This classic Spanish dish can be served for breakfast, cut in cubes for tapas, or as a summer lunch with a bowl of gazpacho. A quick note: Add the potato mixture while it's hot enough to start cooking the eggs but not so hot as to souffle them.
This tortilla recipe is a staple of Spanish gastronomy. The Tortilla Espanola is simple, versatile, and full of flavor.
Yield: serves 4-8
3⁄4 cup Spanish olive oil
6 medium russet potatoes, peeled, quartered, and thinly sliced
1 medium yellow onion, peeled, halved, and thinly sliced
Heat oil over medium-high heat in a 10" saute pan. Add potatoes and onions and cook, lifting and turning, until potatoes are soft but not brown, about 20 minutes.
Beat eggs in a large bowl until pale yellow. Transfer sauteed potatoes and onions with a slotted spoon to beaten eggs. Reserve oil.
Heat 1 tbsp. reserved oil in the same pan over medium heat. Add egg and potato mixture, spreading potatoes evenly in the pan. Cook uncovered until the bottom is lightly browned, about 3 minutes.
Gently shake pan so tortilla doesn't stick, then slide a spatula along edges and underneath tortilla. Place a large plate over pan and quickly turn plate and pan over so tortilla falls onto plate. Add 1 tsp. reserved oil to pan, slide tortilla back in (uncooked side down), carefully tuck in sides with a fork, and continue cooking over medium heat until eggs are just set, about 3 minutes. Cut into wedges and serve at room temperature.
