Recipe
Make Spanish omelette (tortilla espanola) at home
Ingredients
- 1 lb (450 g) waxy potatoes, peeled and thinly sliced
- 1 medium onion, thinly sliced
- 1 cup (240 ml) olive oil for frying
- 6 large eggs
- 1 1/2 tsp salt
How it's made
- Heat the oil in a deep skillet over medium-low heat.
- Add potatoes and onion with a pinch of salt and cook gently for 20 to 25 minutes until very tender but not browned.
- Drain in a colander, keeping a tablespoon of the oil.
- Beat eggs in a large bowl with the rest of the salt, stir in the warm potatoes and onion, and let sit 10 minutes.
- Heat a little oil in a 9-inch non-stick skillet, pour in the mixture and cook on medium-low 4 to 5 minutes until the edges set.
- Place a plate on top, flip the pan over, and slide the tortilla back in to cook the other side about 3 minutes.
- Rest a few minutes, then slice into wedges.
Variations
- With onion: the classic version most people argue is best.
- Without onion: potatoes and eggs only.
- Added extras: peppers, chorizo or zucchini.
Cook’s tip: Keep the center slightly juicy by not overcooking the second side.
