I really love this simple soup recipe because it’s low carb and makes me feel as though I’m eating a bowl full of hearty soup without missing out on that “rice” taste and feel. 

The key to making this cauliflower and chicken soup recipe work is to take the time and put some extra emphasis on the cauliflower. Some people tend to shy away from using cauliflower rice in their recipes, but if you do it right, no one will even know the difference. Since I’ve started eating low-carb, I’ve found out a few tricks for cooking cauliflower, so it really doesn’t taste like cauliflower, which is important because we don’t love it as is. This Keto Chicken and Cauliflower Rice Soup is a staple in our home!

  • Chicken – Use boneless skinless chicken breast for ease or sub with thighs. 
  • Cauliflower Rice – I use a simple steamed cauliflower rice bag from the freezer for this step. Cuts down on time. 
  • Cream Cheese – This is what adds the creaminess to the soup. 
  • Chicken Broth – You can opt for low sodium chicken broth or bone broth.
  • Heavy Cream – Adding this gives this chicken cauliflower soup a rich flavor. 
  • Cheddar Cheese – Brings out a saltiness that is a nice contrast to the richness.
  • Onion & celery – Adds flavor and texture
  • Herbs & Spices – The spices are the stars of this recipe as they infuse the cauliflower with incredible flavor to change the taste. 

Steps to make Keto Chicken and Cauliflower Rice Soup:

Below you will find abbreviated directions to this recipe. Make sure to scroll down to the recipe card at the bottom of the post for the full instructions.

Step 1: Place boneless skinless chicken breasts in a slow cooker and cover with water or chicken broth and salt and pepper. Cook on high for 3 hours or low for six hours. Shred chicken, then set it aside.

Step 3: Meanwhile, pop the riced cauliflower steam bags in the microwave following directions on the package. Then add the riced cauliflower to the pot. This next step of sauteeing the riced cauliflower in the spices and butter for several minutes infuses it with flavor and makes it taste amazing.

The use of a slow cooker makes the chicken very tender. I cover the chicken with a little chicken broth (but you could use water) and add salt and pepper. Cook on high 3 hours or low for 6 hours. If you prefer you can boil the chicken on the stove instead. Cooking in the slow cooker just makes it easier for me.

I have made this soup in my Ninja 4-in-1 Multi-Cooker so that I don’t get any additional pots dirty. Once the chicken is tender, I remove it to shred and turn my Ninja to the stovetop function and follow the rest of the recipe as if I was cooking it on the stove. (Here I show you exactly HOW to shred chicken for recipes like this one!)


Even though cauliflower is awesome for eating low carb, there are people that don’t like the taste or flavor. My low carb cauliflower hack is to fry it up in butter and spices before adding to the soup. Works like a charm! 


You can store this creamy cauliflower rice soup in the fridge for three to five days and freezer for six months in airtight containers. It may change texture a bit when defrosted due to the high dairy content but it will taste the same. 


Any type of side dish would go well with this simple ground beef dinner recipe, but here are some of my favorite side dish choices.
