Today I am doing something different that you may not have seen around here at Hello Spoonful before! I am making a chicken casserole that is literally a one pan meal that is ready in just 30 minutes! 

It’s full of mushrooms and broccoli, packed with protein from the chicken, and uses cauliflower rice for a lower carb, keto option!

A typical casserole is often filled with processed ingredients or full of grains and gluten. So I am really switching it up by using whole ingredients that are keto friendly, gluten free, budget friendly, and you won’t be dreading the cleanup after you make this healthy easy meal! 

Casseroles are really a foundation to comfort food, but not all comfort food has to be unhealthy! Once you try a scoop of this, you’ll easily want to make it once a week! 

Not to mention with the holidays coming up, you could totally swap out the chicken and use leftover turkey from your holiday meals!

Ingredients for Keto Chicken Casserole 

Chicken – you can use boneless skinless thighs or breasts. Before adding them to the casserole just cook and shred first!

frozen cauliflower rice

sliced mushrooms – if you don’t have fresh you can use canned and any variety is acceptable!

frozen broccoli cuts 

egg whites 

shredded mozzarella cheese 

parmesan 

garlic powder 

onion powder 

butter

Italian seasoning 

coarse sea salt 

How to Make Keto Chicken Casserole 

Spray a baking dish with non-stick cooking spray. You will want to use one larger in size, at least a 9×13. Then preheat your oven to 400 degrees. 

As I mentioned before we are going to be using cooked chicken, so you can go ahead and do that or use shredded rotisserie chicken.

Prepare the cauliflower rice and broccoli in the microwave according to the instructions on the package. You will probably have to do this in batches. 

Once it’s ready, add it to a large mixing bowl, followed by the egg whites, mushrooms, part of the mozzarella and parmesan, the spices, butter, and salt. Stir together until it’s mixed well. 

Add the cooked chicken to the bottom of the casserole dish, making sure the bottom is covered and it’s an even layer.

Sprinkle the remaining cheeses on top.

Cover and bake for about 25 minutes. Then remove the aluminum foil and continue baking for an additional 20 minutes or just until the cheese has melted on top. 

Let it cool just a bit then it’s time to serve!

Is this Casserole Good for Meal Prepping? 

Yes! This recipe makes 8 hefty servings, so if you have leftovers by all means take them for lunch for at least the next three days!
