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.
Lutefisk can also be boiled directly in a pan of water. Lutefisk sold in North America may also be cooked in a microwave oven. The average cooking time is 8â10 minutes per whole fish (a package of two fish sides) at high power in a covered glass cooking dish, preferably made of heat resistant glass.utefisk does not need additional water for the cooking; it is sufficient to place it in a pan, salt it, seal the lid tightly, and let it steam cook under a very low heat for 20â25 minutes. An alternative is to wrap in aluminium foil and bake at 225 Â°C (435 Â°F) for 40â50 minutes.
