Thanksgiving dessert usually sits on the counter while everyone talks, then goes back on the counter for “later.” With pumpkin pie, that habit is the one food safety officials ask you to change.
The short answer: 2 hours
Pumpkin pie is a custard pie. The filling is made with eggs and milk (often evaporated milk), and foods like that can grow bacteria when they sit at room temperature.
The U.S. Food and Drug Administration (FDA) says to refrigerate any food that needs the fridge within two hours, and it names pumpkin pie by name. The USDA says the same in its holiday guidance: refrigerate the pie and any leftovers within 2 hours.
That 2-hour clock starts when the pie comes out of the oven, or when you bring it home from the store.
Why 2 hours?
The USDA calls 40°F to 140°F the “Danger Zone.” In that range, bacteria can double in number in as little as 20 minutes. A kitchen full of people, a warm oven and a busy afternoon put a pie right in that range.
If the room is very warm (above 90°F), the USDA shortens the limit to 1 hour.
How long pumpkin pie keeps
| Where | How long |
|—|—|
| On the counter | Up to 2 hours |
| In the refrigerator (40°F or colder) | 3 to 4 days |
| In the freezer | 1 to 2 months for best quality |
The 3 to 4 day window comes from USDA and FDA guidance for leftovers. After that, throw it out, even if it looks and smells fine. The bacteria that make people sick usually do not change how food looks or smells.
How to store it
- Let it cool, then cover it. A fresh pie can cool on the counter, as long as it goes into the fridge inside the 2 hours.
- Cover it loosely with plastic wrap or foil, or use a pie keeper.
- Keep the fridge at 40°F or colder. An appliance thermometer is the only way to know.
How to freeze it
Pumpkin pie freezes well. Cool it completely, wrap it tightly in plastic wrap and then foil, and freeze it. Thaw it overnight in the refrigerator, not on the counter. The crust may be a little softer after freezing.
What about store-bought pies?
Some store pies are sold unrefrigerated. Follow the label on the package. Once you get it home, cut it or serve it, treat it like a homemade pie and put it in the fridge within 2 hours.
The easy habit
Serve the pie, enjoy dessert, and set a kitchen timer for 2 hours. When it rings, the pie goes into the fridge. You can still have a slice later. It is just a cold one, and it is safe.
