   Combine the all-purpose flour and salt in a large bowl for the crust.

   约 1分钟

2. 2

   Cut the cold, cubed unsalted butter into the flour mixture using your fingertips or a pastry blender until pea-sized crumbs form.

   约 5分钟

   烹饪提示： Work quickly to keep the butter cold, which helps create a flaky crust.

3. 3

   Gradually add the cold water, mixing until the dough just comes together.

   约 2分钟

   烹饪提示： Do not overmix; stop as soon as the dough forms a ball.

4. 4

   Form the dough into a disc, wrap it in plastic, and refrigerate for at least 30 minutes.

5. 5

   Melt the unsalted butter in a large pan or Dutch oven over medium-low heat.

   约 2分钟

6. 6

   Add the thinly sliced yellow onion and a pinch of salt, then cook slowly, stirring occasionally, for 25-30 minutes until deeply caramelized and soft.

   约 25分钟

   烹饪提示： Cooking the onions slowly over low heat is crucial for developing their sweetness and rich flavor.

   Remove the caramelized onions from the heat and set aside to cool slightly.

   约 5分钟

    Carefully transfer the dough to a 24 cm (9.5-inch) tart pan with a removable bottom, pressing it gently into the sides.

    约 2分钟

11. 11

    Trim any excess dough from the edges.

    Let the tart rest for at least 15 minutes before slicing and serving.

    约 15分钟

    烹饪提示： This allows the filling to fully set and makes for cleaner slices.
