Add massaged kale to air fryer in a single-ish layer. (It’s best to cook your chips in 2-3 batches, so the air fryer isn’t over-crowded.) If you have one, cover kale with a metal trivet/rack on top to keep the leaves in place while cooking. (This is optional, but recommended.)
Cook for 4-6 minutes, tossing halfway through, until crispy.
