Presenting one of the easiest, tastiest renditions of pot pie you'll ever encounter, with a crust made entirely from stuffing that remains crisp even when it hits the rich and creamy chicken filling. If you'd like to shave off minutes, go ahead and start with boxed stuffing mix and rotisserie chicken (we won't tell).
Brush the bottom and sides of a 10-inch heavy skillet, preferably cast-iron, with 1 tablespoon butter. Mix together the stuffing and chicken broth in a bowl, then press the stuffing mixture into the bottom and up the sides of the skillet in an even layer, occasionally dipping your hands in cool water if necessary to help prevent the stuffing from sticking. Bake until dry to the touch and lightly browned, 15 to 20 minutes.
Whisk together the condensed soup and cream cheese in a large bowl until smooth. Stir in the chicken and vegetables. Pour the filling into the crust.
Toss the sweet potato slices with the remaining 4 tablespoons butter in a bowl. Sprinkle with salt and pepper and toss again. Arrange the slices on top of the pot pie in concentric circles.
Bake until the sweet potato slices start to curl and brown around the edges, 45 to 50 minutes. In the last 5 minutes, top the pot pie with the sage leaves. Let rest 10 minutes before slicing and serving.
