How Long Does Canned Pumpkin Last After Opening?

Pumpkin puree is a pantry staple year-round, but it’s especially popular in the fall. It’s a key ingredient in countless seasonal recipes, including pies, pancakes, breads, cookies, and more. Its savory base pairs perfectly with brown sugar and maple syrup to enhance the sweetness. Since canned pumpkin puree is a reliable go-to, the last thing you want is for it to spoil before you can use it all. To help you make the most of every can, we share how long pumpkin puree lasts, how to store it, and how to tell when it’s gone bad.

What Is Canned Pumpkin Puree?

Pumpkin puree is simply mashed pumpkin that is canned. It’s often confused with pumpkin pie filling, which contains added spices and sweeteners typically used for making pie. Pumpkin puree is more versatile because it has no added ingredients, which makes it ideal for cooking and baking from scratch.

How Long Does Canned Pumpkin Last?

The U.S. Department of Agriculture (USDA) classifies canned pumpkin as a low-acid canned food, meaning it can grow harmful bacteria if not stored properly, both on the shelf and after opening. Unopened pumpkin puree can last two to five years, so any leftover cans from last year are likely still safe to use.

Once opened, pumpkin puree should be used within three to four days. Be sure to transfer it to an airtight plastic or glass container and store it in the refrigerator. To avoid waste, plan your recipes ahead of time. Many call for a full can, but double-check how much you’ll need to prevent leftover puree from sitting unused and spoiling.

Signs Canned Pumpkin Has Gone Bad

While unopened canned pumpkin puree can last two to five years in storage, it’s important to inspect the can before opening. Physical damage or improper storage, such as extreme temperatures, can cause canned food to spoil. According to the USDA, signs of spoilage include a swollen or bulging can, leaks, rust, deep dents along the seams, or a hissing sound or pressure release when opened.

Once opened and stored in an airtight container in the refrigerator, pumpkin puree should still be checked for spoilage—even if it’s been fewer than three to four days. Watch for signs such as an off smell, mold, slimy texture, or excessive liquid separation before consuming, according to the USDA.
