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 carnitas, chicken tostadas, sopes, you name it.
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.
