Add oil to a heavy bottomed skillet, roughly 1/2 inch high, and heat to 350°.
canola oil
While the oil's heating, add the potato flakes to a paper plate. Set aside. Crack the eggs in a shallow bowl, add the water, and whisk together until smooth. Set aside.
1 4 oz pkg mashed potato flakes, 5 eggs
Pat the chicken dry on both sides using paper towels. Then, working with one piece at a time, add the chicken to the egg wash- turning to evenly coat.
6-8 frozen chicken breast tenderloins
Let excess egg wash drip off the chicken, then transfer it to the potato flakes, turning to evenly coat and pressing in gently to ensure it sticks- if necessary.
Repeat for a second coating of both egg wash and potato flakes, the transfer the prepared chicken to a waiting plate and continue, one piece at a time, until all the chicken's been double coated.
Using tongs carefully transfer the chicken to the hot oil, working in batches of 3-4 to avoid overcrowding, and fry for 4-5 minutes- flipping as needed.
Transfer the cooked chicken to a paper towel lined plate to drain off excess grease and cool, repeating until all the chicken's been fried.
Serve warm and enjoy!
