Hi, my name is Jessica and I am addicted to “keto-izing” (keto-fying?) non-keto recipes. I should probably be embarrassed by how much enjoyment I get out of the process, but instead I just take photos and add the recipes to my blog for your enjoyment. 🙂

For this recipe, I modified a classic casserole recipe, often called “Chicken Ritz Casserole,” that uses (no surprise here) crushed Ritz crackers at the top and bottom of the casserole to add some crunch to a creamy, buttery filling. I subbed crushed pork rinds for the Ritz crackers, made a keto Condensed Cream of Chicken Soup (so easy to do!), and played around with the ingredients just a bit to come up with my own version.

Why You are Going to Absolutely Love This Keto Chicken Casserole

  • If you cook your chicken breasts ahead of time, you should be able to get this casserole on the table in less than an hour. Even if you don’t cook your chicken breasts ahead of time, you can shave some time off by cooking them while making the condensed chicken soup and gathering the rest of your ingredients.
  • It’s great as a main dish or side.
  • Even those who aren’t on keto will love it!
  • It tastes SO good. And I swear the leftovers are even better!

Ingredients Needed for Buttery Keto Chicken Casserole

There is only one “specialty” ingredient required for this casserole, and that’s the xanthan gum used to thicken the keto Condensed Cream of Chicken Soup. I tried to make the soup without it, but using more coconut flour made the soup too coconut-ty, and omitting it made the soup too thin. (Which, in turn, made the already creamy casserole a total mess.) Xanthan gum is a keto kitchen staple because it’s perfect for thickening soups, sauces, and drinks. One bag will last a long time, so it’s worth the (small) investment.

Additional ingredients:

  • Butter
  • Coconut flour
  • Chicken stock (I use Trader Joe’s Organic Chicken Stock because it has a great flavor and contains 0g carbs)
  • Almond milk
  • Pork rinds
  • Sour cream
  • Chicken breast
  • Bacon (pork or turkey)
  • Salt and pepper

Part 1: How to Make Keto Condensed Cream of Chicken Soup

It is “soup-er” easy (hah!).

Step #1: In a small saucepan over medium-low heat, melt butter.

Step #2: Add coconut flour and mix. Stir mixture quickly until it thickens.

Step #3: Add chicken stock and turn heat up to medium. Whisk to incorporate, then add almond milk and whisk. Finally, add xanthan gum and whisk.

Step #4: Turn up the heat slightly to bring the mixture to a low boil for 2 minutes.

Step #5: Remove from heat and add salt and pepper to taste. Let sit for at least 5 minutes before using it in your casserole (use this time to do other steps, like crush your pork rinds, dice chicken, etc).

FYI: You can make this condensed soup up to a day ahead of time and store it in the fridge. It will thicken more as it cools.

Part 2: How to Make Crusted Buttery Chicken Casserole

Step #1: Preheat oven to 325 F and grease an 8×8” casserole dish. (I used coconut oil.)

Step #2: Sprinkle half of the crushed pork rinds* on the bottom of the casserole dish, fully covering the bottom. Drizzle 3 tbsp of the melted butter on top. (*The easiest way to crush pork rinds is to stick them in a large Ziploc bag and crush them using a rolling pin.)

Step #3: In a medium-sized bowl, combine keto condensed soup, sour cream, chicken stock, diced cooked chicken breast, and diced cooked bacon. (You can use pork or turkey bacon. I used turkey bacon for these photos because it’s what I had on hand that day, but I’ve made it with pork bacon too. Both taste fantastic!)

Do NOT use raw chicken breast or bacon in this recipe! They MUST be cooked beforehand.

Step #4: Add the mixture to the casserole dish, evenly covering the pork rinds.

Step #6: Sprinkle the mixture in the casserole dish, evenly covering the top.

Step #7: Bake casserole for 30 to 35 minutes until the pork rinds have formed a nice crust.

How to Serve Keto Crusted Buttery Chicken Casserole

  • Serve as a main dish or side dish.
  • It pairs wonderfully with a side of low carb veggies.

