BBQ Keto Chicken Casserole Recipe


Years ago, we used to order a meal at Chili’s Restaurant that included a chicken breast smothered in bbq sauce, bacon, and cheese. Since we’ve started following a keto/low carb lifestyle, I thought it would make a fabulous dinner. So, last weekend when my in-laws were in town, we went to Chili’s for dinner. I was so excited to order this again, but to my dismay, it’s no longer offered on the menu. Looking back, it is probably a good thing since regular BBQ sauce is so high in carbs. 

Instead, our waitress was happy to oblige and asked the kitchen to make me something similar without BBQ sauce. Although it was yummy, BBQ sauce would have made it amazing. Since then, I have worked on a new recipe for a low carb BBQ Sauce using my family’s original recipe that I tweaked. It made such a huge difference. 

This BBQ Keto Chicken Casserole with Bacon & Cheese turned out incredibly delicious, and it was so easy to make! My entire family loved it. You can find the recipe for my homemade low carb BBQ sauce here.


  • Boneless, skinless, chicken breast – I prefer to use chicken breasts, but you could substitute chicken thighs instead. 
  • Sugar-Free BBQ Sauce – You can buy sugar-free BBQ sauce at the grocery store, but remember to check the ingredients for hidden sugars. Or, better yet, make your low-carb BBQ sauce from my recipe using the link below.
  • Monterey Jack And Sharp Cheddar Cheeses – These cheeses will need to be grated. If you want to save a few minutes off prep time, feel free to purchase pre-grated cheese. Keep in mind that pre-grated contains added fillers that can increase the carb count. 
  • Bacon – Use cured or uncured, but make sure there are no added sugars whichever brand of bacon you choose. You might see sugar as an ingredient, but it is generally used in the curing process. The key is looking for 0 carbs in the nutritional info. 
  • Spices – The BBQ sauce will provide quite a bit of flavor to this tasty dish, but you will want to add garlic seasoning, salt and pepper for your preferences, and a teaspoon of parsley.

Step-by-Step Instructions for Making Keto BBQ Chicken

Step 1: Cook the boneless chicken breasts in a slow cooker for either six hours on the low setting or three hours on high. If you prefer, you can cook it in the instant pot for an hour. I like to add garlic, pepper, and salt with a little chicken broth. But you can season it however you prefer. Make sure to check out this post on how to make shredded chicken in the crockpot. 

Step 2: Preheat the oven to 350 degrees and prepare an 8×8 baking dish by greasing it. Then take the chicken out of the slow cooker or instant pot and chop it up. Try to cut it into large pieces.

Step 3: Place the chicken pieces in the bottom of the greased casserole dish and sprinkle garlic seasoning on top.

Step 4: Then, pour your choice of low carb BBQ sauce on top of it. I prefer my homemade recipe, but you can find sugar free bbq sauce options at the grocery store.

Step 4: Crumble the cooked bacon on top of the BBQ sauce. Then, cover it with the cheeses. Feel free to sub out different kinds of cheese such as Pepper Jack, mozzarella, white cheddar, etc.

Step 5: Bake the casserole in the 350-degree oven for 15 to 20 minutes, or until the cheese has completely melted. If you like to brown the cheese, place it on the top rack for two minutes.

Does it matter what kind of chicken is used?

For keto BBQ chicken, it won’t matter too much which type of chicken you use. Breasts are the most common and easiest to use, but other cuts will work just as well if you prefer them. Chicken thighs will add fat to the recipe since breasts are a leaner cut. When they are cooked in the slow cooker or the instant pot, the chicken will become tender, and you will cut it up into large pieces to make the casserole.

Ways to Enjoy the Best BBQ Chicken Casserole

I roasted asparagus in the oven to go with our Keto BBQ Chicken Casserole, and it was such a delicious meal. It’s relatively easy to make and complementary of many of your favorite Keto sides. But it is also good as a stand-alone dish, especially if you need something to take to a potluck or bring-your-own-dish event. You can bake it ahead of time and know you have at least one great-tasting keto-friendly dish. Southern Green Beans is a nice side, or you could pair the Keto BBQ chicken casserole with other Keto-friendly vegetable side dishes such as air fryer broccoli. You may also serve this alongside my easy keto coleslaw!

Can this be made ahead of time?

Sure, preassemble the casserole ahead of time and place it in the fridge. When you are ready to bake it, take it out of the fridge at least 30 minutes before baking to give it time to come to room temperature. Your baking time might be slightly increased since it has been refrigerated.

    1. Thanks! Great side options include a big salad, roasted asparagus, broccoli, green beans, etc.

  1. Hello! I’d like to make this tonight using the instant pot and chicken thighs instead of chicken breasts. Could you tell me what I need to change in terms of time/temperature? (I’m new to instant pot).

    1. You would need to enter the ingredients you used into some kind of tracking app to get the exact macros.

  2. Thank you for this recipe! It looks delicious! I am actually cooking it right now. I put the chicken in the crock pot, while cooking brunch.

    I used boneless skinless chicken breast, but instead of cutting the chicken after it was cooked. I did it before putting it in the crock pot, to cut down on the cooking time, and to avoid burning myself while trying to cut it later- I’m a little clumsy at times Lol. I am also thinking about adding broccoli and mushrooms to it, as well. But, I am now following you on Pinterest, and checking other recipes! Thanks again!!

  3. I made this for the first time tonight. So SO delicious!!! I tried your homemade BBQ sauce and I’m absolutely in love with the taste. Mine came out kind of runny. Not sure if I did something wrong or if you might have a suggestion to thicken it up while keeping it Keto friendly? Thanks for your advice and sharing your delicious recipes!

  4. I’m wanting to cook this in the Instant Pot tonight. Do you know what settings or temperature I should use?

    1. Hey, Crystal, I haven’t cooked this in the instant pot so not sure. Let me know how it turns out though!!

  5. I made this tonight and it is DELICIOUS!!! My husband and kids loved it, went back for seconds, and already asking me to make it again. I did add chopped red onion and baked the chicken (2 lbs). Great recipe, thanks for sharing! Will definitely make again!

  6. We made this regular Monterey Chicken recipe a few months ago and it turned out deliciously! I cooked the chicken in a skillet, which was a little time consuming, and when I stumbled upon this crockpot version, I knew I had to try it! I’m so excited to try cooking it this way and i’m sure its amazing as the other recipe!

    1. That is totally up to you. Feel free to sub out different kinds of cheese and you can cook the chicken in a skillet.

  7. 5 stars
    Making this casserole for the 2nd time because everyone liked it so much. Make sure you use Kasey’s BBQ Sauce because that Sauce is what makes this taste so so good! The flavors of the bacon, sauce & cheese is absolutey amazing!
