Preheat an oven to 350°F. Line a cookie sheet with parchment paper. (Can use foil/ rack or omit to preference.)

Remove the stems from the leaves and break into bite size pieces.

Wash and thoroughly dry.

Coat the leaves lightly with the olive oil. Sprinkle with salt if desired, or lightly once on baking pan.

Bake until the edges brown, but are not burnt. This can take 8 to 10 minutes depending on your oven, so if first time making kale chips, be sure to watch and rotate trays half way.

Season to taste.
