This Chicken Broccoli Cauliflower Rice Casserole is classic comfort food with a healthy twist! An easy dinner with only five ingredients, this cheesy casserole will become a family favorite!

Gluten Free Chicken Broccoli Casserole

When it comes to feeding my family, I am always looking for a delicious dinner that I can make quickly without too many ingredients. That is where my Chicken Broccoli Cauliflower Rice Casserole comes in. 

With only five recipe ingredients that you can get at most grocery stores, this low carb chicken casserole is one of those healthy recipes that you can put together for the entire family. With two layers of vegetables and completely gluten-free, this is a great option for those managing Celiac disease, on the keto diet or a gluten-free diet, or anyone trying to get into healthy eating. 

The best part about this easy weeknight meal is that it takes such little prep work. Most of your ingredients are packaged and ready to go, so it is all about assembling and getting it in the oven. 

Perfect for a chilly fall day or when you’re looking for low-carb versions of your favorite recipes, this delicious Broccoli Cauliflower Rice Chicken Casserole is a great way to feed the whole family without a lot of effort. 

Recipe Notes:

• This recipe is excellent for using up leftover chicken, but there are also instructions for cooking chicken breasts below. 
• You may notice a little bit of extra liquid at the bottom of the dish after cooking, but this is normal. Between the chicken broth and vegetables cooking, the liquid may not all cook off in the oven.
• This keto chicken broccoli casserole pairs well with some bottled buffalo sauce or sour cream on top. 
• If you want an extra cheesy broccoli cauliflower casserole, top each portion with some parmesan cheese. 

How To Make Broccoli Chicken And Cauliflower Rice Recipe

Chicken Broccoli Cauliflower Rice Casserole Ingredients

1 1/2 lbs chicken breast
2 cups broccoli pieces, frozen
1 cup riced cauliflower (I used Green Giant frozen 12 oz bag)
1/2 cup chicken broth
2 cups cheddar cheese, shredded
Salt and black pepper to taste

Supplies Needed:

Large casserole dish
Serving spoon
Large skillet (optional)

Directions:

Step 1: Preheat your oven to 350 degrees and take out a large casserole dish. This will work with a large bowl or rectangular shape. Spray it with nonstick cooking spray and set it aside. 

Step 2: Cook the chicken in your preferred method. My preference is to sear them in a large skillet on the stove (like below – or skip past that part and begin preparing the cauliflower). 

How to Cook Chicken Breasts

Pour a tablespoon or so of olive oil into the pan. Season the boneless skinless chicken breasts with some salt and pepper (and garlic powder or onion powder if you’d like), and cook for 10-12 minutes on medium heat, turning them over halfway through.

Make sure that your chicken breasts are fully cooked through and then remove them from the stove and set them aside to cool for a couple of minutes.

Step 3: Once ready, take the chicken pieces and shred them or chop them into chunks. 

Step 4: Pour the frozen cauliflower rice into the bottom of your prepared baking dish. 

Step 5: Top the frozen cauliflower with a layer of frozen broccoli florets and pieces. Make sure that it is spread out evenly. 

Step 6: Top the frozen vegetables with the pieces of juicy chicken. Make sure that it is also spread out evenly. 

Step 7: Pour the chicken stock over the entire chicken and cauliflower mixture in the baking pan, making sure to pour it over as much of the chicken as possible.

Step 8: Top your chicken with shredded cheddar cheese and bake for 35 minutes.

Serve hot and enjoy!  

How To Store Leftover Chicken Broccoli Cauliflower Rice Casserole

Store any leftovers in an airtight container or the baking dish sealed well with aluminum foil or plastic wrap in the refrigerator for up to 3 days. 

Can I Use Leftover Chicken In This Low Carb Broccoli Casserole? 

Yes! This is a great recipe for using up any cooked chicken you have on hand. If you have leftover rotisserie chicken, chicken breasts, or even boneless chicken thighs, shred up the meat and add it. Particularly on busy nights, having cooked chicken that you can use will save you a lot of time.

If you have leftover cheesy chicken, you can use that here as well. During your meal prep for the week, plan to make your cheesy chicken with mozzarella cheese, sharp cheddar cheese, or Monterey Jack cheese, and use the leftovers here. You’ll be adding cheesy chicken to a dish that basically creates more cheesy chicken! 

Can I Add Traditional Rice To This Chicken Casserole?

Yes! You can easily cook some regular rice and add it to the bottom of this easy casserole.

The main reason that I left it out of the original recipe is because of the time that it takes to cook and add the rice, but if you have picky eaters that you think may enjoy the texture more, go for it. Many gluten-free casserole recipes contain rice (there is no gluten in rice), so it is an easy gluten-free add to make. 

Can I Use Fresh Vegetables Instead Of Frozen? 

Maybe. Unlike other popular recipes, this gluten-free chicken casserole is designed to use frozen vegetables. They take less time and have just as much flavor when cooked.

That said, if you use both fresh broccoli and fresh cauliflower rice (You can take cauliflower florets to a box grater to make your own cauliflower rice), it is easy enough to make that swap and reduce the cook time slightly.

I wouldn’t use one frozen and one fresh though, or you may end up with overcooked and undercooked vegetables in the same dish. 

Can I Add A Cream Sauce To this Low Carb Chicken Broccoli Casserole?

Yes! I have heard many people say that their ultimate comfort food includes a rich and creamy sauce, so there is a very easy variation that you can make here. 

The first time you make this low-carb casserole, I highly recommend trying it the way it’s written. The next time, you can add some chopped cream cheese, a can of cream of mushroom soup, or a can of cream of chicken soup right on top of the chicken, under the cheese. 

This will leave you with a very similar cheesy chicken broccoli rice casserole, but you’ll have a layer of creaminess that has baked down into the other ingredients as well.
