Ingredients needed
Making this keto kielbasa soup with cauliflower is so simple. It has low-carb and high-protein ingredients that will fill you up.
Here's everything that goes into this quick and easy broccoli cauliflower soup recipe:
Sausage
The first ingredient is chopped-up sausage. I like how the different sausages really up the flavor of this soup. I use a mix of Bockwurst, Schublig, and Hungarian sausage for this recipe.
You can use any type of sausage that you like - kielbasa or Polish sausage would taste amazing too!
Veggies
As the name implies, this soup has both broccoli and cauliflower in it. You can use just one of them without changing the taste or texture of the soup.
Bacon
Hey, don't even think about skipping the bacon! Trust me, it's one of the absolute highlights of this soup!
Now, if you're doing keto, just make sure to go for bacon that isn't maple-cured or has any added sugar.
Creamy broth
To make the thick and creamy broth, I added heavy cream to the chicken bone broth. Bone broth is usually creamier than just chicken broth, but if you can't find any, you can use chicken stock instead.
Cheese
Add more cheese to it too! Both yellow and white cheddar give it the best taste and color. It's totally fine to just use yellow sharp cheddar cheese. In fact, you can use any type of cheese that you enjoy.
Please note: Check out the recipe card at the bottom for a full list of ingredients used to make this low-carb recipe.
Soup tips:
- Want a creamier soup? If you want a creamier soup that doesn't have as many chunks in it, use double the amount of broth, cream, and water. When you double that, it will serve 10 people.
- Prep the veggies ahead of time. To speed up the recipe prep, you can pre-chop the broccoli and cauliflower or use frozen pre-chopped veggies.
- Make this soup vegetarian. You can easily swap out the sausage and bacon for a plant-based option. I bet this would taste delicious with Mexican soy chorizo! Trader Joe's has a delicious one.
How to make broccoli cauliflower cheese soup
Whipping up a batch of this cauliflower and broccoli soup with cheese is so simple. It only requires one pot, too! Follow this step-by-step tutorial on how to do it.
Step 1: Simmer the chopped veggies
One of the great parts about this broccoli and cauliflower soup is how easy it is to prep.
You’ll simmer the chopped broccoli and cauliflower right in the broth for 4 to 5 minutes, then set aside.
Step 2: Cook the sausage
Meanwhile, brown the sausages in a large skillet with olive oil, then set the sausages aside.
Step 3: Make the creamy broth
In the same pan over low heat, add the cream, water, and butter, then stir until the butter is melted. Add the cheese and stir slowly until fully melted.
Step 4: Let the soup simmer
Add the cooked sausages back in, then pour in the broccoli, cauliflower, and broth. Season, cover, and simmer for 5 to 8 minutes, stirring occasionally.
Step 5: Serve and enjoy!
Top with bacon and serve.
What to serve with keto cauliflower cheese soup
You don’t need much more than the soup to make a complete meal, but you could always add a side salad or some low-carb bread to dip into the creamy broth.
For a bit of a crunch, top the broccoli cauliflower soup with some homemade keto croutons!
Tips for making the best low carb broccoli and cheese soup
- If you prefer a smoother soup, blend half of the finished product in a blender before serving.
- For extra protein, add cooked shredded chicken to this soup. It's also a great way to use up any leftovers you have!
Frequently asked questions
These are the questions I get most about making keto cheesy sausage soup. If I don't answer your question here, please leave it in the comments down below.
Nutrition will always vary based on the exact ingredients you use. For me, I split this recipe into 10 servings, with each serving coming out to 6 total carbs and 1 gram of fiber, or 5 net carbs.
Most of the carbs in this cauliflower broccoli soup recipe come from the vegetables. I keep the serving to a cup size to keep the number of carbs manageable.
Because this soup is packed with so many hearty ingredients, the 1-cup serving size is usually plenty!
