Instructions

  1. Step 1: Peel and dice 450g potatoes into 1/4-inch cubes. Thinly slice 150g yellow onions into rings. Heat 60ml extra virgin olive oil in a 10-inch nonstick skillet over medium heat until shimmering (350°F/177°C).
  2. Step 2: Add potatoes and onions to the skillet, season with 1 tsp salt, and cook covered for 25 minutes, stirring once, until potatoes are fork-tender and onions are translucent.
  3. Step 3: Whisk 4 large eggs in a bowl until fully combined. Add to the skillet with potatoes and onions, gently folding to coat. Cook uncovered over medium-low heat for 10-12 minutes until edges set and center is softly set.
  4. Step 4: Carefully flip the tortilla using a plate: slide it onto a plate, invert, and return to skillet. Cook for another 5-7 minutes until golden brown and center is set. Let rest 5 minutes before slicing into wedges.
