Add the seasoned flounder fillets to the pan when the oil begins to shimmer. Saute the flounder for roughly 3 to 4 minutes per side, or until the flesh becomes opaque and is firm to the touch. If you are unsure if the fish is done, use an instant-read thermometer. The flounder is thoroughly cooked if the internal temperature is 145 Fahrenheit.
Watch the cook time on the flounder, 15 minutes is a long time to cook flounder. Mine was ready after 5 minutes of cooking. This unfortunately did not work out for us at all. I am reviewing without stars for now, though, in case it was the fault of the fish we picked up this afternoon, although it was fresh.
