Steps

In a large mixing bowl, whisk together the flour and confectioners' sugar. Add the cold butter and use a pastry blender or your fingertips to work it into the flour mixture until it resembles coarse crumbs.
Gradually pour in cold water, stirring with a fork until the dough comes together. Wrap in plastic wrap and refrigerate for at least 30 minutes.
Preheat the oven to 375°F (190°C). Roll out the chilled dough on a lightly floured surface to a thickness of about 1/8 inch. Transfer to a tart pan with a removable bottom and trim the edges.
In a large skillet, cook the sliced onions over medium-low heat for 20-25 minutes, stirring occasionally, until they are dark golden brown and caramelized. Add the granulated sugar, balsamic vinegar, salt, and pepper, and cook for an additional 2 minutes.
Spread the caramelized onions evenly over the tart crust, leaving a 1-inch border around the edges. Sprinkle with crumbled goat cheese and chopped thyme.
Bake the tart for 35-40 minutes, or until the crust is golden brown and the filling is heated through.
Remove the tart from the oven and let it cool on a wire rack for at least 30 minutes before serving. Enjoy!
