Preheat your oven to 180°C (350°F) and line a baking sheet with parchment paper.
Peel the plantains and slice them as thinly and evenly as possible—about 1/8 inch—using a mandoline or a sharp knife.
Transfer the slices to a mixing bowl, then drizzle lightly with olive oil. Toss gently to coat each slice evenly, ensuring they’re just coated without excess oil.
Add a pinch of sea salt and smoked paprika if using, then toss again to distribute the seasonings evenly.
Arrange the slices in a single layer on the prepared baking sheet, leaving space between each to promote even baking.
Bake in the preheated oven for 12-15 minutes, watching closely after 12 minutes. The chips are done when they turn golden brown and crispy around the edges.
Once baked, transfer the chips immediately to a cooling rack to stop the cooking process and help them crisp up further.
Let the chips cool for about 5 minutes until fully crisp. Taste and sprinkle with additional salt or seasonings if desired while still warm.
Serve the chips once cooled slightly—enjoy their light, crunchy texture and smoky flavor as a healthy snack or side.
