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!

    I just found this last week & made twice, it’s already a family favorite! I have no idea how much of each ingredient I used as I just eyeballed it. This is absolutely one of the best casseroles I’ve ever made. Thank you for sharing!

  2. Making this tonight. It’s in the oven right now. Used rotisery chicken. It smells wonderful! It should be done in a couple of minutes. Can’t wait to try it.

    1. The number of servings is listed at the top of the recipe card. I divide it evenly by that number.

    1. 5 stars
      As usual with your recipes, this one was wonderful. I could easily eat way more than allowed! Thank you!

  3. In the oven now! I get confused because when I weigh ounces of cheese on my scale 8 oz does not fill just 1 measuring cup. I wish recipe would just say how many cups of cheese as opposed to ounces. When recipe says to reserve cheese to the side it says cups, so why not give entire recipe in cup portions? Just one thing that confuses me when I’m making a recipe. I ended up eyeballing the cheese and thinking 3 cups of cheddar and 1 cup of mozzarella looked good. Can’t wait to try it!

    1. You really can’t go wront with the cheese. I eyeball everything if I don’t have measurements.

    2. I really APPRECIATE having measures by weight rather than volume. Everyone will measure a cup of something differently based on how much they pack it down but 12 ounces is 12 ounces.
      (I also measure everything, in order to accurately calculate macros.)

      I made this tonight and my husband loved it. I’m new to your blog but I’ll be back.

    1. The info is listed in the post. It could change texture a bit due to the dairy products, but it would still taste the same.

  4. 5 stars
    I made this tonight and it was a hit! DELICIOUS! I will definitely be making this again. I also added roasted garlic and chopped up some red onion in the spinach. I do need to season the chicken a little more before baking, but it was really tasty.

    1. Hey Tina, you can add just the pork rinds for a crunchy topping or different spices with the pork rinds to kick it up a bit. It’s all about what you’re looking for in the crunchy topping. I hope you enjoy it!!

  5. 5 stars
    This is soooooo good!! We cheat sometimes and serve it over pasta, but that’s completely optional. It also keeps really well. Since the recipe makes a good bit, my mom (who lives alone) separates it into individual serving containers and refrigerates or freezes it. Thank you so much for the recipe!! I’m sharing it on my cooking Instagram!!

    1. The number of servings is listed at the top of the recipe card. I simply eyeball and divide into equal portions by the serving size number.

  6. 5 stars
    Fantastic. And I used half and half and fat free cream cheese. Couldn’t tell I was missing a thing, and probably cut 50-75 calories per serving.

  7. 5 stars
    This was absolutely perfect. I made it tonight and myself and the hubby loved it. He took one bite and immediately said, “This is a keeper.” Thank you!

    1. I’m sure it could. I’m not sure the exact bake time as I’ve only made it as is.
