Preheat your oven to 350°F (175°C).
Wash the kale thoroughly and dry it using a salad spinner or paper towels.
Tear the kale leaves into bite-sized pieces, discarding the thick stems.
In a large bowl, toss the kale with olive oil until evenly coated.
Sprinkle sea salt over the kale and toss again.
Spread the kale in a single layer on a baking sheet.
Optionally, add your favorite seasonings like garlic powder or paprika.
Bake in the preheated oven for about 15-20 minutes.
Check the kale frequently to avoid burning; they should be crispy but not charred.
Remove from the oven and let cool before serving.
