Step 1

Bring the salmon to room temperature 20 minutes before grilling.

Step 2

Preheat the oven to 450 degrees F. Set a large cast-iron grill pan over low heat and pre-heat for 1 minute.

Step 3

Meanwhile, brush the salmon lightly with the oil and season with salt and pepper.

Step 4

Raise the heat under the grill pan to medium-high. Place the salmon, skin-side up on the grill, at an angle across the ridges of the pan. Cook until the fish has distinctive grill marks, about 3 minutes. To make cross-hatched grill marks, use a spatula to re-position the fillets about 45 degrees (keep the skin-side up). Cook 2 minutes more. Turn the salmon over, and transfer the grill pan to the oven. Continue cooking the fish in the oven for 2 to 3 minutes for pink inside, 5 minutes for medium, and 7 minutes for well done.

Step 5

Remove the fish from the pan, and let rest for 2 minutes, to finish cooking. (If the skin comes loose during cooking, you may remove and discard it before serving, if desired.) Serve.
