To roast fresh beets, cut the greens off (they can also be cooked and eaten), scrub the outsides, rub with a small amount of olive oil, wrap tightly in foil and place on a baking sheet. Roast on 400 degrees for 45-60 minutes depending on size. (a knife should be easily inserted)
When the beets have cooled they can be used right away or kept in the fridge for a week or so. To use, unwrap and gently rub the skin-it will come right off. Slice and enjoy.
