Why You’ll Love This Low Carb Keto Zuppa Toscana
From broccoli cheddar soup to lasagna soup, who doesn’t love to indulge in a big bowl of soup on a cold day?
Oh wait, you’re cutting carbs? Trying to follow a keto friendly diet? I feel ya. Doesn’t it seem like all the comfort foods involve carbs somehow? Well, not this Keto Zuppa Toscana recipe.
Here’s why you’ll love it.
- You may remember this Olive Garden Copycat Zuppa Toscana Soup recipe from a few years back. It’s SO good, and this recipe transforms it into a keto friendly dinner.
- Between the savory Italian sausage and thick-cut bacon, this is a recipe that’s absolutely packed with flavor. You won’t miss the carbs, I promise!
- This is also a soup that’s hearty and satisfying. You know how some soups leave you hungry for more? Not this Keto Zuppa Toscana!
Important Ingredient Notes
- Italian Sausage – I use the mild, bulk sausage. Use spicy if you prefer, or links with the casings removed.
- Thick cut bacon – Some people prefer to add the bacon at the end of the cook time as a garnish so that it stays crispy, not chewy. Your call.
- Beef broth – I like using beef bone broth, which has extra nutrients and collagen.
- Cauliflower – The dream vegetable that replaces potatoes in many low carb meals (like buffalo cauliflower). You can also use turnips if you prefer!
- Heavy whipping cream – For that indulgent creamy broth. The best thing about keto is the heavy cream!
- Spinach – While Olive Garden and many other people use kale, my family prefers the taste of spinach. You choose what you love!
How to Make Low Carb Keto Zuppa Toscana
Cook the Meat: Brown the sausage and bacon in a large soup pot or Dutch oven.
Simmer: Add the beef bone broth, onions, garlic, and cauliflower. Cover and cook on medium heat for about 15 minutes, or until the cauliflower is tender.
Add the Next Ingredients: Stir in the heavy cream and spinach, then cook until the spinach wilts.
Finish: Serve with Parmesan cheese and a pinch of salt, pepper, and/or crushed red pepper flakes.
Tips and Tricks
- Due to the creamy nature of the soup, this one isn’t suited for freezing. You can store leftover Low Carb Keto Zuppa Toscana in the refrigerator for up to 4 days and reheat it on the stovetop over medium or in the microwave.
- Cut the cauliflower into even pieces to ensure it’s all done cooking at the same time.
- There’s a lot of room to make this recipe your own by adding different herbs and spices or other low carb vegetables.
Recipe FAQs
A ketogenic diet is a low carb, high fat diet, similar to Atkins. The goal of a ketogenic diet is to drastically reduce your carbohydrate intake and instead consume fats. By reducing your carbs it puts your body into a state of ketosis, burning fat for energy.
Avoid starches like bread, rice, pasta, and cereal. Beans and legumes are off the menu, and the only fruit allowed is small portions of berries. Potatoes and other root vegetables aren’t allowed, and neither are sugary foods and alcohol. On the bright side, you get to eat Crack Chicken with this easy sauteed cauliflower on the side!
Proteins such as fish, beef, chicken, eggs are all good to eat, as are leafy greens and vegetables that grow above ground like broccoli and cauliflower. Avocado, nuts, and seeds are also good choices and make great snack options. High fat dairy like hard cheeses, high fat cream, and butter get the thumbs up, and stevia is an acceptable keto-friendly sweetener. Thank goodness, because I use that in my favorite Pumpkin Cream Cold Brew coffee!

Tonight I made this soup with chicken broth. Wow I can’t belive how good this is! Thanks for posting.
I am addicted to this soup. I should include my husband and say we instead of I. Make it in my instantpot for 5 minutes then add the cream etc.
I know this is one of the most asked questions with keto recipes, but how did you get such a low carb count on this?
If I use the carb manager app or calculate it myself, the count comes out to be anywhere from 10-13 Net carbs per serving.
Sounds delicious though!
I use MyFitnessPal to calculate the carbs. I think it definitely varies by brand and exact amounts. I weighed my cauliflower and calculated that way, whereas if you’re using more or less it could really throw things off.
AND…you’re right, LOL. I just double checked my numbers, and it’s 12 per serving…I missed the one in typing. Thanks for catching it!
This soup is full of flavor and so easy! Love it 🙂
I love your creativity and I know it is only one meal, but please be careful when cutting out carbs. If you cut out too many, it can severely backfire in the immediate effects and have even worse consequences if done long-term. I love all of your recipes, and good for you for finding an exercise class you enjoy, but if I may say, I don’t think having a “diet competition” is all that healthy. There is enough of that restrictive/unhealthy diet culture in society. You are more than wonderful just as you are.
The nutrition challenge is a personal challenge, not necessarily a competition pitting us all together. And I totally get it, I agree completely that carbs are important 🙂 That said, cutting them down to natural occurring only carbs, in my evening meal has really helped me maintain my weight and feel less bloated (since I workout in the morning). 🙂
Good for you, Aimee, by listening to your body and doing what is best for you and finding a balance that provides you energy to get through what sounds like an intense exercise program. I should try not to spout off nutritional/exercise advice myself; please do not take my comments as a critique of what is working for you. My best to you and your family.
Today is such a gloomy day. This soup is exactly what I need!
Soup is always a great choice on a gloomy day 🙂

I LOVE the cauliflower in this soup!!!
Zuppa Toscana is my favorite! Love this recipe!
I do NOT recommend browning the sausage and bacon together… the bacon was hard to cook, and the sausage got overdone…
This soup is one of my favorites!! Making it this week for sure!
I definitely want to make this this week. This looks so yummy!
I love this version of a classic such a great idea, when you’re watching your carb intake!
