Classic Spanish Tortilla (Tortilla Española)

Tortilla Española, or Spanish tortilla, is a simple but iconic dish made from eggs, potatoes, and onions. Unlike a Mexican tortilla, this is a thick, hearty omelet enjoyed throughout Spain as a tapa, snack, or light meal, and it’s just as delicious warm or at room temperature.

Description

This recipe slowly cooks thinly sliced potatoes and onions in olive oil until tender, then combines them with beaten eggs and cooks the mixture into a thick, golden tortilla. The result is a comforting, custardy dish with crisp edges and a soft, flavorful center.

Equipment Needed

  • Large nonstick skillet
  • Large plate (for flipping)
  • Slotted spoon
  • Mixing bowl

Ingredients

  • 6 large eggs
  • 4 medium potatoes, peeled and thinly sliced
  • 1 onion, thinly sliced
  • 1 cup olive oil
  • Salt to taste

Ingredient Notes: Slicing the potatoes thin and uniform ensures even cooking. Waxy potato varieties hold their shape better than starchy ones like russets.

How to Make It (Preparation)

  1. Heat the olive oil in a large skillet over medium heat. Add the potatoes and onion, cooking slowly until soft but not browned, about 15-20 minutes, stirring occasionally.
  2. Remove the potatoes and onion with a slotted spoon, draining well, and reserve a small amount of the cooking oil. Let cool slightly.
  3. In a large bowl, whisk the eggs with salt, then gently fold in the potatoes and onion until evenly coated.
  4. Heat a small amount of the reserved oil in a nonstick skillet over medium-low heat.
  5. Pour in the egg mixture, spreading it evenly, and cook for about 5 minutes, until the edges begin to set.
  6. Place a large plate over the skillet and carefully invert the tortilla onto it.
  7. Slide the tortilla back into the pan to cook the other side for another 4-5 minutes, until just set in the center.
  8. Slice into wedges and serve warm or at room temperature.

Pro Tips for Success

  • Cook the potatoes low and slow so they become tender without browning or crisping.
  • Let the potato mixture cool slightly before adding to the eggs to avoid scrambling them.
  • Use a nonstick skillet to make flipping the tortilla much easier.
  • For a firmer tortilla, cook a minute or two longer on the second side.

Variations & Substitutions

  • Tortilla with peppers: add sautéed bell peppers to the potato mixture.
  • Chorizo tortilla: mix in diced, cooked chorizo for extra flavor and protein.
  • Lighter version: reduce the amount of olive oil used to cook the potatoes.

Storage & Reheating

Store leftover tortilla covered in the refrigerator for up to 3 days. Serve cold or at room temperature, or gently reheat individual slices in a skillet over low heat. This dish is traditionally enjoyed cold as a tapa the next day.

Health Benefits

Eggs are a complete protein source, providing all essential amino acids along with choline, which supports brain health. Potatoes contribute potassium and fiber, especially when the skin is retained. Cooking with olive oil, a staple of the Mediterranean diet, adds beneficial monounsaturated fats linked to heart health.

Frequently Asked Questions

Why did my tortilla fall apart when flipping?
This usually happens if the eggs haven’t set enough on the first side. Cook a bit longer before attempting to flip, and use a large plate for support.

Can I use less oil?
Yes, while traditional recipes use a generous amount of oil to gently poach the potatoes, you can reduce it and cook the potatoes covered over low heat instead.

Is Spanish tortilla served hot or cold?
Both are traditional; it’s commonly served warm right after cooking or cold the next day as a tapa.
