This is an impressive looking autumnal tart that is super easy to make. Don’t be tempted to skip the step where you cook the tart on a hot baking tray. This is really important to ensure a crispy base.

Serves 6

6 sheets of filo pastry

15g butter, melted

1 red onion, thinly sliced

3 sprigs of thyme, leaves picked

3 small sweet potatoes, peeled and sliced thinly lengthways

200ml freshly squeezed orange juice

120ml double cream

100g creme fraiche

3 medium eggs

large pinch of saffron

salt and pepper



Serves 6

100g fennel, finely chopped

20g coriander, finely chopped

1 red chilli, finely chopped

30ml olive oil

30ml freshly squeezed orange juice

15ml cider vinegar

salt and pepper


  1. Preheat the oven to 180’C and put a large baking try on the middle shelf to get hot. Grease a 24cm round, loose bottomed tart tin and dust with a little flour. Brush each pastry sheet with the melted butter and carefully line the tin, layering the pastry as you go and making sure there are no gaps anywhere. Set aside.
  2. Sauté the onions and thyme in a little olive oil for a few minutes only. Add the sweet potatoes and orange juice. Place a lid on the pot and simmer for 5 minutes. Remove the lid and simmer for another five minutes. Turn off the heat and carefully transfer the sweet potatoes to a plate to cool slightly.
  3. Soak the saffron in 1 tbsp boiling hot water. In a jug, whisk together the cream, creme fraiche, eggs, saffron water and the juice left over from cooking the sweet potatoes. Mix well and season.
  4. Arrange the sweet potatoes in the tart case and pour in the custard. Bake on the hot tray for about 30-40 minutes.
  5. To make the relish simply mix the ingredients together and season.
  6. When the tart is ready, serve topped with the relish.