I used a mix of yellow and white cheddar cheese, but you can use any type of cheese that you enjoy. Just make sure to use a high-quality cheese for the best flavor and one that melts really well.
I bet that this would be excellent with Gruyere or Monterey Jack too!
Yes, you can definitely use frozen broccoli and cauliflower in this soup. Just make sure they are thawed and drained before adding them to the soup.
When I prepare this recipe, I like to mix together:
- Onion powder
- Garlic powder
- Mustard seed
- Marjoram
- Thyme
If you haven’t heard of marjoram, this spice is a cousin of the oregano family. In Germany, it’s popular to use along with thyme in sausage recipes. Since this soup features sausage as a prominent ingredient, marjoram is a great fit with these flavors.
If you don’t have marjoram, you can substitute it with sage, thyme, summer savory, or basil.
Another spice not everyone has on hand is mustard seed. Mustard is made by mixing ground mustard seed with water and vinegar, so if necessary, you can substitute regular mustard in this recipe!
Make sure the soup is chilled before you store it. You can keep cauliflower broccoli cheese soup in the fridge for up to 5 days.
Yes and no. Part of this soup recipe is safe to freeze, while others (like the dairy products) should be left out till you are ready to eat.
You can prep the veggies and sausage in advance to make a freezer kit. When you are ready to cook it, dump the freezer kit bag into a pot and follow the rest of the instructions to make the creamy broth.
Just be aware that the veggies may get a little mushy during the freezing and thawing process. As long as that doesn’t bother you, then you can certainly store this soup for longer periods of time.
If you choose to freeze the broccoli cauliflower soup, it should last for several months.

Sandra
Looks great. Can I have the recipe now?
Deanna Calderon
So good!! I doubled the recipe and added some Italian cheese blend as a garnish to the top of it.
Lynn M
4 stars isnt bad but I (only my opinion) think the spices are off. It isnt wrong, just off a bit. Probably my pickiness. I doubled the sauce since I was wanting soup and it turned out beautifully. Also got a bit confused on directions between step 4 thru 6. My vegs were set aside but yet it says in the "same saucepan" to add cream and water...I used a drainer then added the liquid back to the pot and continued on so I could add the cauliflower/broccoli later. All was figured out so the soup hit the spot. Great meal for the cold winter weather. Im certain it will be added to rotation.
Tiffany
Do you use mustard seeds whole or ground?
Jessica
Do you have specific suggestions for making in a crockpot or could i make it the night before and warm it up in the crockpot the next day? Wasn't sure with the heavy cream.
Thanks!
C. Ward
The soup was delicious! I doubled all ingredients, including the cheese. I didn’t have any mustard seed on hand this time, but I probably would try mustard seed oil in its place next time.
Sandy Tally
I’ve made this so many times, with a few omissions and variations, but it’s so good! I nearly always have a pot of this in my fridge.
Krysta
Very good tasting so glad I made it will happily make again and again. So thankful. Getting ready to try the cream of asparagus soup recipe next.
Greg Divine
This soup was amazing! We’ll be making this one again and again. My Wife was very impressed and still talking about it as am I . Very filling and flavorful. Had to let you know and give you a big thumbs up and thank you. Can’t wait to make more of your recipes.
Judy Vaughan
Entire family loves this recipe and is better the second day. However, recipe has omitted when to add the bacon when preparing.
Lisa MarcAurele
It's added at the ends with the remaining spices and seasonings.
Joyce
This is pretty great. I did remove half of the veggies and blended the broth/cream/water/cheese/veggies to make it more of a chowder. Then I added back the rest of the veggies and the sausage.
Austen
Soup turned out great. I added half a cup of leek, half an onion, three cloves of garlic and used all chicken stock and no water. Also I used hot Italian sausage. Will definitely make the soup again.
Tammy
This soup is greattttt!!!!!! I used Cajun style smoked sausage and it gave it a little kick. Has anyone tried substituting chicken? I may try that next time.
