  • 3.   3. Preheat the oven to 180°C/350°F. Roll out the dough into a circle on a baking sheet lined with parchment paper. Spread the mixture onto the dough, leaving a 2 cm border. Place the sliced onions on top and fold the edges of the dough, pinching to create pleats. Bake for 30 minutes. Remove the tart from the oven, switch to the broil setting.
