Tomato and ricotta tart

Method

1. Preheat the oven to 220°C/fan 200°C/gas 7 with a baking sheet inside. Melt the butter in a pan, add the onions, season and cook gently for 10 minutes or until starting to turn golden. Add the garlic and cook for 2-3 minutes more. Cool slightly.
2. Unroll the pastry and spread the cooled onion mix over, leaving an uncovered border of about 1cm. Dollop on the ricotta, then top with the tomatoes. Season well, then drizzle with olive oil. Transfer the tart to the hot baking sheet and bake for 15-20 minutes until the pastry is puffed and golden and the tomatoes are soft and juicy. Remove from the oven and leave to cool for 5 minutes. Drizzle over a little more oil, sprinkle with thyme, then serve.
