Fill the Instant Pot to the Max fill water line with hot water.
Set the Instant Pot to the soup setting for 120 minutes.
When it's done, allow it to vent naturally.
Once it's cooled enough to handle, strain out all the really soft bones and vegetables through a strainer and store the liquid contents into Mason Jars.
If you've added the butter to the recipe it will create a nice fat layer on top of each Mason jar that helps preserve the broth. Once the fat cap is broken, the broth needs to be used within 3 to 4 days.
