Notes
If you have a ham bone, it will add loads of flavor to the potato and ham soup. Just add it to the pot as it's cooking. This is a full pot of soup! Please keep in mind the Instant Pot will take several minutes to come to pressure 10-15 mins. and another 5-10 mins. to release pressure at the end of the cooking time and plan your meal accordingly. Enjoy!
