Keto Italian Sausage and Cauliflower Rice Soup is satisfying and delicious!

Keto Italian Sausage and Cauliflower Rice Soup

I’ve mentioned before that we enjoy eating soups all year round – even during the warm weather months. I especially like that soups are a ‘cook once, eat several times’ type of food – and that’s definitely the case when you cook up a big pot of our Keto Italian Sausage Cauliflower Rice Soup.

While a little bit of dicing, ricing and chopping is required to make this delicious, low-carb soup, once all of the prep is done, our Keto Italian Sausage Cauliflower Rice Soup cooks up in just twenty-five minutes. Leftovers quickly reheat on the stovetop or in the microwave.

This Keto Italian Sausage Cauliflower Rice Soup is a great option if you are looking for a low-carb or keto meal. We swapped in riced cauliflower for traditional rice, but even if you aren’t eating lower carb these days, you’ll love this flavorful soup!

How do you make Keto Italian Sausage Cauliflower Rice Soup?

You’ll start by ricing a head of cauliflower—either by running the cauliflower florets against the coarse blades of a box grater, or use the grater attachment of a food processor. (You can also buy bags of riced cauliflower in the frozen section of your supermarket, but it is less expensive and not that difficult to rice the cauliflower yourself at home.)

Next, saute diced onions, celery, garlic, red pepper flakes, and sweet Italian sausage in a large pot. Add tomato paste, then canned diced tomatoes with juice to deglaze the pan.

Then, pour beef stock into the pot with the sausage. (Definitely use homemade beef stock if you have it, or a good, flavorful brand.)  Also add the cauliflower rice and seasonings—then heat through until the cauliflower is tender.

Finally, add in baby spinach and some grated Parmesan cheese—and you’re ready to serve your Keto Italian Sausage Cauliflower Rice Soup.

Can this Keto Italian Sausage Cauliflower Rice Soup be frozen?

Yes! This Keto Italian Sausage Cauliflower Rice Soup freezes quite nicely – so you can keep some on hand in a freezer container or plastic bag for those hot summer days when you don’t feel like cooking. As noted above, thaw, then simply reheat in a saucepan on the stove top, or in the microwave.

Keto Italian Sausage and Cauliflower Rice Soup

  • Author: A Family Feast
  • Prep Time: 20 minutes
  • Cook Time: 25 minutes
  • Total Time: 45 minutes
  • Yield: 8 servings
  • Category: soup
  • Method: stovetop
  • Cuisine: Italian


3 tablespoons extra virgin olive oil, divided

1 cup onions, diced

1 cup celery, diced

1 tablespoon garlic, minced

Pinch red pepper flakes

1 pound sweet Italian sausage, removed from casings

2 tablespoons tomato paste

1 14.5-ounce can diced tomatoes

2 quarts beef broth or stock

½ teaspoon dried basil

½ teaspoon dried oregano

½ teaspoon freshly ground black pepper

2 cups cauliflower rice (*see Notes below)

½ pound baby spinach

½ cup grated Parmesan cheese

Kosher salt, as needed


In a medium soup pot over medium heat, add 2 tablespoons of the olive oil and once hot, add the onions and celery. Saute five minutes.

Add the remaining oil, garlic, pepper flakes and the sausage meat and cook to brown the meat, about five more minutes.

Clear a spot in the center and add the tomato paste and cook for three minutes, then stir it into the mixture.

Add the diced tomatoes and loosen up any brown bits on the bottom then add the stock, basil, oregano, pepper and the raw cauliflower rice, and cook just until the cauliflower is tender, about 2-3 minutes.

Add the spinach and Parmesan cheese and remove from heat. The spinach will cook from the heat of the soup within a minute or two.

Taste and season with salt only if needed.


*To make the cauliflower rice, grate a small head of cauliflower on the large holes of a box grater, or use a grating wheel on your food processor. If you have a little more or less than two cups, that is fine.

    I add a half pound of mushrooms and I often use frozen cauliflower rice and even frozen spinach. It’s still good! My husband also likes his soup spicier, so I use more spice.

      Thanks for the suggestions!

    It’s great that it’s keto, but don’t let the name fool you into thinking that the soup will taste “less than.” No substitutions were necessary and the flavors were perfect. Rare to make soup and not have to add salt & pepper when eating. My daughter, who hates soups/broths, actually ate this and said it was really good. High praise coming from her!

      Thanks so much Simone! So glad the recipe was a hit – especially for those who *think* they don’t like soup! 🙂

    Oh my gosh! I happened to have all these ingredients and tried your recipe. It was the BEST soup I’ve ever had. I substituted cauliflower gnocchi (frozen in bag) because I didn’t have riced cauliflower. It was a nice texture. I also added bacon because why not. This recipe would be fabulous as written though.

    HI Martha! Well, I am off to the Asian mega store you have heard about before. I love soups too and it’s been in the high 90’s here but no matter. How do you feel about adding escarole or chopped cabbage rather than the spinach? Not a fan of Popeye’s favorite veggie. I see you have added plenty of garlic! Just call me “garlic girl”. Hope you summer is going splendidly so far. Thanks for another keeper. It’s a done deal for me today regarding this recipe.

    • Martha wrote:

      Hi Doris! I’d personally go with kale or escarole over cabbage (mostly because cabbage will really change the flavor of the soup) – you’ll just have to allow for more cook time to cook the escarole (or kale). Hope you love the soup! (And glad you approve of the garlic amounts!) 😉
