Start by setting your oven to 350 degrees F for preheating. If using an air-fryer or CrispLid, preheat them at 350F for 6 minutes.
Prepare your baking sheet or air-fryer basket by lining it with parchment paper.
Keep your kale leaves ready by removing the stems and tearing the leaves into bite size pieces.
In a small bowl, mix the oil, salt, pepper and the seasoning. Toss the leaves in the mixture.
Spread the leaves in a single layer on the baking sheet or on the air-fryer/CrispLid basket.
Bake until the leaves turn crispy and the edges brown. The process takes 10 to 15 minutes.
After baking the kale leaves will look shrunken due to loss of water.
Allow the leaves to cool on the counter for a few minutes.
Enjoy with your favorite dip.
