Tortilla española, one of Spain's most famous and beloved national dishes, is nothing more than egg, potato, and onion cooked in olive oil. And yet, when attention is paid to the technique, it's one of the most profoundly delicious dishes imaginable. Here's how to make it.
Not to be confused with the tortilla francesa (French omelette), the thick tortilla española is cooked in olive oil and features fried, thinly-sliced potatoes along with the eggs. While the tortilla española is usually kept to the basics of potatoes and eggs, sometimes you can find other vegetables - onion often makes an appearance- thrown into the mix for variety.
