Prairie turnips (Psoralea esculenta) are the starchy, protein-rich roots of a legume native to the North American Great Plains. When raw, they have a firm, crisp texture similar to a jicama or water chestnut, with a mild, earthy, and slightly nutty flavor. They are a standout for their high fiber content and notable plant-based protein for a root vegetable.

How were prairie turnips traditionally prepared?
They were often peeled, sliced, and sun-dried into thin chips for long-term storage. The dried chips could be rehydrated in soups or ground into a flour to thicken stews and make bread.
Can I eat prairie turnips raw?
Yes, they can be eaten raw when young and tender, offering a crisp, nutty flavor. However, cooking is recommended for older roots and for easier digestion.
