1Heat the oven to 375°F and arrange a rack in the middle. Rinse the beets and trim off any leafy tops. Wrap completely in aluminum foil and place in the oven. Roast until tender and easily pierced with a knife, about 1 to 1 1/2 hours. Remove from the oven and let cool.
2When the beets are cool enough to handle, peel using a paring knife or by pushing the skin with your fingers.
3Slice the beets, drizzle with olive oil, and season with salt and freshly ground black pepper.
