Instructions
-
Place the catfish fillets in a large bowl or shallow dish. Pour the buttermilk and 1 tablespoon of hot sauce over the fish, turning to coat evenly. Cover and refrigerate for at least 20 minutes (up to 1 hour) to tenderize the fish and remove any 'muddy' flavor.
~20 minDo not leave the fish in buttermilk for more than 2 hours or the texture will become mushy. -
In a wide, shallow dish (like a pie plate), whisk together the cornmeal, flour, garlic powder, onion powder, paprika, cayenne pepper, black pepper, and kosher salt until thoroughly combined.
~3 minMixing a little flour with the cornmeal is the secret to a crust that stays bound to the fish and fries up exceptionally crunchy. -
Pour the peanut or vegetable oil into a large cast-iron skillet until it is about 1 to 1.5 inches deep. Attach a deep-fry thermometer and heat the oil over medium-high heat until it reaches 350°F to 365°F.
~8 minMaintaining the correct oil temperature is crucial to prevent greasiness. If the oil is too cool, the fish will absorb it; if too hot, the crust will burn before the fish cooks. -
Set up a wire cooling rack over a baking sheet. Remove a catfish fillet from the buttermilk mixture, letting the excess drip off. Place it into the cornmeal dredge, pressing firmly so the mixture adheres heavily to both sides. Shake off any loose excess and carefully place it on a clean plate. Repeat with the remaining fillets.
~5 minLet the dredged fillets rest for about 5 minutes before frying to help the coating set. -
Carefully lower 2 fillets into the hot oil, slipping them in away from you to prevent splattering. Fry for 3 to 4 minutes per side, until the crust is deep golden brown and the fish flakes easily with a fork.
~8 minDo not overcrowd the pan. Frying in batches ensures the oil temperature doesn't drop too much. -
Use a fish spatula or tongs to remove the fried catfish from the oil and transfer immediately to the prepared wire rack. Do not drain on paper towels, as the steam will make the crust soggy.
~2 minSprinkle the fish with a tiny pinch of salt as soon as it comes out of the oil for maximum flavor. -
Allow the oil to return to 350°F before frying the remaining fillets. Serve hot, accompanied by lemon wedges and plenty of your favorite hot sauce.

Tips & Storage
- Draining the fried fish on a wire cooling rack instead of paper towels is the biggest secret to retaining a crispy crust and avoiding a greasy bottom.
- If you only have coarse cornmeal, pulse it a few times in a food processor or blender to get a finer texture, which coats the fish better.
- For extra spice, double the cayenne pepper in the dredge or add more hot sauce to the buttermilk marinade.
- Peanut oil is highly recommended for frying due to its high smoke point and the subtle, authentic flavor it imparts.
- Storage: Store leftover catfish in an airtight container in the refrigerator for up to 3 days. To reheat and restore crispness, place on a wire rack over a baking sheet and bake in a 400°F (200°C) oven for 10-12 minutes. Do not microwave.
