Mexican Chicken Casserole Ingredients
For the Base
• Uncooked Rice – This provides the perfect structure and texture; brown rice can be a nutritious substitute, but remember, it requires longer cooking time.
• Minced Garlic – Adds that essential depth of flavor; fresh garlic enhances the dish beautifully, though garlic powder works in a pinch.
• Chopped Onion – Contributes sweetness and complexity; shallots or leeks can be lovely alternatives for more subtle flavors.
• Chicken Broth – Essential for cooking rice and adding moisture; feel free to opt for vegetable broth for a vegetarian version.
For the Filling
• Cubed Chicken Breasts – The hearty protein source in this dish; shredded rotisserie chicken can save time on busy nights.
• Black Beans (canned) – Integrates protein and creaminess; you can switch to pinto beans or chickpeas for a delightful change.
• Corn (frozen or canned) – Brings sweetness and a pop of color; any favorite veggie can brighten the dish too.
• Salsa – Imparts moisture and flavorful punch; if you prefer a chunkier texture, go for chunky salsa, or choose smooth for a saucier outcome.
For the Flavor Boost
• Chili Powder – Elevates the dish with just the right amount of spice; adjust according to your heat tolerance, or use paprika for a milder taste.
• Paprika – Adds a dash of color and mild smokiness; smoked paprika introduces an exciting flavor depth to the mix.
• Shredded Cheddar Cheese – Melty and delicious, this topping creates a delightful crust; feel free to swap in Monterey Jack or vegan cheese as desired.

Step‑by‑Step Instructions for Cheesy Mexican Chicken Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This allows the casserole to cook evenly and ensures that the cheese melts to perfection. As the oven warms up, gather your ingredients and a large 12×9-inch casserole dish to prepare your delicious Mexican Chicken Casserole.
Step 2: Mix the Base Ingredients
In your prepared casserole dish, combine the uncooked rice, minced garlic, chopped onion, and chicken broth. Stir well until all the ingredients are nicely mixed, making sure the rice is evenly distributed. This base will soak up the flavors as it bakes, transforming into a delightful bed for the casserole's layers.
Step 3: Layer the Filling
Now, it's time to layer the fillings! Gently place the cubed chicken breasts over the rice mixture, followed by the black beans, corn, and salsa. Make sure that the rice is mostly covered by these ingredients, as this ensures even cooking. Sprinkle the chili powder and paprika on top for an extra kick of flavor, enhancing your Mexican Chicken Casserole.
Step 4: Add Cheese
Sprinkle a generous layer of shredded cheddar cheese over the top of the casserole. The cheese will melt beautifully and form a golden, bubbly crust as it cooks. The melted cheese is essential for giving this dish its comforting and satisfying texture that complements the other tasty layers.
Step 5: Bake Covered
Cover your casserole dish tightly with aluminum foil and place it in the preheated oven. Bake for 45 minutes, allowing the rice to cook through and absorb all the delicious flavors. The foil traps steam, ensuring everything stays moist and tender while the cheese patiently awaits its golden moment.
Step 6: Uncover and Finish Baking
After 45 minutes, carefully remove the foil, being cautious of the hot steam. Continue to bake the casserole for another 10 minutes, or until the cheese is bubbly and golden brown. This step is crucial for achieving that irresistible cheese crust that will make your Mexican Chicken Casserole a family favorite.
Step 7: Check for Doneness
Once the timer goes off, check the rice for doneness. It should be tender and fully cooked. If necessary, stir the casserole gently and cover it again to bake for an additional few minutes. This guarantees everything is properly cooked through, especially the chicken, which should reach an internal temperature of 165°F (74°C) before serving.

Make Ahead Options
These Cheesy Mexican Chicken Casserole delights are perfect for meal prep enthusiasts! You can prepare the entire casserole up to 24 hours in advance by assembling all the layers in the dish, covering it tightly with plastic wrap and foil, and refrigerating. Make sure to keep the rice fully submerged in the broth for even cooking. When ready to bake, simply remove the covering and pop it in the preheated oven, adding an extra 10 minutes to the baking time, if coming straight from the fridge. For those aiming for longer storage, you can freeze the unbaked casserole for up to 2 months. Just remember to thaw it overnight in the fridge before baking; your family will enjoy a comforting, homemade meal with minimal effort!

If the rice is still crunchy after baking, don’t worry! Cover the casserole again and let it bake for another 5-10 minutes. Make sure to check periodically, and if necessary, add a splash of chicken broth to help steam the rice to perfection.
