If you have ever Googled "what to do with BBQ chicken" or "meals that use rotisserie chicken," this is your answer. One dish, minimal cleanup, and it feeds six people without breaking a sweat.
Casseroles sometimes get a bad reputation for being heavy or bland. Not this one. A few things make it stand out:
Chef's Tip: Day-old rice works even better than freshly cooked here. It absorbs the saucy filling without turning mushy during baking.
For a casserole like this, a good 9x13 baking dish makes all the difference between even cooking and hot spots. Using quality BBQ sauce, whether store-bought or homemade, is also where most of the flavor comes from, so choose one you genuinely like to eat.
Despite the name "casserole," this dish does not feel heavy or wintry at all. The corn and black beans give it a slightly Southwestern brightness, and the BBQ sauce keeps things lively. It is just as welcome at a summer cookout as it is on a cold Tuesday in February.
Think of it as a love letter to all those dinner BBQ ideas that look impressive but take almost no effort. Pulled chicken, a good sauce, cheese, and a hot oven. That is genuinely all this requires.
A note on the chicken: Any cooked, shredded chicken works here. Rotisserie is the fastest and most flavorful option. Leftover baked chicken thighs, grilled breast meat, or even canned chicken in a pinch all work well. This recipe was practically designed to make meals with rotisserie chicken fast and fuss-free.
Once you have made this once, you will see how easy it is to make it your own:
Ready to pull it all together? Here is the full step-by-step recipe:

This Easy BBQ Shredded Chicken Casserole transforms rotisserie or pulled chicken into a smoky, cheesy weeknight dinner the whole family will love. Ready in under an hour with simple pantry staples.
Preheat your oven to 375 degrees F (190 degrees C). Lightly grease a 9x13-inch baking dish with butter and set aside.
In a large mixing bowl, combine the shredded chicken, BBQ sauce, cream of chicken soup, sour cream, corn, black beans, green chiles, garlic powder, smoked paprika, and onion powder. Stir until everything is evenly coated.
Fold the cooked rice into the chicken mixture until fully incorporated.
Stir in 1 cup of the shredded cheddar cheese, reserving the remaining cheddar and all of the Monterey Jack for the topping.
Transfer the mixture into the prepared baking dish and spread it into an even layer.
Sprinkle the remaining cheddar and all of the Monterey Jack cheese evenly over the top of the casserole.
Bake uncovered for 30 to 35 minutes, until the cheese is melted, bubbly, and lightly golden at the edges.
Remove from the oven and let the casserole rest for 5 minutes before serving. Garnish with sliced green onions.
This casserole is a complete meal on its own, but it pairs beautifully with a crisp green salad, roasted broccoli, or warm cornbread on the side.
For leftovers, store the casserole covered in the fridge for up to 4 days. It reheats wonderfully in the microwave or oven, and the flavors actually deepen overnight, making next-day lunches something to look forward to.
If you want to get ahead, assemble the entire casserole the night before, cover it tightly, and refrigerate it unbaked. When dinner time comes, pull it straight from the fridge and add about 5 to 10 extra minutes to the bake time.
You can also freeze it before baking for up to 2 months. Thaw overnight in the refrigerator and bake as directed. It is one of those can chicken ideas that genuinely makes your future self grateful.
