I wash them off with vinegar. Helps to remove some of the wax. Then put them in the oven like a baked potato for about 30 minutes at 400 degrees. then let them cool enough to handle them. Toss a little oil fry them up like fried potatoes and season. Have done the same with carrots. One night had a rutabaga, carrot and a sweet potato. put them into the oven at same time. Did the oil toss and fry. Nice change for side dish. Thing is you can do this ahead of time.
