To store pecan pie overnight you need to refrigerate the pecan pie.
When storing and keeping pecan pie overnight allow the pecan pie to cool down and then cover the pecan pie in some plastic wrap and place the pecan pie in the refrigerator.
The pecan pie will last up to 4 days in the refrigerator.
Pecan Pies should not be left out at room temperature longer than 2 hours or it can spoil and grow bacteria.
Pecan Pie is best eaten cold or at least cooled down to room temperature.
However some people prefer to eat the pecan pie warm which is okay as well but some people prefer to eat the pecan pie cool or cold.
That's a good thing about pecan pie as it tastes great when eaten either hot, warm or cold.
I prefer to have my pecan pie warmed up just a bit but not too hot but I've also eaten cold or cool pecan pie and it tasted good as well.
Pecan Pies are best served cooled down to room temp or even out of the fridge while some other pies are best served hot or warm straight out of the oven.
There's no certain way that you have to eat the pecan pie or serve it but the pecan pie should be firm and if you prefer to warm the pecan pie up first before eating it you can do so and if you prefer to eat the pecan pie cold or cool you can do that as well.
