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.

Salt and freshly ground pepper. Preheat the broiler and broiling pan for 10 minutes.(The concentrated heat will cook the bottom side of the fish, eliminating the need to turn it over.) Meanwhile, melt the butter in a heavy saucepan over low heat.lace the fish on the rack and pour about 2 tablespoons of butter sauce over it. Broil the fish 5-6 minutes at a distance of 3 1/2 to 4 inches from heat. If placed too close to heat, the fish will burn.
