Add the lemon to the butter make sure the two are combined.
Drizzle the lemon butter mixture over the fish.
Bake fillets at 450 degrees for about 8-12 minutes depending on thickness. (Check the fillets at 8 minutes by putting a fork in the center/thickest part. The fillets are done when the fish is easy to flake with the fork.)
