How to Make Caramelized Onion Tortilla

  1. Heat 2 tablespoons of olive oil in a large (12-inch) skillet over medium heat.
  2. Add 2 large yellow onions, thinly sliced.
  3. Cover and cook for 15 minutes, stirring halfway through.
  4. Reduce heat to low.
  5. Cook, covered, stirring occasionally, until onions are very soft and golden brown (about 45 minutes). Let cool for 10 minutes.
  6. In a medium bowl, whisk together 8 large eggs, 1/2 teaspoon salt, and 1/4 teaspoon black pepper.
  7. Gently stir the caramelized onions into the egg mixture.
  8. Heat the remaining 2 tablespoons of olive oil in a 10-inch nonstick skillet over medium heat.
  9. Pour the egg-onion mixture into the hot skillet.
  10. Cook undisturbed for 3 minutes. Then, gently loosen the edges with a spatula, tilting the pan to allow uncooked egg to flow underneath. Continue cooking until the eggs are almost set but still slightly moist (about 10-12 minutes).
  11. Place a large plate over the skillet.
  12. Holding the plate and skillet firmly together, invert them to transfer the tortilla to the plate.
  13. Carefully slide the tortilla back into the skillet, browned side up.
  14. Cook for 5 minutes, or until the bottom is browned and the inside is cooked through but still moist.
  15. Slide the tortilla onto a serving plate. Cut into wedges and serve hot, warm, or at room temperature. Garnish with fresh sage leaves (optional).
