I think that’s why most people just roast them whole in the oven. It’s makes everything so much cleaner, so much easier. At the end of a long work day, the last thing you want to do is get your hands dirty peeling beets. But then there’s the lovely golden beet. The beauty of the golden beets is that you can peel and chop them up before roasting without staining your hands.

Baby beets simply roasted to bring out their sweetness need just the barest slip of butter and a sprinkling of fresh rosemary. Candy cane beets, if you can find them at a farmers' market, look especially festive, but so does a medley of red and yellow ones. If baby beets are unavailable, cut peeled roasted large beets into 1-inch cubes.

Fresh beets, which you can simply cover with foil and roast in the oven, are healthy, easy to prepare, and taste absolutely delicious. Who would have thought that peeling them first, and thus caramelizing them in the oven, would glorify this humble root vegetable to new heights? Of course, red beets are a pain to peel.