Lisa MarcAurele
You can really use any meat you'd like in the soup.
Jenna
My husband and I loved this recipe!
I subtracted the onion powder with sauted onion and i didn't add bacon because it was salty enough with smoked sausage.
Colleen
My husband and I love this soup, and we are making it again this next week. I love how easy and flavorful it is, and it freezes well.
Katie
This soup is soooo yummy! Even my picky daughter loved it and wants me to make another batch????...Thanks for posting ????
Becky
Soup was very good and entire family loved it. Could the liquid measurements be updated to reflect 10 servings? 1 cup broth, 1 cup cream, and 1 cup water will not serve 10 as this recipe indicates.
Lisa MarcAurele
For less chunky soup and more liquid the liquid should be increased. Will note that.
Shelly
Ah-mazing!!!! So delish. I didn’t even have the bacon and I didn’t miss it at all. My company loved it and the fact that it was lower carb! Also, leftovers were just as good if not better!
Stacie Woodard
Just made this using smoked sausage. Fantastic! It's going to be a regular in the lineup!
Marilyn
Do you know if anyone has used frozen broccoli and cauliflower?
Lisa MarcAurele
They should work out okay, but may get a little softer after cooking.
Dan
I'm stunned by the flavor and how filling this soup is. Absolutely a new favorite. Only added 2 extra strips of bacon. Everything else is by recipe. Thank you for the share.
Michelle
Have you ever made this in the instant pot?
Lisa MarcAurele
I haven't, but I do know that dairy can curdle under pressure so if you give it a try, might want to add in the heavy cream and melt the cheese after it pressure cooks.
Sherry
Omg, best soup EVER! Thank for such a great recipe
Stacey Davis
Loved it
Connie
Very good! I cooked it a little different all in one big pot. Husband really liked it. I didn't have very much sausage but I had some cooked diced ham, browned it with the sausage. Anyway was very good. Will make again.
Lorie
I made this for family.. everyone LOVEDit! Thanks so much!
Joan Haley
Made this for dinner tonight and it is so good. The broth was wonderful. We all loved it. I will be making it again. Absolutely delicious.
Christine Kirchner
The broccoli cauliflower cheese soup is fantastic
WOW
Deb
It was delicious! I used turkey sausage and I doubled the recipe! I didn’t double the sausage though!!!! Making it again this week!!!!
Shirley
Does this soup freeze well
Lisa MarcAurele
It does. It should last several months in the freezer.
Jeanne
OMG! This soup is amazing! I put the bacon in and cooked it with the sausage, used another cup of broth and used Dijon mustard instead of the other. Love it!
Wendy
This is the best cheesy broccoli/cauliflower soup ever!!!
Lisa MarcAurele
I agree! It never lasts long in my house.
Afton
I couldn’t find my marjoram Publix probably has it but I went to the grocery store near my home. What could I use in place of that or would it make a difference if I didn’t use it at all?? Thanks in advance and looks delicious can’t wait!
Lisa MarcAurele
It's a type of oregano so you can use regular oregano instead.
Stacie
I used Italian seasoning.
Dawn
THis soup is so good I can eat it cold! Will be making it for life.
Lisa MarcAurele
It's definitely a winner with my family and friends too!
CJ
Wow what flavor!
I took my immersion blender and just a quick bit to entice it to be thicker. I didn't do it for a long period, just got some of the cauliflower and broccoli into smaller bits.
It worked great!
We will make this again this fall/winter!!!
Shanna
I have made this on a few occasions. Last night for a large crowd. Everyone loved it and there were definitely not any leftovers.
Heather
Can you make this in a crockpot?
Lisa
You can, but I'd add the broccoli and cauliflower towards the end so they don't get mushy.
Jessica
Do you have specific suggestions for making in a crockpot or could i make it the night before and warm it up in the crockpot the next day? Wasn't sure with the heavy cream.
Thanks!
Kim
Olive oil is listed but I don't see it added.
