This low carb and cheesy Broccoli Cauliflower Rice Chicken Casserole recipe is perfect for dinner and makes great leftovers. It’s also gluten free!
It may shock some people to hear this, but casseroles were never really a part of my childhood. Sure, there was the occasional attempt at making lasagna and maybe a hamburger helper type of dish, but that was rare. (Wait – are lasagna or hamburger helper even considered casseroles? No clue. See, that’s exactly my point.)
Though my family liked all the ingredients in the typical casserole, we didn’t like them all mixed together. We wanted the ingredients separate just so we could assemble them on our own plate. Think about it – rice, beans, cheese, a protein, salsa and corn tortillas. All those ingredients would make an amazing casserole. But instead we wanted to make our own thing like tacos, tostadas, sopes, you name it.

Oh well. Those are pretty tasty, too. 😉
It wasn’t until I moved in with John that I realized the power of the casserole.
- Usually, very few pots and pans are required. Less dishes to wash equals a win in my book, because let’s get real – washing the dishes after getting home from work is the last thing John and I feel like doing.
- Most importantly, casseroles are often huge! Which means lots and lots of leftovers. If we didn’t feel like cooking the next day, no worries – we’ve got some leftover casserole. SCORE.
Like many people, John doesn’t always like eating vegetables. And because I love him and care about his health, I’m always trying to come up with new ways to incorporate more of them into our meals.
And that’s where cauliflower rice comes in. If you’ve never made “cauli-rice,” prepare to have your mind blown. Here’s what you do. Ready?
How to make cauliflower rice
- Grate a head of cauliflower using a large cheese grater, or lightly pulse cauliflower florets in a food processor.
That’s it! It’s a brand new way of enjoying cauliflower that kids even like! If you need more of a step-by-step tutorial, check out my recipe for Mexican Cauliflower Rice.
Aside from all the “hidden” veggies in this dish, my favorite part of this Broccoli Cauliflower Rice Chicken Casserole is all the cheese!
4 cups of shredded cheese to be exact. Some people may not think that’s enough, so if that’s you, go for it. Sprinkle some more in there.

Loved it. Making in again tonight. I made it for a friend that just had a baby that’s gluten free also!! It’s a hit! ☺️♥️
My son LOVES this recipe, even requested me to make it for all his friends he had to the house for his birthday party. It is definitely a family go to for a nutritious meal that all will devour.

Hi! So glad you enjoyed the recipe! Nutritional info can be found under the recipe card.
This tastes so creamy! Was a hit with my husband!!
This is absolutely delicious!!!
Ummmm…yum!! So easy and super tasty. I needed something to fix for a neighbor, but didn’t want to send before trying it. It was a hit in my house! In fact, I just finished the last bite of leftover. The only thing I’d do different is cook it 20-25 minutes vs. 50. This would do well to fix ahead and freeze. Thanks for sharing!
