A celebration of Spring vegetables – overlapping layers of soft, caramelised leeks and asparagus, creamy peas and mascarpone, encased in layers of golden, flaky puff pastry.
Ingredients
• 500g of puff pastry
• 250g of baby leeks, trimmed
• 250g of asparagus, trimmed to the same length as the leeks
• 1 garlic clove, finely chopped
• 100g of peas, fresh or frozen
• 150g of mascarpone
• 25g of tarragon, finely chopped
• 25g of flat-leaf parsley, finely chopped
• 1/2 lemon
• 50g of butter
• 1 egg, beaten for glazing
• plain flour, for dusting
• salt
• freshly ground black pepper
Method
Take the puff pastry out of the fridge and allow to come to room temperature while making the filling.
Place the butter in wide saucepan and melt over a medium heat. Add the baby leeks and reduce the heat a little, slowly frying the leeks in the butter for 5–6 minutes.
Add the asparagus and continue to cook for another 10 minutes, stirring occasionally – the aim is to soften and slightly caramelise the vegetables.
Toss in the garlic right at the end and cook for another minute, then remove the pan from the heat and set aside.
Meanwhile, bring a small pan of water to the boil and quickly blanch the peas for a minute. Drain and leave to cool until required.
Once cool, mix the peas with the mascarpone, chopped tarragon and parsley. Finish with a good squeeze of lemon juice and season well with salt and pepper.
Preheat the oven to 200°C/gas mark 6. Divide the puff pastry into two and roll out each piece on a lightly floured surface to create 2 circles – a 23cm circle and a slightly larger 25cm circle (you could use large plates as a guide). Place the smaller circle on a baking tray lined with baking parchment.
Halve the leeks and asparagus and arrange the pieces to form a circle in the centre of the smaller disc, leaving a 2cm border around the edge – try to alternate the pieces to give an even spread.
Continue stacking the vegetables in overlapping circles until all used up, then mound the pea and mascarpone mixture over the top. Brush some of the beaten egg around the pastry border and drape the larger disc of pastry over the top of the vegetables. Press the edges together firmly to seal.
Decorate the top of the pastry by using a sharp knife to lightly score curved lines outwards from the centre, starting from the top of the pie and curving down to the bottom. Repeat all the way around. Brush the remaining egg over the whole dome to glaze and make a small hole in the centre to allow steam to escape.
Place the baking tray in the oven and bake for 30–35 minutes, until golden and glorious.
