Root vegetable tarte Tatin

6
60 minutes

Ingredients

  • 500g of puff pastry block
  • 1 large carrot, peeled and sliced into 1cm rounds
  • 1 large parsnip, peeled and sliced into 1cm rounds
  • 1 sweet potato, peeled and sliced into 1cm rounds
  • 1 banana shallot, peeled and sliced into rounds
  • 50g of butter
  • 1 tbsp of sherry vinegar
  • 1 tbsp of caster sugar
  • 3 sprigs of thyme
  • salt
  • freshly ground black pepper
  • plain flour, for dusting

Method

1
Place the vegetables in a large pan and add enough water to cover, season with salt and bring to the boil. Allow to simmer for 4–5 minutes, then quickly drain the vegetables and refresh in a bowl of iced water (this halts the cooking process and helps to retain their colours)
2
Drain the cooled vegetables and leave to dry on some kitchen towel
3
Preheat the oven to 200°C/gas mark 6
4
Roll out the puff pastry on a lightly floured surface. Using an ovenproof frying pan (approx. 25cm) as your guide, trim the pastry to a circle that is slightly bigger than the pan. Transfer to a baking tray lined with baking parchment and chill in the fridge
5
Place the frying pan on a medium-high heat and add the butter, vinegar and sugar, stirring until melted together. Reduce the heat slightly, and add the shallots – try to keep the rings intact by not moving them too much
6
Once they begin to soften and caramelise, scatter over the thyme leaves, shaking the pan gently to combine. Remove the pan from the heat and allow to cool for 5 minutes
7
Place the par-boiled vegetable rounds in a decorative pattern across the base of the pan, arranged like a mosaic with a mix of large and small pieces to fill the gaps. Make sure all the vegetables are coated in the butter glaze
8
Remove the pastry circle from the fridge and place on top of the vegetables in the pan. Gently tuck the edges in around the vegetables
9
Transfer the pan to the oven and bake for 20 minutes, then check the tarte to see if there is any excess butter or liquid bubbling up around the sides – if so, gently pour this away (you may need to use kitchen towel or a cloth to hold the tarte in place)
10
Reduce the oven to 180°C/gas mark 4 and return the tarte to the oven for a further 15–20 minutes, until the pastry has risen and is golden brown
11
Leave to cool for 10 minutes (the pastry will deflate slightly in this time), then place a plate over the top of the pan and carefully flip the pan over, so the tarte Tatin turns out on to the plate. Serve the tarte warm, perhaps with a fresh salad
