Preheat oven to 300 degrees F.
Remove the kale leaves from the stems and tear them into bite-sized pieces.
Wash and dry the kale thoroughly (use a salad spinner or kitchen towel to make sure they are completely dry before the next step).
Add the dry kale leaves to a large bowl and drizzle with the olive oil, shaking to coat each piece.
Spread the kale out onto a parchment-lined baking sheet, making sure the leaves aren't touching each other, and bake for 10 to 20 minutes. This really depends on your oven and the size of the kale pieces. Keep an eye on them, you want them to be crispy but not burnt!
As soon as they come out of the oven, sprinkle with salt or your favorite seasoning blend (you can get creative here). Adding the salt and seasoning is best done at the end or else they can easily get over-seasoned. You can season them before baking but consider yourself sufficiently warned 😊.
