Lay piece of parchment in shallow baking dish. Place beets on top of parchment, pierce with fork, and season with 1/4 tsp salt, 1/4 tsp pepper, and olive oil. Wrap beets tightly in parchment and roast for 50 to 60 minutes until tender. Rest in parchment for 30 minutes, or until cool enough to handle. Unwrap beets and remove skins with knife, then cut into segments.
