French fries are one of the world's most popular side dishes, made by cutting potatoes into uniform strips, soaking or drying them, and then deep-frying them until they achieve a crispy, golden-brown exterior and a soft, fluffy interior . Though their exact origins are highly debated between Belgium and France, they became a global phenomenon largely driven by the rise of modern American fast-food chains. Today, they are enjoyed in countless variations—from thin matchstick fries and thick-cut potato wedges to seasoned curly and waffle-cut shapes—and are traditionally paired with classic condiments like ketchup, mayonnaise, or vinegar, as well as serving as the canvas for loaded dishes like Canadian poutine or chili cheese fries.
