Ingredients:
4 large potatoes (Yukon Gold or other waxy potatoes)
1 large onion
6 large eggs
1 cup olive oil (for frying)
Salt to taste
Instructions:
1. Prepare the potatoes and onions:
Peel the potatoes and slice them thinly (about 1/8 inch thick).
Peel and thinly slice the onion.
2. Cook the potatoes and onions:
Heat the olive oil in a large, deep skillet over medium heat.
Add the sliced potatoes and onions to the skillet. Cook them gently, stirring occasionally, until the potatoes are tender but not browned (about 15-20 minutes). The potatoes should be soft but not falling apart.
Use a slotted spoon to remove the potatoes and onions from the oil and drain them on paper towels. Season with salt to taste.
3. Prepare the egg mixture:
In a large bowl, beat the eggs and season with a pinch of salt.
Add the cooked potatoes and onions to the beaten eggs and mix gently to combine.
4. Cook the tortilla:
Heat a small amount of the reserved olive oil in a non-stick skillet over medium heat.
Pour the potato, onion, and egg mixture into the skillet, spreading it out evenly.
Cook the tortilla over medium-low heat until the edges are set and the bottom is golden brown (about 5-7 minutes).
Carefully flip the tortilla using a large plate or lid. Slide the tortilla back into the skillet to cook the other side until it is fully set and golden brown (about 5 minutes).
5. Serve:
Slide the tortilla onto a serving plate and let it cool slightly before slicing.
Serve warm or at room temperature, cut into wedges.
