Preheat your oven's broiler. Grease a broiling pan or line pan with
aluminum foil. In a small bowl, mix together the Parmesan cheese,
butter, mayonnaise and lemon juice. Season with dried basil, pepper,
onion powder and celery salt. Mix well and set aside.
Arrange fillets in a single layer on the prepared pan. Broil a few
inches from the heat for 2 to 3 minutes. Flip the fillets over and
broil for a couple more minutes. Remove the fillets from the oven and
cover them with the Parmesan cheese mixture on the top side. Broil
for 2 more minutes or until the topping is browned and fish flakes
easily with a fork. Be careful not to over cook the fish.
