Pumpkin Pie can be reheated in the oven.
Just preheat the oven to 350 F degrees and place the Pumpkin Pie in the oven for 10 minutes to 20 minutes until warm enough for you.
Just keep an eye on it so that it does not burn.
You can make a pumpkin pie ahead of time and freeze it.
Then you can reheat the pumpkin pie in the oven for 10 to 20 minutes to thaw it and heat it back up when ready to serve.
Pumpkin Pies can be eaten cold or warm but pumpkin pies are best enjoyed warm.
Pumpkin Pie can be frozen after baking it however you should allow the Pumpkin Pie to cool down to room temperature before placing it in the freezer.
You can also refrigerate the pumpkin pie after baking it after allowing the pumpkin pie to cool down for at least 30 minutes.
The pumpkin pie will last for up to 6 months in the freezer.
Pumpkin Pie should not be left out overnight or longer than 2 hours because pumpkin pie can grow bacteria in it if left out at room temperature longer than 2 hours.
So if you're not eating or serving the pumpkin pie within 2 hours then make sure to refrigerate it to keep it safe from bacteria.
You can put a hot pumpkin pie in the fridge if you want too and it will be just fine.
Although it will make your refrigerator come on and stay on longer so that the refrigerator can cool down the heat from the pumpkin pie.
It's recommended that you allow the pumpkin pie to cool down for at least 30 minutes before putting the pumpkin pie into the refrigerator.
I've also left pumpkin pies out overnight and they've been fine even though it's best to refrigerate the pumpkin pie after cooking it if you don't plan to eat it or serve it within the same day or within a few hours.
Leaving a pumpkin pie out overnight is fine and the pumpkin pie will still remain safe to eat the next day without refrigeration.
I've heard before that you should refrigerate the pumpkin pie when not eating or serving it to prevent bacteria from growing on the pumpkin pie.
Pumpkin pies are usually made with eggs, milk and cream which can go bad when left out longer than a few hours.
However while it's recommended to refrigerate pumpkin pie when not eating it within a few hours the pumpkin pie will remain safe to eat when left out overnight.
My Grandma and my mom and even myself have left pumpkin pies out overnight several times and they were okay to eat and nothing bad happened to us.
