Instructions

  1. Step 1: Peel and slice 500 grams of medium potatoes into 1/8-inch thick rounds and dice 1 medium onion into thin strips.
  2. Step 2: Heat 100 ml extra virgin olive oil in a 10-inch nonstick frying pan over medium heat. Add the sliced potatoes and onions, seasoning with 1 tsp salt and 1/2 tsp black pepper, then cook gently for 20 minutes, stirring occasionally, until potatoes are tender but not browned.
  3. Step 3: In a large bowl, beat 6 large eggs until homogeneous.
  4. Step 4: Using a slotted spoon, transfer the potatoes and onions to the bowl with eggs, mixing gently to combine without breaking the potatoes.
  5. Step 5: Remove excess oil from the pan, leaving about 2 tbsp. Pour the egg, potato, and onion mixture back into the pan and cook on medium-low heat for 6-8 minutes until the edges set and the bottom is golden.
  6. Step 6: Place a large plate over the pan and carefully invert the tortilla onto it. Slide the tortilla back into the pan to cook the other side for 4-5 minutes until fully set and golden.
  7. Step 7: Slide the cooked tortilla onto a serving plate, let rest for 5 minutes, then slice into wedges and serve warm or at room temperature.
