Peel and slice potatoes into thick slices, approximately ¼ inch thick, then place slices in a large bowl of cold water, let sit for 20 minutes. Then drain well and towel dry.
Pre heat oven to 375F (190C), line a large baking sheet or two with parchment paper.
On a small plate whisk together the flour, parmesan cheese, parsley and salt.
Brush one side of the potato slices with olive oil and then coat in parmesan cheese mixture place on prepared cookie sheet coating side down.
Brush top side of slices with olive oil and sprinkle with remaining parmesan mixture. Spray or drizzle with a little extra olive oil.

Notes
You can use an air fryer to make these, they take approximately 15-20 minutes to bake and at a temperature of 400F (200C).These are best served and eaten as soon as they are baked, although if you do have leftovers, place them in an airtight container and microwave or warm in a pre-heated oven before serving.