Lisa
It's used to brown the sausage.
mary kemper
can I use ham instead of bacon and sausage
Lisa MarcAurele
Some diced up some ham would be a good sub.
Kelly
I'm going to make this week end and was wondering if it is freezable?
Lisa
It should be fine to freeze based on ingredients, but I haven't tried it.
Kailey
Was feeling very lazy but wanted a comfort soup for this chilly fall day. Decided to just dump all the ingredients in a pot (after precooking my sausage in said pot) and let it simmer for an hour. So so yummy and so easy. Thanks for the great recipe!
Lisa
You're welcome Kailey! Glad you enjoyed the soup.
Emma
This was really good. I didn’t discard the chicken broth but kept it and mixed with the cream during that stage of the recipe. I also found that I needed to add additional broth once cooked, because it became almost too thick (probably tripled the total broth amount stated). I also subbed ground mustard for the mustard seeds and it was delicious. It’s good with paleo breakfast sausage in place of the kielbasa style sausages. The portions stated are a little over a cup - so, check the numbers if you’re trying to stay in ketosis, and adjust the portion size accordingly.
Lisa
Good tips!
Amber
I made this tonight with smoked sausage and Monterey Jack cheese (it was what I had in the fridge). It was delicious!! Will definitely be making again!
Lisa
So glad you enjoyed the soup Amber!
Gerard Webster
After it was done cooking I added a bag of make to get some more vitamins and nutrients and it was delicious.
Megan
Made this with a few tweaks, probably quadrupled the liquid amounts, I also only used one pot, cooked the bacon, then browned the sausage, left the bacon and sausage drippings, added broth and veggies, steamed until almost mushy, blended the veggies/broth until smooth. Added the cream, cheese and sausage and let simmer for a little while. Topped with bacon and green onion. Tasted amazing and tricked my hubby into eating something healthy!!!!!
Nicole
Hi! Great recipe! I purée about 3/4 to get up to the thick texture that my family loves (more potato-ish). I’m wondering if you’re “served 10” is consistent with the nutrition info. We got 5 bowls out of this, so that would mean doubling the info. Which seems high to me for the ingredients...feedback would be helpful! Thanks again. Yum!
Lisa
Because this has a lot of vegetable carbs, I keep the serving to a cup size.
Rachel Flossie
When I put the recipe in my fitness pal exactly as listed I get 17.2 carbs per serving. How did yours calculate so low? I’m scared I’m over carbs now.
Lisa
I just rechecked the calculation and got similar values. You do need to be careful using MFP. Often, the ingredients are wrong.
Sabrina
OMGummy!!! I used the same ingredients except I did not have marjoram nor mustard seed. Added some various Italian herbs and a tablespoon of Dijon mustard instead. I also layered the ingredients different from the instructions. This was AmazeBalls good! I did a slight tablespoon cornstarch slurry with water to thicken the soup up. I'm fine with 9 carbs to thicken up a whole pot of soup. Pick and choose your battles.
Thanks for the recipe. Posting this to my various board, like LowCarb and Tried & Approved.
Lisa
Thanks for sharing the recipe Sabrina!
Jen
I use xanthan gum as a thickener! You still get that thick consistency but you do not add the extra carbs!
Karen
Okay, I didn't find anyone asking this question, so I will. What kind of "sausage" did you use in this recipe? Was it Kielbasa, or Italian sausage? I was thinking both would be good, but the mild Italian would add more flavor.
Lisa
The sausage used is at the bottom of the recipe. You can use any sausage, it doesn't have to be the same kind.
Paulette
I used regular kielbasa, also omitted the spices because I didn’t have them and it was delicious!
Kenzie powderly
Are you supposed to drain the broth before adding the cream and butter?
Lisa
The broth mix is set aside (in another pot or container)
Kenzie powderly
Do you add the cream butter and cheese to the saucepan with the veggies and broth already in there? Or did you remove the veggies and broth then add it back in?
