Part 3/4:
The narrator takes a package of thawed puff pastry and cuts it into strips, creating a lattice crust that will be placed on top of the filling. Before baking, the puff pastry is brushed with melted butter, which the narrator says makes it even more delicious.
The pot pie is baked at 400°F for about 20 minutes, and then the remaining cheddar cheese is sprinkled on top. It goes back in the oven for another 5 minutes, until the crust is golden brown and the filling is bubbly.
