Classic Spanish Tortilla is a traditional thick omelette made with thinly sliced potatoes, onions, and eggs, cooked slowly in olive oil until tender and golden. It can be served warm or at room temperature, making it perfect for any meal or snack.

Ingredients

Scale
  • 4 medium potatoes, peeled and sliced thin (about coin thickness)
  • 1 medium onion, sliced thin
  • 5 large eggs
  • 1 cup olive oil (for frying)
  • Salt, to taste
  • Optional: black pepper, fresh parsley, or other herbs for extra flavor

Instructions

  1. Peel and thinly slice the potatoes and onion, about the thickness of a coin, for even cooking.
  2. Heat 1 cup olive oil in a large skillet over medium heat until hot but not smoking.
  3. Gently add the sliced potatoes and onions to the skillet and cook slowly, stirring occasionally, for 15-20 minutes until the potatoes are tender but not browned.
  4. Use a slotted spoon to remove the potatoes and onions from the oil and drain on a plate lined with paper towels to remove excess oil.
  5. In a large mixing bowl, lightly beat the 5 eggs with a pinch of salt.
  6. Fold the warm potatoes and onions into the beaten eggs gently to combine, then let the mixture rest a few minutes.
  7. Heat a little olive oil in a non-stick skillet over medium heat.
  8. Pour the egg and potato mixture into the skillet, spreading evenly.
  9. Cook gently for 5 to 7 minutes until the bottom is set and golden.
  10. Carefully place a large plate over the skillet and flip the tortilla onto the plate.
  11. Slide the tortilla back into the skillet, uncooked side down, and cook for another 5 minutes until golden and firm.
  12. Remove from heat and let cool for a few minutes before slicing.
  13. Serve warm, at room temperature, or cold.
