Keto Chicken Broccoli Casserole Recipe

Casseroles are a comfort food. However, many of them are made with high carbohydrate ingredients and can spike your insulin and increase inflammation. It is always nice to find a recipe or dish that you can modify to taste fantastic. Chicken broccoli casserole was one of my favorites growing up. The croutons on top took it out of the gluten free and ketogenic category, so I left them out. This keto chicken broccoli casserole version is still simply delicious, even without the croutons. I have been seeing that people are using pork rinds to add a crispy crusty layer to the top. I’m going to try that next!


  • 2 cans cream of mushroom soup
  • 1 onion, diced
  • 1 cup of mayonaise
  • 1 large head of broccoli chopped
  • 1 pound of cooked chicken
  • 1 1/2 cups shredded cheddar cheese


Dice the cooked chicken. Chop the broccoli. Place a layer of broccoli in a 9×13 inch pan. Layer the cooked, diced chicken on top. Add the diced onion. Put the mayonnaise and cream of mushroom soup in and stir it around. Mix well with the goal to coat the broccoli and chicken. Sprinkle shredded cheddar cheese on top. Bake at 350 for 30 minutes covered with tin foil. Remove the tin foil and let cook for another 10 minutes to allow the cheese to get crisp. Remove from oven and let cool for ten minutes before serving. Enjoy!

For convenience, I used Campbell’s cream of mushroom soup. This does have some extra carbohydrates in it. A serving of the canned soup is 9 carbohydrates, which is a lot, but you are mixing it in with lower carbohydrate vegetables, chicken and mayonnaise, which helps to lower the carb count per serving. Just make sure that you aren’t eating mega-size portions and you should be able to enjoy it in your ketogenic diet meal plan.

You can make substitutions for the Campbell’s cream of mushroom soup. There are recipes that use sour cream or heavy cream. This is my mom’s recipe. I may tweak it a little more to make it even more low carbohydrate, but for now, I love it! Here’s a picture of the final keto chicken broccoli casserole.

You don’t have to use the same brands that I use, but I’m including links to Amazon of the products that I use in case you want to check out reviews or order them.
