Place kale in large bowl and toss with 2 tablespoons olive oil, making sure to coat each leaf. Evenly space kale onto baking sheets so leaves do not overlap. Sprinkle kale with sea salt.
Bake at 350 F for 5 minutes then switch baking sheets from top rack to bottom rack and bake for an additional 5 minutes. Cool before serving.
For extra flavor, sprinkle with finely grated Parmesan cheese before baking.
*Use remaining greens to try a simple sauté or add kale to your favorite pasta dish
