Can I make these ahead of time?
Yes. Assemble the pot pies, cover with plastic wrap, and refrigerate up to 24 hours. Add 2–3 minutes to baking time if baking from cold.
What can I use instead of rotisserie chicken?
Shredded cooked chicken breast, canned chicken (drained), or leftover roasted chicken work equally well.
Can I freeze these pot pies?
Freeze unbaked pot pies on a tray, then transfer to freezer bags. Bake from frozen, adding 5–8 minutes to the cooking time.
What vegetables can I add beyond frozen mixed?
Diced fresh carrots, celery, peas, corn, or spinach all work. Chop finely and stir into the filling before assembling.
