Spanish Omelette, or as they call it in Spain “tortilla de patatas” or potatoes omelette, is a real treat of an omelette. There are many versions around that are just not the proper thing. This is the real and authentic Spanish Omelette recipe.
It’s simple, it only uses olive oil, potatoes, eggs, onions and salt. Nothing else. Resist the temptation to add ingredients like chorizo or cheese (which I have seen). You will never find those in a real Spanish Omelette, and to be honest, the authentic Spanish omelette cannot be improved. This is simply the best recipe you will find. Buen provecho!
