Myth or Fact: Can Pumpkin Pie Sit on the Counter Overnight?

What the USDA says

The US Department of Agriculture's Food Safety and Inspection Service says homemade egg-rich pies, such as pecan, pumpkin, lemon meringue and custard, must be kept refrigerated after cooking and cooling. Cream and chiffon pies must also be stored in the fridge. These pies keep for three to four days. Fruit pies such as cherry and apple are different: they can stay at room temperature for one to two days (USDA FSIS).

Iowa State University Extension explains why. Bacteria grow rapidly between 40°F and 140°F (about 4°C to 60°C), so homemade pumpkin and pecan pies shouldn't stay at room temperature for more than two hours (Iowa State University Extension). The one exception is pies sold unrefrigerated in shops, which are made with shelf-stable ingredients and preservatives. Follow the date and instructions on the label.

Did grandma just get lucky? Possibly. Not every pie left out overnight will make someone ill. But the risk is real, and holiday tables often include the people most vulnerable to food poisoning: young children, older relatives and anyone who is pregnant.

Five classic pumpkin desserts, and how to store them

1. Pumpkin pie. Pumpkin purée, eggs, evaporated milk, cinnamon, ginger and nutmeg in a pastry case. Cool, chill, then cover loosely. Eat within three to four days.
2. Pumpkin cheesecake. Cream cheese, eggs and pumpkin on a ginger-biscuit base. It's a dairy-and-egg dessert, so it lives in the fridge until shortly before serving.
3. Pumpkin roll. A thin, spiced sponge rolled around a cream cheese filling. The filling makes it a fridge dessert.
4. Baked pumpkin custard. The crustless version, baked in small ramekins. Same rules as the pie.
5. Pumpkin bars with cream cheese frosting. The cake is sturdy, but the frosting is dairy. Keep them covered in the fridge.

Tips for the big day

• Bake the pie the day before. Let it cool completely, chill it uncovered, then wrap it loosely so condensation doesn't make the crust soggy.
• If it hasn't fully cooled within two hours, put it in the fridge unwrapped to finish cooling.
• Take it out a few minutes before serving if you prefer a softer filling.
• Return leftovers to the fridge within two hours of serving.

The bottom line

Keep the recipes and change one habit. Pumpkin desserts made with eggs, milk or cream cheese belong in the fridge, not on the counter overnight.
