Spanish potato omelette, also known simply as potato omelette, is one of the most emblematic and representative dishes of Spanish cuisine. Its origin dates back to the 19th century, although there are various theories about its creation, the most accepted one being that of General Tomás de Zumalacárregui during the Carlist Wars in the Basque Country, who needed a simple, nutritious, and economical recipe to feed his troops. Over time, this preparation has transcended borders and is very popular in different Latin American countries, where it is known by slightly different names. For example, in Mexico and Central America it is called "Spanish omelette" or simply "potato omelette," in Argentina and Uruguay it is common to refer to it as "potato omelette," and in Chile, in addition to "Spanish omelette," variations with onion or even cheese are frequently included.
The Spanish omelette is appreciated for its simplicity, modest ingredients, and the comforting flavor it provides. Its versatility allows it to be enjoyed both hot and cold, whether as a main dish, side, or tapa, establishing itself as a symbol of home and traditional cooking.
