Peel the potatoes and cut into long thin strips.
Soak them in water for 30 minutes.
While the potatoes are soaking make the Parmesan and flour mixture in a bowl with a lid.
Pre-heat oven to 400 degrees.
Cover a cookie sheet with tin foil and spray lightly with cooking spray.
After 30 minutes, pat the potatoes dry and place them into the flour Parmesan mixture, place the lid on tight and shake the potatoes until they are all covered.
Now place them on the baking pan and place in the oven for 20 minutes.
After 20 minutes, broil the fries for 1 minute.
You can also cook these in an air fryer for 20 minutes on 400 degrees.
