What French-fry variant is made with sweet potatoes instead of white potatoes?

A French-fry variant made with sweet potatoes instead of white potatoes is called sweet potato fries.

The preparation follows the basic French-fry method: sweet potatoes are cut into sticks or julienne pieces and fried, baked, or air-fried. Their orange, cream, or purple flesh gives the finished fries a different appearance and a naturally sweeter, more earthy flavor than fries made from ordinary white potatoes.

Sweet potato fries are not defined by a particular cut. They can be straight-cut, shoestring, crinkle-cut, or waffle-cut. The name identifies the main ingredient, while terms such as “crinkle-cut sweet potato fries” describe the shape. They are commonly served with ketchup, mayonnaise-based sauces, aioli, barbecue sauce, or spicy dips.

Recipes for fried sweet potatoes in the United States date to the nineteenth century, although the modern restaurant-style side became especially widespread later. In New Zealand, sweet potato fries may be called kūmara fries, using the Māori word for sweet potato. Despite their reputation as a healthier choice, their nutrition depends heavily on whether they are fried, baked, or heavily coated.
