For the Filling:

Caramelize the Onions
In a large pan, sauté the onions over medium heat until golden. They should brown gradually over around 30 minutes. If needed, add a little more butter to help avoid burning.
As the onion is starting to brown, add the sugar, balsamic vinegar, and the salt. Continue to cook a few more minutes until the onions are deeply caramelized and the liquid has evaporated. Set aside.
Make the Pastry
In a large bowl, mix the flour and salt.
Cut in the butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs.
Add the milk and mix until the dough comes together.
Roll out the dough and line the bottom of a Pyrex dish or tart pan.
Beat the egg and brush it over the pastry.
Bake in a preheated oven at 375°F (190°C) for 10 minutes, until partially cooked.
Assemble the Tart
Evenly scatter the caramelized onions over the partially baked pastry.
Place goat cheese rounds on top of the onions.
Sprinkle with chopped rosemary.
Prepare the Custard
In a bowl, whisk together the egg, heavy cream, nutmeg, salt, and white pepper.
Pour the mixture over the onions and cheese in the tart.
