What Kind of Chicken Should I Use?

Shredded rotisserie chicken is a lifesaver in this recipe, but you can also use any cooked chicken breast or thighs you have on hand. Grilled, baked, poached—as long as it’s cooked through and shredded, it’s fair game. For extra flavor, try seasoning your chicken with a bit of cumin, garlic powder, and chili powder before adding it to the mix.

How To Make the Cheesy Chicken & Mexican Rice Casserole

Step 1: Preheat & Prep

Preheat your oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish.

Step 2: Mix the Filling

In a large bowl, combine cooked rice, shredded chicken, black beans, corn, diced tomatoes with green chilies, sour cream, 1 cup of shredded cheese, taco seasoning, and chicken broth. Stir everything together until evenly mixed.

Step 3: Assemble the Casserole

Pour the mixture into your prepared baking dish and spread it out evenly. Sprinkle the remaining 1 cup of cheese over the top.

Step 4: Bake to Perfection

Bake uncovered for 25–30 minutes, or until the cheese is melted and bubbly. If you like a little golden crust on top, broil for an additional 2-3 minutes at the end.

Step 5: Add Toppings & Serve

Once out of the oven, let the casserole cool for a few minutes. Then top with avocado slices, fresh chopped tomatoes or pico, a dollop of sour cream, and a sprinkle of cilantro. Serve with lime wedges for that fresh zing!

How to Serve and Store Cheesy Chicken & Mexican Rice Casserole

Frequently Asked Questions

Can I use brown rice instead of white?

Absolutely! Brown rice works well here—just be sure it’s fully cooked before mixing it into the casserole.

What can I substitute for sour cream?

Plain Greek yogurt is a great alternative to sour cream and adds a similar creamy tang.

Is this casserole spicy?

It has a mild kick from the taco seasoning and tomatoes with green chilies. For more spice, add jalapeños or a dash of hot sauce. For less, use plain diced tomatoes instead.

Can I make this ahead of time?

Yes! Assemble everything in the dish, cover, and refrigerate for up to 24 hours before baking. Add a few extra minutes to the baking time if cooking straight from the fridge.

Try avocado, fresh tomato or pico, extra cheese, chopped cilantro, jalapeños, or even a drizzle of ranch dressing.

Can I double this recipe?

Definitely. Use a larger baking dish or two smaller ones, and bake as directed. Perfect for feeding a crowd!
