I’ve made this casserole countless times for friends, family dinners, and even meal prep. It reheats beautifully and can easily be customized to suit whatever’s in your fridge.

Why You’ll Love This Creamy Mexican Rice & Chicken Dinner Casserole

It’s the ultimate one-dish wonder. This casserole combines creamy textures with zesty, savory flavors that hit the spot every time. It’s perfect for weeknights, freezer-friendly, and great for feeding a hungry family. Plus, the toppings like avocado, sour cream, and fresh cilantro let you customize it to your taste.

What Kind of Chicken Should I Use?

You can use rotisserie chicken, leftover grilled chicken, or even poached chicken breasts — whatever is most convenient. I personally like using rotisserie chicken for its tenderness and built-in flavor, which saves a step and adds depth to the dish.

Options for Substitutions

You’ve got flexibility with this casserole. Don’t have black beans? Pinto beans work great. No corn? Just skip it or use diced bell peppers instead. Not into spice? Use mild salsa or skip the jalapeños altogether. You can also swap white rice for brown rice or even quinoa if you’re aiming for a healthier version. And for a vegetarian option, just leave out the chicken and double up on beans and veggies.

Step 1: Preheat and Prepare the Dish

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with olive oil or nonstick spray. This prevents sticking and makes cleanup easier.

Step 2: Make the Creamy Base

In a large bowl, combine the softened cream cheese with your salsa. Stir until smooth and creamy. Then add the cumin, chili powder, garlic powder, onion powder, salt, and pepper. This mixture forms the creamy, flavorful base that holds the casserole together.

Step 3: Mix the Filling

Add the cooked rice, shredded chicken, black beans, corn, and half of the shredded cheese to the cream cheese mixture. Stir until everything is evenly coated and well combined.

Step 4: Assemble the Casserole

Spread the mixture into your prepared baking dish, smoothing it out with a spoon or spatula. Sprinkle the remaining shredded cheese evenly over the top.

Step 5: Bake Until Bubbly

Place the casserole in the oven and bake uncovered for 20-25 minutes, or until the cheese is melted, bubbly, and golden on top.

Step 6: Garnish and Serve

Remove from oven and let it cool for 5 minutes. Top with diced avocado, chopped tomatoes, sour cream, and fresh cilantro just before serving. This adds freshness and a cooling contrast to the rich and creamy base.

How Long to Prepare the Creamy Mexican Rice & Chicken Dinner Casserole

Prep Time: The preparation takes about 15 to 20 minutes. This includes shredding the chicken (or using rotisserie), cooking or reheating the rice, mixing the ingredients, and assembling everything into the baking dish.

Bake Time: Once the casserole is in the oven, it needs about 20–25 minutes to bake. During this time, the cheese melts into a bubbly, golden crust and the flavors meld together.

In total, you’re looking at around 40–45 minutes from start to finish, making it weeknight-friendly.

Tips for Perfect Creamy Mexican Rice & Chicken Dinner Casserole

• Use freshly cooked or reheated rice so it mixes well with the creamy base without clumping.
• Don’t skip the cream cheese step—mixing it with salsa beforehand ensures a smooth consistency throughout.
• Let it rest before serving. A 5-minute rest helps the casserole set and makes serving cleaner.
• Add toppings just before serving so the avocado stays fresh and vibrant.
• Taste the mixture before baking to adjust seasoning—especially salt and spice.

Watch Out for These Mistakes While Cooking

• Using cold cream cheese: This can make the mix clumpy. Soften it to room temp first.
• Overcooking the casserole: It can dry out if baked too long. Watch for that golden top as your cue.
• Adding wet ingredients like watery salsa or under-drained beans: It may make the casserole soggy.
• Not seasoning the rice beforehand: Bland rice can flatten the whole dish.
• Skipping the rest time: Cutting into it too soon can cause it to fall apart.
