Baked Chicken and Cauliflower Casserole that is so cheesy and creamy! Cauliflower is roasted, added to a baking dish with bite size pieces of chicken breast, and then covered in a simple sour cream cheese sauce. Bake until bubbly!
Cheesy Chicken and Cauliflower Casserole
We love this cheesy cauliflower casserole so I hope you do too! It’s simple to throw together, filled with yummy cauliflower and juicy chicken, and oh yeah, that cheese sauce! Well you might need to lick the spoon when it’s done.
It’s hearty enough as a main course (we usually serve with dinner rolls or dill bread to dip in the sour cream cheese sauce), but you can absolutely serve as a side dish if you’d like too. However you serve it, just try it soon!

Fresh Cauliflower is best! But…
I love plucking fresh cauliflower from our little garden for this casserole, but frozen florets will do just as well when the harvest is quiet. No cauliflower on hand? Broccoli’s the perfect stand-in when you need it.

Line a baking sheet with parchment paper and add cauliflower on it, pouring olive oil and salt and pepper on top.

Add cooked chicken into a 9×9 (or 11×8) baking dish.
Add roasted cauliflower into the baking dish with the chicken.
In a large saucepan start making the creamy cheese sauce by melting butter with garlic. Add in flour, mixing until smooth and then add in chicken broth, stirring until bubbly.

Very yummy . I didn’t have fresh so I used frozen 16 ounces of cauliflower. I also added some pasta ( before cooking it was a cup. I seasoned my chicken and cauliflower. Stopped the casserole with some leftover chip crumbs so good.
