Preheat oven to 250 degrees F.
Prepare the sweet potatoes by washing and peeling them. You can skip peeling their skin if you wish to. It’s my preference to peel the skins.
Remember to pat dry your sweet potatoes thoroughly with a paper towel before starting to slice them.
By using a mandolin slicer create thin chips for uniform cooking. If you don’t have a mandolin, use a very sharp knife and cut slowly to get these uniformly thins.
Cutting them uniformly is the key. Otherwise, the thick parts of the slices won't crisp up all the way.
Toss slices with olive oil so that each thin slice is lightly coated.
I don’t prefer to add salt in this recipe. You can, however, add salt, pepper and any other spices of your choice to add flavors to these chips.
Lay the chips on the baking sheet lined with parchment paper.
Bake for approximately 90 to 120 minutes till the sweet potato thins are crisp and lightly brown.
After baking, allow the chips to rest for ten minutes. During this time, the tender parts of the chips will continue to crisp up too.
Serve with your favorite dip.
