Preheat the oven to 375°F and line a baking sheet with foil.
Place the salmon, skin side down, onto the foil. Brush the pink flesh with ghee and sprinkle the salt and pepper evenly on top. Fold the sides of the foil up and around the fish to lock in the moisture.
Bake the salmon for 10 minutes OR 5 minutes per ½" of thickness measuring from the thickest part of the filet. Serve immediately.
