Delicious courgettes add a tasty summer flavour to this Spanish omelette – easy to make with leftover potatoes. A light lunch or simple supper.
We had the umpteenth barbecue of the summer and I made rather too many of these fabulous smoky barbecue potatoes in foil. So the next day I came up with a plan to recycle them into a delicious Spanish omelette. It was super easy to make, quick, and very tasty. We ate it in the garden with a lovely summer salad.

All-in-one Spanish omelette
I love Spanish omelette – aka potato tortilla – because it’s basically a whole meal in one dish. Traditionally it’s made just with potatoes and eggs, but once you throw a few veggies in you’ve got your carbs, protein and vegetables all taken care of. It’s perfect for a light lunch or a simple supper, and you can even eat it cold. I was at a party once where they had little cubes of Spanish omelette on cocktail sticks to eat with drinks. Delicious!
I went for courgettes (zucchini) this time. Slicing them to the same thickness as the potatoes meant that everything could mix evenly and make nice layers in the omelette. The contrast between the super-soft courgette slices, the slightly denser potato, and the creamily-set egg was lovely.

No leftovers required!
It’s easy to make this Spanish omelette without the benefit of leftover barbecued potatoes. Simply slice and parboil your potatoes for 3-4 minutes, drain well, then fry in olive oil with a medium onion cut into wedges. Once the potatoes have started to brown and the onions are soft, tip them into a bowl and carry on as per the recipe below. It probably won’t add more than 10-15 minutes to the total recipe time.
Spanish Omelette
As you can see in the photos, we ate our Spanish omelette in the garden. A simple salad turned it into an al fresco summer feast!
This delicious Spanish omelette with courgette and potato served 2-3 as a main dish. It would go further as part of a buffet or alongside other dishes.

📖 Recipe

Spanish omelette with courgette & potato
Ingredients
- 2 medium courgettes (zucchini)
- 2-3 tablespoon olive oil
- 500 g leftover cooked sliced potatoes and onions SEE NOTES
- 5 large eggs
- 50 ml milk
Instructions
- Preheat the oven to 180°C (350°F).
- 2 medium courgettes, 2-3 tablespoon olive oilSlice the courgettes into 6-8mm (approx. ¼ inch) slices. Heat the olive oil in a large, heavy-based skillet that can go in the oven (i.e. no plastic handles etc). Cook the courgette slices for 3-4 minutes until starting to brown.
- 500 g (17 ⅔ oz) leftover cooked sliced potatoes and onionsAdd the leftover potatoes to the pan. Mix gently to avoid breaking up the vegetable slices. Cook for a few minutes, stirring occasionally to prevent sticking, until the potatoes are warmed through.
- 5 large eggs, 50 ml (⅕ cups) milkMeanwhile beat the eggs and milk together.
- Pour the egg mixture into the pan – it should just cover the vegetables. Cook on a very low heat for 5-6 minutes, then transfer to the oven and continue to cook for a further 10-15 minutes, until the eggs are set.
- Remove from the oven, run a knife around the edge of the tortilla, and invert onto a serving plate. Cut into wedges and serve.

Due to the provenance of the potatoes, I think I’ll be entering this into the No Waste Food Challenge! It’s hosted this month by Anne’s Kitchen, and organised by Elizabeth’s Kitchen Diary. And given that courgettes aren’t a traditional ingredient in a potato tortilla, I think it makes a good entry into the Extra Veg challenge too – Extra Veg is hosted by Nadine from JuggleMum, Helen from Fuss Free Flavours and Michelle from Utterly Scrummy.
