Even Pumpkin Pie can be Kept At Room Temperature For a Short Period of Time.
Preservatives that don’t need to be refrigerated can be found in many store-bought pies. Store-bought pies can be kept for as long as the expiration date on the counter indicates they can be kept. When it comes to pumpkin pies, you don’t have to worry about them going bad on the counter.
It is impossible to compare a pumpkin pie that was purchased at a store to one that was baked from scratch because of the significant differences between the two. Because store-bought pies do not contain any added preservatives, the FDA states that they can be stored at room temperature for up to two hours and then refrigerated for two to four days.
