Method
- Heat a large frying pan with a glug of oil over a medium heat. Add the red onions and fry for 10 minutes, stirring occasionally. Add the sugar and cook for a further 10 minutes until sticky and caramelised.
- In a medium mixing bowl, beat the mascarpone with the lemon juice and zest, rosemary, spring onions and garlic. Season. Heat the oven to 200°C/180°C fan/gas 6.
- Unroll the pastry onto a baking sheet. Spread with the mascarpone, leaving a 2-3cm border. Top with the red onions, then the tomatoes and a little thyme. Drizzle over a little oil, season, then bake for 25 minutes. Turn the oven to 170°C/150°C/gas 3½. Bake for 20-25 minutes until the tomatoes have shrivelled and the pastry is golden. Replace any burnt thyme leaves with fresh and serve warm.
