Preheat the oven to 375 degrees F and set the rack in the low position.

Spray a 9x13-inch pan with cooking spray or brush it with oil. If using a rimmed sheet pan, cover it with parchment paper.

Rinse the fish and pat it dry.

Season both sides of the fish with salt and pepper.

Arrange the fish in a single layer on the baking pan.

Season the fish with Old Bay seasoning or any other seafood seasoning of your choice.

Cube the butter and scatter the cubes over and around the fish.

Place the pan in the oven and bake for 10-15 minutes or until the fish easily flakes with a fork.

Remove the pan from the oven and scatter parsley over the fish.

Plate servings and spoon butter over each fillet. Serve with lemon wedges.
