If you'd like to make a creamy 3 ingredient potato soup, you have a couple of options. First, try blending some or all of the soup with a stick blender. This will give it a thick, creamy texture. Second, you could turn this into a 4 ingredient potato soup recipe and stir in a little bit of heavy cream at the end
Store any leftovers in an airtight container in the fridge for up to 4 days. Reheat on the stove or in the microwave.
