I am such a huge fan of creamy casseroles. Easy, filling, and budget friendly, casseroles are a great family friendly option on busy weekdays. My issue with most creamy casseroles, is that they are either made with creamed canned soup (meh)  or are packed full of butter, cream, and cheese. I’m all about splurging but I’d rather splurge on Cheesecake Bars, not chicken casserole, ESPECIALLY when there is an incredibly simple alternative.

Cauliflower. Yep, steamed and puréed cauliflower, along with reduced fat cream cheese and 2% milk will give you the CREAMIEST and HEALTHIEST base for all your casserole needs. I kept this dish very simple and basic. Garlic, parsley, salt and pepper are my only seasonings. I love the flavor of the cauliflower sauce as it smothers the chicken and broccoli along with Barilla’s Protein Pasta*

I topped it all off with cheddar and breadcrumbs because really, Isn’t everything better with a cheesy crunchy layer 😋 My two youngest LOVED it, the five year old even asked and devoured seconds…. my oldest tolerated it but I figure 2 out of 3 isn’t bad. Ha ha ha. If you feel like it needs a bit more pizazz, you could always sauté some red bell pepper along with the onion, throw in some bacon bits, add crushed red pepper or add more cheese. Really, your options are endless. Let me know, what were your favorite add ins?
