I made a low carb version of the famous Zuppa Toscana Italian Sausage Soup. It comes together with very little prep time, it eats like a meal–and it freezes well. In fact, it tastes even better the next day.
There's nothing like a delicious bowl of homemade soup. Especially one like this Italian Sausage Soup. It's so easy and full of fresh ingredients. Who needs Olive Garden when you have this tasty soup recipe you can make at home?
What Is Zuppa Toscana Anyway?
Italian Sausage Soup is a classic soup originating from Italy. The term Zuppa Toscana is just a broad term meaning "Tuscan Soup." This is because the soup originated in Tuscany.
Zuppa Toscana is traditionally made with:
- Cannellini beans.
- Kale
- Zucchini
- Potatoes
- Celery
- Carrots
- Onion
- Tomato
- Olive oil
- Chili powder
- Italian bacon
However, Olive Garden has a version that has made this kale and sausage soup somewhat famous, and it's made a bit differently using sausage, chicken broth, potatoes, kale, and various spices.
Italian Sausage Soup doesn't use any unusual seasonings and has pretty basic ingredients. If you prefer to use Swiss chard or kale for your greens, that's perfectly ok.
I used frozen spinach without even thawing it. If you want to use fresh greens, that's great, just be sure to use a bigger pot or put the greens in a little bit at a time as they will take up more room when they're fresh.
This makes a generous 3-quart batch or 12 cups. Each serving of sausage soup is 2 cups.
How to Make a Stovetop Keto Italian Sausage Soup
- Sauté the Italian sausage. This pan is too small! Use a nice, 3 quart-sized pan for this. This is the 3-quart Lodge pan I ultimately finished cooking it in.
- Stir onions and garlic in to the sausage.
- Add riced cauliflower (frozen or fresh).
- Add spinach or kale (frozen or fresh) and add the seasonings.
- Cover and cook. Once it is done cooking, slowly add in cream, and grated cheese.
- Less than 30 minutes later, you're done.
There's no need to wait until colder weather pops up to make this Italian Sausage Soup. You don't have to be a fancy Italian cook either. This recipe is extremely easy and quick to make. Not to mention, it's delicious and will hit the spot every time.
CAN I FREEZE THIS ITALIAN SAUSAGE SOUP?
You bet you can! This soup freezes very well and even tastes better the next day since all the flavors have had a chance to really meld together. Not to mention, this soup is great for meal prep.
Here's how I freeze it:
- Let the soup cool.
- Portion into small freezer-safe containers or souper cubes.
- Date containers.
- Freeze.
Not only is it extremely healthy, but it sticks the keto lifestyle parameters. Since it's easy to freeze and is quick and easy to make, it makes for a delicious meal that can be made for the entire next week.

Tips and Tricks for Making This Italian Sausage Soup
- This makes a generous 3-quart batch or 12 cups. Each serving is 2 cups. Be sure to use a 3-quart soup pot unlike me, who started with a 2-quart pot and had to switch partway through. AS YOU CAN SEE IN THIS VIDEO! Doh!
- You can use frozen veggies for this soup. It will just take a little bit longer to cook them. Just thwack the frozen package of greens on the kitchen counter, and add the chunks into the soup. No need to get fancy with thawing 🙂
- You can substitute spinach, kale, or swiss chard for the greens.
- This is a great meal prep soup since it seems to get better and better as it keeps.
So next time you're craving some Zuppa Toscana soup, whip up a batch of the delicious low carb Italian Sausage Soup and get your fix!
Ingredients
- 2 tablespoons olive oil
- 1 pound bulk hot or mild Italian sausage, removed from casing
- 1 cup onions, chopped
- 1 tablespoon Minced Garlic
- 12 ounces Frozen Riced Cauliflower, thawed
- 12 ounces Frozen Spinach, thawed
- 2 cups Water
- 2 teaspoons Ground Black Pepper
- 1.5-2 teaspoons Kosher Salt
For Finishing
- 1/2 cup Heavy Whipping Cream
- 1/2 cup shredded parmesan cheese
- additional cheese for garnishing each cup of soup
Instructions
- Set out the cauliflower and spinach to thaw while you get the other ingredients ready. Chop the onion, and mince the garlic.
- Heat a 3 quart pot on medium high. When it is hot, add in the sausage and using a wooden spoon, break up the meat so it is more like ground beef rather than a sausage. In other words, smooth the sausages down and break them into bits. Be ruthless.
- Add in the onions and garlic and mix well.
- Add in the cauliflower and kale.
- Add in 2 cups of water and place a lid on the pot. Allow the soup to come to a boil, about 7-8 minutes. Cook for another 2-3 minutes.
- Slowly pour in the cream. Add in the shredded parmesan cheese. Allow the soup to come to a boil again.
- Serve 2 cups per serving, with additional cheese as desired.

Urvashi, could you substitute fresh or frozen cauliflower florets for the riced cauliflower? Would they turn to mush? Or are you using the riced cauliflower to thicken the soup? We love chunky-ish soups.
For a non-Keto soup, it could be thickened by adding dried potato flakes or finely shredded russet potato at the beginning . Or, for that matter, a blond roux.

Would love to try this but don't understand how you get 12 cups of soup from just the 2.5 cups of liquid the recipe calls for?

Not only do you have the bulk from the sausage and veggies but all of them also release water during cooking—and none of it evaporates in pressure cooking

Super easy and flavorful! Def a keeper for a weekend quick meal. Thank you!

This is a great keto recipe- easy to follow. I added kale instead of spinach. I also added waaaaay more liquid than 2 cups of water . Probably used 6 or 8 cups, including 2 cups of chicken broth for more flavor. Not sure if I misread something or if it is a misprint. ?
A wonderful warming soup that I will make again!
