Sprinkle catfish evenly with 1/4 teaspoon salt and 1/4 teaspoon black pepper. Set aside.
Combine breadcrumbs, remaining 1/4 teaspoon salt, 1/4 teaspoon garlic powder, and 1/4 teaspoon ground red pepper in a shallow bowl.
Whisk egg whites in a shallow bowl until frothy. Dip fillets in egg whites, and dredge in breadcrumb mixture.
Arrange fillets on a wire rack coated with cooking spray in an aluminum foil-lined 15- x 10-inch jellyroll pan. (Do not overlap fillets.) Lightly coat fillets evenly on both sides with cooking spray.
Bake at 375° for 25 to 30 minutes or until fish is golden brown. Serve with Lemon Cream. Garnish, if desired.
*1 cup plain dry breadcrumbs may be substituted for panko breadcrumbs.
