How to Make Broccoli Cauliflower Chicken Casserole {Quick Overview}
This is just a quick overview of some of the steps involved in making the low carb casserole. For the recipe in detail, including exact measurements used at each step, scroll to the recipe card at the end of the post.
Preheat the oven to the temperature listed on the recipe card (at the end of the post).
Now, it’s time for veggie prep! 🥦
To prep the broccoli: Place broccoli florets in a microwave-safe bowl, drizzle with 3 tablespoons of water, and cover the bowl with a microwave-safe plate or lid. Microwave on high for 3 minutes, then carefully remove the plate or lid, drain any extra water, and set aside.
To prep the cauliflower (do this while you’re prepping the broccoli): While the broccoli is steaming, prepare the cauliflower rice according to the package instructions. Drain any excess water and set that aside too.
In a large bowl, mix together the broth, heavy cream, sour cream, Italian seasoning, salt, pepper, thyme, and 1 1/2 cups of shredded cheddar cheese until it’s all combined.
⭐ TIP: For the best texture, shred your cheese by hand. Pre-shredded cheese contains anti-caking agents that keep the cheese shreds from fully melting.
Toss in the cubed or shredded rotisserie chicken and mix it up well. Then add the steamed broccoli and cauliflower rice and stir everything together.
Spread the mixture into a 9″x13″ casserole dish.
Sprinkle the rest of the shredded cheddar cheese on top and pop it in the oven for 15 minutes.
Take it out, sprinkle on crushed parmesan crisps (or pork rinds if you prefer), and bake for another 10 minutes. That’s it!
⭐ TIP: If you don’t want to buy parmesan crisps, make your own with this Homemade Parmesan Crisps recipe. 🧀
