Regular potato chips even french fries need to be washed to get the starch off. Then they need to be dried, before you put them in the oil. I would think slicing the beets thin then try frying them. I don't think they have starch--sugar yes. When they come out of the grease salt them. If this is not working for you, then try washing them in cold water, take out and dry then try frying them. I'd think the first way would work with beets.
