For the crust:
1/2 pound unsalted butter, at room temperature
1/2 cup granulated sugar
2 cups flour
1/8 teaspoon kosher salt
For the filling:
6 extra-large eggs at room temperature
3 cups granulated sugar
2 tablespoons grated lemon zest (4 to 6 lemons)
1 cup freshly squeezed lemon juice
1 cup flour
Confectioners’ sugar, for dusting
Preheat the oven to 350 degrees F.
You will start by making the crust, creaming the butter and granulated sugar together with an electric mixture until creamy. In a separate bowl combine the flour and salt and then add to the butter mixture until the consistency is lightly mixed. Dump the dough onto a well-floured board and gather into a ball. Flatten the dough with floured hands and press it into a 9 by 13 by 2-inch baking sheet, building up a 1/2-inch edge on all sides.
Bake the crust for 15 to 20 minutes, until very lightly browned. Take out of the oven and let cool. Leave the oven on.
To make the filling you will whisk together the eggs, sugar, lemon zest, lemon juice, and flour. Pour over the crust and bake for 30 to 35 minutes, until the filling is set. Let cool to room temperature. And then cut and dust with confectioners’ sugar.
