Sometimes recipes come together out of whatever’s on hand and turn out to be some of my favorites, and this Butternut Squash and Kale Soup is one I came up with when I had butternut squash and kale in the fridge. The bonus ingredient in this soup is the Farro I’d been craving ever since I tried it in Farro with Mushrooms, Thyme, and Balsamic Vinegar.

The butternut, kale, and farro combination here was wonderful, but if you wanted a gluten-free version you could make this with brown rice and if you wanted fewer carbs you could make it with cauliflower rice. And any of those variations on this soup with Autumn flavors would also be very tasty. 

This recipe would be perfect to make on the weekend and enjoy for a meatless lunch or dinner. You can use My Top Ten Recipes for Butternut Squash to see more of my butternut squash faves!

How to Make Butternut Squash and Kale Soup:

(Scroll down for complete recipe with nutritional information.)

  1. If you’re using farro, start by soaking it for at least 15 minutes. 
  2. If you don’t want to Peel and Cut Up a Butternut Squash, I think pre-cut squash cubes are great for soup. 
  3. Cut the squash into pieces not more than 3/4 inch across. 
  4. Saute the diced onion with the thyme and sage in the soup pot.
  5. Add the stock to the onions and herbs and bring to a low simmer; then add the farro and simmer 10 minutes.  (You can skip this extra ten minutes if you’re using brown rice; cauliflower rice will be added towards the end of the cooking time.) 
  6. Add the squash cubes and simmer about 30 minutes. 
  7. Mash the squash a bit so some pieces will thicken the soup, then add the kale (and cauliflower rice if you’re using that) and simmer 20-30 minutes more. 
  8. Stir in a little balsamic vinegar if desired, and serve hot.
  9. This is good with a little Parmesan cheese sprinkled on at the table.

Autumn Harvest Soup with Butternut Squash and Kale

Yield 8 servings
Prep Time 45 minutes
Cook Time 1 hour
Total Time 1 hour 45 minutes

This delicious Autumn Harvest Soup with Butternut Squash and Kale has some of my favorite fall and winter ingredients.

Ingredients

  • 1 cup Farro (see notes)
  • 1 onion, finely chopped
  • 2 tsp. olive oil
  • 1 tsp. dried thyme
  • 1/2 tsp. dried sage (rubbed sage)
  • 6 cups vegetable broth
  • 6 cups diced butternut squash
  • 4 cups chopped kale
  • salt and fresh ground black pepper to taste
  • 1-2 T balsamic vinegar (optional)
  • freshly grated Parmesan for serving (optional, this soup is dairy-free without the Parmesan)

Instructions

  1. Soak Farro in cold water 15-30 minutes. (Rice does not need soaking)
  2. Cut butternut squash into cubes not more than 3/4 inches across.
  3. Chop onion, then heat olive oil in bottom of large soup pot, add onion and saute about 5 minutes.
  4. Add thyme and sage and cook 2-3 minutes more.
  5. Add vegetable stock to the soup pot and bring to a low simmer.
  6. Drain Farro and add to stock, then simmer 10 minutes. (You could skip this initial ten minutes of cooking with brown rice.)
  7. Add butternut squash cubes and simmer about 30 minutes, or until squash is quite soft.
  8. Use a potato masher to mash some of the squash so it dissolves into the soup, leaving other pieces whole.
  9. While soup simmers, wash and chop kale.
  10. Add kale to soup (and cauliflower rice if you are using that) and simmer about 20-30 minutes more.
  11. I like the greens cooked fairly well in my soup, check sooner if you prefer chewier greens.
  12. Season to taste with salt and fresh ground black pepper.
  13. If desired, stir in a tablespoon or two of balsamic vinegar right before you serve the soup.
  14. Serve hot, with freshly-grated Parmesan cheese to add at the table if desired.

Notes

Use one cup of brown rice for gluten-free option or 2 cups frozen cauliflower rice for low-carb option. If you don't care if it is vegetarian, this would be great made with homemade chicken stock.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
The use of butternut squash and farro would make this Butternut Squash and Kale Soup phase two or three for the original South Beach Diet.  You could make a lower carb soup by making this with Cauliflower Rice, but soup with butternut squash will never be suitable for strict low-carb diets. Use brown rice to replace the Farro if you want the soup to be gluten-free.

  1. sounds amazing… and healing.

  2. I love everything about this soup, Kalyn– the colors, the flavor, and the nutritional boost! I’m planning on posting on a red lentil and kale soup in which I used red kale too.

  3. Butternut is so beautiful in soup. What a perfect autumn combination. Lovely.

  4. Great looking soup the the flavour contrast of sweet squash against earthy kale sounds yum.

  5. This looks like a hearty soup! I love butternut squash and I’m off to check out your post on how to peel and cut it up!

  6. mmmm…Kale and butternut squash – two of my favorite things, together in one pot. Yummy!

  7. What a fantastic recipe Kalyn and you’re so lucky to have that garden! I was relieved to find that I cut Butternut Squash in exactly the same way as you recommend.

  8. Some of the best soups are born of the simple expediency of using whatever is left over, or what needs to be used up. I think it forces us to try combinations we might never have thought of otherwise.

  9. Am I nutty but I really do find this soup can sweep me off my feet! So beautiful! Healthy and no body would know ;0) until you tell.

  10. Thanks to everyone for the nice thoughts about this. I was so happy with how it turned out.

    For those who haven’t tried farro, it’s very much worth looking for. I can’t find it anywhere in Salt Lake so far (although I am going to try the Italian market on the other side of town.) I know you can buy it at Amazon.com if all else fails. I’m lobbying my local whole foods to carry it, but they look at me like I’m crazy.

    I did buy a bunch of it in Boston and had it shipped, but it hasn’t arrived and I’m getting worried because a few other things that were supposedly mailed to me haven’t shown up either. Fingers crossed that I will get it!

  11. So glad to see that farro made it safely from Boston and into this wonderful soup. The recipe epitomizes Fall for me — dark greens, winter squash, hearty grains.

  12. Kalyn, what a delicious soup. Farro is really a fabulous grain. I don’t eat it often enough but everytime it comes into my kitchen i keep asking myself why i don’t have it more often. I have loads of kale at the moment so i can easily reproduce your dish.

  13. I am a big fan of farro, kale, & sqaush so this a home run – thanks for sharing!

  14. That soup looks wonderful ! I have never heard of farro either but I will be looking for it.

  15. look so yummy! I love soups, when it gets colder like this time of the year they are real comforters 🙂

  16. Kalyn what a beautiful soup! I love your recipes! You enlighten me so much on using veggies in different ways and branching out and trying the unknown!

  17. Great recipe! It looks so fresh, healthy and totally delicious. I love it!

  18. I’ve never used (or even heard of!) farro. I will definitely have to try it out… I’m tring to get Bobby to eat more whole grains 🙂

  19. This looks great, I am very into farro these days – although I haven’t soaked it ahead of time. Interesting.

    I love your header! Although the kid in me wants to collect chestnuts just to throw them 🙂
