Who knew exchanging riced cauliflower for rice would be so delicious?! My daughter served a similar chicken and broccoli casserole for dinner last year and it totally floored me that it was cauliflower!

Of course, since then I’ve made any number of dishes where I’ve used cauliflower to lower the carb content and still put out a pretty awesome meal. Recipes like Instant Pot Honey Garlic Pork Tenderloin served over riced cauliflower, Dump and Bake Pork Chop Casserole loaded with cauliflower tots, and now this easy keto Chicken Broccoli Casserole. It’s loaded with bacon, Gouda cheese, and garlic to pack in plenty of flavor. And it’s healthy and filling too!

It’s super simple to make and just the type of dinner I like to put on the table when the weather turns cold. You can use rotisserie chicken as shown in the recipe or, if you just happen to have some leftover turkey hanging around in your refrigerator, that will work too.

Recipe Variations

  • In lieu of rotisserie chicken, leftover chicken or shredded chicken can be used.
  • Change out the chicken for turkey, which is a great way to use up holiday turkey.
  • Not into Gouda cheese? Try cheddar or gruyere instead.
  • Bulk it up with even more veggies by adding mushrooms and, if you’re forgoing meat, you can even leave out the chicken!

This easy keto chicken broccoli casserole recipe has just eight ingredients, including a store-bought rotisserie chicken and two frozen packaged vegetables. It can’t get much easier than that! You can even make it ahead of time and store it in the refrigerator until ready to bake, just bring the casserole to room temperature prior to baking. Believe me, you’ll love this thick, creamy comfort food minus all the carbs!
