📝 About This Recipe

A cornerstone of Spanish cuisine, this thick, soulful omelet relies on the humble magic of slow-confited potatoes and onions in golden olive oil. Unlike a French omelet, the Tortilla Española is dense, hearty, and incredibly versatile, offering a creamy, melt-in-your-mouth interior and a perfectly bronzed exterior. Whether served as a tapa in a bustling Madrid bar or a family dinner at home, it is a timeless celebration of simple, high-quality ingredients.

🥗 Ingredients

The Base

  • 1.5 lbs Yukon Gold or Kennebec Potatoes (peeled, halved lengthwise, and sliced into 1/8-inch thick semi-circles)
  • 1 large Yellow Onion (thinly sliced)
  • 2 cups Extra Virgin Olive Oil (high quality, for poaching the potatoes)

The Custard

  • 6-8 pieces Large Eggs (depending on size, at room temperature)
  • 1.5 teaspoons Kosher Salt (plus more for the potato soak)
  • 1/4 teaspoon Black Pepper (freshly cracked)

For the Garnish & Serving

  • 1 pinch Flaky Sea Salt (for finishing)
  • 1 tablespoon Fresh Parsley (finely chopped for color)
  • 1 loaf Crusty Baguette (sliced for serving)
  • 1/2 cup Garlic Aioli (optional, for dipping)

👨‍🍳 Instructions

  1. 1

    Prepare your potatoes and onions. Ensure the potato slices are uniform in thickness (about 1/8 inch) so they cook evenly. Pat them dry with a paper towel to remove excess moisture.

  2. 2

    In a 10-inch non-stick skillet, heat the olive oil over medium heat. To test if it's ready, drop one potato slice in; it should gently bubble, not sizzle aggressively.

  3. 3

    Carefully add the potatoes and onions to the oil. The oil should almost completely cover them. Reduce heat to medium-low.

  4. 4

    Poach the vegetables for 15-20 minutes. You are not frying them to a crisp; you want them tender and translucent. Stir occasionally with a slotted spoon so they don't stick.

  5. 5

    While the potatoes cook, crack the eggs into a large mixing bowl. Add the salt and pepper, and whisk gently until just combined—do not over-beat to avoid too much air.

  6. 6

    Once the potatoes are fork-tender and the onions are sweet, drain the mixture through a colander set over a heat-proof bowl. Save that delicious infused oil for future cooking!

  7. 7

    Immediately add the hot potato and onion mixture into the beaten eggs. This is the secret step: let it sit for 15 minutes. The heat from the potatoes partially cooks the eggs, creating a creamy 'panada'.

  8. 8

    Wipe out your skillet and add 1-2 tablespoons of the reserved potato oil. Heat over medium-high until the oil is shimmering.

  9. 9

    Pour the egg and potato mixture into the pan, spreading it out evenly. Lower the heat to medium.

  10. 10

    Cook for about 2-4 minutes. Use a spatula to run around the edges, tucking them in to create a rounded shape. Shake the pan occasionally to ensure the bottom isn't sticking.

  11. 11

    The Flip: When the edges are set but the center is still slightly runny, place a large flat plate over the skillet. In one confident motion, invert the pan so the tortilla lands on the plate.

  12. 12

    Slide the tortilla back into the pan, raw side down. Use your spatula to tuck the edges under again to maintain that iconic puck shape.

  13. 13

    Cook for another 2-3 minutes. For a traditional 'juicy' interior, the center should feel slightly soft when pressed. For a firm tortilla, cook for 5 minutes.

  14. 14

    Slide the finished tortilla onto a clean serving plate. Let it rest for at least 15 minutes before slicing; this allows the internal structure to set.

  15. 15

    Garnish with flaky sea salt and parsley. Slice into wedges or cubes and serve warm or at room temperature.

💡 Chef's Tips

Don't skimp on the olive oil; it's the primary flavoring agent for the potatoes and can be reused for sautéing later. The resting period (Step 7) is non-negotiable for an authentic texture; it allows the potatoes to absorb the egg. Use a high-quality non-stick pan to ensure the flip is successful and the tortilla doesn't tear. If you prefer a 'Tortilla Paisana', you can add diced chorizo or red bell peppers to the poaching stage. Avoid browning the potatoes; the goal is a pale, tender confit rather than a crispy fry.

🍽️ Serving Suggestions

Serve at room temperature with a side of homemade Garlic Aioli or Romesco sauce. Pair with a glass of chilled Spanish Albariño or a dry Manzanilla Sherry. Accompany with a simple green salad dressed in a sharp lemon vinaigrette to cut through the richness. Serve as 'Pincho de Tortilla'—a wedge perched atop a slice of baguette secured with a toothpick. Add a side of 'Pan con Tomate' (toasted bread rubbed with garlic and fresh tomato pulp).
