Start by washing your kale thoroughly. It’s important to dry the leaves completely—any moisture will keep them from getting crispy. You can pat them dry with a clean kitchen towel or use a salad spinner.
Once dry, remove the thick stems from the kale leaves. You’ll want to tear the kale into bite-sized pieces, roughly the size of a chip. The leaves will shrink as they cook, so don’t make them too small.
In a large bowl, drizzle the kale with 1 tablespoon of olive oil. Massage the oil into the kale to ensure the leaves are evenly coated.
After the oil, sprinkle on your seasonings of choice. Salt and pepper are a must, but you can add garlic powder, paprika, or any other flavors you like. Give the kale a good toss to make sure each leaf is covered.
Place the kale leaves in the air fryer basket in a single layer. If you have a lot of kale, you may need to cook it in batches.
Set your air fryer to 375°F (190°C) and cook the kale for 4 to 6 minutes. Halfway through, give the basket a good shake to ensure even cooking. Keep a close eye on the kale during the last minute—because it’s thin, it can go from perfectly crispy to burnt pretty quickly.
Once the kale is done, remove it from the air fryer and let it cool for a minute or two. The chips will crisp up even more as they cool.