How to Perfectly Measure Your Keto Chicken Casserole Macros

This is a moist casserole. Hot out of the oven, it’s a bit tricky to exactly measure servings. If keeping your macros absolutely spot-on is critical to you, here are my suggestions:

  • Chill the casserole before cutting into it, then cut each piece. Reheat before serving (or not… it tastes great cold, too!). I used a casserole dish with rounded corners for prettier photos, but a square dish will make this easier.
  • Weigh your casserole dish before cooking. After cooking (and cooling off the casserole!), weigh everything again. Subtract the weight of the casserole dish and divide by eight to get the precise weight of each serving.

The good news is this keto chicken casserole is extremely low in carbs (just a hair over 1g per serving), so a slightly mismeasured piece won’t wreak havoc on your carb intake.

    • Hi Beth! I haven’t personally tried it yet so I can’t vouch for the flavor, but you will need to replace the 1 tbsp coconut flour with 4 tbsp almond flour since coconut flour is extremely absorbent. If you give it a go, let me know how you like it!

  • I would say this is just good. I prefer eating great tasting food over food that will simply fill me. A couple of upgrades I can’t wait to try: bake the bottom layer of pork rinds before adding the filling, use salt and pepper in the pork rind topping, add broccoli, top with a sharp cheddar cheese.

    • Thank you for your feedback, Megan! Those sound like great modifications. I admit that I (and my taste testers) thought it tasted great (otherwise I never would have posted it!), but I know we all have different taste buds. Let me know how your modifications go!

  • Very good! Added a dash of Worcestershire sauce and minced garlic to the mixture and it was very similar to my go-to poppy seed chicken recipe (not low carb!). So this was the perfect substitute! Glad I came across this. Thanks!

  • Great recipe! Just curious, how do you get the video on top to minimize or go away? I really just want to see the full recipe at one time.

    • Hi E! I’m so sorry you’re having trouble. The video *should* be on the sidebar, but I’m having issues with it showing up on the top for some people like yourself. I’m working on a solution. Until then, the best place to view my site is on mobile (the video will go away as soon as you scroll past). I apologize for the inconvenience!

    • Hi Tamara! I haven’t tried it, but grated parmesan cheese may work. It will give it a different flavor and a bit of a different texture, but it would be worth trying… it’s hard to go wrong with cheese. 🙂

    • Hi Renee! You can do that. It will boost the carbs by about 22g for the entire dish (2.75g per serving), but since it’s already such a low-carb dish, it will still be keto-friendly. Enjoy!

  • I can’t wait to try this, this is one recipe I’ve missed being on Keto is Chicken Casserole!
    Thanks for working this up.

    • Hi Amber! You can, but there will likely be a bit of a texture change because of the dairy (which can get a little grainy when frozen and thawed). I wouldn’t freeze it longer than a month.

    • Hi Michelle! I haven’t tried it, but grated parmesan cheese may work. It will give it a different flavor and a bit of a different texture, but it would be worth trying.

  • I have made this recipe twice now; once the original way, which was tasty and liked by most of my family, but also with some modifications the second time. After making the condensed soup, I added 8 oz shredded sharp cheddar and melted it in the mix. I also steamed a bag of California blend veggies, added those to the chicken mixture, omitted the sour cream and bacon, then blended the soup/cheese mix with it. I must say I like the casserole better with the cheese and veggies. It boosts the flavor and the nutritional value. Thanks, Jessica, for a great basic recipe that is so conducive to personal additions!

    • Hi Rae Ann, Thank you so much for your review! Your additions and changes sound delicious. I’ve been working on some variations too and plan to update the post with those when they are complete. I agree that veggies and cheese are a tasty addition! 🙂

  • I’m fairly new to keto I ‘ve lost 34 lbs in 3 mo. I was looking for some ways to shake up my meals. After searching I luckily found your site and now I have awesome meals
    Thank you your amazing.
