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:
- 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.
- 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.
- Sauté the garlic. Add the remaining butter or oil and cook the garlic with the tomato paste and Italian seasoning until fragrant.
- 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.
- Blend it up! Once the cauliflower is tender, blend the broth until smooth and thick.
- 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.
- Stir in the cream and Parmesan.
- 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
Absolutely! Still cut them into 1/2 inch pieces and cook accordingly.
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.
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.
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.
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.

Delicious!
We made this and it was SO heavenly it was a delicious explosion of flavor in our mouths. We used homemade bone broth. This will become a staple in our house.
Delicious. Definitely will be making it again.
Might be my new favorite soup! Adapted to my Instant Pot and it was SO good. I can see using the tomato-cauliflower base with other proteins, too, or on its own as a tomato soup. Only used a splash of cream, the cauliflower made it plenty creamy, as-is. Thanks for another great recipe. 🙂
So good! I am new to Keto and looking for super flavorful dishes that are easy and this one was so so tasty. so glad i found your site!
Glad you found me too!
Comfort food that doesn’t feel like Keto! This delicious soup is my new winter favorite. Super easy to make, I used leftover slow cooker chicken and frozen riced cauliflower with an immersion blender and it came out excellent. Saving this recipe!
Thank you!
What a wonderful cold evening soup. I made it for the first time tonight. So flavorful. The only thing I would change next time is I would use chicken breast over thighs (kinda rubbery) and a little less spinach.
It will definitely be in our fall/winter rotation!
I made this for tonight’s Sunday dinner. It’s so delicious!!! Carolyn is my favorite keto go-to cook!!
I’ve made this soup. Oh my, absolutely delicious!!!
Made this in an instant pot late last night as my workday went too long. Didn’t even get to thaw the chicken. Just threw everything together, set for 14mins, & bam! Ready! Just reheated for dinner tonight & it was totally amazing!
Question: do you use jarred marinaded sundried tomatoes, or dry packaged sundried tomatoes?
I used the dried ones but I don’t think it would make much difference.
I did Rachael. That was all I could get. No problem at all.
well, I just finished making the Tuscan chicken soup. has to be a labor of love because I worked on it for a couple of hours. Sitting down now to have first bowl and is very good, but sure took me a long time between chopping, sauteeing etc. my bowl looks exactly like the photo attached with recipe. Thanks for recipe. Super healthy.
I’ve made it twice. Easy, one pot soup. Tastes wonderful and high in protein, relatively low carb.
Hearty and satisfying. My husband is not a soup fan, but that’s OK. I can eat this all by myself for lunch for days!
This is my new favorite recipe! Thank you!!!
