Milcao is a traditional dish originating from the Chiloé Archipelago. It consists of grated potatoes, mashed potatoes, and usually lard and seasonings, resulting in a type of potato pancake. Traditionally, only Chilotan potatoes should be used in the preparation of milcao.

These potato pancakes are used as an important part of dishes reitimiento and curanto. Nowadays, there are many variations of milcaos – fried, oven-baked, steamed, boiled, sweetened, or enriched with chicharrones.
