This fried catfish recipe uses a buttermilk marinade and cornmeal coating to create crispy, golden fish that’s tender inside and full of classic Southern flavor.
In a large bowl, whisk together the buttermilk, mayonnaise, and dill pickle juice until smooth and well combined.
Add the catfish fillets to the buttermilk marinade, turning to coat evenly. Cover and refrigerate for at least 2 hours, or up to 8 hours for more flavor.
In a shallow dish or bowl, combine the cornmeal, flour, Old Bay seasoning, seasoned salt, and black pepper. Mix well so the spices are evenly distributed throughout the mixture.
Pour oil into a large, heavy skillet to a depth of about 1 ½ inches. Heat the oil over medium-high heat until it reaches 350 F. The oil should immediately sizzle when a pinch of the breading is dropped in.
Remove the catfish from the marinade and transfer it to a strainer, letting the excess liquid drip off. Dredge each fillet in the cornmeal mixture, pressing lightly to ensure the coating adheres well. Add each breaded fillet to a large plate or platter to rest for 10-15 minutes.
Carefully place the coated fillets into the hot oil, working in batches to avoid overcrowding. Fry for 3-4 minutes per side, or until golden brown and the fish flakes easily with a fork. The internal temperature of the catfish should be 145 F when measured at the thickest part of the fillet.
Transfer the fried catfish to a sheet pan with a wire rack to drain.

Notes
Letting the breaded fish rest before frying makes a big difference in keeping the coating intact.
Maintain oil temperature between batches for the crispiest results.
Do not overcrowd the skillet or the fish will steam instead of fry.
