What main vegetable is used to make a potato waffle?

The main vegetable used to make a potato waffle is the potato.

Potato waffles are savory foods formed into a waffle-like grid, typically from potatoes combined with vegetable oil, seasonings, and sometimes potato starch or potato granules. They are not ordinary sweet waffles with a little potato added; the potato provides the dish’s central structure and flavor.

The food is especially common in the United Kingdom and Ireland. Commercial frozen potato waffles became popular during the expansion of home freezers and convenience foods in the 1970s and early 1980s. Birds Eye began producing its well-known potato waffles in 1981, promoting them with the slogan “waffly versatile.”

Potato waffles are commonly baked, grilled, or toasted from frozen and served with breakfast foods such as eggs and bacon. Recipes vary: some use mashed potato, while manufactured versions may include potato starch, stabilizers, rice flour, or dextrose. Turnip, parsnip, and carrot can appear in vegetable waffles, but they do not define the standard potato waffle.
