This Pressure Cooker Potato Soup has all the flavor of making it on the stovetop but takes a fraction of the time. Using your InstantPot, this soup can be on the table in no time!
This Pressure Cooker Potato Soup is adapted from a recipe in cookbook called The Working Cook which seems fitting for Barbara’s family. It’s hard to manage a full-time job, 3 kids and being a short-order cook to her hungry family. This cookbook has a lot of fast recipes.
She likes this recipe because she can use her electric pressure cooker to cut down on cook time. She made this the morning of the first winter snow; it warmed her entire family up.
Want to know a secret? She was all out of dried thyme, so she substituted poultry seasoning. It has thyme plus a lot more. It was delicious!
