Ingredients You’ll Need

Each ingredient in this Mexican Chicken Casserole Recipe plays a key role—rice soaks up all those delicious flavors, while black beans and corn add texture and protein. When shopping, pick a good quality salsa and fresh chicken breasts for best results.

• Long grain white rice: Absorbs the chicken broth and salsa making the base tender and flavorful.
• Minced garlic: Gives a subtle aromatic punch that builds depth.
• Chopped onion: Adds a mild sweetness when cooked through the casserole.
• Chicken broth: Helps cook the rice while infusing the dish with savory goodness.
• Chicken breasts: I cut them into cubes to ensure even cooking and quick bake times.
• Black beans: Rinsed and drained to reduce sodium but keep that creamy texture.
• Frozen corn: Defrosted so it doesn’t add excess moisture but brings a touch of natural sweetness.
• Salsa: Choose your preferred heat level—mild to medium works great for most.
• Chili powder: Boosts the Mexican vibe with gentle smoky spice.
• Paprika: Adds color and sweetness without overpowering the dish.
• Cheddar cheese: Sharp cheddar melts beautifully, creating a golden, bubbly topping you won’t want to skip.

Variations

I love that this Mexican Chicken Casserole Recipe is a great base to customize. Over time, I’ve tweaked it to match different tastes and what’s in my fridge, and it’s always a hit.

• Add Fresh Jalapeños: For a spicier kick, I toss in sliced jalapeños before baking. It wakes up the dish in the best way.
• Use Brown Rice: I swapped white rice for brown once for a nuttier flavor and a bit more fiber—just remember to increase the cooking time accordingly.
• Vegetarian Version: Skip the chicken and double up on beans or add diced bell peppers for a meat-free twist that’s still satisfying.
• Cheese Swap: Sometimes I use pepper jack instead of cheddar for a little extra melty heat.

How to Make Mexican Chicken Casserole Recipe

Step 1: Layer the Ingredients Just Right

Start by preheating your oven to 350°F (175°C). In your casserole dish, spread the uncooked white rice evenly on the bottom. Then sprinkle minced garlic and chopped onion over the rice before pouring the chicken broth evenly on top. This layering is key because the rice needs to absorb the liquid and cook perfectly—keeping it on the bottom ensures that.

Step 2: Add the Protein and Veggies

Next, layer the cubed chicken breasts over the rice mixture. Scatter the black beans and defrosted corn evenly on top, then pour the jarred salsa across everything. Sprinkle chili powder and paprika to bring out those signature Mexican spices. Try to avoid mixing the rice here—your goal is to keep it layered so it cooks through properly without turning mushy.

Step 3: Cheese It Up and Bake

Finally, sprinkle the shredded cheddar cheese all over the top. Cover the casserole tightly with foil (don’t skip this part!) to trap steam and help the rice and chicken cook evenly. Bake covered for 45 minutes, then remove the foil and bake uncovered for another 10 minutes or until the cheese melts and starts to brown lightly. You’ll see it bubbling – that’s your cue it’s ready to come out!

How to Serve Mexican Chicken Casserole Recipe

Garnishes

I like to top my servings with a dollop of sour cream or creamy guacamole for richness, plus a handful of fresh cilantro leaves or chopped green onions for a bright pop. Sometimes a squeeze of lime juice really livens things up too – it cuts through the cheese beautifully.

Side Dishes

Rice and beans are already in the casserole, so I keep sides light—think a simple mixed green salad or a crisp slaw with lime dressing. Plus, warm tortillas or cornbread pair nicely if you want a more filling meal or some fun dipping options.

Creative Ways to Present

For dinner parties, I’ve served this casserole in individual ramekins and topped each with a playful garnish of sliced avocado and radish slices. It looks special and guests love feeling like they each get their own personalized portion.

Make Ahead and Storage

Storing Leftovers

I store leftovers in airtight containers in the fridge for up to 3 days. The casserole actually tastes even better the next day once the flavors fully meld. Just keep the cheese covered tightly so it doesn’t dry out.

Freezing

This Mexican Chicken Casserole Recipe freezes nicely—after cooling completely, portion it into freezer-safe containers or wrap the entire dish tightly with foil and plastic wrap. It keeps well for up to 3 months. When I freeze it, I usually undercook the rice slightly so it doesn’t become mushy on reheating.

Reheating

Reheat leftovers covered in the oven at 350°F until warmed through, about 20-25 minutes. You can also microwave single servings nicely if you cover them to keep moisture in. Adding a splash of chicken broth before reheating refreshes the rice beautifully.
