Preheat your air fryer to 360ºF (180ºC). Remove the stems and rip or slice the leaves into large uniform pieces. They shrink up in the oven, so don't cut them too small.
4-5 cups kale
Place kale in a large bowl. Drizzle with lemon juice and season with desired amount of salt and paprika. Add any other spices that you would like (find more flavor variations here). Use clean hands to massage all ingredients into the kale leaves.
1/2 lemon, 1 teaspoon salt, 1 teaspoon paprika
Add your seasoned kale to the air fryer basket making sure not to pack them too tightly. We divided ours into 2 batches for a 6 quart air fryer. Cook for 4-5 minutes, then move the kale leaves around to redistribute and continue cooking for a couple more minutes at 320°F (160°C) until crispy.
The kale leaves will fly around in the drawer since they're so light. If you have an extra tray or basket with your air fryer to set on top of them feel free to use it.
Notes
