Cheesy Chicken, Black Bean & Corn Mexican Rice Casserole
From the photo, this looks like a Tex-Mex chicken-and-rice casserole layered with chicken, rice, black beans, corn, melted cheese, avocado, salsa, and green onions. Since a photo can’t reveal exact quantities, the recipe below is a carefully reconstructed version rather than claiming to be the exact original recipe. Similar chicken-rice casseroles commonly combine chicken, rice, black beans, corn, salsa/enchilada flavors, and cheese.

FULL INGREDIENT LIST
Chicken & rice mixture
3 cups cooked shredded chicken
2 cups cooked long-grain white rice
1 can (15 oz / 425 g) black beans, drained and rinsed
1 cup corn kernels, frozen, canned or fresh
1 cup chunky salsa
½ cup sour cream or plain Greek yogurt
1½ cups shredded Mexican-blend cheese
1 small onion, finely diced
2 cloves garlic, minced
1 tbsp olive oil
1 small bell pepper, diced
1–2 tbsp chopped green chiles, optional
Seasoning
2 tsp chili powder
1 tsp ground cumin
1 tsp smoked paprika
½ tsp dried oregano
½ tsp garlic powder
½ tsp onion powder
½ tsp salt, or to taste
¼ tsp black pepper
¼–½ tsp cayenne, optional
Juice of ½ lime
Cheese topping
1½ cups shredded cheddar, Monterey Jack, Colby Jack or Mexican blend
Fresh toppings — these give it the look in your photo
1 avocado, diced
3–4 green onions, sliced
¼ cup chopped fresh cilantro
½ cup salsa or pico de gallo
1 small tomato, diced
Pickled or fresh jalapeños, optional
Lime wedges
Extra shredded cheese, optional
STEP-BY-STEP
1. Prepare the oven
Preheat oven to 375°F / 190°C.
Lightly grease a 9 × 13-inch baking dish.
2. Sauté the vegetables
Heat 1 tablespoon olive oil in a skillet over medium heat.
Add:
diced onion
bell pepper
Cook for about 4–5 minutes, until softened.
Add garlic and cook another 30–60 seconds.
Don’t brown the garlic too much.
3. Make the chicken mixture
Add the cooked shredded chicken.
Stir in:
chili powder
cumin
smoked paprika
oregano
garlic powder
onion powder
salt
pepper
cayenne, if using
Cook for 2–3 minutes so the spices become fragrant.
4. Add the beans and corn
Stir in:
black beans
corn
green chiles
Cook for another 2 minutes.
If using frozen corn, it doesn’t need to be completely thawed.
5. Make it creamy
Turn off the heat.
Add:
cooked rice
salsa
sour cream or Greek yogurt
lime juice
Mix gently.
Taste and adjust the seasoning.
Tip: If the mixture seems dry, add another ¼–½ cup salsa.
6. Assemble the casserole
Spread about half of the mixture into the baking dish.
Sprinkle with about ¾ cup cheese.
Add the remaining chicken-rice mixture.
Spread evenly.
Cover with the remaining cheese.
For an especially cheesy casserole like the picture, you can use up to 3 cups total cheese.
7. Bake
Cover loosely with foil.
Bake at 375°F / 190°C for 15 minutes.
Remove the foil and bake another 10–15 minutes, until:
cheese is completely melted
edges are bubbling
center is hot
For a browned top, switch to broil for 1–2 minutes, watching carefully.
8. Add the fresh toppings
Let the casserole rest for about 5–10 minutes.
Then add:
diced avocado
green onions
cilantro
tomato
salsa
jalapeños
Finish with fresh lime juice.
This is important: don’t bake the avocado. Add it after baking so it stays fresh and creamy.
HOW TO SERVE
Serve large spoonfuls straight from the casserole dish.
Excellent with:
tortilla chips
warm tortillas
Mexican-style salad
roasted vegetables
extra salsa
guacamole
sour cream
lime wedges
For a lighter meal, serve it with a big green salad.
MAKE IT SPICIER
For a hotter version, add:
1 chopped jalapeño
½ tsp cayenne
1–2 tsp chipotle sauce
hot salsa instead of mild salsa
sliced pickled jalapeños on top
For children, omit the cayenne and use mild salsa.
NUTRITION & ALLERGEN INFORMATION
Nuts
This recipe contains no intentional tree nuts or peanuts.
However, if you have a serious nut allergy, check the labels on:
packaged shredded cheese
salsa
taco/seasoning mixes

for manufacturer allergen statements and cross-contact warnings.
Dairy
Contains dairy if you use:
cheese
sour cream
Dairy-free: Use dairy-free shredded cheese and dairy-free yogurt/sour-cream alternative.
Gluten
The basic ingredients are naturally gluten-free, but packaged salsa, seasonings and other processed ingredients should be checked for gluten/cross-contact if you need strict gluten avoidance.

