Step-by-Step Instructions

Step 1: Prep the Catfish Fillets

Rinse the fillets under cold water and pat them completely dry with paper towels. If you’re using frozen catfish, make sure they’re fully thawed. For even cooking, trim or cut larger fillets into similar sizes.

Step 2: Soak in Buttermilk

Place the fillets in a shallow dish and pour the buttermilk over them. Add a few dashes of hot sauce if you’d like a bit of extra flavor. Let them soak for 20 to 30 minutes. This step helps tenderize the fish and tones down any strong flavors.

Step 3: Prepare the Coating

In a shallow bowl, combine the cornmeal, flour, Cajun seasoning, lemon pepper, paprika, salt, and black pepper. Stir until everything is evenly mixed. This seasoned coating is the key to that golden crunch.

Step 4: Dredge the Fillets

Remove the catfish from the buttermilk, shaking off any excess liquid. Coat each fillet generously in the cornmeal mixture, pressing lightly so the coating sticks well. Set the coated fillets on a plate or wire rack and let them rest for 5–10 minutes so the crust can set.

Step 5: Preheat and Load the Air Fryer

Preheat your air fryer to 400°F for 3–5 minutes. Lightly spray the basket with olive oil. Arrange the fillets in a single layer, leaving space between each piece. Lightly spray the tops of the coated fillets with olive oil as well.

Step 6: Air Fry Until Crispy

Cook the catfish for 10 minutes at 400°F, then carefully flip them. Spray again with olive oil and cook for another 6–8 minutes. If your fillets are especially thick, add 2–3 minutes more. The fish is done when the coating is deep golden and the internal temperature reaches 145°F.

Step 7: Rest and Serve

Let the catfish rest for 2 minutes before serving. Sprinkle with a little extra salt, squeeze on some fresh lemon juice, and serve hot with tartar sauce, coleslaw, or your favorite Southern sides.

Storage & Make-Ahead Tips

• Refrigerating leftovers: Store cooled catfish fillets in an airtight container in the refrigerator for up to 3 days. To keep the coating from softening, line the bottom of the container with a paper towel to absorb excess moisture.
• Reheating for crispiness: The best way to bring back the crunch is to reheat in the air fryer. Heat at 375–400°F for 3–5 minutes, flipping once. Avoid the microwave, which makes the coating soggy.
• Freezing raw breaded fillets: After coating, place the fillets on a parchment-lined tray and freeze until solid. Transfer to a freezer bag and store up to 2 months. Cook straight from frozen at 380°F for 6 minutes, flip, then finish for 8–10 minutes more until golden and cooked through.
• Make-ahead prep: Mix the dry coating ingredients ahead of time and keep them sealed in a jar for up to 1 week. You can also soak the catfish in buttermilk up to 1 hour before cooking, keeping it chilled until ready to dredge and air fry.

Serving Suggestions

-> Crispy air fryer catfish is best enjoyed hot and fresh, with a squeeze of lemon to brighten its golden crust. To give it that full Southern charm, pair it with sides like creamy coleslaw, hush puppies, cornbread, or mac and cheese. A dollop of tartar sauce or remoulade on the side adds just the right tangy balance.

-> For a lighter spread, serve the catfish with roasted vegetables, a crisp garden salad, or steamed green beans. It also makes a fantastic fish sandwich, tuck a fillet into a soft bun with lettuce, tomato, and a drizzle of spicy aioli.

-> And if you’re feeling creative, use the fillets as the star of fish tacos with shredded cabbage and a smoky chipotle cream sauce. However you plate it, don’t forget a few lemon wedges and a sprinkle of fresh parsley for that final fresh touch.

FAQs

Do I need to soak the catfish before cooking?
Yes, soaking in buttermilk (with a little hot sauce if you like) for 20–30 minutes helps tenderize the fish and removes any muddy flavor that catfish sometimes has.

Can I cook the catfish without buttermilk?
Absolutely. You can use regular milk with a splash of lemon juice or vinegar as a substitute, or skip the soak and season the fillets directly.

What temperature should I cook catfish in the air fryer?
400°F works best for crispy results. Cook 18–20 minutes total, flipping halfway, until the coating is golden and the fish reaches 145°F internally.

Can I use frozen catfish fillets?
Yes, but thaw them completely for the best coating and even cooking. If cooking from frozen, expect to add a few minutes to the cook time.

How do I reheat leftovers so they stay crispy?
Reheat in the air fryer at 375–400°F for 3–5 minutes. Avoid microwaving, which makes the coating soggy.

Can I use this method with other fish?
Yes, tilapia, cod, haddock, or even trout work well with this same coating and air fryer method. Just adjust the cooking time based on thickness.
