Preheat the Oven: Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
Prepare the Beets: Peel the beets and slice them thinly using a mandoline or a sharp knife. The thinner the slices, the crispier the chips will be.
Season: In a mixing bowl, toss the beet slices with olive oil, sea salt, black pepper, and any additional seasonings you prefer until well coated.
Arrange on Baking Sheet: Spread the beet slices out in a single layer on the prepared baking sheet, making sure they do not overlap.
Bake: Bake in the preheated oven for 20-25 minutes, flipping halfway through, until the chips are crispy and slightly curled. Keep a close eye on them to prevent burning.
Cool and Serve: Remove from the oven and let the chips cool on the baking sheet for a few minutes before transferring them to a serving bowl. Enjoy your homemade beet chips!
