Clean pumpkin by wiping down outside with a wet towel or rinsing under water.

Place whole pumpkin on top of the trivet. You can remove the stem or leave it on.

Close pressure cooker lid and make sure the pressure release valve is in the "sealing" designation.

Set pressure to High Pressure and a cook time of 15 minutes. It will take a few minutes for the device to pressurize. If your pumpkin is smaller than 2 lbs. use 12 minutes of cook time.

Once the time is up, carefully quick release to release pressure.

Remove lid and carefully scoop pumpkin on to a plate or cutting board. Pumpkin will be very soft.

Slice in half and remove seeds. Peel away pumpkin skin. It should peel away from the flesh very easily.

Place pumpkin flesh into a bowl and mash with a fork until smooth. You can also use an immersion blender or food processor for this step if you prefer.

Once cool, use in your favorite recipes or store for later.
