I have never understood why casseroles get a bad rap. They are a super simple way to get all your macros in one fell swoop. Perhaps it is because they don’t exactly look very appealing, especially to a child when you’re first introduced. And let’s be honest, it leaves you wondering what mom is trying to hide in that mash up of ingredients?

But, for busy moms and dads, and even those who are just looking for a stress-free meal to prepare during the week (and less dirty dishes to clean up), casseroles are game changers.

A chicken and rice casserole is one of my typical “go-to’s.” And generally when I think of a chicken and rice casserole, it includes broccoli. I wanted to change this up a bit, as well as make it more keto friendly, so I came up with a recipe that I hope will make it to your weekly rotation. This chicken alfredo casserole earned two thumbs enthusiastically raised from my crew, so for me it’s a win-win.

Low-Carb Chicken Alfredo Casserole Recipe


  • 1 head cauliflower
  • ¼ cup extra virgin olive oil (EVOO)
  • 1 tsp dried basil
  • 2 ½ cups spinach
  • 2 cups rotisserie chicken
