Every fall I fill my cart with canned pumpkin when it goes on sale, because my family goes through a crazy amount of pumpkin bread and cookies this time of year. The catch? I always end up finding a can from last year hiding behind the soup cans. So, how long does canned pumpkin last, and is that old can still good?
Quick answer: Unopened canned pumpkin keeps its best quality until the best-by date printed on the can, which is usually about 2 years after it was canned. It’s still safe after that date as long as the can isn’t damaged. Once opened, canned pumpkin lasts 3 to 5 days in the fridge in an airtight container, or about 3 months in the freezer.

How Long Does Canned Pumpkin Last? Storage Chart
| Canned Pumpkin | Pantry | Refrigerator | Freezer |
|---|---|---|---|
| Unopened can | Best quality until the best-by date, safe longer if the can is in good condition | Not needed | Not needed |
| Opened | 2 hours max at room temperature | 3 to 5 days (Libby’s says up to 1 week) | About 3 months for best quality |
How Long Does Unopened Canned Pumpkin Last?
If you’re a stock-up shopper like me, this part is a relief. Canned pumpkin puree is a low-acid food, and the USDA says low-acid canned foods keep their best quality for 2 to 5 years. The date printed on the can is the maker’s best guess for peak quality, not a safety cutoff.
So that can from last year? It’s usually just fine! Past the date, the pumpkin may look a little darker and taste less fresh, but it’s still safe as long as the can is in good shape.
When to Throw Out an Unopened Can
That said, I always give old cans a quick once-over. Toss any can that is:
- Bulging, swollen or leaking
- Deeply dented, especially on the seams or rim
- Rusted
- Spurting liquid or foam when opened
These are clear signs the seal failed and bacteria could be growing inside. Please don’t taste it to check. Just throw it out.
Where to Store Canned Pumpkin
Keep unopened cans in a cool, dry spot. My pantry shelf works perfectly. Skip the hot garage and the cabinet above the stove, since heat makes the pumpkin lose quality faster.
How Long Does Canned Pumpkin Last in the Fridge?
Once you open the can, leftover canned pumpkin lasts 3 to 5 days in the fridge. Libby’s says it can keep up to a week in a sealed container, but in my house I play it safe and aim for the shorter end.
Whatever you do, don’t just stick the open can in the fridge. Instead, I scoop the rest into a glass or airtight plastic container, smooth the top, and press plastic wrap right onto the surface. Then I put the lid on, write the date on top, and pop it in the fridge.
How Long Does Canned Pumpkin Last in the Freezer?
Freezing is my favorite way to save leftover pumpkin puree, and opened canned pumpkin can last about 3 months in the freezer. Here are the three ways I do it, depending on how I plan to use it:
- Ice cube trays: Fill an ice cube tray with pumpkin. Each cube holds about 2 tablespoons of pumpkin, perfect for smoothies or oatmeal.
- Muffin tin: Scoop ¼ or ½ cup portions into a muffin tin, freeze until solid, then pop them out and store them in a freezer bag.
- Freezer bags: Measure 1 cup into a heavy-duty freezer bag or freezer-safe zip-top bag, squeeze out the excess air, and freeze it flat.
To thaw it, set it in the fridge overnight, or put the sealed bag in a bowl of cold water if you’re in a hurry. Give it a good stir before using, since pumpkin freezes with a little extra liquid.
Signs of Spoilage
No matter how long canned pumpkin should last, I always give leftovers a quick look and sniff before using them. Here’s what to watch for:
- Mold: Any fuzzy spots mean throw out the entire container.
- Sour smell: Pumpkin should smell earthy and mild. An off odor or sour smell means it’s gone bad.
- Color changes: Dark, brown or gray spots are a bad sign.
- Too much liquid or slime: A little liquid is normal. A slimy texture is not.
My rule is simple: when in doubt, throw it out. A few tablespoons of pumpkin aren’t worth a stomachache!
Pumpkin Puree vs. Pumpkin Pie Filling
These two cans sit right next to each other at the store, so it’s easy to grab the wrong one. Check the label before you buy. Canned pumpkin puree is 100% pure pumpkin. Pumpkin pie filling, sometimes called pumpkin pie mix, already has sugar and pumpkin pie spice added.
They last about the same amount of time, but they can’t be swapped in most recipes. Nearly all of my recipes call for plain pumpkin puree.
Easy Ways to Use Leftover Canned Pumpkin
A 15-ounce can holds about 1¾ cups of pumpkin, and so many recipes only use 1 cup. Since that leftover bit won’t last long, it helps to have a plan. Here’s how I use up the rest:
- Bake my Cream Cheese Filled Pumpkin Bread or Pumpkin Cornbread. Each uses 1 cup of pumpkin puree.
- Make a batch of my Pumpkin Streusel Cheesecake Bars, which also use 1 cup.
- Stir a few spoonfuls into oatmeal or pancake batter.
- Blend a few tablespoons of pumpkin into a smoothie with banana and pumpkin pie spice.
Want to use up a whole can at once? My Pumpkin Spice Cupcakes and Pumpkin Sheet Cake each use an entire can of pumpkin.
Frequently Asked Questions
Can you use expired canned pumpkin?
Yes, in most cases. If the can isn’t damaged and the pumpkin looks and smells normal when you open it, it’s safe to use. It may just have a little less flavor.
Can you eat canned pumpkin straight from the can?
Yes. Canned pumpkin is fully cooked during the canning process, so it’s safe to eat without cooking.
How long is homemade pumpkin puree good for?
Homemade pumpkin puree lasts 3 to 5 days in the fridge or about 3 months in the freezer. Unlike store-bought cans, it isn’t shelf stable.
Does canned pumpkin go bad?
Yes, eventually. Unopened cans slowly lose quality after the best-by date, and opened canned pumpkin will only last 3 to 5 days in the fridge before it can grow mold. Freeze anything you won’t use in time.
With a little planning, not one spoonful of pumpkin has to go to waste, and that sale stash in your pantry stays a great deal. Keep unopened cans in the pantry, freeze leftovers in small portions, and you’re all set for a whole season of fall baking.
