This recipe for my cheesy Chicken Cauliflower Rice Casserole is a hit at any gathering and is super quick to whip up, making it a favorite meal for busy days. The casserole is prepared with leftover (or rotisserie) chicken and cauliflower rice, all blended together with a delicious cream cheese sauce. Moreover, every bite of the leftovers tasted just as fantastic as it had on day one. It’s a delightful yet lighter alternative to my garlic butter chicken and rice recipe, but it’s creamy, cheesy, and juicy, just as a casserole should be.

  1. I made this recipe but I substituted with less fat cream of mushroom soup, half and half and added extra fresh mushrooms, yellow and green peppers.

  2. I’m a diabetic and hard to find delicious low carb meals. I will definitely try this using low fat ingredients also.

  3. Trying to eat healthy and made this for the first time. It was delicious! I added some red bell pepper and used pepper Jack cheese. We all loved it even the Kids loved it! 🙂

  4. Frozen cauliflower rice is one of my favorites to use in recipes but I’ve read all through your comments and haven’t seen if you strain all of the water out of it before putting it in the casserole or do you just let it go into the casserole with all that moisture?

      In this recipe, I do not cook the cauliflower rice before adding it to the casserole. So it’s just dry cali rice that is mixed together with the rest of the ingredients.

  5. Great recipe, but any ideas on greatly reducing the amount of saturated fat? It’s extremely high. Would using Greek yogurt taste good instead of cream cheese perhaps? Maybe half and half instead of heavy cream.

  6. A very good casserole. I knew I was going to like it when I even enjoyed a spoonful of it BEFORE it was cooked (used shredded cooked rotesserie chicken and frozen cauliflower rice). This is going to be a regular feature in my dinner menu for sure. I topped it with fresh sliced green onion just before serving and that added a nice fresh taste.
