Then, cover the pan and cook for 5 to 8 minutes or until the fish is opaque and cooked to your preferred doneness. Once the thickest part of the fish reaches 130°-140°F on an instant-read thermometer, I take the pan off the heat. (I know the FDA says 145°F is the safe temperature for cooked fish, but for my tastes, that’s overdone. Instead, I refer to
this chart for fish cooking times.)
