A from-scratch chicken pot pie with a buttery, flaky crust and a rich, creamy chicken-and-vegetable filling. Cozy, make-ahead friendly, and flexible with simple substitutions.
Make-ahead: Chill dough up to 2 days; filling can be refrigerated 2 days or frozen 3 months. Reheat leftovers at 350°F until warmed through. For a double crust, blind bake the bottom 12–15 minutes. Rotisserie chicken can replace seared chicken. Keep dough cold, vent the top, and let filling cool slightly before assembly to avoid sogginess.
