In a shallow bowl, combine the bread crumbs, Parmesan cheese, parsley and seasonings. Dip catfish in butter, then in crumb mixture. Arrange on a sheet pan.
Bake, uncovered, at 375° until fish just begins to flake easily with a fork, 20-25 minutes. In the last minute or so, turn your broiler on and while watching closely, crisp up or add a little more browning to the fish. I think this helps to solve the lack of crispiness you have because you are not frying the fish in hot oil.
If desired, serve with tartar sauce and lemon wedges.
