Bake the kale for 10 minutes on 375 degrees F. Check frequently to see if the pieces are becoming crispy and golden (it also can go from golden brown to charred and bitter very quickly!). Some pieces may need to be turned over. Turn off the oven and leave the trays in for another 2 to 5 minutes to finish the drying process.
Once you remove the trays from the oven, squeeze a little extra lemon over them and serve.
