Instant Pot Low-Carb Loaded Cauliflower Soup is an amazing dinner idea when it’s cold outside and you want a treat that won’t remotely make you think about carbs! And even people who are normally cauliflower avoiders will enjoy this delicious low-carb soup!
When I created this recipe with my niece Kara, we absolutely could not wait to share it with you! And now that it’s several years later and this recipe has turned into one of the most popular recipes ever on Kalyn’s Kitchen, both Kara and I still make it regularly, so today I’m reminding you about this tasty soup for Friday Favorites. And it’s just in time for serious soup weather, are you ready for that?
We made the soup in my 6 Quart Instant Pot (affiliate link) and our only regret was that we hadn’t made a bigger batch. If you have an 8 Quart Instant Pot (affiliate link) you could double the recipe for Instant Pot Loaded Cauliflower Soup if you’d like. For those who haven’t caught the Instant Pot fever just yet, I’m going to give stovetop direction as well, because this soup would be super simple to make on the stove.
How to Make Instant Pot Low-Carb Loaded Cauliflower Soup:
(Scroll down for complete printable recipe with nutritional information.)
- Chop up the onion and the cauliflower.
- Melt butter or heat oil in the instant pot on the SAUTE setting and cook onions for 2-3 minutes.
- Then add the chopped cauliflower, chicken stock, garlic powder, and salt.
- Lock the lid, use the MANUAL setting and cook on HIGH PRESSURE for 5 minutes. Quick release the pressure.
- While the soup cooks, prepare the cream cheese cubes, grated sharp cheddar, and cream (or use milk or half and half), as well as the additional cheese, sour cream, crumbled bacon, and sliced green onions for toppings.
- Turn the Instant Pot to KEEP WARM setting and use an immersion blender (affiliate link) to puree the soup to your desired consistency.
- Check to see if you want to add a little more chicken stock to thin the soup (or reduce the liquid on the SAUTE setting if it’s too thin).
- Add the cheese and cream cheese, let it melt, and stir to combine.
- Then stir in the half and half, heat through, and season to taste with salt and fresh-ground black pepper. (Taste before you add more salt.)
- Serve Instant Pot Low-Carb Loaded Cauliflower Soup hot with grated cheese, sour cream, crumbled bacon, and sliced green onions to add at the table as desired.
This soup is guaranteed to be a hit, and many readers have reported that family members who “don’t like cauliflower” have gobbled it up.

Instant Pot Low-Carb Loaded Cauliflower Soup is a soup recipe you'll make over and over, and this tasty soup is even a hit with people who say they don't like cauliflower! Equipment: I made this soup in my 6 quart Instant Pot (affiliate link). Look at the end of the recipe if you'd prefer to just make the soup in a pan on the stove. Nutritional information doesn't include toppings since it's hard to calculate which ones and how much people will add. This recipe was created by Kalyn and Kara, after reviewing my recipe for Low-Carb Cauliflower and Mushroom Pressure Cooker Soup with Parmesan. Nutrition information is automatically calculated by the Recipe Plug-In I am using. I am not a nutritionist and cannot guarantee 100% accuracy, since many variables affect those calculations. (The nutritional info for this recipe doesn't include the optional toppings.)

I appreciate the effort Danielle went to. However the nutritional info in Yummly is much different, which illustrates perfectly why I feel it’s so hard to calculate it accurately.
If you put it through MyFitnessPal recipe maker, it comes out different, approx 9g Net carbs….
– So I guess it depends what you calculate it with. – here’s what it came out to below, with a bit more chicken stock (concentrate), and gloved garlic.

It won’t let me leave a reply under Danielle’s reply below, but this does illustrate perfectly why I am not anxious to start down the road of calculating nutritional information for more than 2,000 recipes on the site! Often I feel the Yummly information seems pretty close, but they are definitely not always accurate either. I don’t mind at all if people who take the time to calculate want to leave them here, but I can’t guarantee that any of them are accurate.

Just made thia in my instant pot…omg omg omg so good..
Thank you for aharing
Thanks; so glad you liked it!
This soup was delicious! Made it as directed, no changes needed. My whole family loved it, even my daughter who snubs veggies!
So glad you enjoyed it!
This soup looks delicious, but can you provide nutritional values? I’m keeping within a specific range of fat-protein-carb grams each day, and can’t find nutritional values here. Thank you.
I have over 2000 recipes on the site and spend 6-8 hours most days working on the blog. I’m not able to provide nutritional information for the recipes for several reasons, including the additional time it takes, the difficulty in doing it accurately, and the sheer number of recipes on my site. If you look after the recipe itself, I give two links (where it says “Nutritional Information”) for suggestions of two ways to get that information.
I just can’t edit over 2,000 recipes to add that info, and I know once I do it on one recipe people will expect to see it on every recipe.
I believe the nutrition information through Yummly might be listing nutrition info for the whole recipe and not an individual serving otherwise this recipe would definitely NOT qualify as low carb which would be very disappointing as this recipe has become a family and friend favorite.
I agree that the Yummly information doesn’t seem accurate for this one. If you scroll through the comments there are a few readers who have shared the information they calculated. You can use cream instead of half and half if you want even less carbs.
I am planning to try this recipe but instead of using my instant pot I’m going to try making it in my vitamix.
How?
Saute onion on stove add to vitamix add the ingredients in step 2 and run until hot. Add in items from step 3 and run a few seconds to combine and serve.
I’ll do my best to return with how it turned out if it works well perhaps Kalyn can add the instructions for a vitamix as well.
Interesting idea. I wouldn’t feel comfortable putting Vitamix instructions in my recipe (since I have never used a Vitamix) but I would love it if you come back and share them in a comment if it works!
I’m interested! I was thinking the same thing with my vitamix!
Just wondering why you don’t post the Nutritional information since you say it’s low carb.

This soup is awesome!!! My family asked when are we making this again. Thank you.
That makes me so happy to hear that!
Hi everyone. I’d really like to ‘hear’ more from the people that have actually made this dish, What if anything they would change…opinions after making the dish as well as any other of Kalyn’s fab recipes.
I would love it too if people left more of that type of feedback!
Hi!!! I just started a low Carb Diet and I’m in love with this recipe but I have Lymphocitic Colitis and can not have garlic or onion. What do you recommend for substitution? I can not have onion or garlic seasoning or anything with onion or garlic in it. Thanks so much for any help!!!
Sorry to hear that, but I’m afraid I don’t have any ideas of how to get that flavor without using garlic or onion.

This was amazing I had not chicken only beef or was still perfect….even my anti keto hubby loved it woohoo…thanks for sharing !!
*had no chicken stock
So glad you enjoyed it! Good to know it worked with beef stock.
Does the recipe and directions remain the same with a soup pot on top of the stove?
Stovetop directions are in the recipe, right after the Instant Pot directions (inside the box with the actual recipe!)
I would love the nutritional value on this recipe.
