Preheat the oven to 425°F.
Scrub the beets under cold running water and pat dry with a towel. Drizzle with olive oil and season with salt.
Wrap the beets in aluminum foil and place on a baking sheet in the oven to roast for 40-60 minutes (depending on their size) until fork tender.
Allow the roasted beets to cool slightly before running under cold water to remove the skin.
Season with salt, slice and serve.
