- 1 onion, sliced
- 3 garlic cloves, sliced
- 200 g of chestnut mushrooms, sliced
- 15 g of hazelnuts, roughly chopped
- 2 tbsp of flat-leaf parsley, chopped
- 150 ml of double cream
- 150 ml of semi-skimmed milk

Method
Step 1
For the pastry, mix the flour, butter and sea salt in a food processor (or by hand) to a crumb-like texture. Trickle in 50ml chilled water, mixing until it all comes together in a dough. Knead briefly, then wrap and chill for 30 mins.Step 2
Preheat the oven to 200°C/180°C fan/gas 6. Put the artichokes in a roasting tin with the thyme and oil. Season and roast for 30 mins, turning once. Add the onion, garlic, mushrooms and hazelnuts and roast for 20 mins more or until tender, turning halfway for even cooking. Remove from the oven and scatter over the parsley.Step 3
Meanwhile, roll out the dough large enough to line a 20cm loose-bottomed, fluted tart tin, with an overhang. Prick the base, line with baking paper and baking beans (or rice) and bake for 20 mins. Remove the beans (or rice) and paper; return to the oven for 5 mins, or until the base is dry and lightly coloured. Remove from the oven and trim the overhang.Step 4
For the custard, whisk the cream, milk, eggs and egg yolk in a large jug to combine; season well.Step 5
Fill the tart case with the veg mixture, then crumble over the cheese. Pour in the custard and bake for 30 mins, or until golden. Leave to rest for 20 mins before serving with a mixed salad, if you like.
