Chicken Broth (Best Option)
1 cup chicken broth per 1 cup beef brothChicken broth shares a similar savory profile with beef broth but is milder and more complementary to the chicken and vegetables in the pot pie. It provides the necessary umami and moisture to create a rich, flavorful sauce.
When substituting, use equal amounts and consider reducing added salt since chicken broth can sometimes be saltier. Taste the filling before final seasoning to avoid over-salting.
The final dish will have a slightly lighter flavor compared to beef broth but will remain rich and satisfying, preserving the classic comforting qualities of chicken pot pie.
