Baked Sweet Potato Chips

Preheat oven to 250°F and position oven rack in the center of the oven.
Rinse and dry your sweet potatoes thoroughly.
Slice them as uniformly thin as possible. If you have a mandolin, use it. Otherwise, use a very sharp knife to get these uniformly thin.

Know that chips that are too thick in parts won't crisp up all the way. Still delicious, just not "chip" crispiness.
Toss slices in olive oil to lightly coat, then again with salt.
Lay out in a single layer on a baking sheet and bake for up to 2 hours, flipping chips once halfway through to ensure even cooking.

Baking time depends on the thickness of the chips. Really thin chips only require 30 minutes.
Remove once crisp and golden brown. Some may feel a little tender in the middle but take them out and let them rest for 10 minutes or so to crisp up before sampling.
Serve immediately.
