet is ideal because it retains high heat evenly, which is essential for achieving that blackened crust without burning.

How spicy is this recipe?

This dish has a nice kick from the Cajun seasoning, but you can control the heat by adjusting the amount of cayenne pepper in your seasoning blend or choosing milder versions.

Can I double the recipe for a larger group?

Absolutely! Just cook the catfish in batches to avoid overcrowding the skillet, which can cause steaming instead of searing the fillets.
