Why a 15 oz Can of Pumpkin Puree Isn’t 2 Cups
The “15 oz” on the label is net weight, not fluid ounces. Two cups would be 16 fluid ounces of volume, but pumpkin puree is slightly denser than water, so 15 ounces by weight fills less than two cups. At about 245g per cup, the 425g inside a standard can comes out to roughly 1.73 cups, which most recipes round to 1¾ cups. If you want the exact weight per cup and smaller fractions, our guide to 1 cup pumpkin puree in grams breaks it down further.
When a Recipe Asks for Cups Instead of Cans
| Recipe Calls For | What to Open |
|---|---|
| 1 cup | About ⅔ of a 15 oz can |
| 1½ cups | Most of a 15 oz can (about ¼ cup left) |
| 2 cups | One 15 oz can plus ¼ cup from a second can |
| 3 cups | One 29 oz can (a little left over) |
| 3½ cups | Two 15 oz cans |
Many classic baking recipes are written around a single 15 oz can, so if a recipe says “1 can” you can use it as is. A standard 9-inch pie, for example, uses one full can, which is why it’s the reference for our breakdown of how many slices in a pumpkin pie. For other baking ingredients measured in the same recipe, weighing is just as useful as it is for flour, where cup measurements vary a lot by technique.
Pumpkin Puree vs Pumpkin Pie Filling
Both come in similar 15 oz and 29 oz cans and sit next to each other on the shelf, but they are not interchangeable. Pumpkin puree is just cooked, mashed pumpkin. Pumpkin pie filling already contains sugar and spices, so using it in place of puree changes both the flavor and the nutrition of a recipe. Check the label for “100% pumpkin” if a recipe calls for puree.
Using and Storing Leftover Puree
Once opened, move leftover puree out of the can into a covered container and refrigerate it for up to about a week, or freeze it in measured portions for a few months. A few tablespoons stir easily into breakfast dishes like overnight oats. Plain puree is also low in calories and high in fiber, as covered in our look at whether pumpkin puree is good for you.

Moved into a covered container, it keeps in the fridge for up to about a week, or in the freezer for a few months.
Final Answer: How Many Cups in a 15 oz Can of Pumpkin Puree
A 15 oz can of pumpkin puree holds about 1¾ cups (425g), and a 29 oz can holds about 3⅓ cups. The label shows weight, not volume, which is why a 15 oz can falls short of 2 cups. When a recipe needs an exact amount, a kitchen scale set to 245g per cup is the most reliable way to measure.
