Preheat the oven: Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper for easy cleanup or use a non-stick baking sheet.
- Prepare the radishes: Wash and trim the radishes. Cut off both ends and slice them into thin rounds, about 1/8 inch thick. The thinner the slices, the crispier the chips will be.
- Season the radishes: In a medium bowl, toss the radish slices with olive oil, salt, and pepper. Add garlic powder, paprika, or your seasoning of choice if desired.
- Arrange on the baking sheet: Spread the radish slices in a single layer on the prepared baking sheet, avoiding overlap for even baking.
- Bake the chips: Bake for 20-25 minutes, flipping the chips halfway through. Check for golden and crispy edges. Keep an eye on them towards the end to avoid burning.
- Cool and serve: Remove from the oven and cool on the baking sheet. The chips will crisp up further as they cool. Serve immediately or store in an airtight container once cooled.
