1 Cook The Beets With Their Peel On. I Prefer The Boiling Method Because It'S More Efficient - Cover The Beets With Water, Bring To A Boil, And Simmer For 30 Minutes Or Until Beets Can Easily Be Pierced Through With A Fork. Alternatively You Can Wrap The Beets In Aluminum Foil And Bake Them In The Oven At 400
