This easy BBQ shredded chicken casserole is the ultimate weeknight comfort food, loaded with tender pulled chicken, smoky barbecue sauce, and melty cheese. Perfect for using up rotisserie chicken in under an hour!

Some recipes just have a way of showing up at exactly the right moment. This BBQ shredded chicken casserole is one of those dishes. It is hearty, smoky, cheesy, and deeply satisfying in a way that only a proper comfort food casserole can be. And the best part? It comes together in about 15 minutes of actual hands-on work.
Whether you are staring at a leftover rotisserie chicken in the fridge, looking for easy supper casseroles families actually devour, or just trying to figure out what to do with BBQ chicken from last night, this recipe is the answer. It is one of those meals that feels like way more effort than it actually is.
The secret here is layering flavors that already love each other. Smoky BBQ sauce wraps around tender pulled chicken, while cream of chicken soup and sour cream create a rich, creamy base that holds everything together beautifully. Black beans and corn add heartiness and a gentle sweetness, and that crunchy tortilla chip topping? Total game changer.
This is also one of the most flexible meals that use rotisserie chicken you will ever find. Grab a bird from your grocery store on the way home, shred it in about five minutes, and you are already halfway to dinner.
Chef's Tip: The crunchiest topping comes from adding your crushed tortilla chips right before the casserole goes into the oven. If you add them too early, they absorb moisture and go soft. Timing is everything.
For a casserole like this, the BBQ sauce you choose will define the entire flavor profile. A smoky, slightly sweet sauce works beautifully here, but a bold and tangy variety gives it more of a summer cookout feel. Both are delicious. Good quality shredded cheese, freshly grated if possible, also melts far better than the pre-shredded bags.
Having the right kitchen tools for easy assembly helps too, especially a large mixing bowl and a solid 9x13 baking dish that distributes heat evenly.
This is the kind of dinner BBQ ideas are made of, without needing to fire up a grill. It has all those warm, smoky, cookout flavors in a format that works year-round. Thinking about summer chicken casserole recipes that actually hold up in the heat? A dish that bakes quickly, serves a crowd easily, and does not require standing over a stove is exactly what you want.
It also makes an excellent dish for potlucks, meal prep Sundays, or those nights when everyone in the house is hungry at different times. It reheats like a dream.
Ready to dig in? Here is the full step-by-step recipe to make this crowd-pleasing BBQ shredded chicken casserole tonight:

This easy BBQ shredded chicken casserole is the ultimate weeknight comfort food, loaded with tender pulled chicken, smoky barbecue sauce, and melty cheese. Perfect for using up rotisserie chicken in under an hour!
Preheat your oven to 375 degrees F (190 degrees C). Lightly grease a 9x13-inch baking dish with cooking spray and set aside.
In a large mixing bowl, combine the shredded chicken, BBQ sauce, cream of chicken soup, and sour cream. Stir until everything is evenly coated.
Fold in the corn, black beans, diced green chiles, garlic powder, smoked paprika, onion powder, salt, and black pepper. Mix until well combined.
Stir in 1 cup of the shredded cheddar cheese and all of the Monterey Jack cheese into the chicken mixture.
Transfer the mixture into the prepared baking dish and spread it into an even layer.
Sprinkle the remaining 0.5 cup of cheddar cheese evenly over the top of the casserole.
Scatter the crushed tortilla chips over the cheese layer to create a crunchy topping.
Bake uncovered for 30 to 35 minutes, until the casserole is bubbling around the edges and the topping is golden and crisp.
Remove from the oven and let the casserole rest for 5 minutes before serving.
Garnish with fresh chopped cilantro and serve hot with extra BBQ sauce on the side if desired.
One of the biggest wins with this recipe is how well it stores. Leftovers taste just as good the next day, arguably better once all those flavors have had time to meld overnight.
Refrigerator: Store covered for up to 4 days. Reheat in the microwave or covered in the oven at 350 degrees F.
Freezer: Assemble without the chip topping and freeze tightly wrapped for up to 2 months. Thaw overnight in the fridge, top with fresh chips, and bake as directed.
Make-Ahead: Fully assemble the casserole without the chip topping, cover, and refrigerate up to 24 hours in advance. Add chips right before baking.
Storage Note: Keep leftovers in an airtight container rather than leaving them in the baking dish. It helps maintain the texture and keeps the casserole from picking up any fridge odors.
However you serve it, this easy dinner recipe with pulled chicken is the kind of meal that earns a permanent spot in your weeknight rotation. Simple ingredients, minimal prep, and a finished dish that looks and tastes like you really put in the effort. That is the kind of recipe everyone needs in their back pocket.
