Deep 23cm loose-bottomed tart tin

To make the pastry, put the flour, butter, salt and thyme into a food processor and process until the mixture looks like fine breadcrumbs. Add one whole egg and the egg yolk along with 3 tbsp milk, then pulse until the dough comes together. Shape the pastry into a disc, wrap in cling film and chill for at least 1 hour.

For the filling, heat the grill to high. Heat a large pan over a medium-high heat and add a good drizzle of oil. Fry the sliced onions, stirring every now and then, for 15-20 minutes or until soft and golden. Transfer to a tray to cool. Meanwhile, lay the bacon on a baking tray and grill until crisp )10-12 minutes). Transfer to a board and cut into small pieces.

Heat the oven to 190°C/170°C fan/ gas 5. Roll out the pastry on a lightly floured surface to the thickness of a £1 coin and use it to line the tart tin. Line the pastry case with non-stick baking paper and fill with baking beans or rice. Chill for 15 minutes.

Bake the chilled pastry case for 25 minutes, then lift out the paper and beans/rice. In a small bowl, beat the remaining egg and 2 tbsp milk and brush all over the inside of the case. Return to the oven for 10-12 minutes until golden, then set aside. Turn the oven down to 160°C/140°C fan/gas 3.

In a bowl, lightly beat together the 3 eggs, cream, milk, parsley and half the cheese. Season with salt and pepper. Scatter the fried onions, spring onions, bacon and pickled onions into the pastry case. Put the tin on a baking sheet, then carefully pour the egg mixture into the pastry case and sprinkle with the remaining cheese. Bake for 35 minutes or until the quiche is softly set. Cool until warm before removing it from the tin.
