Kale is one of my all-time favorite greens (although, honestly, how many people really keep a list of their favorite greens in mind?) This robust, leafy vegetable is extremely versatile and packed with flavor. Unlike with some hearty greens, such as collards and Swiss chard, kale is delicious both cooked and raw. In this particular recipe lacinato kale is baked up into crispy, delectable chips. Try not to get too addicted.
Preheat the oven to 300 degrees.
Meanwhile, cut or tear the kale into bite-sized pieces and arrange them on a baking sheet lined with parchment paper or aluminum (for easy clean-up), making sure not to overlap the pieces so that they can bake evenly. Coat the kale with olive oil, salt, and half of the crushed red pepper flakes. Bake them for 20 minutes, checking occasionally to make sure the chips don't burn.
Remove the pan from the oven and let the chips cool slightly, then toss gently with the remaining crushed red pepper flakes and truffle oil. Serve immediately or store in an air-tight container.
