01 - Gently pat the catfish fillets dry using paper towels to remove excess moisture. This promotes crispiness during frying.
02 - In a shallow dish, combine the buttermilk and hot sauce. Add the dried catfish fillets, ensuring each piece is thoroughly coated. Allow the fish to marinate for 10–15 minutes.
03 - In a separate shallow dish, thoroughly mix together the cornmeal, all-purpose flour, Cajun seasoning, salt, black pepper, and paprika until well combined.
04 - Pour 1 quart of vegetable oil into a deep skillet or fryer. Heat the oil to a precise temperature of 350°F (175°C).
05 - Carefully remove the marinated fillets from the buttermilk mixture, allowing any excess liquid to drip off. Dredge each fillet generously in the prepared cornmeal mixture, pressing lightly to ensure an even and complete coating.
06 - Working in small batches to avoid overcrowding, fry the coated fillets for 4–5 minutes per side, or until they achieve a rich golden-brown color and are thoroughly cooked through.
07 - Transfer the freshly fried catfish fillets to a wire rack or layers of paper towels to drain any residual oil, maintaining their crisp texture.
08 - Serve the crispy Louisiana-style fried catfish immediately while hot, optionally garnished with fresh lemon wedges and a side of tartar sauce.
