1 Begin heating the oil over medium high heat. 2  If you have a deep fat frying thermometer, use it! 3  The best temperature is 350 to 375 degrees F. 4  If you don't have a thermometer, the oil is ready when a 1 cube of white bread dropped into the oil browns in 60 seconds; that oil temperature will be about 365 degrees F.
