Wash and dry the kale leaves well in advance of roasting to ensure that they are completely dry. Serve these highly snackable chips in a wide, shallow dish, or cool to room temperature in a single layer so they don’t steam and become soggy. Either way, serve soon after roasting.
Position a rack in the center of the oven and heat the oven to 375°F.
Pile the kale on a large rimmed baking sheet. Toss with the olive oil and vinegar. Sprinkle the lemon zest over the kale and then season very lightly with salt.
Spread the kale evenly on the baking sheet and roast until it has begun to steam and dry out around the edges of the leaves, about 5 minutes. Using tongs, toss the kale, keeping it evenly distributed, and rotate the baking sheet to ensure even cooking. Continue to roast until the kale is dark green and shatteringly crisp, 7 to 10 minutes more. Some of the edges may begin to brown. Serve hot or at room temperature soon after roasting.
