Broccoli Cauliflower Rice Chicken Casserole

Recipe Description

This Broccoli Cauliflower Rice Chicken Casserole is a delicious healthy midweek dinner. This recipe ticks a lot of boxes for me – it is low in carb yet absolutely delicious and very filling. You’ll love it! 

To make this delicious casserole, start by baking chicken in the oven. Meanwhile, heat the frozen cauliflower rice and broccoli according to package instructions and discard any excess water or moisture. Once cooled slightly, carefully chop the chicken into bite-sized pieces. Place cooked cauliflower rice, broccoli, chicken, eggs, mozzarella cheese, salt, garlic powder, onion powder, and butter in a large bowl and mix together until fully combined.

Transfer the mixture to a baking dish and top with the remaining cheese. Bake in the oven until the cheese on top has fully melted and started to brown slightly. Cool slightly for 10 minutes before serving.

This casserole really blew my mind. I whipped it up for dinner and it turned out so nummy. I ain't a chef, but this dish made me look like one. My friends couldn't believe it was low carb. Perfect for my midweek meals, can't wait to make it again.
