01 - Gently pat the catfish fillets dry with paper towels to remove excess moisture.
02 - In a shallow dish, combine buttermilk and hot sauce. Submerge the catfish fillets, ensuring they are fully coated. Allow to marinate for 10 to 15 minutes.
03 - In a separate shallow dish, thoroughly combine the cornmeal, all-purpose flour, Cajun seasoning, salt, black pepper, and paprika.
04 - Heat vegetable oil in a deep skillet or fryer to a temperature of 350°F.
05 - Carefully remove the marinated fillets from the buttermilk, allowing any excess liquid to drip off. Dredge each fillet thoroughly in the prepared cornmeal mixture, pressing lightly to ensure an even coating.
06 - Fry the coated fillets in batches for 4 to 5 minutes per side, or until they achieve a golden brown color and are fully cooked through.
07 - Transfer the fried catfish to a wire rack or paper towels to drain any excess oil.
08 - Serve the fried catfish immediately with fresh lemon wedges and tartar sauce, if desired.
