How to Make Mexican Chicken and Rice Casserole

Preheat the Oven

Preheat your oven to 400°F (200°C) so it’s ready for baking.

Warm the Broth

Heat the chicken broth in the microwave for about 2 minutes until hot. This helps the rice cook evenly in the oven.

Mix Everything Together

In a 9×13-inch casserole dish, combine the chicken, uncooked rice, onion, bell pepper, garlic, taco seasoning, black beans, Rotel, salsa, and warm chicken broth. Mix everything well so the flavors are evenly distributed.

Cover the dish tightly with foil to lock in moisture while baking.

Bake the Casserole

Bake for 35 minutes, then carefully remove from the oven and stir everything to ensure even cooking.

Add Cheese & Finish Baking

Sprinkle shredded cheddar cheese over the top. Return to the oven uncovered and bake for another 15 minutes, or until the cheese is melted, bubbly, and slightly golden.

Serve & Enjoy

Let the casserole rest for a few minutes before serving. Top with fresh cilantro and pico de gallo for a bright, fresh finish.

Tips for Success

• Cut chicken into even pieces for consistent cooking
• Make sure the dish is tightly covered for the first bake
• Stir halfway through to prevent uneven rice texture
• Add a splash of broth if the casserole looks dry
• Let it rest before serving so it sets properly

FAQs
