Before I get into this Creamy Mustard Potato Soup, let me explain. Most times, my blog recipes are only tasted and then shared with others. The exception is when people come over for dinner.  I rarely eat full portions and give most of it away to friends or to the needy.  However, when I find the perfect cold-weather soup, I just sit down and eat it.  Don’t tell anyone, but I’m not sharing this creamy Mustard Potato soup with anyone.  #soupselfish

Using Up Leftovers:

This perfect Mustard Potato Soup is the brainchild of a combination of things. First, I spotted a mustard fish soup in a German cooking magazine. Second, is my urgent wish to use up leftover bits and bobs in my fridge and pantry from the holidays. What started as a quest to use up leftover potatoes and cream became my version of that original fish soup recipe. It’s now officially one of my favorite soups. Soup is a journey, people.

There was some sweet onion in the fridge so I threw that in as well. The soup is creamy.  The potatoes add the heft and the mustards add a tangy spicy flavor. The soup comes together fast. From peeling the potatoes to pouring the soup into bowls, the entire process takes only a shade over half an hour.

This Creamy Mustard Potato Soup is garnished with a sprinkle of mustard powder and some parsley but neither is essential to the dish. Leave the soup naked when serving or cut up some chives for garnish.

A small bowl of this soup with a few whole-grain crackers is the best meal I’ve made in a long time.  Simple, flavorful, and satisfying. I regularly share the food I cook for this blog with my friends and neighbors. However, this delicious, warming  soup is not leaving my fridge or my house.

It’s so good, I’m hoarding it.
