Pre-heat oven at 375’F

Wash potatoes and slice into even rounds, aim for about ¼” thick (it is very important to make sure they are even for even cooking, best to use a mandolin if you have one)

Generously cover a sheet tray with oil

Place a single layer of potatoes on the tray

Bake 20-40 minutes, cook time depends on how thick you cut the rounds

Keep watch, do not let the potatoes burn

Half way through cooking, flip the rounds over so they brown evenly

Remove from oven, sprinkle with kosher salt

Serve hot with a ton of ketchup

NOTE:

I just recently discovered a faster and easier way to make these that does not require the use of the oven, just a microwave, a small pan and cooking oil.

Wash a potato, pierce a few times, and microwave using the potato setting for baked potatoes

When potato is done cooking, remove from microwave and slice into good size slices

Warm cooking oil in a small non-stick pan over medium-high heat

Pan fry potato rounds until golden on both sides

Remove from oil, place on paper towel to drain, sprinkle with kosher salt

Serve hot
