This simple tart looks sensational and tastes as good as it looks – serve warm or cold for dinner or a summery lunch. Serves 4 for $13.


  • 2 (or) 3 red onions, thinly sliced

  • 1 tablespoon olive oil

  • 25 g butter

  • 1 tablespoon balsamic vinegar

  • 1 teaspoon brown sugar

  • 1 teaspoon wholegrain mustard

  • 1 teaspoon fresh thyme leaves (optional)

  • 1.5 frozen puff pastry sheets, thawed

  • 1 tablespoon capers (optional)

  • 0.33 cup black olives, pitted (optional)

  • 1 egg, lightly whisked

  • 150 g sliced ham, roughly chopped

  • 4 (or) 5 eggs, hardboiled

  • large handful rocket leaves


  • Place the onion, oil and butter in a large shallow saucepan. Cook over a gentle heat for 20 minutes until tender.
  • Mix in the balsamic vinegar, brown sugar, wholegrain mustard and thyme leaves, cook for a further 5 minutes. The onions should be a rich caramel colour, if not then cook a little longer. Set aside to cool.
  • Preheat the oven to 180°C.
  • Arrange the pastry end to end on a baking tray, pressing to join with a 1 cm overlap. Fold the pastry in to create a 1.5cm ridge around the outside.
  • Spread the onion over the pastry base, staying within the ridge. Scatter with capers and olives.
  • Brush the pastry edge witht the whisked egg.
  • Bake for 10 -15 minutes until the pastry is golden and puffed.
  • Halve or quarter the eggs and arrange on the warm tart along with ham and rocket leaves.

  • Rocket leaves offer an interesting peppery flavour on the top but you can also serve this with lettuce leaves alongside.