Lisa
Without the veggies and broth.
cindy corley
Okay, so this soup is AMAZING. I cooked it just as the recipe said, and i am telling you, it turned out SO good. I didn't have a scale, so wasn't sure how much broccoli and cauliflower to put in - as it was, i probably skimped a little on them and will for sure add more next time......but KETO or not, you have a winner! Thank you for the recipe. Looking forward to having it again soon!
Lisa
Thanks for letting us know how much you enjoyed the soup Cindy!
Karen
Oh man. I think I'm in love. I'm not a fan of cauliflower so I always cream it....so I cooked it in the chicken stock and then added a cup of full fat coconut from a can of coconut milk, and water. I also added cream cheese made from cashews. Yum! I browned the sausages and added 1/2 onion and a bunch of asparagus and zucchini......and cooked that up. I added the herbs to the creamed cauliflower (and I tripled the herbs).......mixed that with the rest and I have the creamiest loveliest soup...... I will enjoy this all week as the weather chills and now I have a great cream sauce base for other soups. I'll be thinking about clam chowder....maybe salmon chowder..... Next time I'll add spinach or kale to help me get the greens in. Thank you for a most versatile and delicious recipe.
Lisa
I've cut out dairy so I'm glad to hear that the alternative ingredients worked.
Julie
Just finished making this and am not even finished eating it yet but had to stop and say how absolutely delicious this is!
Lisa
Thanks Julie! Glad you loved the soup. 🙂
Glenna
The label says 10 servings. How much in one serving? I.e. 1 cup portion?
Lisa
It's a large cup (a little more than a cup measure).
Jodi Raymond
Is a serving roughly a cup? looks amazing!
Lisa
It's about a cup size or a bit more.
Krista
Yummy! Where does the olive oil come in though? I didn't use it because I never found it other than in the list of ingredients.
?
Lisa
It's for browning the sausages.
Leah
When I copied the recipe directly from this website into my fitness pal app the carbs are drastically different. The app calculates roughly 16 carbs per serving. Any thoughts?
Leah
It is absolutely amazing tasting though!
Lisa
You'll need to look at each ingredient that was selected in MFP. They are user inputted and some may be inaccurate.
Carly
Every time I look at My Fitness Pal, they are wrong on carbs. Compare to your ingredients because every time I look through them, they are way off
Robynne
Use a different sausage, and pay attention to carb intake on broth
Stacie Wilson
This looks SO good. Perfect for fall weather too. Definitely going to try, thanks for sharing.
Ellen Phlieger
I've made this recipe several times it's one of my favorites I use many recipes over and over they all seem to turn out perfect
Lisa
Awesome Ellen! So glad you liked it.
Anne Tisdale
What kind of sausage did you use? Pre cooked kielbasa or uncooked?
Lisa
It was a mix of uncooked sausages as listed in the recipe notes.
Marilyn
I made this tonight. The flavor was good but the cheddar cheese became one big lumb of cheese....even though I put it in grated and in small portions ?
Lisa
Some brands of cheese are a little different. Ours did not clump.
Carolyn
I have read in other recipes to add the cheese very slowly, a little at a time, to prevent clumping. It worked for me.
Matt B
This recipe looks good I think it will be dinner tomorrow. I would think that you would get more sausage flavor if you cooked the sausage, removed it, then added the stock and water scrape the bottom of the pan, then veggies and finish with the cream cheese and spices.
Lisa
That's probably true!
Vickie
I was wondering if this soup will freeze well? Thanks for all the low carb recipes- you are a great resource and inspiration!
Lisa
The broccoli and cauliflower may get mushy after freezing. If that doesn't bother you, it should be okay.
Linda
Why drain that tasty broth after cooking the veggies? Why not use the broth as part of the soup's liquid?
Lisa
Agree! That's a mistake that I didn't catch. Thanks for noticing!
