Step 1

Preheat oven to 200°C. Line 2 baking trays with non-stick baking paper. Place the tomato, cut-side up, on 1 lined tray. Drizzle over half the oil. Season with salt and pepper. Bake for 30-40 minutes or until the tomato softens.

Step 2

Meanwhile, heat the remaining oil in a large frying pan over medium heat. Add the onion and cook, stirring occasionally, for 10-15 minutes or until golden. Add the sugar and cook, stirring, for 2-3 minutes or until caramelised. Set aside to cool completely.

Step 3

Place the flour and butter in the bowl of a food processor and process until it resembles fine breadcrumbs. Add egg yolk and water, and process until the dough just starts to come together. Turn onto a lightly floured surface and knead until just smooth. Shape into a disc, cover with plastic wrap and place in the fridge for 30 minutes to rest.

Step 4

Roll out pastry on a lightly floured surface to a 32cm-diameter disc. Place on remaining lined tray. Spread caramelised onion over the pastry, leaving a 4cm border. Top with tomato and goats cheese. Fold in edges to partially enclose. Bake for 35-40 minutes or until the pastry is golden. Top with basil to serve.
