  • When coating the chicken, it is easier to use tongs as the protein powder gets sticky when using hands.
  • Method to coat chicken, place on top of protein powder mix in shallow bowl and push down.  From top sprinkle protein powder.  Flip chicken piece over and repeat until chicken piece is evenly coated. 
  • Once coated, put immediately into deep fryer as the protein powder soaks up liquid if set aside for too long.
  • Make sure deep fryer is set to 325°F and not higher temperature as the protein powder tends to cook fast and want to make sure coating and chicken cook evenly.
  • The boneless chicken thighs take about 6-8 minutes to cook.  
  • The center of the chicken should reach 165°F to be at safe temperature to eat.
