Preheat the oven to 400°F. Place the salmon fillet on a sheet of aluminum foil, then top with butter and season with Italian seasoning, salt, and black pepper.

Fold the foil around the salmon and seal it into a loose packet so the fish can steam gently while baking.

Bake for 15 minutes, or until the salmon flakes easily with a fork and reaches your preferred doneness.

Carefully open the foil packet, serve hot, and spoon any buttery juices over the salmon before serving.
