Low Carb Zuppa Toscano Soup

This Low Carb Zuppa Toscano Soup is everything you love about the traditional Olive Garden soup, but low on carbs and full on flavor!

This Low Carb Zuppa Toscano Soup is low on carbs, but HUGE on flavor! My whole family loved this easy soup!
Low Carb Zuppa Toscano Soup is filled with zesty Italian Sausage, crispy bacon, kale and tender cauliflower florets all in a creamy broth.

You guys, lately I’ve become obsessed with kale. I know I’m super behind on the trends, because kale was super popular a couple years ago, but lately it’s been finding it’s way into all of my dishes!

My family LOVED this low carb version of the Olive Garden copycat Zuppa Toscano Soup!

Mostly in part to the fact that I’ve been trying to eat on this low carb, keto friendly diet in preparation for my trip to Hawaii. Kale is just a great green vegetable that is similar to spinach and perfect for when you’re getting tired of spinach…

Just sayin…

I'm so obsessed with this low carb, keto friendly Zuppa Toscano soup made with cauliflower!

As the weeks have gone on with this low carb diet, I have been missing things like potatoes. I think of all the carbs, potatoes are my weakness. Cauliflower is a great substitution for potatoes in a low carb diet. While they don’t hold the same starchiness, they still give you that feeling of comfort that you’re used to with potatoes.

This soup is so quick and easy to make too, which is always a bonus. The cauliflower actually cooks much faster than potatoes, so this low carb version is much quicker to make than the original copycat version from Olive Garden.

This Cauliflower Zuppa Toscano Soup is crazy delicious and perfect for your low carb diet!

Low Carb Zuppa Toscano Soup

The best thing about this recipe is that it’s all made in just one pot. I mean, it’s as soup… so that makes sense, but I still love it. There is nothing more comforting than a delicious soup recipe on a cool Fall evening, am I right?

My family LOVED this low carb version of the Olive Garden copycat Zuppa Toscano Soup!

My kids LOVED this delicious soup recipe. They went back for seconds, and so did I!

  • 1 lb. ground Italian sausage
  • 4 slices thick cut bacon, diced

  • 1 1/2 cups chopped kale
  • 1 cup heavy cream

  • In a large dutch oven or stock pot brown the sausage until crumbled and cooked through. Use a slotted spoon to remove the sausage to a paper towel lined plate and set aside.

    Food is not just about what we taste in our mouths and how it fills our bellies. It also fills our souls. Whether they are family, friends, or strangers who we meet during our travels, food connects us to people, and to memories.

    Thank you for sharing your dish food!

    Amazingly Delicious. Since I am O blood type I needed to substitute Broccoli for the Cauliflower and turkey bacon and turkey Italian flavored sausage for the 2 meat items. It was quick and simple to make! I wondered as I made it how such ordinary ingredients were going to taste anything but boring. I was very surprised at the result.

      You can use potatoes, which is the traditional way this soup is made. If you’re trying to keep it low carb still you could try using broccoli in it’s place?

    I substituted the sausage with a rotisserie chicken from Sams Club. I diced it up in small pieces. I also just Real Bacon Bits. It turned out fantastic. This simple modifications made for a super easy recipe be even easier.

      Coconut milk would change the flavor of the soup, but if you’re looking for a dairy free substitution you could try that or maybe even almond milk? Hope that helps!

    These will range a little depending on the exact brands of sausage and bacon you use. Does not include the cheese as that is added as desired. But this gives you a general idea of the content.

    Very yummy, thanks for the recipe! I had cooked bacon and then cooked pork sausage in the bacon fat ahead of time, so I just sauteed the onions in butter for the soup and added the meat once the onions were done. Either way, I was pleasantly surprised at the amount of flavor without a ton of seasoning added! I also used 6 cups of chicken broth and 1 cup of water. Great Keto recipe find!! Even my picky husband liked it!

    The Atkins diet can make you lose weight but is extremely unhealthy as well. My father actually tried this diet, lost 20 pounds, and gained 25 pounds back when he began to eat regularly. This was the same for several other people I know. People who are lean eat well-balanced diets because they are listening to their bodies and fill their stomachs with a large variety of foods, fulfilling all of their bodies needs.

    Made this soup last night, and the whole family loved it!! I’ve had the original at Olive Garden, and this was a perfect switch, all the flavor minus the carbs. New favorite, and so good for a low carb meal!!!

    It boils my bottom when someone makes a claim such as, “low carb” or, “Keto friendly” and then gives you no nutritional information!

      Easy enough to figure out if you are on Keto or low carb. She posts the recipes. Do the math. Or don’t and move on. No need to be snippy.

    How can I find all the nutritional info for this recipe. It sounds great but I can’t use it without the macro nutritional info. Please provide. Thanks

    1. Dee Hanten

      I am on that road to dieting and low carb seems to be working for me…..how about listing carbs with your recipes…much appreciated, thanks, Dee

    Tried this tonight and it was AWESOME. Even the picky eater in the house loved it. Will definitely make this again. Glad there is extra for lunch this week.

  12. Judi

    I love this soup! I’ve always made it and ate it, but we’re going on a RV trip and I’d like to make it and take it. Do you think it will freeze, or will it get nasty and separate?

    I LOVE this soup and always make it with hot Italian sausage. It is SO flavorful and tastes even better the more you warm it up.
