This courgette potato tortilla is a wonderful vegetarian take on the classic Spanish omelette, offering a lighter texture and a delicate, savoury flavour. By slowly softening the potatoes and onions in olive oil alongside grated courgette, the vegetables become incredibly tender and sweet before being set in a golden, protein-rich egg base. It is a rustic and comforting dish that celebrates simple, high-quality ingredients.
Perfect for a weekend brunch or a light midweek supper, this versatile tortilla also makes an excellent addition to a picnic basket or a tapas spread. Because it is equally delicious served warm or at room temperature, it is a brilliant make-ahead option for busy households. Enjoy a generous wedge alongside a crisp green salad and a dollop of creamy soured cream or garlicky aioli.

Ingredients for Courgette Potato Tortilla
900g courgette (preferably small
6 to 8)
900g boiling potatoes
350ml olive oil
600ml chopped Spanish onion (450g )
10 large eggs
a 12-inch nonstick skillet
How to make Courgette Potato Tortilla
Coarsely grate courgette, then toss with 2 teaspoons salt and let stand 30 minutes.
While courgette stands, peel potatoes and cut into 1/3-inch dice.
Heat oil in skillet over medium-high heat until hot, then add potatoes, onion, and 3/4 teaspoons salt. Reduce heat to medium-low and cook (without browning), uncovered, stirring occasionally, 30 minutes.
Transfer courgette to a colander to drain, then squeeze small handfuls to remove as much liquid as possible, transferring as squeezed to a small bowl.
Add courgette to potatoes and cook, stirring occasionally, until potatoes are tender and courgette is slightly browned, about 15 minutes. Drain vegetables in colander set over a bowl, reserving oil. Cool 5 minutes.
Lightly beat eggs in a large bowl, then stir in vegetables, 1 tablespoon reserved oil, 3/4 teaspoons salt, and 1/2 teaspoons pepper.
Return 1 tablespoon reserved oil to skillet and add egg mixture, pressing potatoes flush with eggs. Cook over low heat, covered, until almost set and underside is golden, 12 to 15 minutes. Remove from heat and let stand, covered, 15 minutes.
Run a rubber spatula around tortilla and shake skillet gently to loosen (if bottom sticks, carefully slide spatula underneath). Slide tortilla onto a large flat plate, then cover with skillet and invert tortilla back into skillet. Round edge of tortilla with rubber spatula and cook over low heat, uncovered, until set, about 15 minutes more.
Slide tortilla onto a serving plate and cut into wedges. Serve warm or at room temperature.
