How long should you fry a haddock filet?

Fry a haddock fillet for about 3 to 4 minutes per side over medium heat, depending on the thickness of the fillet. The fish is done when it flakes easily with a fork and has a golden-brown crust. Be careful not to overcook it, as haddock can become dry if left on the heat too long. Always ensure the internal temperature reaches 145°F (63°C) for safe consumption.
