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.

This is SO yummy! I decided to brown the bacon in the pot so I could have the additional flavor from the bacon fat to sauté the veggies in….a great comforting pot of soup! Thanks!
OMG, you are brilliant! Now I’m wondering why you didn’t think of that. So glad you enjoyed it!
Wow! Made this soup exactly as written. So good and so flavourful!
So glad you enjoyed it; thanks for taking time to tell me!
Made a 1/2 batch of the recipe as directed (with milk) on the stove top and pureed it my my Vitamix before transferring back to stovetop. It was really good! Very easy to make and the directions are easily followed.
Very similar flavor profile to potato soup but with a better, silky texture (I like cauliflower 100xs more than potatoes anyway). Thanks for the new recipe-it’s being added to my rotation!
Thanks for sharing how you did it with the Vitamix; so glad you enjoyed it!
All of your recipes look so yummy! Thank you for explaining the steps in detail! Thank you for sharing this recipe!
Thanks, glad you like it!

Have you trie freezing this?
I have an upcoming procedure and need soft foods. I was hoping to be able to freeze and thaw out when I needed it!
Thank you!
I really think it will freeze, but I haven’t tried it. Would love to hear how it works if you try it. And good luck with the procedure!
Did you freeze it and if so, was it ok?

I do not have an instant pot or a pressure cooker,but I do have a vitamix blender and this recipe was awesome cooked in my vitamix blender.
Great to hear that. I don’t have a Vitamix, but I’ve heard good things about them.
How did you modify the recipe cook time (and ingredient wise if you did since onion and garlic can overpower with a Vitamix)? I love cauliflower and my Vitamix and want to use it more!
We made this tonight and it was amazing! Thank you so much.
So glad you liked it!
My hubby and I are camping in MI right now and I've saved this recipe to try on this trip! It's cool outside and today is a good day for soup! It's in my IP right now…cannot wait to have it soon!
I love the idea of camping with the Instant Pot, hope you enjoy!
I just discovered your site, and find so many recipes that I want to try out, thank you so much. I do have a question here, can I use heavy cream instead of the half&half, because I never use this, and I always have heavy cream in my fridge.
Glad you like the recipes! I haven't made this with heavy cream, but I can't imagine why it would not work!
Quick question… when you say quick release the pressure, do you mean to cook and then quick release or have it on the quick release setting while it cooks? Newbie IP user here ???
AnnMarie, you always have the lid locked to prevent steam from escaping when you pressure cook. Quick release means that once the time is up and the Instant Pot has counted back to zero time left, you move the steam valve to open so the pressure can quickly come down. (Use a wooden spoon or something to keep from burning yourself) Here's a good post from my friend Barbara about the difference between Natural Pressure Release and Quick Release.
BTW, hope you enjoy AnnMarie!
Ah yes, that makes sense, can't really pressure cook with an open steam valve! LOL! Didn't really think that one through before I asked my question. Thanks for the reply! I'm making this tonight 🙂
Has anyone tried it with frozen cauliflower instead of fresh? It is hard to get fresh cauliflower this time of year that is affordable…
It might work with frozen cauliflower but I am not able to tell you how to adapt the recipe, since I haven't tried it that way. Let me know what you think if you try it.
I'm so glad I followed your advice to make a double batch. So, so good!
So glad you liked it Monica!
Just visited your website. Nice healthy food. I usually look to whitefish for low carb diets, but your suggestions are great. Thank you for sharing.
Glad you like the site!
Will made it tomorrow for dinner, It looks and sounds good!
Hope you like it Alma!
Thanks for share the recipes. I want to try it..
Hope you enjoy!
Hi Ms Kalyn! I've followed you for years, and have enjoyed every moment. I've been looking for the "yum" button on your page and can't find it. Where is it??? "Or if you're a member of Yummly, you can use the Yum button on my site to save the recipe and see the nutritional information" Thanks!
Hi Em, so glad you are enjoying the recipes! The YUM button is at the top of the post, in the row of buttons that starts with Pinterest. I think you might have to sign up at Yummly.com (or maybe it will prompt you to sign up the first time you click it.) I will warn you that the Yummly nutritional info isn't always 100% correct, but usually it's good.
Even though it's cauliflower (not my favorite!), I have to try any soup that has this much cheese. And I love to use my Instant Pot, so thanks for creating a recipe for it.
Lydia, try really sharp cheddar!
I must just be missing it, but how much half and half?
Oops, I guess that is what happens on a day I try to quickly write up a recipe while I'm getting ready for a Superbowl Party. So Sorry, should be 1/2 cup. I will fix right now!
