Tortilla de patatas (Spanish Omelet)

6-7 medium potatoes, peeled
1 whole yellow onion
5-6 large eggs
2-3 cups of olive oil for pan frying
Salt to taste

Cut the peeled potatoes in half lengthwise. Then, with the flat side on the cutting surface, slice the potato in pieces approximately 1/8" thick. If you slice them a bit thick, don’t worry – it will simply take a bit longer for them to cook.

Peel and chop the onion into 1/4" pieces. Put potatoes and onions into a bowl and mix them together. Salt the mixture.

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 them 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.

Leave in 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 and allow oil to drain.

Crack the eggs into a large mixing bowl and beat by hand with a whisk or fork. Pour in the potato onion mixture. Mix together with a large spoon.

Pour 1-2 Tbsp of olive oil into a small, non-stick frying pan (aprox. 9-10”) and heat on medium heat. 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.” 

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 3-4 minutes. Turn the heat off and let the tortilla sit in the pan for 2 minutes.

Slide the omelet onto a plate to serve. If eating as a main course, cut the omelet into 6-8 pieces like a pie. Serve sliced bread on the side.
If you are serving as Tapas, slice a baguette into pieces about 1/2 inch think. Cut the tortilla into 1.5” squares and place a piece on top of each slice of bread.

Cooking Tips

Make it spicy adding some chillies before frying the potatoes. You can either leave or remove the chillies. 
Mojo picón sauce fits also very well with tortilla.
