What is a popular fried side dish made from sliced potatoes?

The popular fried side dish made from sliced potatoes is French fries. This dish typically involves cutting potatoes into thin strips and deep-frying them until golden and crispy. French fries are a staple in many cuisines around the world and are often served as a side to burgers, sandwiches, or just on their own as a snack with various dips like ketchup or mayonnaise.

While potato chips, hash browns, and curly fries also feature potatoes and are fried, they differ in preparation and presentation. Potato chips are usually thinly sliced and fried until crispy, but they are often enjoyed as a snack rather than a side dish. Hash browns are primarily made from grated or finely chopped potatoes and are usually pan-fried rather than deep-fried. Curly fries are a specific style of French fries that are spiral-cut and seasoned, but they are still categorized under the broader definition of fries. Therefore, the most accurate answer to the question is French fries, as they represent the classic method of frying sliced potatoes.
