The season of soup is here! It’s time to indulge in all the comfort food.

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?

This past month we’ve had a nutrition challenge at our local CrossFit box. And while I wish I could report that I rocked it, I’m here to say, I failed. I didn’t prepare for this challenge as much as I should have, you know, planning some low carb meals!

Here’s the thing. Carbs and CrossFit go hand in hand. I truly believe I need carbs for all my muscle gains and endurance. However, I tend to choose the wrong carbs. Pastries, donuts, bread, haha!

One thing I do love though is chili and soup. And you may remember this Olive Garden Copycat Zuppa Toscana Soup recipe from a few years back. It’s SO good.

I had to figure out a way to make it CrossFit diet friendly. I mean, keto friendly. Ha, I mean waist management friendly. You know what I mean!

Here’s how I made an indulgent comfort food, like Zuppa Toscana Soup into a keto friendly dinner.

You may first be asking yourself:

Keto friendly Zuppa Toscana Soup recipe #lowcarb

What is a Keto diet

First, keto stands for ketogenic. A ketogenic diet is a low carb, high fat diet. You may be familiar with Atkins, it has many similarities.

The goal of a ketogenic diet is to drastically reduce your carbohydrate (carb) intake and instead consume fats. By reducing your carbs it puts your body into a state of ketosis. Basically, your body becomes quite efficient at burning fat for energy. Which is why many Crossfitters and athletes go on this diet.

It also has other great health benefits, that you can read about somewhere besides this little food blog, haha!

What foods should I avoid on a keto diet

First, the obvious. Wheat-based grains or starches. Like rice, pasta, cereal.

Beans: no chickpeas, peas, beans, lentils, legumes

Fruit: pretty much all fruit except berries (but those are only in small portions)

Potatoes and other root vegetables. No sweet potatoes, carrots, parsnips, etc.

Stay away from sugary foods, most condiments and sauces as they tend to have sugar and unhealthy fats.

Alcohol. WAHHHHHH.

What foods should I eat on a keto diet

Proteins such as fish, beef, chicken, eggs are all good to eat.

Vegetables that grow above ground like broccoli and cauliflower are acceptable! Also, leafy greens like spinach and kale (which is great for today’s low carb keto soup recipe)!

Avocado, nuts, and seeds are also good choices and make great snack options.

High fat dairy. Praise God at least there is something good about a keto diet, haha. Hard cheeses, high fat cream, and butter get the thumbs up!

Stevia is an acceptable keto-friendly sweetener.

Unlike a traditional zuppa toscana soup, you’ll want to replace some of those high carb ingredients in today’s recipe.

Start by swapping out the potatoes by using cauliflower. Yes, you’ll know it’s not a potato when you eat it. But, zuppa toscana soup is packed with flavor, and the cauliflower absorbs some of that flavor while also providing a great substitute for potatoes.

Using a large soup pot (like this dutch oven), brown your sausage and bacon together. I chose a mild Italian sausage (without the casings) and a thick sliced bacon. I chopped the bacon BEFORE cooking it to help speed up the process of cooking, and making it easy to assemble and eat.

Add in beef bone broth (or beef stock or beef broth) to your cooked sausage and bacon. Why bone broth? I choose bone broth because it contains collagen which is GREAT for my joints (remember: CrossFit). It sounds gross, but it essentially tastes the same as beef stock or regular beef broth. You could also use chicken broth, chicken stock, or chicken bone broth instead of the beef flavor. Or vegetable broth for that matter. I found that the beef broth has the richest flavor for today’s soup!

Next, add onions, garlic, and cauliflower. For the cauliflower, try to remove as much of the stem as possible, for best flavor. I used one whole head of organic cauliflower.

Cover your dutch oven and cook for about 15 minutes, until the cauliflower is tender. Add in heavy cream and spinach. Yes, the true Olive Garden Zuppa Toscana Soup recipe contains kale. But you guys, I just don’t like the flavor of kale. If you love it, use it. I chose spinach instead because my family LOVES this veggie!

Serve this soup with a sprinkle of Parmesan cheese and enjoy!

    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.

  10. Courtney O'Dell

    This soup is full of flavor and so easy! Love it 🙂

    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!

