Low Carb Chicken Alfredo Brussels Sprouts Casserole

I have been doing the Keto diet for some time, with several time saving spins I have just for myself.  For main dishes at home, we try to follow the Keto diet as much as possible just because we feel better and healthier without loading up on carbs every weeknight!   This Low Carb Chicken Alfredo Brussels Sprouts Casserole was something I threw together for an easy casserole idea- keeping with the Keto friendly ingredients.

Brussels Sprouts poured

If Brussels Sprouts aren't on your menu, don't be afraid to try it! They are a great vegetable option especially if you are keeping to a Keto diet and you are tired of cauliflower and broccoli! Add your Brussels Sprouts to your casserole dish to make up the first layer of this casserole.

Next you will add your prepared Chicken Breast Strips, roughly chopped into bite sized pieces.  I used the prepared bagged chicken, but if you are into food prep big time and have your own fresh cooked chicken breast chopped up and ready to go– use it! I have been known to prepare several skinless boneless chicken breasts ahead of time in my instant pot, and just chop them up and freeze for recipes like this.  Frugal and of course healthy!

Alfredo Sauce

Next you will mix up your homemade Alfredo sauce on the stove top.  If a homemade sauce sounds scary, it's really no big deal. Sauces are a great thing to learn how to cook at home, just to avoid all those preservatives, added sugar and salt we find in store-bought sauces.  For casseroles, you will lose a LOT of flavor using a store-bought Alfredo sauce, so definitely don't skip this step! I love this creamy cheese sauce.

My family started doing Keto in June of 2018. We chose to do Keto because my husband has Ankylosing Spondylitis and my son has horrible Psoriasis.
