A couple weeks ago I made a chunky chicken soup in the Instant Pot and it was so easy I decided I should make another type. Today I made a low carb creamy broccoli cauliflower soup in the Instant Pot that was dynamite! it wast thick, creamy and cheesy with little bits of broccoli and cauliflower. It’s very filling and I ended up eating it for dinner. Each bowl is only 4.7g net carbs and I’m telling you it’s satisfying and filling.

What Makes This Soup So Thick & Creamy?
Well there are a couple of things. First of all I take half of the cooked veggies and puree them and that adds thickness. I also add a little cream cheese and cheddar cheese which makes it creamy and also adds to the thickness.
Low Carb Creamy Broccoli Cauliflower Soup Recipe
- Add chopped broccoli and cauliflower to the Instant Pot along with chicken broth and Better than Bouillon. I’m mentioned many times that this gives SO much flavor to the soup but if you don’t have it you can try some standard bouillon.
- Also sprinkle in your garlic and seasonings, mix and pressure cook for 5 minutes.
- Quick release the steam and take out half of the soup and puree it in the blender.
- Then pour it back into the Instant Pot and add the cream cheese and cheddar cheese.
- Whisk until the cheese melts and everything is combined.
If you want you can add in extra veggies to have a more chunky soup or you can puree them all for a smoother soup.
I highly recommend this Instant Pot and a Vitamix blender for puree soup. It makes it silky smooth and I use mine every single day. Seriously between, bullet proof coffee and smoothies I use it daily.

This looks delicious! Can you use frozen veggies?
Denise says
Hi Tina, I don’t see why not. The only problem I can see is that it will add a little more water to the soup. So maybe add a little less broth. Like a few tablespoons less of the broth. Good luck and I hope you like it!

Loved it! Made it exactly as the recipe but added a tbs of “recado” (a blended mixture of onions, garlic, green peppers, sweet ajíes, cilantro o cilantro leaf which I have on the ready in the fridge). It was delish! Garnished with bits of bacon. Easy and fast lunch.
Denise says
That sounds delicious Madeline! So glad you liked it.
Lina says
This was easy and delicious. My husband eats keto, and my daughter and I do not, so this was a great compromise for all of us. I made it exactly as written, other than adding a small glug of white wine at the beginning, which really perked up the flavor.
Denise says
Hi Lina, so glad you all liked it. I’ll have to try the wine next time. Thanks for coming back to rate the recipe. I really appreciate it!