  17. Juli braby

    I just made this in my instant pot because I was using my stove to make fried chicken for my husband 😂. Used 1/2 chicken breast and 1/2 # sausage. Cooked 5 minutes (will try 2 min. ) next time after sautéing. Added kale when pressure dropped and let it cook in the hot broth while I finished his meal. Also used chicken broth because that was what I had on hand. Definitely a keeper. Thanks for the recipe.

    I made this for the second time today and really like this soup. I doubled the recipe and used a full 1 lb package of bacon because I didn’t know what to do with the other 6 slices and bacon is delicious. For the first time I also made homemade chicken stock. I put all the skin and bones from a 10 lb package of chicken thighs in my instant pot with a large onion, head of garlic, carrot, 2 in piece of ginger, thyme, salt, peper and 3 qts water and pressure cooked for 40 minutes with manual release. Once cool, strain out solids and seperate the fat. It turned out incredible, easily one of the top 3 soups I’ve ever had.

  27. Thank you very much for a good recipe, I will cook it for the whole family for dinner. Thank you, it looks delicious!

  28. Randi Singleton

    Oh my goodness! I made this tonight and its AMAZING ❤ I added mushrooms in with my sausage and that’s the only difference I made. Absolutely delicious!!!

    Delicious! I did 2 different batches in the instant pot. One for 3 mins high pressure quick release and one for 2 mins high pressure quick release since the cauliflower got a little mushy, but was still great. Added the kale and some spinach mixed and cooked on sauté for about 5min. Worked great! Thanks!!

  37. Thank you so much for posting this recipe! I love the original version and knew I’d see this copy-cat version online. This turned out super delicious and better than the original in my humble opinion. I knew I skewed my net carb results, but I added half cauliflower, half broccoli, and a small zucchini chopped, and used chicken broth instead of beef as it’s what I had on hand. It will be on weekly meal rotation in my house from now on. Thank you for this one-pot wonder!

    I just made this last night and it was AMAZING. However, I did change one thing: instead of browning the sausage first and adding the onion and garlic, I started the whole thing by sauteeing the onion and garlic first in a 1/4 stick of butter first for about 12 minutes, then added the sausage to brown together. Sauteeing allium cuts that sulfur profile down and brings out a whole other level of flavor. Highly, highly recommended!

  46. Megan Aguilar

    LOVED LOVED LOVED it!!! Next time I am going to add another 32oz of beef broth, only use 2 strips of bacon, drain the grease from the meat, double the cauliflower, and quadruple the spinach. I just cooked it and I stuck to the exact recipe except I put in 48oz of beef broth (all of my container) and I quadruple the spinach because it shrinks up so much. My entire family loved it!!! Will absolutely be making this again!

  48. I made meatballs with hot italian sausage and a bit of ground chuck. I followed the recipe and it smelled delicious and tasted great as well, right up until it said add heavy cream. I did add some heavy cream, but I felt like I could have omitted it, as I preferred the taste of of the plain beef stock. Will make this again, but without the heavy cream.

  49. Steve Barnes

    I am making the zuppa soup now. Should I drain the sausage once it’s cooked?

    This soup is freaking awesome! Keto or not, it is simply delish! I used some of my home made chicken stock, but added 2 beef bullion cubes in place of any salt…the flavor combo was amazing. I used the thick sliced bacon…it was almost like eating pork belly in the soup! The only other change was to add some Italian seasoning (about 3/4 tsp). to complement the Tuscan flavors. And don’t skip the grated Parmesan on top. Hubby is already asking for it again!

  53. Mel

    This is great for someone who is following a low carb diet, but not for someone who is following a ketogenic diet. I am alotted 13 net carbs per day, so one serving of this soup leaves me no room for error. Most keto macros will not allow for more than 20 carbs per day. Also, I don’t understand how there is no fiber in this. Both spinach and cauliflower contain fiber, which would lower the net carb amount.

    This is delicious.  I did make a couple of minor change that does not affect the over taste but does cut the carbs a little.   I used only half the head of cauliflower and substituted in 1 cup of slices fresh mushrooms as they are lower in carbs.   I also put the onions and garlic in with my meats when browning instead of afterward.  The broth is so rich and flavorful.  Don’t add extra salt to this until you taste at the end as beef broth can get salty.  Oh yeah, I did add a little extra cream at the end as well.  it just seems a little watery so I added another 1/4 cup cream.  When you have been doing Keto for awhile something like this taste like nectar from the gods!  I will definitely be making it again.  Thank you for posting!
