Casserole dish + cheese + sweatpants + glass of wine in hand = my kind of Friday night.

One of my favorite meals to make (especially once the cold weather starts to get stubborn) is a nice warm, bubbling with cheese, creamy casserole dish.

Cauliflower rice casseroles have become my new go-to dinner recipe because they have that nice balance of low carb/comfort food that’s so hard to find, and they’re quick and easy, making them the perfect week night dinner for my lazy winter self.

Anything that has the description “bubbling with melted cheese” has my full undivided attention ;).

This cheesy cauliflower casserole recipe uses two kinds of cheese:

Brie cheese-it’s one of those cheeses that melts velvety smooth. It has a nice mild flavor too and is lower in fat than typical cheeses. If you need to substitute the Brie cheese, I would use anything mild such as fresh mozzarella or even Swiss cheese.
Italian blend shredded cheese-typically a mix of mozzarella, Asiago, and parmesan cheeses which add a nice salty/sharpness that the casserole dish needs. If you can’t find the Italian blend, look for shredded Asiago or Parmesan cheese.

No boring casseroles going on in this kitchen!

Cheesy Balsamic Chicken Cauliflower Rice Casserole starts with mushrooms and chicken that is cooked in a creamy balsamic sauce. The cauliflower rice and peas are stirred in along with brie cheese and shredded Italian blend cheese and baked in the oven until the cheeses are golden brown and bubbling with cheesy creamy goodness.

These days, you can find cauliflower rice readily available at most grocery stores. Or, you can simply make your own but pulsing cauliflower florets in your food processor until it resembles the rice texture. I usually prefer to make my own because it’s much cheaper and I can freeze any rice that I don’t use until needed.

I love having a stash of cauliflower rice in my freezer because there’s so many healthy, low carb and easy cauliflower rice recipes you can make:

If you want to make a vegetarian version of this recipe, simply omit the chicken and add more mushrooms, or vegetables (I bet broccoli would be delicious!)

This casserole recipe can also be made ahead and placed unbaked in the freezer until ready to bake, making it an easy make-ahead dinner recipe. It’s all cooked in one pan and then transferred to a casserole dish for easy clean up!

Creamy Balsamic Chicken Cauliflower Rice Casserole is a one dish dinner that’s quick and easy to make so you can have more time for watching elephant documentaries on Netflix. Wait, what??? I do no such thing ;).
