Step 1

With your hand at least 12 inches away, lightly sprinkle salt and black pepper on both sides of fish fillets in a single layer, right before cooking.

Step 2

Preheat a large heavy non-stick or stainless-steel skillet over high heat (hot but not smoking). Lower heat to medium, heat the oil for a few seconds, and let it spread accross the pan.

Step 3

Cook fish fillets, skin-side up for 90 seconds - 2 minutes, until lightly browned. Carefully flip the fish fillets and cook the skin for 3 minutes.

Step 4

Add butter, thyme, and fresh lemon juice to pan. Tilt the pan slightly and use a spoon to baste the fish with melted butter. Continue basting until cooked through for about 1 minute or more, depending on the thickness of the fish.
