The answer to how long to cook a pumpkin in the Instant Pot depends on its size and whether you’re cooking it whole or in pieces.
Generally, a whole small pumpkin (about 2–3 pounds) cooks in 12–15 minutes at high pressure, while larger ones take closer to 20–25 minutes.
If you’re cooking cut chunks or halves, the time drops to about 8–10 minutes, making the Instant Pot one of the fastest ways to get tender, scoopable pumpkin.
In this post, we’ll break down exactly how long to cook a pumpkin in the Instant Pot, how to prep it, and a few tips so yours comes out perfectly soft every single time.
Let’s dive in.
How Long to Cook a Pumpkin in the Instant Pot
The short answer is that cooking a pumpkin in the Instant Pot takes anywhere from 8 to 25 minutes of pressure time, depending on how you cut it.
Here’s the breakdown so you know exactly how long to cook a pumpkin in the Instant Pot for your situation.
1. Whole Small Pumpkin (2–3 Pounds)
A whole small pumpkin cooks in about 12–15 minutes on high pressure.
You’ll want to pierce it a few times with a fork so steam can escape and the skin doesn’t burst.
Add one cup of water to the Instant Pot, place the trivet inside, and set the pumpkin on top.
After the cooking time, do a quick release so it doesn’t overcook and turn mushy.
2. Whole Large Pumpkin (4–6 Pounds)
If your pumpkin is bigger, plan for 20–25 minutes at high pressure.
The larger size means more time for heat to penetrate all the way to the center.
Keep in mind that a very large pumpkin may not even fit in a standard 6-quart Instant Pot, so cut it down if needed.
3. Halved or Quartered Pumpkin
When you cut the pumpkin into halves or quarters, cooking time drops to about 8–10 minutes.
This is my favorite method because it’s faster and the pieces cook evenly.
Scoop out the seeds first, then lay the pieces skin-side down on the trivet.
The result is soft, scoopable flesh that’s ready for pies, soups, or purees.
4. Pumpkin Chunks or Cubes
Cubed pumpkin is the quickest option, taking just 5–7 minutes at high pressure.
This works great when you’re making a curry, stew, or mashed pumpkin dish.
Cut the chunks into similar sizes so they all finish cooking at the same time.
How to Prep a Pumpkin for the Instant Pot
Knowing how long to cook a pumpkin in the Instant Pot is only half the battle.
The prep matters just as much, and it’s simple once you know the steps.
1. Wash and Dry the Pumpkin
Give the pumpkin a good rinse under running water to remove dirt and any residue.
Pat it dry with a towel so it’s not slippery when you handle it.
2. Decide Whether to Cut It
You can cook a pumpkin whole in the Instant Pot, but cutting it speeds things up.
If you’re short on time, halve or quarter it before cooking.
3. Remove the Seeds and Strings
If you cut the pumpkin, scoop out the seeds and the stringy pulp with a spoon.
Save the seeds if you want to roast them later for a crunchy snack.
4. Add Water and Use a Trivet
Pour one cup of water into the Instant Pot and place the trivet at the bottom.
The trivet keeps the pumpkin out of the water so it steams rather than boils.
5. Lock, Seal, and Set the Time
Close the lid, set the valve to sealing, and choose the pressure cook setting.
Use the times above based on your pumpkin’s size and cut.
Once the timer beeps, do a quick release for cut pieces or a natural release for a whole pumpkin.
Tips for Perfect Instant Pot Pumpkin Every Time
A few small tweaks make a big difference when you cook a pumpkin in the Instant Pot.
1. Don’t Skip the Trivet
The trivet is what keeps your pumpkin steaming instead of sitting in water.
Soggy pumpkin is the number one mistake people make, and the trivet prevents it.
2. Test for Doneness
After cooking, poke the pumpkin with a fork or knife.
If it slides in easily with no resistance, it’s done.
If not, add 2–3 more minutes and cook again.
3. Let It Cool Before Scooping
A freshly cooked pumpkin is extremely hot, so let it rest for a few minutes.
Once it’s cool enough to handle, the skin peels right off or the flesh scoops out with a spoon.
4. Use the Right Pumpkin Type
Small sugar pumpkins are the best choice for cooking because they’re sweet and less stringy.
The giant carving pumpkins are watery and tough, so save those for jack-o’-lanterns.
So, How Long to Cook a Pumpkin in the Instant Pot?
How long to cook a pumpkin in the Instant Pot comes down to size and cut, ranging from 5 minutes for cubes to 25 minutes for a large whole pumpkin.
The Instant Pot turns a normally time-consuming task into something you can knock out in under half an hour.
Whether you’re making pumpkin puree, soup, or pie filling, this method gives you soft, sweet results with almost no effort.
Grab your pumpkin, fire up the Instant Pot, and enjoy fresh homemade pumpkin all season long.
