Keto Zuppa Toscana Soup

I crave Olive Garden’s Zuppa Tuscana’s Soup, so I wanted to create one that would align with my low-carb lifestyle. This Keto Zuppa Toscana Soup has all the same flavors as the traditional with an easy swap of cauliflower florets for potatoes. It is so flavorful and super filling. The perfect meal on a fall or winter evening or weekend!

How Is This Soup Considered Keto?

The traditional Zuppa Toscana Soup has potatoes, which are not considered keto. I simply switched to potatoes out for cauliflower florets and it honestly has such a similar taste. The cauliflower still has a crunch and almost tastes like a real potato. If you are living keto or low carb, you will absolutely love this swap.

Cooking Methods For This Keto Zuppa Toscana Soup

There are many different ways to cook this soup. It really depends on your time. Below are all the ways you can make:

  • Crockpot: If you are running out the door in the morning and want dinner to be ready when you get home, the crockpot method is the way to go. Cook on low for 6-7 hours or on high for 3-4 hours. I like to brown the sausage, garlic and onions together before adding to the crokpot.
  • Instant PotAre you home after a long day and want to make something quick? If so, go with the instant pot method. It can be ready in under 20 minutes.
  • Stovetop: This is my favorite method to use on the weekend. I can cook the sasuage on the stovetop in a dutch oven then add everything in and let it simmer throughout the afternoon. It makes my house smell amazing.

Storage & Meal Prep:

  • Storage: In the refrigerator, your stock, soup or stew will keep for three to four days. For quick and easy reheating, store single-serving portions in individual containers. For family-sized meals, store the soup in larger, resealable containers, and make sure to heat and chill the soup properly when serving and re-storing.
  • Meal Prep: If you are using this for meal prep, store the same way from above, but add the garnish in a different container. After you heat up your soup, add the garnish from the other container to the top.

    1. Hi Theresa,

      I’ve recently updated my blog site. You add it in step 2. Go to and search the recipe for the new visual update. Thanks Theresa for your message.

  1. 4 stars
    Pretty tasty. I did the instant pot method and the flavor was a little watery. Overall we enjoyed this recipe and the family approved!

    1. Thanks so much. It is soup so it should have a texture like that. And there is no water in the recipe so did you add something extra in to make it watery? I call for chicken broth and coconut milk?

  2. Made this for dinner tonight and enjoyed it more than the OG recipe. Rich and luscious! Definitely make this it is a crowd pleaser.

  3. Trying tonight and am excited! On the cauliflower florets, do we put in to simmer for 20 minutes or after 20 minutes to simmer for 5-7 minutes? Couldn’t quite tell from the instructions – thanks so much!
