Vegetarian mains
Leek and Parmesan tart
The secret of this recipe lies in cooking the leeks long and slow, so that they become sweetly caramelised. The rest takes no time at all and you can exercise your imagination adding extra toppings. Replace the Parmesan with another hard cheese to make this vegetarian.
Cook's notes
This recipe works equally well replacing the leeks with onions (or a mix of the two).
Ingredients
- 3–4 tbsp olive oil, or 50g butter
- 6 large leeks, washed, dried and thinly sliced
- bunch of thyme, tied with string
- 1 x 300g ready-rolled sheet all-butter puff pastry
- 25g Parmesan (or vegetarian equivalent), finely grated
- salt and black pepper
Method
-
Step 1
Heat the oven to 200°C/Gas 6. Heat the oil or butter in a heavy-bottomed saucepan and add the leeks and thyme. Slow-fry the leeks until they are very soft and starting to brown, a good 10–15 minutes.
-
Step 2
Cover the pan initially to help them sweat, then take off the lid halfway through so the liquid evaporates. Stir at intervals to stop them catching. Season with salt and pepper then cool.
-
Step 3
Meanwhile, lay out your pastry flat on a lightly greased non-stick baking sheet and bake for about 10 minutes until it has completely puffed up and is golden brown. (Check the bottom of the pastry is cooked too.)
-
Step 4
Flatten the pastry back down by covering it evenly with the leek mixture, leaving 5mm around the edge. Sprinkle with the Parmesan and any other toppings (see suggestions below) and return to the oven for a further 5 minutes, until the cheese has melted. Serve warm.
