Preheat the oven to 350°F and position oven rack in the middle.
Remove the kale leaves from the stems. Rinse and dry.
Massage the olive oil onto the kale leaves so that every surface of each leave is covered.
Spread onto a single layer of the baking sheet and sprinkle a healthy amount of salt (so way more than “a pinch of salt”)
Bake for 15 minutes. At 15 minutes, the kale chips should be ready. If they’re not all crispy for your preference, leave in the oven with the heat turned off (but still hot) to allow for further crisping.
