Instructions

  1. Preheat the oven to 200°C, 180°C fan, gas mark 6. Cut the onions into thin slices and place into a roasting tin. Add the Bertolli, sugar, vinegar, and thyme and season with salt and pepper. Mix well then spread out in an even layer. Roast in the oven for 30-35 minutes, stirring once or twice, until the onions become sticky and golden. Remove from the oven and mix in the olives.
  2. Increase the oven temperature to 210°C, 190°C fan, gas mark 7. Tip the onion mixture into a well-greased 22-24cm round, shallow cake or tarte tatin tin. Spread out evenly over the base.
  3. Unroll the pastry and cut a circle that is slightly larger than the top of the tin. Place the pastry over the onions and tuck it in around the sides like a blanket. Prick well with a fork to let the air escape and keep the pastry crisp.
  4. Bake for 15-20 minutes, or until the pastry is crisp and golden. Remove from the oven and run a knife around the edge to release the pastry. Place a large plate over the tin and invert the tarte onto the plate, shaking well to remove everything from the tin. Cut into wedges and serve with dressed salad leaves.
