Tortilla Española

This authentic Tortilla Española is a cornerstone of Spanish cuisine, celebrated for its simple yet deeply satisfying flavours. By slowly confitting waxy potatoes in olive oil and patience-testing the onions until they reach a rich, savoury sweetness, you create a texture that is both creamy and substantial. This vegetarian classic relies on high-quality ingredients to shine, making it a versatile dish that works beautifully for a rustic weekend brunch or as the centrepiece of a traditional tapas spread.

Traditionally served at room temperature, this Spanish omelettete is an excellent make-ahead option for picnics or light summer lunches. It is naturally gluten-free and packed with protein, offering a nutritious and comforting meal that pairs perfectly with a crisp green salad or a side of garlicky aioli. Whether enjoyed as a snack or a main course, it brings a genuine taste of the Mediterranean to your kitchen.

Ingredients for Tortilla Española

  • 550ml olive oil plus 1 tablespoon olive oil

  • 1 thinly sliced medium onion

  • salt

  • 2 peeled medium waxy potatoes, cut into 3/4" pieces

  • 8 large eggs

Heat 1 tablespoon olive oil in a large skillet over medium heat. Add 1 thinly sliced medium onion, season with salt, and cook, stirring occasionally, until softened and dark brown, 35–40 minutes; let cool slightly.

Meanwhile, heat 2 peeled medium waxy potatoes, cut into 3/4" pieces, in 475ml olive oil in a medium saucepan over medium-high heat until oil around potatoes begins to bubble. Reduce heat to medium and cook until potatoes are tender but have not taken on any colour, 10–12 minutes. Drain potatoes, reserving oil; season with salt and let cool slightly.

Using a fork, gently beat 8 large eggs with onion, potatoes, and 60ml reserved cooking oil in a large bowl.

Heat 45ml reserved cooking oil in a 10" nonstick skillet over medium heat (reserve remaining oil for another use). Add egg mixture and cook, lifting at edge and tilting skillet to let uncooked egg run underneath, until bottom and edge of tortilla are set but centre is still wet.

Set a large plate on top of skillet. Swiftly invert tortilla onto plate, then slide back into skillet, cooked side up. Cook until just set, about 2 minutes longer. Cut into wedges.
