Ingredients

Instructions

  1. Step 1: Heat 1/4 cup olive oil in a 10-inch nonstick frying pan over medium heat. Add 3 peeled and thinly sliced medium potatoes and 1 thinly sliced medium yellow onion. Cook gently, stirring occasionally, for 15 minutes until potatoes are tender but not browned.
  2. Step 2: In a large bowl, beat 6 large eggs with 1 tsp salt and 1/2 tsp black pepper until combined.
  3. Step 3: Using a slotted spoon, transfer the potatoes and onions to the eggs, mixing gently to coat.
  4. Step 4: Remove excess oil from the pan, leaving about 1 tbsp. Pour the egg mixture back into the pan and cook over medium-low heat for 6-8 minutes until the edges are set and the bottom is golden.
  5. Step 5: Carefully invert the tortilla onto a plate, then slide it back into the pan to cook the other side for 4 minutes until fully set and lightly browned.
  6. Step 6: Slide the tortilla onto a serving plate, let cool for 5 minutes, then slice and serve warm or at room temperature.
