As a food blogger/recipe developer, I often come up with an idea for (what I assume to be) a creative & clever recipe, only to find out that the “unique” idea has been done. Many times over.

Case in point: sweet potato vichyssoise.
Google this term, and the Internet will yield pages of results. And here I thought I had created something new!

I was inspired to make a sweet potato version of the classic potato leek soup after tasting a delicious batch of Ina Garten’s Zucchini Vichyssoise made by my mother-in-law. I’ve always loved my mom’s vichyssoise, and was excited about Ina’s addition of zucchini. You can eat vichyssoise hot or cold, and seeing as though Spring weather is unpredictable, I thought this would be the perfect between-seasons soup.

Although I love the traditional white potato vichyssoise, the idea of subbing in sweet potatoes occurred to me; this should come as no surprise given my complete adoration of the orange spud.

This sweet potato version turned out to be a delicious departure from the traditional soup.
Plus, you just can’t beat that gorgeous color ;).

If you’ve never worked with leeks before, here’s a quick note: Be sure to wash them well, as they tend to harbor grit and dirt between their layers.

I think the easiest way to do this is to place the chopped leeks into a big bowl of cold water. The sediment will sink to the bottom, leaving you with perfectly cleaned pieces of leek.

I felt compelled to snap a few shots of the fresh veggies, as well as a handful of progress pics.
I’ll let the photos do the talking!








Have I mentioned on the blog how much I love my immersion blender? One my favorite wedding registry presents.
I also adore my Le Creuset dutch oven. Perfect for making soup.

I served the vichyssoise hot, with a side of Sweet Potato Cornbread. It was a delightful dinner for a cold Spring evening!
