Cook the sausage in a large skillet over medium heat until browned, breaking it into smaller pieces as it cooks.
02 -
Sprinkle the flour over the cooked sausage, stirring it in, and cook for about 2 minutes. Gradually pour in the milk while stirring constantly. Increase the heat to medium-high until the mixture comes to a boil. Reduce the heat and simmer until the gravy thickens, about 5 minutes. Season with salt, pepper, and sage.

Preheat the oven to 190°C (375°F).

Roll out one sheet of puff pastry and line the bottom of a 9-inch pie dish, leaving some overhang around the edges. Pour the sausage gravy into the pastry-lined dish, spreading it evenly.
05 -
Roll out the second sheet of puff pastry and place it over the top of the sausage gravy. Trim any excess pastry and crimp the edges to seal. Cut a few small slits in the top crust to allow steam to escape.

Place the pie on the middle rack of the preheated oven and bake for 25-30 minutes, or until the pastry is golden brown and flaky.

Let the pie cool for a few minutes before slicing. Serve warm and enjoy.
