Set your Instant Pot to saute “normal”. When it reads “Hot”, add the butter. Once the butter melts, add the onions and carrots. Cook for 5-6 minutes until soft.
Add the pumpkin pie spice, salt, ground black pepper, ginger paste, and garlic paste to the pot. Cook for an additional minute. Hit the cancel button.
Stir in the brown sugar, chicken broth and pumpkin puree. Give it all a mix. Make sure to scrape the bottom of the pot. There should not be anything stuck. This will avoid getting a “burn notice”.
Secure the lid onto the pot. Press the soup button and set for 10 minutes. Make sure that your vent is in the sealed position. When the timer goes off, natural release for 10 minutes.
After the 10-minute natural release, press or slide the vent release valve to let out all the pressure. It’s now safe to open the lid.
Blend using an immersion blender or blend in 2 batches in a regular blender. Serve and enjoy!
Note: I like to top mine with pumpkin seeds and a good drizzle of honey. You could also stir in a bit of half and half to make it a bit richer.
