Comfort food season is here and what’s more comforting than a big steaming bowl of soup filled with chicken, vegetables, and rich broth?

Nothing. That’s right, my friends, nothing is more comforting than keto soup. And the variations are virtually endless. You can make Keto Enchilada Soup, Thai style Chicken Soup, or my famous Chile Relleno Chicken Soup.

But this creamy keto Tuscan Chicken Soup is my new favorite and it’s easy to see why. Chunks of tender chicken with plenty of garlic, sun-dried tomatoes, and spinach in a creamy sauce. Oh and some hidden cauliflower for a thick and luscious broth.

Can you dig it?

Tuscan Soup Inspiration

Typical Tuscan style soups are often made with white beans like cannellini. Or they are imitations of Zuppa Toscana from The Olive Garden.

But I drew my inspiration for this keto chicken soup from the myriad recipes for Creamy Tuscan Chicken. You have probably seen these recipes all over the internet, and they look absolutely delicious. Pan seared chicken in a creamy Tuscan style sauce, they make your mouth water instantly.

It looks so rich and comforting, I got thinking about how to play with those flavors. It was cold and rainy here, and I was chilled to the bone. I simply needed a hot cup of soup.

And so Creamy Tuscan Chicken Soup was born!

How to make keto Tuscan chicken soup

This recipe is so rich and flavorful, and certainly worth the 40 minutes it takes to make. Here are my best tips for getting it right:

  1. Cut the chicken into bite-sized pieces. This helps it cook through faster so you can get your soup on the table that much sooner. I like to make them about 1/2 an inch, as it makes the soup easier to eat.
  2. Sauté the chicken. You can use butter or oil for sautéing, and you want to cook it all the way through. Toss in the sun-dried tomatoes along with the chicken as it will intensify their flavor. Remove everything to a plate while you prep the rest of the soup.
  3. Sauté the garlic. Add the remaining butter or oil and cook the garlic with the tomato paste and Italian seasoning until fragrant.
  4. Stir in the broth and the cauliflower. I know cauliflower is an unusual ingredient in a Tuscan style soup, but it helps make a thicker broth without adding more fat or thickeners. Cook until the cauliflower is tender.
  5. Blend it up! Once the cauliflower is tender, blend the broth until smooth and thick.
  6. Put it all back together. Add the broth back to the pan and stir in the chicken. Then add the spinach and cook a minute or two until just wilted.
  7. Stir in the cream and Parmesan.
  8. Grab a spoon and dig in! I guarantee you this is some of the most heavenly keto soup you will ever make.

Frequently Asked Questions

I prefer chicken breasts, can I use those instead of thighs?

Absolutely! Still cut them into 1/2 inch pieces and cook accordingly.

Can you use pre-cooked or rotisserie chicken?

That should work too and will make this delicious soup even faster. Sauté the sun-dried tomatoes along with the garlic, tomato paste, and Italian seasoning, and the proceed as directed.

Chop the cooked chicken or shred it with your fingers before adding in to the soup in Step 5.

I’m dairy free, can I still make Keto Tuscan Chicken Soup?

Yes! Simply use coconut cream in place of the whipping cream, and add about 1/4 cup of nutritional yeast in place of the Parmesan.

Do the leftovers re-heat well?

They reheat very well. As with all creamy soups, it’s best to reheat them gently over medium low heat. Don’t let it come to a boil.

I hate cauliflower, what can I sub for it?

Use chopped zucchini instead, as it also helps thicken keto soups. Cook it until tender, just as you would the cauliflower, and blend it up.

Storage Information

Creamy soups are always best served fresh or within a few days. You can store Creamy Tuscan Chicken Soup in the fridge for up to 5 days, as long as your cream was fresh. Reheat gently in a pot over medium low heat.

I don’t recommend freezing soups that have cream in them, but you can certainly prepare the soup up to the point of Step 6 and freeze at that point. Add the cream after the soup is fully heated through.

    Loved this recipe but I doubled the tomato puree amount for a denser flavour and with the garlic as the recipe doesn’t state prep so I minced it before use.

    Excellent! Prepared exactly as written. Highly recommend this recipe.

  3. Cathy Bryan says:

    I tried this Tuscan Chicken Soup and it was delicious. I left it with chunky veggies and chicken because I wanted a little more texture. It was so rich in flavor and very satisfying. Every one of Carolyn’s soups that I’ve tried have been so delicious. They make you feel like you’re eating things you shouldn’t, but luckily are following your Keto plan. Thank you so much Carolyn!

  4. Do you blend the entire soup with the immersion blender? Or, just the cauliflower?

  5. Ronda Bishop says:

    You don’t need to be keto or low carb to enjoy the decadence of this delicious Creamy Chicken Tuscan Soup. Carolyn never disappoints!

  6. 5 stars
    Delicious! But you’ve got to make it with chicken, as the recipe indicates. I didn’t have chicken on hand and made it with sausage. Oh, no! Awful! But making as written it comes out delicious.

  7. Josephine Gonzales says:

    This soup was absolutely delicious – what a flavour. I made it the other day just as written, but did add a bit more broth after the cauliflower simmer. Hubby and I got two meals out of it, so I guess we ate more than our fair share. Thanks so much Carolyn.
