What You’ll Need

  • 6 to 7 medium potatoes (peeled) 
  • 1 yellow onion (whole) 
  • 5 to 6 large eggs (the better the eggs, the better the tortilla) 
  • 2 to 3 cups of olive oil (for pan frying) 
  • 1/2 tablespoon salt (or to taste) 

How to Make It

  1. Cut the peeled potatoes in half lengthwise. Then, with the flat side on the cutting surface, slice the potato into pieces approximately 1/8″ thick. If you slice them thick, don’t worry—it will simply take a little longer for them to cook.
  2. Peel and chop the onion into 1/4″ pieces. Put potatoes and onions into a bowl and mix them together. Salt the mixture.
  3. In a large, heavy, non-stick frying pan, heat the olive oil on medium-high heat. Carefully place the potato and onion mixture into the frying pan, spreading it evenly over the surface. The oil should almost cover the potatoes. You may need to turn down the heat slightly, so the potatoes do not burn. You want them to slowly fry, not becoming crisp like french fries, but rather tender and creamy. It is important to use good olive oil, as the potatoes will absorb quite a bit of the oil.
  1. Leave the mixture in the pan until the potatoes are cooked. If you can poke a piece of potato with a spatula and it easily breaks in two, your potatoes are done. Remove from the pan with a slotted spoon or spatula that allows the oil to drain and let cool.
  2. Crack the eggs into a large mixing bowl and beat by hand with a whisk or fork. Pour in the cooled potato onion mixture. Mix together with a large spoon. Let sit for about five minutes.
  3. Pour 1 to 2 tablespoons of olive oil into a small, non-stick frying pan (approximately 9-10” in diameter) and heat on medium heat. Be careful not to get the pan too hot because the oil will burn—or the tortilla will! When hot, stir the potato onion mixture once more and “pour” into the pan and spread out evenly. Allow the egg to cook around the edges. Then you can carefully lift up one side of the omelet to check if the egg has slightly “browned.” The inside of the mixture should not be completely cooked and the egg will still be runny.
  4. When the mixture has browned on the bottom, you are ready to turn it over to cook the other side. Take the frying pan to a sink. Place a large dinner plate (12”) upside down over the frying pan. With one hand on the frying pan handle and the other on top of the plate to hold it steady, quickly turn the frying pan over and the omelet will “fall” onto the plate. Place the frying pan back on the range and put just enough oil to cover the bottom and sides of the pan. Let the pan warm for 30 seconds or so. Now slide the omelet into the frying pan. Use the spatula to shape the sides of the omelet. Let the omelet cook for 3 to 4 minutes. Turn the heat off and let the tortilla sit in the pan for 2 minutes.
  1. Slide the omelet onto a plate to serve. If eating as a main course, cut the omelet into 6 to 8 pieces like a pie. Serve sliced French bread on the side.
  2. If you are serving as an appetizer, slice a baguette into pieces about 1/2″ thick. Cut the tortilla into 1.5” squares and place a piece on top of each slice of bread.

It is simply delicious served with sofrito, fried tomato sauce that is made all over Spain. Tomatoes, onions, garlic, green peppers and olive oil sautéed in a frying pan. It’s also great with roasted red peppers.
