Tex-Mex Chicken Casserole is a fast, flavorful weeknight dinner that comes together in one bowl and finishes in under an hour. Use rotisserie or leftover cooked chicken and common pantry items—rice, black beans, corn, salsa, and a touch of sour cream—to create a creamy, satisfying casserole. Finish with plenty of melted cheese for the classic gooey topping.
This recipe is built for convenience and flavor: everything is mixed in a single bowl, transferred to an 8 x 8-inch baking dish, and baked until hot and bubbly. The one-bowl approach saves time and dramatically reduces cleanup, which makes this an ideal easy dinner for busy families, meal prep, or potlucks.
Leftovers are a bonus—stored in the refrigerator they develop even deeper flavor, and the casserole reheats well for lunches and next-day dinners. It also freezes nicely if you want to portion and save a meal for later.
Making Tex-Mex Chicken Casserole
To assemble, start by combining the creamy and spicy components in a large mixing bowl: sour cream, chunky salsa, canned green chiles, and a simple spice blend of cumin, garlic powder, and onion powder. This mixture creates a flavorful sauce that coats the other ingredients.
Stir in cooked, roughly chopped chicken, cooked rice, drained black beans, and sweet corn. Fold in half of the shredded cheese so it melts into the filling as the casserole bakes. Transfer the mixture to an 8 x 8-inch baking dish, sprinkle the remaining cheese over the top, and cover with foil to keep the casserole moist while heating through.
Bake in a preheated 350°F oven. Remove the foil near the end of baking so the cheese can finish melting and develop a light golden color. Freshly shredded cheese melts a bit more smoothly than pre-shredded varieties because it lacks the anti-clumping additives used in packaged blends, but both options work—use whichever is most convenient for you.
Bake uncovered for the final minutes just until the cheese is melted and the top looks inviting. Let the casserole rest briefly before serving so it sets slightly and is easier to portion.
Serving Tex-Mex Chicken Casserole
This casserole is versatile when it comes to toppings. Offer chopped green onions, diced tomatoes, sliced avocado, fresh cilantro, dollops of sour cream, or a spoonful of guacamole. Pico de gallo or an extra spoonful of salsa also brighten the dish and add freshness. Serve with a simple side salad, tortilla chips, or warm tortillas to round out the meal.
Because it reheats and freezes well, this Tex-Mex chicken bake is excellent for making ahead. Portion into airtight containers for quick lunches or freeze individual servings for convenient dinners later in the month.
The combination of shredded chicken, rice, black beans, corn, and a creamy salsa-sour cream base makes this dish filling and family-friendly—perfect when you want a savory, cheesy main course without a lot of fuss.
Ingredients
- 1/2 cup sour cream
- 3/4 cup chunky salsa
- 4 1/2 oz. canned green chiles, chopped
- 2 tsp ground cumin
- 1 tsp garlic powder
- 1 tsp onion powder
- 2 cups cooked chicken, roughly chopped (rotisserie or leftovers work well)
- 2 cups cooked rice

- 15 oz. sweet corn (or 1 1/2 cups frozen corn, thawed)
- 2 cups shredded Mexican blend cheese, divided
Instructions
- Preheat the oven to 350°F.
- In a large bowl, combine sour cream, salsa, chopped green chiles, cumin, garlic powder, and onion powder until well mixed.
- Add the cooked chicken, cooked rice, drained black beans, corn, and half of the shredded cheese. Stir until everything is evenly coated with the sauce.
- Pour the mixture into an 8 x 8-inch baking dish. Sprinkle the remaining cheese over the top and cover the dish with foil.

Notes
Optional toppings: chopped green onions, diced tomato, sliced avocado, chopped cilantro, extra salsa, guacamole, or a dollop of sour cream. Freshly shredded cheese will melt more smoothly than pre-shredded, but pre-shredded cheese is a convenient time-saver.
