Instructions
Pastry Dough
Whirl dry ingredients for crust in the bowl of a food processor. Add half the butter and process until you no longer see chunks. Add remaining butter and process briefly, leaving chunks the size of peanuts.
Working quickly, turn on the food processor and pour the ice water through the feed tube, stopping before the dough comes together. Pinch a bit of the dough between your fingers. If it does not stick together, add a couple of teaspoons more water and whirl briefly.
Turn out the dough onto a large piece of plastic wrap. Use the plastic wrap to help you create a large, flat disk: fold the edges of the dough toward the center and press down to smooth out the roughness. Refrigerate dough for at least 30 minutes.
Tart Filling and Assembly
Preheat oven to 375° F.
Heat olive oil over moderate heat in a large, heavy skillet. Add onions and ½ teaspoon salt, stirring to combine. Cook, covered, until softened, about 20 minutes, lifting the lid occasionally to stir.
Remove the lid and continue cooking, stirring occasionally, until the onions are pale golden and any remaining liquid evaporates. Remove skillet from heat to cool onions slightly.
Roll out the dough into a 14-inch circle. Transfer the dough to a 12-inch tart pan with a removable bottom. Fold the overhanging edge down inside the tart pan, pressing gently to help it adhere.
Spread onions over the dough and top with cheese. Arrange tomato wedges in concentric circles over the cheese. Season with salt and pepper.
Bake in preheated oven heated until the crust is golden, about 50 to 60 minutes. Serve warm or at room temperature.
