Potatoes are a key ingredient in Spanish tortillas.
The Spanish tortilla is a dish traditionally made with eggs, potatoes and onions. Potatoes and onions are fried in oil and added to beaten eggs. The ingredients are then cooked in a skillet until the eggs begin to harden, then the tortilla is flipped over to allow the other side to cook. Some recipes may require the addition of other ingredients, such as chorizo, bacon, chili, chives, or cheese. Tortillas are very popular in Spain and are often served as a main entree to any meal or can be eaten as a snack.
Eggs are typically used to make Spanish tortillas.
When making a Spanish tortilla, the potatoes and onions are prepared first. Potatoes are thinly sliced and cooked in oil until tender but not browned. Olive oil is generally used, but butter or other types of oils can be substituted. Onions can be cooked in the same pan as potatoes and are usually placed in the skillet when the potatoes are halfway through cooking. After sauteing, the excess oil from the potatoes and onions is drained and added to a bowl of beaten eggs. The ingredients are mixed until well combined.
The egg mixture is then typically cooked in a deep skillet over medium to high heat. When the bottom of the Spanish tortilla is firm, lightly browned and crispy, flip it over to cook the other side. In some regions of Spain, a tortilla is flipped only once, while in other parts of the country it can be flipped multiple times until cooked through. A nonstick skillet with slanted sides is often used to make it easier to flip the tortilla. If turning is too difficult for a novice cook, the tortilla can be placed in the oven to finish cooking.
Although a traditional Spanish tortilla only consists of eggs, potatoes and onions, there are many variations on the classic recipe. Common additions include chorizo, bacon, chili and chives. Some people prefer to melt the cheese on top of the tortilla. The recipe is very versatile, making it easy to modify a Spanish tortilla according to the taste of the person making it.
Spanish tortillas are very popular and can be served for breakfast, lunch or dinner in that country. They are also commonly eaten as an aperitif or snack throughout the day. A tortilla can be served hot, cold or at room temperature.
