Creamy Keto Italian Sausage Soup

Warm and creamy with Italian sausage spice, you’re going to love this creamy keto Italian sausage soup on a cold snowy night. It’s one of our favorite ground sausage keto recipes. Just close your eyes and imagine yourself in the Italian Alps as you eat your Keto Zuppa Toscana!

Creamy Keto Italian Sausage Soup

What do you imagine when you hear the words creamy keto Italian sausage soup? First, I like to picture myself by a roaring fire at an antique wooden family dinner table with snow falling lightly through the picturesque window.

The kids are smiling at each other as they enjoy their soup, and the husband is laughing about a story he just told. Then, I smile contentedly and look around as I warm my hands on the sides of my bowl.

Let’s keep that pretty picture in our heads! The winter season is nearly upon us, sooner here in Northern Colorado than I’d necessarily like.

However, the cold and snow make me crave the comfort of warm bowls of keto friendly soups. And, to be perfectly honest, it’s fabulous to have a big pot in the fridge prepared over the weekend you can just pull out, warm up, and call everyone to dinner. It’s especially convenient when you have all those fun after-school activities like volleyball, basketball, karate, piano, and so on preventing you from kitchen time on weeknights.

Creamy Keto Italian Sausage Soup. Easy, low carb, and delicious, this gluten free recipe will have your family asking for more! #ketosouprecipes #lowcarbrecipes

Cold day keto soups

Yesterday morning we had to get up early to head down to Denver for an appointment. It’s the middle of October right now, and when we left the house at 6:30 am it was 11 degrees Fahrenheit with a blanket of white snow covering the neighborhood.

Yes, you read that right 11 degrees. True, this is Colorado, but that’s not a normal temp for mid-October when the average low is about 37!

So, we exclaimed about the weather, discussed it with everyone we saw, and posted about it on social media, my daughter and I decided it was definitely soup weather.

If you ask my girl what kind of meat she likes she will immediately say sausage, meatballs, or pork chops. In short, she’s a meat lover and so this creamy keto Italian sausage soup is always popular on the menu. She has to have sugar free and gluten free recipes so it’s a good thing meat is popular!

💭 Top tips

Perfect creamy keto Italian sausage soup

I really like to add cream cheese to soups to give them an easy low carb creamy goodness. I’ve tried many different methods to add said cream cheese to soups, smoothies, and desserts.

Far and away, the best way I’ve come up with to evenly distribute the cream cheese in soup or even a muffin batter is to blend the cream cheese up with wet ingredients before adding it to the main mixture.

In this creamy keto Italian sausage soup recipe, I use a cup of broth and cream cheese and blend them together before adding them to the soup. Why do I do this? It’s the easiest and most practical way to not have cream cheese lumps floating about your soup!

Now, if you don’t have a blender you can take room temperature or slightly warm cream cheese and whisk or stir it into your simmering soup. It is possible. I’ve done it before. It’s how I do it in the video.

However, it does take longer to get all the lumps out and mix it in completely without making a mess.

Also, I tend to forget to get the cream cheese out of the refrigerator early so blending it up is a fabulous way to make up for my lack of planning skills.

🔪 Instructions

How to make creamy keto Italian sausage soup

AKA Keto Zuppa Toscana.

(Just pretend you’re in a chalet in the Italian Alps. Yes, please. Celebrate keto Italian food!)

First of all, to make this creamy keto Italian sausage soup, melt the butter in a soup pot or dutch oven over medium-high heat.

Second, you’re going to scrape in the chopped onion and minced garlic from the cutting board and mix those around with the butter.

Then, the Italian sausage goes in to cook for about 4-5 minutes or until the onion is soft and the meat is browned and filling the kitchen with good smells. It should brown evenly so stir it around and break it up as it cooks. Cheers for keto recipes with ground sausage!

As the meat browns, add the zucchini to cook. I like to use zucchini in soups as a sort of a pasta replacement and another texture. Then pour in three cups of the bone broth.

