Prepare a baking pan with a wire rack.
Remove kale leaves from stems. Wash and dry the kale leaves thoroughly. Preferably use a salad spinner to dry kale leaves. Additionally, use paper towels to dry kale leaves as well. Remove as much moisture as possible.
Break up Kale in a few pieces and place in a medium-size bowl with olive oil and salt. Toss the kale so all leaves are coated.
Place kale leaves on the rack of the baking pan in a single row (none on top of each other).
Bake for 1 hour and remove the kale chips that are done. If any need longer, bake for 10 minutes, check, until all are done.
Store in an air tight container.
