How Long Does Canned Pumpkin Last?
Unopened canned pumpkin keeps 2–5 years in the pantry. After opening, refrigerate the puree in a covered container for 3–4 days, or freeze it for 2–3 months.
Canned Pumpkin — unopened
shelf life- Opened: 3–4 days in the fridge
Fridge at 40°F (4°C) or below · freezer at 0°F (−18°C). Freezer times are for best quality; frozen food stays safe longer.
Canned pumpkin is cooked, pureed pumpkin or winter squash, heat-sterilized in the can with nothing added; pumpkin pie filling adds sugar and spice. The dense, low-acid puree is safe for years while sealed. Most recipes leave half a can behind, and that moist puree molds within a week in the fridge.
How to store canned pumpkin
- Scoop leftover puree into a small airtight container right away, smooth the top, and refrigerate it; do not leave it in the open can.
- Freeze leftovers in half-cup portions in freezer bags pressed flat, labeled with the amount, since most muffin and pancake recipes call for a half cup or a cup.
- Thawed pumpkin weeps liquid. Stir it back in for baking, or drain it off for a thicker pie filling.
- Stock up after the holidays if you like, but keep the cans in a cool, dry cupboard and use the oldest first.
- Planning to feed plain pumpkin to a dog? Freeze it in ice cube trays so you can thaw one serving at a time.
How to tell if canned pumpkin has gone bad
- White, gray or green fuzzy mold on the surface of refrigerated puree. Discard all of it, not just the top layer.
- A sour or fermented smell; good canned pumpkin smells earthy and faintly sweet.
- A swollen or leaking can, or puree that pushes out under pressure when the lid is pierced. Do not taste it.
- Watery separation with bubbles, or a slimy film. Plain liquid separating out without bubbles is normal.
Bacteria that cause food poisoning usually do not change the look, smell or taste of food. Go by the time limits first, and the signs above second.

Frequently asked questions
How long does canned pumpkin last in the fridge after opening?
Opened canned pumpkin lasts 3–4 days in the fridge in an airtight container. Some brands suggest up to a week, but plain puree has no sugar, salt or acid to protect it, so the shorter window is the safer one. Freeze what you will not use in that time.
Can you freeze leftover canned pumpkin?
Yes. Canned pumpkin freezes very well for 2–3 months at best quality and stays safe beyond that at 0°F (−18°C). Portion it before freezing, thaw it overnight in the fridge, and stir well, because it separates a little.
Is expired canned pumpkin safe to use?
Usually, when the can is in good condition. The date on the can is a best-quality date, and intact low-acid canned food stays safe past it. Pumpkin more than a few years old can taste flat or slightly metallic. Reject any can that is bulging, leaking, heavily rusted or dented along a seam.
Is pumpkin pie filling the same as canned pumpkin for storage?
Nearly. Both keep 2–5 years unopened and 3–4 days in the fridge after opening. Pie filling contains sugar and spices, but not enough sugar to preserve it. A baked pumpkin pie is different again: it contains eggs and milk and must be refrigerated.