Zucchini and meat in the pot

Sometimes, I even peel the zucchini and take out any large seeds simply because the children are more likely to eat it that way. They are less likely to attempt to pick it out if they don’t see the green. At least that’s my kids!

You can julienne it sort of in more of a noodle shape, or slice and quarter it, or just chop it as you like!

Now for the good stuff!

Okay, next add the herbs, basil, oregano, a bay leaf, and then the cayenne pepper. Stir that up a bit then add the diced tomatoes. After that, bring the pot to a boil then lower to medium heat or low to simmer.

While the soup is simmering, place the remaining cup of bone broth and cream cheese in a blender and blend it up until it’s smooth with no lumps. Then, pour it into the rest of the soup and stir.

Next, chop up about 2 cups of spinach and mix it in the soup to wilt. You can serve it almost right away or allow it to simmer for another half hour or so for the flavors to combine. It does taste better if you simmer it a bit longer or make it the day before and heat it for a quick weeknight meal.

Last but not least, don’t forget the cheese!

Serve the bowls of soup topped with shredded parmesan cheese. I like to shred my own if there’s the time because often the pre-grated, shredded cheeses contain potato starch or other things to make them not stick together. That’s not something I want to eat so tend to buy block cheese and prepare it myself.

Eat and enjoy!

👩‍🍳 Variations

There are several variations I’ve had readers try and suggest. One of the most popular is to switch out the spinach for kale. I’ve done this myself many times and highly recommend it!

Others say they also switch out the zucchini for cauliflower to make keto cauliflower sausage kale soup.

Also, it can be turned into a bratwurst soup with slices of bratwurst if that’s what you have on hand. Is bratwurst keto? Well, it’s protein and high in fat so can definitely be added to a keto diet. Just watch any added ingredients. Creamy bratwurst stew? Why not?

There’s a lot you can do with it, depending on what you have on hand. I love that it’s a super versatile recipe.

There’s a sorrow and pain in everyone’s life, but every now and then there’s a ray of light that melts the loneliness in your heart and brings comfort like hot soup and a soft bed.

❤️ Keto Tuscan Soup = Keto Zuppa Toscana = I love soup

What are your favorite keto soups and stews? Do you create your own with whatever’s in the fridge or stick to recipes? I do a little of both as it’s a great way to get rid of leftovers! Keto sausage dishes are super popular for a cold winter evening around here, and we often have keto sausages around.

I love this delicious recipe, and it’s truly one of my favorites. I’m not opposed to eating it for breakfast, breakfast sausage soup anyone?

What tastes do you like that might work well in soup or stew form? Philly cheesesteak? Cheeseburger? Chicken enchilada? We love keto ground Italian sausage recipes like this keto sausage casserole, slow cooker – who knew you could cook a casserole in the slow cooker!?

On the stove or in the slow cooker or Instant Pot, soups speak comfort in fall and winter!

Yes, I like to think of some of my favorite meals and winterize them so to speak in easy peasy stew form. Winter is the ideal time to make delicious recipes like this, Keto Jambalaya or Keto French Onion Soup anyone?

Now, I hope you try this creamy keto Italian sausage soup, find a fireplace and a book set in Italy and enjoy some keto zuppa Toscana!

Hi! Just made this soup for the very first time. Sooooo good! Very flavorful. I used fire roasted tomatoes as that was what I had on hand. I will be making this again you can be sure. Thanks for the recipe.

Fabulous recipe, thank you so much !!! I substituted chicken stock for beef and zucchini for celery. So delicious and more filling than I’d expected. Ate nearly two servings though because it was so yummy and it still came under my carb limit!


Thursday 14th of December 2023

This soup is amazing!!! My 12 year old and 23 year old both LOVE it. This has become a regular for me. I'm not a skilled cook and this comes out perfect every time!


Friday 20th of October 2023

The most fabulous soup! The only thing I do differently is add diced/brown kielbasa (turkey) for more of a meaty texture. Definitely one of my go-to soups!
