Ingredients

Pastry

175g plain flour
Pinch of salt
40g butter
40g white vegetable fat

Filling

500g red onions, peeled
1 tbsp lemon juice
4 tbsp Filippo Berio Mild & Light Olive Oil
2 tsp fresh rosemary spikes, chopped
75g black olives, pitted and roughly chopped
3 medium eggs
284ml carton single cream
50g Gruyère cheese, grated

Method

To make the pastry, put the flour and salt into a bowl, add the fats and rub in to make a fine crumb texture. Add 3 tbsp cold water and mix with a flat bladed knife until the mixture forms a dough. Gather up and knead lightly on a floured surface until smooth.
Roll out, keeping a nice round shape, to line a 23cm diameter metal quiche tin, pricking the base with a fork. Place in the refrigerator for 30 minutes.
Meanwhile, slice the onions into thin wedges then place into a large bowl. Add the lemon juice and toss together. Heat the oven to 200°C/400°F/Gas Mark 6. Heat the Mild & Light Olive Oil in a large frying pan, add the onions and fry very gently for 15 minutes or until softened. Stir in the rosemary and allow to cool.
Line the pastry case with greaseproof paper and fill with baking beans, then bake for 10 minutes until beginning to colour around the edge. Remove the paper and beans and bake for a further 5 minutes. Remove from the oven and reduce the temperature to 180°C/350°F/Gas Mark 4.
Place half of the onions into the flan case and spread evenly then scatter over half of the olives and half of the cheese.
Beat the eggs with the cream, and season with salt and pepper. Pour three quarters over the onions then top with the rest of the onions, remaining egg mixture, olives and Gruyère cheese. Bake for about 20 minutes, or until lightly golden.

This Olive Oil is a healthy substitute for other cooking oils. With its high smoke point it is the ideal choice for frying, stir-frying and baking. The light bouquet allows the natural flavour of food to come through.
