Instructions

  1. Step 1: Heat 2 tbsp extra-virgin olive oil in a 10-inch nonstick skillet over medium heat. Add 1 large thinly sliced yellow onion and cook for 10 minutes, stirring occasionally, until caramelized and golden brown—do not let it burn.
  2. Step 2: Add 1.5 lbs thinly sliced heirloom potatoes to the skillet, pressing them down gently to form an even layer. Drizzle with remaining 1 tbsp olive oil, season with 1/2 tsp sea salt, and cover with a lid. Cook for 15 minutes on medium-low, checking occasionally to prevent sticking.
  3. Step 3: In a small bowl, whisk 4 large eggs with 1 tsp lemon zest and 2 tbsp chopped parsley. Pour the egg mixture evenly over the potatoes while the skillet is still hot. Cover with a lid and cook for 4 minutes until eggs set but still slightly runny.
  4. Step 4: Carefully flip the tortilla using a large plate—place the plate over the skillet, flip quickly, and slide the tortilla back into the skillet to cook the egg side for 2 more minutes until golden and crisp.
