Ingredients You’ll Need
You’ll need cooked and diced chicken, black beans, diced tomatoes, a small white onion, and a red bell pepper. Add taco seasoning for that signature flavor, along with shredded cheddar cheese, sour cream, and a squeeze of fresh lime juice. Top it all with chopped green onions before baking for a fresh, colorful finish. Optional toppings like avocado, jalapeños, sour cream, tortilla chips, or salsa make each serving unique. You can also use rotisserie chicken or a mix of cheese blends like Monterey Jack for an even creamier result.
How to Make Chicken Taco Casserole
Prep Your Ingredients
Preheat your oven to 350°F. Dice the onion and red bell pepper, then rinse the black beans until clean and ready to use.
Mix the Filling
In a large mixing bowl, combine the cooked chicken with sour cream, lime juice, diced tomatoes, and taco seasoning. Mix until smooth and creamy, then fold in half of the shredded cheese.
Assemble the Casserole
Lightly coat a baking dish with cooking spray. Add the black beans, diced onion, and bell pepper, then stir them together. Spread the chicken mixture evenly on top of the vegetables.
Bake and Serve
Sprinkle the remaining cheese and green onions evenly on top. Bake for about 30 minutes until the cheese is melted and bubbly. Let it rest briefly before serving. Add toppings like avocado, sour cream, jalapeños, or crushed tortilla chips for an extra layer of flavor and crunch.

Pro Tips for the Best Chicken Taco Casserole
Cut your chicken into even pieces for the best texture throughout. Try using different cheese blends such as cheddar and Monterey Jack for added creaminess. To increase the spice, add more taco seasoning or fresh jalapeños. Leftovers can be stored in the fridge and often taste even better as the flavors deepen overnight. For the best texture, reheat it in the oven so the cheese stays melty instead of rubbery.
Serving Ideas & Perfect Pairings
This casserole goes perfectly with fresh Pico de Gallo, warm flour tortillas, or flavorful sides like Dirty Rice, Bomba Rice, or a Frito Taco Salad. For drinks, try a chilled lime margarita or a tall glass of iced tea. It’s a complete, comforting meal that’s great for family dinners, potlucks, or even casual weekend gatherings.
