Yes, you can freeze pumpkin pie. To freeze pumpkin pie, it's best to first allow it to cool completely after baking. Once cooled, wrap the pie tightly with plastic wrap, followed by a layer of aluminum foil to prevent freezer burn. Place the wrapped pie in the freezer, where it can be stored for up to 1-2 months.
When you're ready to enjoy the frozen pumpkin pie, remove it from the freezer and let it thaw in the refrigerator overnight. It's not recommended to thaw pumpkin pie at room temperature, as this can lead to potential food safety issues. Once thawed, you can serve the pumpkin pie cold or warm it in the oven at a low temperature before serving.