No soy-containing ingredient is necessary, but check processed cheese and packaged products if soy avoidance is important.
APPROXIMATE NUTRITION
Because the exact brands and quantities can vary, these are estimates rather than laboratory values.

MAKE-AHEAD INSTRUCTIONS
Assemble the casserole without the avocado and fresh toppings.
Cover and refrigerate for up to 24 hours.
When ready to bake, remove from the refrigerator and let it sit briefly while the oven preheats.
Because it starts cold, it may require an additional 5–10 minutes of baking.
Add avocado, cilantro, green onion and salsa after baking.
FREEZER INSTRUCTIONS
For best quality, freeze the casserole before adding fresh toppings.
Assemble in a freezer-safe dish.
Cool completely if any ingredients are warm.
Cover tightly.
Freeze for up to about 2–3 months for best quality.
Thaw overnight in the refrigerator.
Bake until thoroughly hot and bubbling.
Add fresh toppings afterward.
Avocado is best added fresh rather than frozen with the casserole.
LEFTOVERS
Refrigerate in a covered container for 3–4 days.
Reheat individual portions in the microwave until steaming hot, or reheat the entire casserole covered in a 350°F / 175°C oven.
Add fresh avocado and salsa after reheating.
RECIPE Q&A
: Can I use rotisserie chicken?
Absolutely. It’s one of the easiest options. Remove the skin and bones and shred the meat.
Q: Can I use leftover rice?
Yes. This recipe is particularly good for leftover cooked rice.
Q: Can I use frozen corn?
Yes. Add it directly to the mixture; there’s no need to thaw completely.
Q: Can I use canned chicken?
Yes, although rotisserie or freshly cooked chicken generally gives better texture.
Q: Why is my casserole dry?
Usually because the rice absorbed too much moisture. Stir in additional salsa, a little broth, or sour cream before baking.
Q: Why is my casserole watery?
The most common causes are wet salsa, insufficiently drained beans/corn, or frozen vegetables releasing excess water.
Drain canned ingredients thoroughly.
Q: Can I make it without sour cream?
Yes. Use Greek yogurt, cream cheese, or simply add extra salsa and cheese.
Q: Can I make it without cheese?
Yes, but it won’t have the same creamy, stretchy texture shown in the photograph. Use a dairy-free cheese alternative if desired.
Q: Can I prepare it with raw chicken?
You can, but I don’t recommend simply substituting raw chicken into these instructions because the cooking time and liquid requirements change. Using cooked chicken makes the recipe much more predictable.
Q: Can I make it low-carb?
Yes. Replace the rice with cauliflower rice and increase the chicken/vegetables. Reduce the corn if you want to lower carbohydrates further.
Q: Is avocado necessary?
No. It’s a topping, not a structural ingredient. But it gives the casserole the fresh, creamy contrast visible in the photo.
Q: Can I make it ahead?
Yes. Assemble it up to a day ahead, refrigerate, then bake when needed.
Q: How do I get the cheese really golden?
Bake uncovered at the end and, if necessary, broil for 1–2 minutes. Watch it constantly because cheese can burn quickly.
Q: Can I make it less spicy?
Use mild salsa, omit cayenne and jalapeños, and use regular chili powder rather than hot chile seasoning.
Q: What gives it the Tex-Mex flavor?
The key combination is chili powder + cumin + paprika + salsa + black beans + corn + cheese + lime.
BEST VERSION OF THE RECIPE
For the closest photo-style result, I’d use:
3 cups shredded rotisserie chicken + 2 cups cooked rice + 1 can black beans + 1 cup corn + 1 cup salsa + ½ cup Greek yogurt + 3 cups total shredded Mexican cheese, then finish it with avocado, green onion, cilantro, tomato and extra salsa.
