First, take one crust from the package and line your pie plate. If it feels too stiff, let it sit at room temperature for 10 minutes so it's easier to shape. Gently trim any excess dough along the edges. Having a well-fitted crust helps hold your filling without gaps or overhangs.
In a bowl, stir together the thawed vegetables, shredded chicken, cream of potato and chicken soups, milk, and seasoning salt until everything is evenly coated. The milk ensures the mixture isn’t too thick, while the soups give that creamy, rich base. Taste it—adjust salt or add pepper if needed—so your flavors are balanced before going into the pie crust.
Pour the filling into your prepared bottom crust. Lay the second crust on top, pressing the edges to seal—pinch or flute them for a decorative touch. Slice small vents in the top crust so steam can escape and prevent sogginess. This little step helps ensure a flaky, crisp finish.
Preheat your oven to 375 °F. Place the assembled pie in the center and bake for 45 to 50 minutes, until the crust is golden brown and the filling bubbles at the vents. If the edges brown too quickly, loosely tent them with foil near the end. Once done, let the pie rest for 10 minutes before slicing to allow the filling to set up.
