Optional - lemon slices and fresh herbs for serving.
Instructions
Preheat the broiler to 525 degrees and prepare a broiler pan or baking sheet by lining with aluminum foil and using a light coating of cooking spray.
In a small bowl, use a spoon to mix together the Parmesan cheese, butter, mayonnaise and lemon juice. Season with dried parsley, pepper, onion powder and 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 2 more minutes.
Remove the fillets from the oven and spread 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. Internal temp should read 145 degrees F.
Serve with lemon slices and chopped herbs if desired.
