Roasted Potato Soup with Arugula

A creamy, dreamy soup with roasted potatoes, onions and fresh arugula makes a healthy one bowl dinner.

So easy to make with roasted potatoes

What do you do when you have a ton of potatoes?  Make soup, of course.  The one problem, I did not feel like peeling, cubing and boiling them.  Thank goodness for my trusty baking pan and oven.  The combination of the two save many a weeknight dinner for me.  I threw some onions on the pan with the potatoes and roasted them. Then it was a simple matter of scooping the vegetables into a pot, adding some broth and whirling away with my immersion blender, peel and all from the potato.  It makes one delicious hearty soup, that I added a little peppery arugula in for good measure.  Your kids will not know there are greens in this soup, if they are of the “leafy, green vegetable – hating” variety like my daughter.

Think of this like an Americanized version of the famous French soup, Vichyssoise, Potato Leek Soup.  Leeks are expensive, so I used the humble, delicious and economical onion.  If you would like to spring for a few leeks, go for it.  They would add a lovely flavor to the soup.  You can roast them in place of the onion.  This is an inexpensive, easy and satisfying meal in a bowl.  It will help warm you and give you sustenance to get through these cold winter days.
