To make the pastry
Preheat the oven to 180 degrees C / 356 F.
Add the flour, butter, ¼ tsp of salt, 2 egg yolks and thyme leaves to a food processor and blend until you have a breadcrumb consistency.Slowly pour in the chilled water while blending and stop as soon as the dough comes together in a ball.Transfer the pastry to a board then shape into a thick disk, wrap in cling film then chill in the fridge for 30 - 60 minutes.
Roll out the pastry on a floured surface, it should be wide enough to generously cover a round 22 cm/9' ovenproof dish.Place the pastry onto the dish and gently push in the edges with your thumb. Roughly trim the edges leaving extra pastry for shrinking. Prick the pastry a few times with a fork. Place in the fridge for 10 minutes. Keep any leftover pastry for patching up any cracks.
Remove the pastry from the fridge. Place a round of parchment paper over the pastry and fill with baking beans. Bake in the top third of the oven for 15 minutes then take it out of the oven and remove the paper and beans. Check for any cracks and seal them up with the leftover pastry if needed. Bake again for 5 minutes. Remove from the oven and leave to cool a little.
For the filling
Place the beetroot on a baking tray add 1 tablespoon of olive oil, ¼ teaspoon each of sea salt and black pepper. Mix well then place on the top shelf of the oven and roast for 45 to 60 minutes, depending on the size of your chunks. The beetroot is done when it is soft. Remove from the oven and leave to cool.
In a skillet heat 1 tablespoon of olive oil over medium heat. Add the onions and cook slowly for about 15 minutes, until the onions are very soft. Once they are very soft turn up the heat slighlt then add 1 tablespoon of balsamic vinegar and stir well. Set aside to cool.
Beat the eggs and cream in a bowl and stir in the thyme leaves and ¼ teaspoons each of sea salt and black pepper.
To make the tart
Spread the red onions over the base of the tart, then spread the beetroot over the onions. Pour the egg and cream mixture over the beetroot then add the goat's cheese. Sprinkle over the walnuts.Place on the middle shelf of the oven and cook for 25 minutes, the tart is done when the top is golden brown and the filling should is cooked through. Remove from the oven, leave to cool for a few minutes then carefully remove it from the tin.
Serve hot or cold with a green salad.

Pastry, I use salted butter for my pastry and large free-range eggs. It's important to chill your pastry so don't skip that bit. You can leave out the thyme if you want.
Beets, go for small to medium sized beets, these are sweeter and more tender. Try and cut your beets into roughly the same size to ensure they cook at the same time.
Red onions, are really the best onion for this tart however you could use regular onions too. I would add a little brown sugar to those when you add the balsamic vinegar.
Cheese, goat's cheese is perfect in this tart. Look out for a creamy mild cheese. Sliced or crumbled is fine.
Cream, I use full fat double cream for this, I imagine a reduced fat cream would work well too.
