Ingredients

  • 4 medium russet potatoes
  • 2 tsp olive oil
  • 1/4 tsp salt
  • Cracked black pepper to taste

Instructions

  • Preheat the oven to 400°F / 200°C.
  • Line a baking tray with parchment paper.
  • Peel the russet potatoes.
  • Wash the potatoes thoroughly under cool water.
  • Pat the potatoes dry with a clean kitchen towel or paper towel.
  • Slice the potatoes thinly and evenly using a sharp knife or a mandoline slicer.
  • Place the potato slices on the prepared baking tray.
  • Drizzle the olive oil over the potato slices.
  • Sprinkle the salt and cracked black pepper evenly over the potatoes.
  • Toss the potato slices until they are lightly and evenly coated with the oil and seasonings.
  • Arrange the potato slices in a single flat layer on the parchment paper.
  • Ensure that the slices do not overlap, as overlapping may prevent proper crisping.
  • Place the baking tray in the preheated oven.
  • Bake for 15 to 20 minutes, or until the potato slices are golden, crisp on the edges, and tender in the center.
  • Remove the baking tray from the oven.

  • Serve warm as a side dish or snack with a preferred dip.
