Serves 4-6, Preparation time 10 mins, Cooking time 40 mins
- 800 g red onions
- 50 g Provolone cheese
- 320 g puff pastry
- 3 dessert spoons of sugar
- 1 spoon of white vinegar
- 20 g unsalted butter
- 1 egg
- Provolone cheese, to taste
Method
Finely slice the onions, then put them in a pan with butter and let them simmer for about 10 min, then add sugar and cook over a low heat for about 20 mins, stirring from time to time by adding a spoon of white vinegar and let it evaporate by turning up the heat.
As soon as they are ready, let them cool down a bit.
Beat the egg along with a bit of water.
Dice the Provolone and set aside.
Preheat oven to 180C. Unroll puff pastry dough and place it on a parchment lined baking sheet. Cut a 2cm border around the edge of the pastry and glaze its edge with beaten egg.
Prick with a fork the bottom of the puff pastry so it won’t swollen during baking, add caramelised onions and sprinkle diced Provolone over them.
Bake for 15-20 mins to 180 C or until the pastry is golden brown and Provolone melts.
