Keto Instant Pot Creamy Cauliflower Soup
Making a healthy creamy cauliflower soup is very easy. All you have to do is dump all your ingredients, except the butter and cream, into your Instant Pot or electric pressure cooker.
The cauliflower will cook in with the broth with the seasoning so that it absorbs the flavor as it cooker.
Cooking Instant Pot Creamy Cauliflower Soup
To cook the cauliflower soup in the Instant Pot, close the lid and turn the pressure valve to sealing. The cauliflower only needs 5 minutes to "pressure cook" or "manual" setting. When the timer goes off, let the pressure release naturally for 3-5 minutes before turning the pressure valve to release the remaining pressure.
Next, you will want to blend the cauliflower florets with a stick blender or regular blender. You won't get the soup smooth. At this point, you just want to the big pieces to get broken up.
Keto Instant Pot Creamy Cauliflower Soup is the new baked potato soup!Finally to make the soup creamy and smooth blend in the butter and heavy cream. You will be amazed at how the texture changes with the cream. Your cauliflower soup should be thick, creamy, and full of flavor.

Slow Cooker - Creamy Cauliflower Soup
Don't have an Instant Pot or electric pressure cooker? No problem, you can easily make this soup in a slow cooker.
Just add all the ingredients, except the butter and heavy cream, to the slow cooker. You will want to double the broth when cooking in the slow cooker to account for evaporation. Liquids do not evaporate in a pressure cooker like they do in a slow cooker or on the stove.
Cover and cook on HIGH for 2-3 house or LOW for 4-5 hours, the cauliflower should be soft and tender. Then blend the cauliflower with a stick blender to break apart the florets. Add the butter and heavy cream, blend well and you are all done!
Stove Top - Creamy Cauliflower Soup
Cooking creamy cauliflower soup on the stove is much like cooking it in the slow cooker. To make the soup on the stove you will need to double the amount of broth you use to account for evaporation.
Add all the ingredients, except the butter and heavy cream, to a large pot. Boil the cauliflower covered on medium-low heat for 15-20 minutes.
Break apart the florets with a stick blender then blend in the butter and cream. If your soup is too thick you can add a little more broth, or if it is not thick enough you can allow the soup to continue to simmer until it reaches your desired consistency.
Make it Loaded - Keto Instant Pot Creamy Cauliflower Soup
Loading the soup with lots of yummy goodies before serving the best part of the soup. I love to add cheese, chopped green onions, some cracked pepper, and paprika.
However, have fun with your toppings. You can add bacon bits, sour cream, or any other keto/low-carb options.

Can you substitute the heavy cream for a dairy alternative if so please can you provide information. Also if you don’t have a stick blender can you just put this in the food processor basically to just make it smooth isn’t it

You might like to try with your favourite dairy-free alternative, however, I cannot say with confidence how this would taste. Most dairy-free alternatives have a distinct flavour (such as almond milk or coconut cream) so it would turn into a new recipe entirely. If you do try and are successful, I'd love for you to com back and let us know.

I’m new to Keto and cauliflower substitutes and this recipe was super easy and surprisingly yummy! I didn’t even load it up like I’ve seen in other similar recipes, just a little cheese on top and it was just right.

The video shows garlic being added but I don't see anything in the ingredients list or how much to add? Does this recipe need garlic?
Libby www.ditchthecarbs.com
Whoops, thank you for finding the omission. All corrected and 2 tsp garlic crushed has been added to the recipe.
