Heat a skillet to medium heat and add the oil or butter to the pan.
Season the walleye filets generously with lemon pepper seasoning, Cajun, or ramp salt.
Place the fish over the melted butter.
Then put an upside down pan over top of the fish. This creates steam in the inside of the pan.
Cook the fish 4 to 5 minutes per side or until the fish reaches a temperature of 145 degrees. The walleye will turn white when it is done cooking.
