Use it within 3 to 4 days, or freeze it. Opened canned pumpkin is a low-acid canned food, and the USDA says to keep those in the fridge for 3 to 4 days (USDA FSIS). The quickest ways to use it: stir it into oatmeal or yogurt, make pancakes, or turn it into a creamy pasta sauce or soup tonight.
How long does opened canned pumpkin last?
In the fridge: 3 to 4 days. It is safe to keep it in the can, but the USDA notes food tastes better moved to a glass or plastic container with a lid.
In the freezer: food kept frozen at 0°F stays safe indefinitely, and the time limits are for quality only (FoodSafety.gov). Libby's suggests using frozen pumpkin within three months (King Arthur Baking).
Toss it if it smells off, looks strange, or shows any mold.
Is it puree or pie filling?
Check the label before you cook. "100% pure pumpkin" is just pumpkin, so it works in sweet or savory food. "Pumpkin pie mix" already has sugar and spices added (Libby's), so keep it for sweet things like oatmeal, smoothies, or muffins.
How much is actually left?
A 15-ounce can holds about 1 7/8 cups. Most recipes call for 1 cup, so you usually have a bit less than a cup left over. That is the right amount for any one idea below.
What can you make with leftover pumpkin for breakfast?
- Oatmeal: stir in a few spoonfuls with cinnamon and a little maple syrup.
- Yogurt bowl: swirl it into plain or vanilla yogurt and top with nuts or granola.
- Smoothie: blend with a banana, milk, and a pinch of cinnamon.
- Pancakes or waffles: whisk about half a cup into your usual batter with a pinch of spice.
- Muffins or quick bread: a half batch uses up the rest of a can.
What can you make with leftover pumpkin for dinner?
Plain pumpkin is mild and creamy, so it acts like a sauce base.
- Pasta sauce: see the worked example below.
- Soup: simmer with sautéed onion, stock, and curry powder or a splash of coconut milk, then blend.
- Chili: stir a few spoonfuls into a pot of chili to thicken it.
- Mac and cheese: whisk some into the cheese sauce.
- Curry: add it to a coconut curry with chickpeas or chicken.
Worked example: 20-minute pumpkin pasta for two
You need: about 3/4 cup pumpkin puree, half an onion, 1 to 2 garlic cloves, 2 servings of pasta, Parmesan, salt, pepper. Sage or chili flakes if you have them.
- Boil the pasta. Save a mug of the cooking water before you drain it.
- Soften the chopped onion in butter or oil for 5 minutes, then add the garlic for 1 minute.
- Stir in the pumpkin and a big splash of pasta water until it looks like a sauce.
- Add the pasta, a handful of Parmesan, salt, and pepper. Loosen with more water as needed.
- Taste. Add sage, chili flakes, or a squeeze of lemon if it needs a lift.
No onion? Skip it and add a little more garlic. No Parmesan? Any salty hard cheese works.
Can you freeze leftover canned pumpkin?
Yes. Spoon half-cup portions into a lightly greased muffin tin, freeze until solid, then pop them into a freezer bag. Each portion is ready for one batch of pancakes, soup, or pasta later. Thaw in the fridge overnight.

FAQ
Can I store opened pumpkin in the can?
Yes, the USDA says it is safe. It will taste better in a glass or plastic container.
Can I use pumpkin pie mix in savory recipes?
Not really. It is sweetened and spiced, so it will taste like dessert. Use it in oatmeal, smoothies, or muffins instead.
How do I thaw frozen pumpkin?
Overnight in the fridge works best. Thawed pumpkin can look a little separated; Libby's says that does not affect taste or texture, so just stir it (Better Living).
What else can I do with half a can of pumpkin?
Fold it into overnight oats, blend it into a dip with garlic and yogurt, or add a spoonful to a grilled cheese. For more use-it-up ideas, see how to reduce food waste at home.
