It's very easy to cook whole pumpkin in your Instant Pot, and the skin slips right off!
Put the trivet (the one that comes with your Instant Pot i)nside the inner pot and pour over 1 cup of water.
Place the whole unpeeled sugar pumpkin on the trivet.
Lock the lid, turn the steam release vent to 'sealing' and using the manual setting, adjust it to cook for 15 minutes at High Pressure for a 2.5lb pumpkin about 12-13 minutes for smaller pumpkins, add a little more time more for bigger pumpkins.
You may need to remove the stem to make it fit in your pot, but you can leave the stem on if it fits.
When the cook time is up open the vent right away. (quick release)
To test if the pumpkin is cooked, you should be able to very easily slide a small sharp knife through the skin and into the pumpkin. If it's not cooked, simply cook it for another 5-6 minutes at high pressure.
When the pumpkin is fully cooked some of the skin should be slipping off. Once it's cooled enough to handle you can remove the rest of the skin, seeds, and fiber
Choosing Pumpkins - I used a sugar pumpkin which is the standard small pumpkin you'll find in US grocery stores in the Fall. Not all pumpkins are great for eating so be sure to check the variety first. The only other thing to be mindful of is to make sure that it will fit in your pressure cooker! I used a small 2.6lb pumpkin and there was plenty room in my 6qt Instant Pot.
Pumpkin Seeds - Once the pumpkin has cooked and you chop it up you can save the seeds if you want to dry them out and bake them in the oven later on, they make a great healthy snack!
