Preheat your oven to 375°F and prepare a 9×13 casserole dish with non-stick cooking spray.
In a large bowl, combine the shredded chicken, carrots, peas, corn, and potatoes.
Stir in the cream of chicken, cream of celery, minced garlic, onion powder, Italian seasoning, black pepper, and heavy cream until well combined.
Spread the mixture evenly along the bottom of your casserole dish and place your pizza crust over the mixture. You may need to gently stretch your pizza dough slightly to cover the pot pie mixture completely.
Using a fork, tuck the sides of the pizza dough down along the sides of the casserole dish.
In a small bowl or cup, combine the garlic powder with the melted butter and lightly brush it over the pizza dough, making sure not to miss any spots.
Bake the casserole uncovered for 30 minutes or until the top is golden brown and the filling is heated throughout.
Serve warm.
