Pumpkin Pie at Room Temperature
First off, understand that homemade pumpkin pies are less forgiving than, say, homemade apple pies, because the former is made with multiple eggs and heavy cream. You need to treat your homemade pumpkin pie like you would a quiche. According to the FDA, homemade pumpkin pie can be left at room temperature for two hours, after which it is in danger of growing harmful bacteria.
Homemade vs. Store-Bought
“Pumpkin pie is technically a custard pie,” says Valeri Lucks, founding partner and chief executive pie officer at Honeypie Cafe in Milwaukee, Wisconsin. “Homemade ones all need be stored in the fridge because they do not have the preservatives and such that commercial bakeries use to make something room temp safe.” Homemade pumpkin pie is safe in the fridge for two to four days, and you should refrigerate the pumpkin pie promptly after it cools. Place your pie in a sealed container or wrap it in plastic wrap or foil to refrigerate. You can also bake your pumpkin pie weeks ahead of time and freeze it.
Refrigerating Store-Bought Pumpkin Pie
Store-bought pumpkin pies, which include shelf-stable ingredients such as preservatives, are a different story. If your pie was sold unrefrigerated in the store, it can continue to be stored on your counter until the sell-by date. In general, store-bought pies last about two to four days after their printed date in the refrigerator and about six to nine months in the freezer. If your pumpkin pie does not have a sell-by date, and you bought it from a bakery or a place that baked the pumpkin pie in a traditional way (without preservatives), follow the homemade pumpkin pie rules above. If you left any pumpkin pie out for too long, don’t be tempted to roll the dice. Thanksgiving is about more than just pumpkin pie. It’s about gratitude and family and friends—none of whom want to get sick!
