Top Tip💡
This low-carb recipe is the perfect way to use leftover chicken! Chicken breast or chicken thighs work great, and that way, you’re also cutting down on food waste. Cooked rotisserie chicken from the grocery store works well, too.
Substitutions
- Head of cauliflower – If you want to cut your own cauliflower, you can. I just use the frozen options that are already done and ready to save on time. If you want to make your own cauliflower rice, go for it! It’s a fun way to change the texture!
- Shredded cheese – Any type of cheese will work for this creamy chicken casserole so have fun with flavors. You can add lots of cheese, or a little – up to you.
Variations
- Spicy – Adding chili powder or cayenne pepper to this creamy cheese sauce can be a simple way to add a kick of heat.
- Buffalo – Add in some buffalo sauce to make a buffalo chicken cauliflower casserole!
- Chicken broth – To thin out the creamy sauce, a little bit of chicken broth can be used.
- Seasonings – Adding ranch seasoning to this dish is another fun flavor option!
- Cauliflower rice – You can make the cauliflower pieces into smaller sizes or rice by adding them to a food processor. I use it both ways for the texture.

Common Questions
You can. I use bigger pieces of cauliflower because I like the texture. And I just like to use the frozen kind as it cuts down on the prep time needed to make this dish.
But you can also use riced cauliflower, too! Options are good!
To stick to the ketogenic diet, pair this with a side salad or even a side dish of fresh fruit. Even though the casserole is low in carbs, it doesn’t mean that it’s not hearty! Having a light side dish or dessert to follow is a great way to round out the meal.
You can. Just be sure to let the chicken thaw completely, and then drain any excess liquid from it before using it. I always have frozen shredded chicken in my freezer for recipes just like this!
