In a medium bowl, add the flour and powdered sugar.

Chop the butter into small chunks and mix it together with the combined flour and powdered sugar.

Using your hands, knead the ingredients lightly together, just until combined.

In a separate bowl, whisk together the egg, salt, vanilla, and lemon zest.

Add the mixture to the dough, and using your hands, form the dough into a ball.

Don't overwork the dough, knead it just enough to combine the ingredients together.

Once the dough is made, wrap it in a plastic foil and place it in the refrigerator for at least 30 minutes.

Preheat the oven to 350° Farenheit or 180° Celsius.

Prepare a pie baking dish by greasing it lightly with butter or sunflower seed oil.

Remove the cooled dough from the fridge. Using kitchen foil, place one piece on the bottom of the dough and the other piece on top of the dough to prevent the dough from sticking to the counter when you're rolling it out.

Roll out the dough until you obtain a large circle.

Place the rolled out dough onto the pie baking dish and using your finger tips, gently press the dough into the dish.

Remove any overflowing edges and use the extra dough for framing your pie later on.

If you want to prevent getting a soggy crust or, ensure the crust is fully baked, slightly pre-bake (blind bake) your pie crust. Take a piece of parchment paper and place it on top of the dough that's laid out inside the baking dish. Weigh it down with some rice or beans, then bake it at 350° Fahrenheit or 180° Celsius for about 15-20 minutes, depending on how thick is your crust.

Take it out of the oven. Remove the parchment paper and the weights, and pour the pumpkin filling inside the pre-baked crust.

Frame it with the leftover dough by rolling it with your hand into a thin long strand. Then line it on top of the filling along the edge of the pie dish. Use a fork to add a pattern by gently pressing it into the dough.

Bake your pie for 45-55 minutes maximum, depending on your oven.

Take it out and cool it off for 15-20 minutes. Then enjoy your freshly baked pumpkin pie with a scoop of ice cream or some whipped cream.
