A 15 oz can of pumpkin puree holds about 1 3/4 cups. Pumpkin puree is thick and smooth, so it measures well in a measuring jug or by spooning it into a cup measure and levelling it off. The can weighs 425 g in total, and because puree is dense — mostly water and pumpkin flesh with no added liquid to drain — nearly all of that weight is usable puree. The 1 3/4 cup figure is the one to use when a recipe calls for pumpkin in cups, and it is also the reason most pumpkin recipes are written around a single can: a classic pumpkin pie takes exactly one can, and a batch of pumpkin muffins takes exactly one can too.
Pumpkin puree is a seasonal ingredient for most cooks, and the can is the practical way to buy it — fresh pumpkin needs roasting, scooping and blending, and the yield is unpredictable. The can is consistent: every 15 oz can is about 1 3/4 cups, every time. That consistency is what makes canned puree the standard for baking, where the moisture content matters and a variable amount of pumpkin would change the texture of a cake or a pie. If you bake with pumpkin more than once a year, the can figure is worth knowing by heart.
Can of pumpkin puree conversion table
The table below breaks a 15 oz can into fractions, so you can measure out half a can for a small batch or work out how many cans a large bake needs. All volumes are for the puree spooned into a cup measure and levelled.
| Amount | Cups (approx.) | Tablespoons | Fluid ounces |
|---|---|---|---|
| 1/4 can | 0.44 cups (about 1/2 cup) | 7.0 tbsp | 3.5 fl oz |
| 1/2 can | 0.88 cups (about 7/8 cup) | 14.0 tbsp | 7.0 fl oz |
| 3/4 can | 1.31 cups (about 1 1/4 cups) | 21.0 tbsp | 10.5 fl oz |
| Full can | 1.75 cups (about 1 3/4 cups) | 28.0 tbsp | 14.0 fl oz |
| 2 cans | 3.50 cups (about 3 1/2 cups) | 56.0 tbsp | 28.0 fl oz |
The can weighs 425 g in total (15 oz). Pumpkin puree is not in the ingredient density table, so no grams-per-cup figure is published here — measure by volume, and weigh the puree directly if your recipe works in grams.
Worked examples
A classic pumpkin pie
A classic pumpkin pie for eight people uses one whole can of pumpkin puree — 1 3/4 cups — whisked with two eggs, 3/4 cup of sugar, 1 teaspoon of cinnamon, 1/2 teaspoon of ginger, 1/4 teaspoon of nutmeg and 1 cup of evaporated milk, then poured into a pastry case and baked. The can is the recipe: the filling is designed around exactly 1 3/4 cups of puree, and using more would make the filling too wet to set, while using less would make it dry and over-spiced. Bake at 190°C for 15 minutes, then reduce to 175°C for 40 minutes, until the centre barely wobbles.
Pumpkin muffins for a bake sale
A batch of twelve pumpkin muffins uses 1 cup of pumpkin puree, which is a little more than half a can. Measure 1 cup into the batter with the oil, eggs and sugar, and save the remaining 3/4 cup in the fridge — it keeps for three to four days and is enough for a second half-batch of muffins, a pumpkin smoothie, or a small pan of pumpkin soup. The muffins bake in 20 to 22 minutes at 180°C. Do not be tempted to use the whole can in one batch: the extra moisture would make the muffins dense and under-baked in the middle.
Pumpkin soup for four
A pumpkin soup for four people uses 1 1/2 cups of pumpkin puree, simmered with onion, garlic, vegetable stock and a pinch of nutmeg, then blended smooth. That is most of a can — measure 1 1/2 cups and keep the remaining 1/4 cup for stirring into porridge or a curry the next day. Because the puree is already cooked, the soup only needs fifteen minutes of simmering, and the blending is what makes it silky. A swirl of cream and a few toasted pumpkin seeds on top finish it.
How the figure is worked out
The figure above is worked out by simple division, not by guessing. The package weight is a standard 15 oz can of pumpkin puree. Divide that weight by the grams in one cup and you get the number of cups in the package. Because cup weights for dry ingredients depend on how the cup is filled, the result is approximate, and the honest way to use it is as a planning figure: it tells you how many batches a bag will cover, not the exact cup count to the last spoonful.
Practical guidance
Do not confuse pumpkin puree with pumpkin pie filling. They sit next to each other on the shelf and the cans look alike, but pie filling is already sweetened and spiced — using it in place of puree will double the sugar and spices in your recipe. The label is the check: puree should list only pumpkin as the ingredient. If the label lists sugar, cinnamon and other spices, it is pie filling. If you have already bought pie filling by mistake, you can still use it in a pie, but reduce the sugar and spices in the recipe accordingly and taste as you go.
Spoon the puree into your measuring cup rather than pouring it — it is too thick to pour, and pouring leaves air pockets that make the measurement unreliable. Level the top with a knife. Store leftovers in a sealed container in the fridge for three to four days, or freeze them in 1-cup portions in bags for up to three months. Frozen puree thaws overnight in the fridge and works exactly like fresh from the can in baking, which makes it worth freezing the 3/4 cup that is always left after a recipe that needs 1 cup.
Frequently asked questions
Is pumpkin puree the same as pumpkin pie filling?
No. Pumpkin puree is plain cooked pumpkin with nothing added. Pumpkin pie filling is puree with sugar and spices already mixed in. They are not interchangeable: using pie filling in place of puree will make your recipe far too sweet and over-spiced. Check the label — puree should list only pumpkin.
How many grams are in a can of pumpkin puree?
The can weighs 425 g in total (15 oz). Pumpkin puree is not in the ingredient density table, so there is no published grams-per-cup figure for it. If your recipe works in grams, weigh the puree directly on a kitchen scale rather than converting from cups.
Can I make pumpkin puree from a fresh pumpkin?
Yes. Halve a small sugar pumpkin, scoop out the seeds, roast cut-side down at 190°C for 45 minutes until soft, then scoop out the flesh and blend until smooth. The yield varies with the size of the pumpkin, which is exactly why canned puree is the standard for baking — it is consistent at 1 3/4 cups per can, every time.
How long does opened canned pumpkin keep?
Three to four days in the fridge in a sealed container, or up to three months in the freezer. Transfer it out of the can as soon as you open it. Freeze in 1-cup portions so you can defrost exactly what a recipe needs.
Can I use pumpkin puree in savoury dishes?
Yes. It is excellent in soups, curries, pasta sauces and risottos, where it adds body and a gentle sweetness. Use it the same way you would in baking — measure 1 3/4 cups per can — and season it well, because plain puree is very mild on its own.
