Low Carb Chicken Casserole

Y’all, I can’t even tell you just how amazingly delicious this cheesy Low Carb Chicken Casserole is. I made it yesterday afternoon after a recommendation from Abbie in our Keto/Low Carb Challenge Facebook group (join here if you haven’t already). She had a brilliant idea to add chicken, broccoli, and mushrooms (I left out the mushrooms because I didn’t have any and we don’t like them anyway) to a casserole dish, then to pour the cheese sauce from my Cauliflower Mac N Cheese over the top and bake. She posted a picture of her casserole, and I knew this was a recipe that so many would enjoy as well.

I got in the kitchen and started experimenting with this super easy recipe and tweaked the original cheese sauce recipe just a bit. Holy cow! When the cheese sauce bakes into the chicken and broccoli, it tastes SO GOOD!!!

I cooked my chicken in my slow cooker as it always makes it so tender and flavorful, but you can also use a rotisserie chicken to save time. In the morning, I add boneless skinless chicken breasts to the slow cooker and cover them with a little broth, salt, and pepper. Then I cook it on high for either 3 hours on high for 3 hours. After it’s done, I use two forks to shred the chicken. Then, I begin layering the low-carb chicken casserole in a baking dish.

Quick Tip: Either fresh broccoli or steam bags of broccoli work great.

I used several different shredded kinds of cheese like cheddar cheese, mozzarella cheese, and parmesan cheese that I had grated. Feel free to swap out for Colby, Monterrey Jack, Gouda, or another variety of cheese if desired.

Doesn’t that cheese sauce look divine? Made with cream cheese, it’s extra smooth and delicious.

  • Preheat oven to 375 degrees. Cook chicken breasts in a slow cooker 3 hours on high or 6 hours on low. I always add a little chicken broth and salt and pepper, but you can use water instead. Remove from the slow cooker and shred. My family prefers chicken breasts, but you can use thighs or a whole chicken too. Or, skip preparing the chicken and use a rotisserie chicken instead to save time. 
  • Cook the fresh broccoli or microwave the steam bags of broccoli and drain.
  • In a saucepan, add butter, heavy whipping cream, garlic, and 1/2 of the Italian seasoning. Add softened cream cheese and stir with a whisk until thoroughly combined and cook over low medium heat until the sauce is smooth. 
  • Add cheeses stirring continually reserving 1/4 cup of cheddar cheese 1/8 cup of the other cheeses for the topping. 
  • Grease a 9 X 13 casserole dish and layer the shredded chicken first. 
  • Add the steamed broccoli on top of the chicken. 
  • Remove saucepan with the cheese sauce from the stove and pour on top of the broccoli and shredded chicken making sure that it is completely covered. 
  • Sprinkle the reserved cheese on top of the casserole along with parsley, paprika, and the remaining Italian seasoning. 
  • Bake in a 375-degree oven for 30 minutes. 
  • Enjoy!

    Dumb question but I’m counting daily calories…you have 409 calories for 12 servings. How many ounces in one serving? Thank you.

    1. I don’t weigh or measure my food. THe number of servings is listed at the top of the recipe card. Using that number I divide the recipe evenly.

    Let me tell you. My S.O. is newly keto (I am not. Nor my mother or child), so sometimes dinner can be a pain. Also I should note that my S.O. HATES veggies. I tried this about 2 weeks ago. THEY ATE ALLLLL OF IT and my 6 yo has asked for it every day since. I included some spinach in there as well with the broccoli. Top notch and will now be one of the number 1’s in rotation!

    1. WOW!!! That is amazing. I am so glad everyone enjoyed it so much! Thank you so much for sharing and taking the time to rate the recipe.

  3. This looks very similar to the Chicken Divan that I used to make many years ago…i like your cheese sauce better though. I used to substitute frozen (and thawed….though you could saute fresh spinach for this and use that instead too) Spinach instead of broccoli too for a Chicken Florentine (florentine meaning with spinach, anyway) type thing…….

    1. Hey, Cathy, I don’t usually plug in sodium levels on the recipe card. Most carb tracking apps will give that info to you if you input the ingredients. Hope this helps!

    Made this tonight and it’s delicious. Will be making this again for sure. Even my family loved it.
