Lay out your potato slices on paper towel to absorb some moisture. Blot the top of potatoes as well.
Heat oil on high flame in a large sauté pan so that it comes ¼ to ½ way up sides.
Heat oil until ready- breadcrumbs dropped in will bubble or wooden spoon end will bubble when immersed.
Place potato slices in oil in one layer (don’t over crowd the pan!), then using tongs flip potatoes after about 2- 3 or until browned. Brown on other side.
Remove “chips” to paper towel lined plate and sprinkle with S & P, repeat with additional potatoes.
Serve with ketchup if you want or just enjoy as is!
