Essential Equipment for Making Keto BBQ Chicken Casserole
You don’t need a whole kitchen arsenal for this one, thankfully! Just a couple of basics will get you there:
- A Baking Dish: My go-to is usually a 9×13 inch dish, but honestly, any oven-safe casserole dish around that size will work like a charm.
- A Large Bowl: You’ll need something big enough to toss all those yummy ingredients around without making a huge mess.

Step-by-Step Guide to Your Keto BBQ Chicken Casserole
Okay, let’s get this amazing casserole into the oven! It’s honestly so straightforward, you’ll wonder why you haven’t made it a million times already. Just follow these simple steps and get ready for a flavor explosion!
Preheating and Preparing the Dish
First things first, crank up that oven! You’ll want to preheat it to 375°F (that’s 190°C for those of you who speak Celsius). While the oven’s getting nice and hot, give your baking dish a quick little grease. A swipe of butter or some non-stick spray works perfectly. This just makes sure nothing sticks and makes cleanup a breeze!
Combining the Keto BBQ Chicken Casserole Ingredients
Now for the fun part – mixing everything together! Grab your biggest bowl. Toss in that fluffy shredded chicken, the sugar-free BBQ sauce, the shredded cheddar cheese, and that dollop of sour cream. Now, get in there with a spoon (or maybe even your clean hands, I won’t judge!) and mix it all up until every single piece of chicken is coated in that yummy BBQ goodness. You want it all to look nice and combined.
Baking Your Delicious Keto BBQ Chicken Casserole
Once it’s all mixed, spread that glorious chicken mixture evenly into your prepared baking dish. Pop it into the preheated oven and let it bake for about 25 to 30 minutes. You’ll know it’s ready when the edges are all bubbly and it’s heated all the way through. I usually give it a little peek around the 25-minute mark just to be sure!
Garnishing and Serving
The final touch! Once it’s out of the oven, sprinkle those fresh, chopped chives all over the top. They add such a pretty pop of color and a fresh little zing. Serve it up hot and creamy, maybe with a side salad or some cauliflower rice. Make sure to check out these BBQ Chicken Zucchini Boats if you need more BBQ inspiration!

Tips for the Best Keto BBQ Chicken Casserole
Okay, so making this Keto BBQ Chicken Casserole is already super easy, but let me give you a few little tricks I’ve picked up to make it *extra* amazing. First off, the chicken! Using pre-cooked rotisserie chicken is a total game-changer for speed, but if you’re boiling your own, make sure it’s nicely shredded, not in big chunks. Also, don’t skimp on the sugar-free BBQ sauce – find one you really love because it’s the star flavor here!
And here’s a little something for you: if you love that BBQ chicken flavor but want something a bit different, you could totally try my BBQ Chicken Pasta Salad too. Back to the casserole, for even more gooeyness, feel free to add a bit more cheese on top before it bakes!
Ingredient Notes and Substitutions for Keto BBQ Chicken Casserole
Let’s chat about a couple of the key players in our Keto BBQ Chicken Casserole. First up, the sugar-free BBQ sauce. This is super important since regular BBQ sauce is usually loaded with sugar. There are tons of great brands out there now – G Hughes, Stubb’s, and Sweet Baby Ray’s all have sugar-free options that work wonderfully. Just grab whichever one you like best! If you’re feeling adventurous, you can even make your own.
As for the cheese, while cheddar is my go-to because it melts so nicely and has that classic flavor, feel free to mix it up! Monterey Jack, Colby, or even a little bit of pepper jack for a kick would be delicious. And you know, if you don’t have fresh chives on hand, a sprinkle of dried chives or even some finely chopped green onions works in a pinch for that fresh garnish!
