Preheat the oven to 180°C (350°F) and line a baking sheet with parchment paper or a silicone mat.
Wash and peel the vegetables if desired; then, using a mandoline or sharp knife, slice them as thinly and evenly as possible—about 1-2 mm thick. Thinner slices will crisp up better in the oven.
Place the vegetable slices in a large bowl, drizzle with olive oil, and toss gently to coat each piece lightly and evenly. This helps them crisp up and prevents sticking.
Add a pinch of sea salt and smoked paprika to the bowl, then toss again so the spices are distributed evenly across all slices.
Arrange the slices in a single layer on the prepared baking sheet, making sure they don’t overlap too much. Space is key for even crisping.
Bake in the middle rack for 15-20 minutes, checking after 12 minutes. Keep an eye on the edges—they can brown quickly—so rotate the sheet if needed to promote even baking.
Once the chips are golden, blistered, and crisp to the touch, remove the baking sheet from the oven and let the chips rest for about 5 minutes. They will continue to crisp as they cool.
Transfer the chips to a wire rack if you want them extra crispy, or serve directly from the baking sheet. Enjoy them at room temperature for the best crunch and flavor.
