How to Make Onion and tomato tart Recipe?
Credit by: KingOfChef
Heat oil in a frying pan over medium-low heat. Add onions. Cook, stirring occasionally, for 15 minutes or until light golden. Add sugar and season with salt and pepper. Cook for 5 minutes. Set aside to cool.
Preheat oven to 200°C. Line 2 baking trays with baking paper. Cut each pastry sheet in half. Layer 2 pastry halves together, pressing gently to secure. Repeat with remaining pastry. Place pastry rectangles on prepared trays.
Lightly score a 2cm border in pastry rectangles, but do not cut all the way through
Divide caramelised onions between pastry rectangles. Spread to the border. Top with tomatoes, olives and basil. Bake for 30 minutes, swapping trays over in oven after 15 minutes or until pastry is crisp, puffed and golden. Serve.
Scoring pastry: Scoring the top pastry sheet forms the border for the tarts. Don't cut all the way through, as the border and centre pastry separate during cooking. Keep food inside the border as this holds centre of pastry down, allowing edges to puff.
