You can reheat a chicken pie in the microwave and it's best to cut the chicken pie into slices and reheat the chicken pie slices individually so the chicken pie heats up without overcooking it.
However it's better to reheat the chicken pie in the oven as it will heat up much better without burning it or it becoming hard.
Chicken Pot Pies reheat better in the microwave than regular chicken pies do but either of them can be reheated in the microwave although the oven is much better.
A chicken pot pie will last up to 5 days in the refrigerator and up to 6 months in the freezer.
The best way to reheat a chicken pot pie or any other pot pie is to reheat the chicken pot pie in the oven.
Preheat your oven to a temperature of 300 F and cover the edges of your chicken pot pie with foil such as tin foil or aluminum foil to avoid burning the crust of the chicken pot pie.
Heat the chicken pot pie in the oven at 300 F for around 15 minutes and then rotate it again and let it heat for another 15 minutes depending on the size of the chicken pot pie.
If it's a larger pot pie then it will take longer to heat than a smaller pot pie so adjust the time until your chicken pot pie or any other pot pie is reheated.
You can reheat chicken pot pie in a microwave but the microwave can easily burn the chicken pot pie if you don't watch it closely enough.
So if you have an oven I would recommend using the oven to reheat the chicken pot pie.
