Preheat the oven to 350°F (175°C).

In a bowl, combine the flour, butter, sugar, and salt to create the crust. Press the mixture into the bottom of a tart pan.

Bake the crust for 10 minutes, then remove from the oven and let it cool slightly.

In another bowl, whisk together the blueberries, lemon juice, eggs, heavy cream, and lemon zest until well combined.

Pour the blueberry mixture into the cooled crust.

Bake the tart for an additional 40 minutes or until the filling is set.

Allow the tart to cool, then dust with powdered sugar before serving.
