A Christmas essential
Works with red or yellow onions
1 Hour 15 Minutes
Heat oven to 180°C. Roll out the pastry onto a lightly floured surface and line a 23cm tart tin with it. Line with baking paper and fill with baking beans. Blind bake for 15 minutes.
Chop your onions into thin slices and grate your parmesan cheese.
Heat the butter and oil in a large pan and fry the onions on a low heat until pale (around 30 minutes).
In a bowl, beat the eggs and cream together. Then add the parmesan and season to your liking. Stir in the onions and spoon the mixture into the pastry case. Bake for 25-30 minutes until golden brown and slightly firm. Enjoy!
