Ingredients and Variations
MEATS: Italian sausage and bacon are yummy additions to any soup, but feel free to use leftover meat like cooked chicken, beef, or turkey. Even frozen meatballs can be used!
VEGETABLES: Kale makes for the best veggie for Zuppa Toscana because it stays firm during cooking. But, spinach, collard greens, even cabbage can be substituted. Cauliflower replaces the potatoes, but broccoli, zucchini, or mushroom can be added for extra color, texture, and nutrition!
SOUP BASE: Chicken broth and heavy whipping cream give this soup its signature creamy base. Add additional spices like Italian seasoning for a fuller-bodied soup.
GARNISHES: Offer a few bowls of different garnishes so everyone can help themselves! Shredded mozzarella cheese, sliced black olives, diced tomatoes, green onions, jalapenos—these are just a few of the options.
DIPPERS & SIDES: Or serve with some air fryer kale chips or Daikon fries. Add a crispy green salad with tangy and creamy Caesar Salad Dressing, and dinner is served!

REPIN this Keto Zuppa Toscana Soup Recipe!
Yummy, as usual!! Another great, flavorful, easy keto soup. Thanks, Holly.
I am so glad you enjoyed this soup Cioci!
What can I use as a non-dairy substitute for heavy cream? Thanks! 🙂
I haven’t tried it so I can’t say for sure Brenna. You could try coconut cream or another non-dairy milk. If you try it I would love to hear how it turns out!
Brenna just so you know, this soup is also delicious without the heavy whipping cream. You do not need to put the cream in this soup but it will be a brothy soup verses a creamy soup.
Very true Shirley!
I’m writing next week’s shopping list, including what I need to make this soup. From the photo, I can’t tell for sure, so I’ll ask. Is the Italian sausage uncased? Did you take it out of the case or did you buy it uncased? Can I use sliced cased Italian sausage?
I used uncased Italian sausage. You can either buy it uncased or take it out depending on what you can find in the store! I hope this helps Candy.
I’ve been making this soup for years! It wasn’t until I went on my carb diet that I realized that all I needed to do was substitute the potatoes for the cauliflower. My family wants their soup every time they come home now. One granddaughter is obsessed and will call me from college and say I’m coming home will you make my soup!
I use hot Italian sausage in mine as it really gives it the best flavor and a bit of a zing as well! Occasionally I have to eat the one with potatoes because I’m just craving my soup..lol.
If made with potatoes, this does not freeze well, the cauliflower does freeze well but not meant for long term freezing. I would say no longer than 2 weeks.
HI Shirley. I am glad that you found this low carb Toscana soup a recipe that you and your family can enjoy together. Have a great rest of your day!
