I'm a human being on planet earth. I've lived hundreds of lifetimes. In this incarnation I'm here to advance medicine.

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!

Sweet Potato Zucchini Vichyssoise

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.

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!

inspired by Ina Garten’s Zucchini Vicchyssoise

yield: a LOT of soup! Serves 6-8 as a side; 4-6 as an entree


  • 1 Tbsp butter (or an additional Tbsp olive oil for a vegan version)
  • 1 Tbsp extra virgin olive oil
  • 5 cups chopped leeks, white and light green parts (I used 3 large leeks)
  • 4 cups chopped peeled sweet potatoes (about 2 large potatoes)

  • kosher salt and freshly ground black pepper, to taste


1. Sauté the Aromatics

  • Add the chopped onions and garlic and sauté until the onions turn translucent and fragrant, about 5 minutes.

2. Add Sweet Potatoes and Zucchini

3. Simmer with Vegetable Broth

  • Pour in the vegetable broth, ensuring it covers the vegetables. Bring the mixture to a gentle boil.

4. Reduce Heat and Simmer

  • Reduce the heat to low, cover the pot, and let it simmer for about 20-25 minutes or until the sweet potatoes are tender.

5. Blend Until Smooth

  • Using an immersion blender or a countertop blender, carefully puree the soup until it’s velvety smooth.

6. Add Coconut Milk

7. Serve and Garnish

  • Ladle the Sweet Potato Zucchini Vichyssoise into bowls.
  • If desired, garnish with fresh chives for a burst of color and flavor.
