Asparagus, caramelised onion and Gorgonzola puff tart

Serves: 6
Cooking Time: 45 minutes

Ingredients

  • 1 x 400g roll puff pastry, thawed
  • 1 egg, beaten
  • 40g butter
  • 4 large onions, thinly sliced
  • 30ml (2 tbsp) brown sugar
  • 30ml (2 tbsp) balsamic vinegar
  • salt and freshly ground black pepper, to taste
  • 400g fresh asparagus, trimmed and blanched
  • olive oil, to brush
  • 75g Gorgonzola
  • handful microherbs, to garnish

Instructions

1

Preheat the oven to 200°C and line a large baking tray with baking paper.

2

Transfer the pastry onto the prepared tray. Using a small knife, score a 1cm border around the edge of the pastry, making sure you don’t cut all the way through the base. Prick the base all over with a fork, brush the edges with the beaten egg and bake until puffed and golden, 10 – 12 minutes. Remove from the oven and set aside.

3

Meanwhile, melt the butter in a large heavy-based saucepan over low-medium heat. Add the onions and cook, stirring occasionally, until soft and lightly browned, 15 minutes. Add the sugar and vinegar and cook, stirring, until sticky and caramelised, about 5 minutes. Remove from heat, season and set aside.

4

To assemble the tart, spread the caramelised onions on the base of the tart. Arrange the asparagus spears in a single layer over the caramelised onions, alternating ends and tips. Brush with oil and season. Crumble the Gorgonzola on top and bake until the cheese has melted, about 8 minutes.

5

Scatter the tart with microherbs before serving.
