Sharing is caring!

Want to make fresh and preservative-free Pumpkin Puree at home? But if you think it takes a lot of time or too much work? They try this Instant Pot Pumpkin Puree or make pumpkin puree in an electric or stovetop pressure cooker.

Making the puree at home is satisfying, easy, and economical. It is budget-friendly and once you start making your own, you would be happy to ditch the canned pumpkin puree. I bet you will always use the fresh and purest puree for all your pumpkin cakes, pumpkin pies, waffles, etc.

Recently I made this Pumpkin Nasturtium Cheese Bread which is bursting with flavours from peppery nasturtium and is cheesy. It gets the lovely orange colour from fresh pumpkin puree.

As intimidating or difficult it may sound, it is not. It is a breeze to make the pumpkin puree or boil any squash in an Instant pot or a pressure cooker. With no babysitting and it comes out good and in less time.

Pumpkin puree in an Electric or stovetop pressure cooker or oven?

The good thing about using an Instant pot or a pressure cooker over an oven method is that you need not babysit it. 

In an oven, one needs to check in between, but in a pressure cooker, you just set the cooker or the timer in the Instant pot and let it do its magic. Another thing is that in an oven you would need to preheat, which again takes time. 

But yes if you have to make puree for many pumpkins, it is best to make it in the oven. That is if you are making a puree of 3-4 pumpkins then I would suggest using the oven as you might be able to add all in one go, whereas in an Instant pot or pressure cooker you would be limited with the quantity. But definitely, one medium size pumpkin (like 8-10 inches) can go and one medium size pumpkin gives you a good amount of puree.

Cutting the pumpkin to make the puree

I hear you, the difficult part of any squash is the cutting or chopping process. I used to dread this process earlier too. But to make the puree all you do is just cut it in half. One can even use the whole pumpkin and just pierce in between instead of going through the process of cutting and chopping. I prefer cutting it and removing the flesh and seeds before cooking.

I am saying pierce the pumpkin, as when you put the whole pumpkin inside without piercing it might not cook properly or might burst inside.

How to make pumpkin puree in Instant Pot

The first step I do is clean and rinse the outer skin well. Then I cut the pumpkin into 2 large halves. Scoop out the seeds. Do not discard the seeds, they can be roasted for a tasty snack.

Once done, I add some water to the inner of my Instant pot or pressure cooker. Place a trivet or a large plate inside. Place my pumpkin halves on it and let it pressure cook. Once the pressure has been released and the pumpkin cooled completely, I remove the skin. The skin comes off easily. At times I even use the skin that is soft. Yes, they are edible and full of nutrition, there is no point in throwing them.

Blend the pumpkin in the puree and pass it through a sieve if required. Tada, you are done, fresh and preservative-free Pumpkin puree is ready. 

How to make pumpkin puree in a Pressure cooker

For the stove-top pressure cooker follow the same procedure as in Instant Pot. Pressure cook for 3 whistles or as per your cooker settings

How to make pumpkin puree in an Oven or Bake a pumpkin for puree

For the oven method, I slice the pumpkin into slices. Roast the pumpkin in a preheated oven at 180 Deg C for 30-40 until the pumpkin is done. We know this when the pumpkin appears soft and the skin starts to pull off.

How long does fresh pumpkin puree last in the fridge?

This pumpkin puree stays good in the refrigerator for 4-5 days when stored in an air-tight container.

Can we freeze Pumpkin puree?

This pumpkin puree can be frozen. Either store them in a zip lock or an air-tight container. I like to store them in batches or in a zip lock so that it is easier to defrost. When you flatten in a zip lock and store, you can remove as much as required to defrost from the sides.

The pumpkin puree would stay good for 6-8 months in the freezer or more. When required simply defrost and use as required.

One can follow the same process to make a puree of butternut squash or even boil sweet potato or potato in an Instant Pot or stove top pressure cooker.

  • Once the mixture is cooled, store it in an air-tight container in the refrigerator for 4-5 days or in the freezer for 6-8 months.


Do not overfill the pressure cooker or the Instant pot.
I would recommend using a large pressure cooker, at least 5 liters to pressure cook, If you are cooking a whole pumpkin at once without cutting or just cutting it into 2.
Else you can cut the pumpkin into smaller size pieces and add around ¾ the capacity of your cooker.
