One for the weekend, this dish takes a while to pull the separate elements together, but it is well worth the effort. This is a really tasty dish with lots of colour and flavour. Serve with some crusty bread and green leaves.

Serves: 6 people
Ingredients
- 3 large courgettes
- Couple glugs of olive oil
- 4 medium leeks – halved lengthways and very thinly sliced
- finely grated zest of 1 lemon
- 1 x 28g pack fresh basil, leaves shredded, a few reserved to garnish
- 65g pine nuts
- 2 x 250g pack fresh lasagne sheets
- 3 x 350g tubs fresh tomato & basil pasta sauce
- 3 x 125g mozzarella, drained and torn into small pieces
- 50g Gruyère, or vegetarian alternative, grated
Method
- Firstly, set the oven function, temperature, and oven shelf. Set the function to “fanned” and the temperature initially to 190°. The oven shelves can be in any position inside the cavity.
- Trim the ends of the courgettes, then holding the courgette lengthways cut them into long slices around 3mm thick.
- Arrange the slices on lined baking trays, in a single layer, and brush with olive oil.
- Season, then bake for 10-12 minutes but turn halfway through, until tender and starting to go golden at the edges. Remove and set aside to cool.
- Turn the oven down to, fan 180°C.
- Heat a glug of oil in a large frying pan, add the leeks and fry on a low to medium heat, stirring regularly, until tender and soft, about 10 minutes.
- Allow to cool, then stir in the lemon zest, half the basil and 45g pine nuts.
- Cut each lasagne sheet into three strips, each about 5cm wide. Place in a large bowl and cover with cold water. Leave to soak for 5 minutes.
- Mix the rest of the basil with 2 tubs of tomato sauce then spread this over the base and up the sides of a roasting tin or baking dish, approx 25 x 15cm.
- Shake the water from 6 pasta strips and line up on a chopping board or clean worktop. Spread a generous teaspoon of the remaining tomato sauce over each strip, then lay a courgette slice on top. Take a third of the leek mixture and scatter it over the courgettes, then place a piece of mozzarella at the end of each strip. Roll up tightly from the mozzarella end, and place in the baking dish, nestling them together snugly. Repeat, in batches of 6 until all the courgettes have been used up. Brush the tops of the rolls with a little oil and cover the dish tightly with oiled foil.
- Bake for 35-40 minutes, until the pasta is tender in the middle and crisp at the edges. Remove the foil, sprinkle over the rest of the pine nuts and grated cheese; grill for a few minutes to melt the cheese and toast the pine nuts. Scatter with extra basil.
Cooks notes
- The oven shelf can be in any position inside the cavity. This is because you are using the fanned function which distributes the heat evenly throughout the oven cavity.
- You could make your own tomato and basil sauce by using 2 tins of chopped tomatoes, some garlic, dried basil, glug of live oil and tomato puree and then simmering for 20 min.
