Whole 30 Chicken Cauliflower Rice Soup

This creamy chicken and cauliflower rice soup is a soul-warming comfort food that’s perfect for rainy spring days. I dreamed it up earlier this year when I was doing Whole 30, but it’s remained a favorite ever since.

It all started when I was making Thai red curry chicken over cauliflower rice.

Cauliflower rice – essentially just finely grated cauliflower – is a little shorter than regular white rice and it reminded me of the pastina pasta that’s used in chicken and stars soup.

Even though I hadn’t had chicken and stars or chicken and rice soup in years, I immediately started craving it.

This creamy chicken and cauliflower rice soup was the answer to my craving. Plus. it was a nice change of pace from the Whole 30 roast vegetable soup that I had been relying on for an easy snack.

The cauliflower rice amps up the nutrition, and adds more flavor to the soup than plain white rice does.

Adding coconut milk to the broth makes the soup rich and creamy while keeping it Whole 30/paleo friendly.

The coconut milk does add a slight Thai vibe to the soup (a tablespoon of curry paste would feel right at home stirred into the broth) but it’s nothing too out there.

To make the soup

Start by sautéing some onion, celery, and carrot in ghee or olive oil.

You might be tempted to just throw everything in the pot, but this step is actually really important. It helps the vegetables soften (otherwise it takes for-ev-er) and helps develop their flavor.

Once the vegetables start to soften, it’s time to add the broth or stock.

Since this soup is so simple, I like to use a good quality, flavorful stock like this browned chicken stock that’s rich in color and flavor. Quality store-bought broth also works – look for one that’s roasted or browned if possible.

Bring the soup to a boil, then reduce it down to a simmer and add the chicken.

For this soup, I poach the chicken in the broth, then shred it and return it to the pot along with the riced cauliflower. I really like the contrasting texture of the long pieces of shredded chicken with the smaller pieces of cauliflower.

Add some canned coconut milk at the end to make the soup nice and creamy.

If you aren’t concerned with keeping the recipe paleo, you can also go the more traditional route of stirring a tablespoon of flour into the vegetables before adding the broth and swapping the coconut milk out for dairy milk.

  1. Amazing!! Loved every bit of it. I used a good broth and prepared the soup exactly as the recipe said, the only change I made was I used some of the prepared shredded chicken (already cooked from Costco). It was so good!

  2. We love this soup! I gave some to my friend and she blended it a little in a food processor so her 9 month old baby could eat it. He loved it! It actually tasted so good and the texture was awesome slightly blended! Something about blending it meshed the flavors differently. I make it and freeze it all the time. I thaw it out in the fridge before reheating it.

  3. This was fantastic!! To keep it lower carb I did not put in the carrots but I added a few more seasonings. Absolutely loved it!

  4. This soup was so amazing! I’m a week into the Whole30, and this recipe is a game changer. I will make this soup even after I finish the 30 days.

  5. Is it really only 1 chicken breast, as the ingredients list directs? And by that, do you mean 1 whole chicken breast? Or is it a single breast, which is how the are often sold in the store?

    • yup, just one normal portion. Once you shred it up, it’s plenty to go around in the soup!

  6. Just made this soup and it was soooo good! Thank you for the recipe, it is the perfect thing for a snowy day like we’re having
