how long to cook blackened fish
Brush both sides of catfish fillets with butter. Rub fillets with the cayenne pepper mixture on both sides. Heat a large heavy skillet over medium-high heat until really hot. Add fillets, and fry approximately 2 minutes on each side, until slightly blackened. Arrange blackened fillets in a single layer in the prepared baking dish, and coat with Italian-style salad dressing. Bake 30 to 35 minutes in the preheated oven, until fish is easily flaked with a fork.
