Ingredients

Instructions

  1. Step 1: Heat 4 tbsp extra virgin olive oil in a large nonstick skillet over medium heat. Add 3 medium peeled and thinly sliced potatoes and 1 thinly sliced medium onion. Cook gently, stirring occasionally, for 20 minutes until potatoes are soft but not browned.
  2. Step 2: In a large bowl, whisk 6 large eggs with 1 tsp salt and 1/4 tsp black pepper until frothy.
  3. Step 3: Drain the cooked potatoes and onions through a colander to remove excess oil, then gently fold them into the beaten eggs.
  4. Step 4: Heat remaining 2 tbsp olive oil in a 9-inch nonstick skillet over medium heat. Pour the egg, potato, and onion mixture into the skillet and cook for 5-6 minutes until the edges begin to set.
  5. Step 5: Carefully invert the tortilla onto a large plate, then slide it back into the skillet to cook the other side for 4 minutes until fully set and golden.
  6. Step 6: Slide the tortilla onto a serving plate and let it rest for 5 minutes before slicing into wedges.
