Ingredients
- Uncooked long grain white rice: brings heartiness and soaks up all the delicious flavors Select a fresh bag for fluffy results
- Minced garlic: delivers robust savory depth always choose plump firm cloves
- Chopped onion: adds sweet flavor as it bakes yellow or white onions work equally well
- Chicken broth: infuses the base with extra flavor opt for low sodium to control saltiness
- Chicken breasts: light and lean they become juicy and tender choose ones without excess fat
- Black beans: bring fiber and creaminess look for cooked well drained beans
- Frozen corn: adds a touch of sweetness and color make sure to fully defrost for even cooking
- Jarred salsa: provides instant tang and spice choose your favorite brand or spice level
- Chili powder: gives gentle heat and a distinct Tex Mex kick use fresh if possible
- Paprika: adds color and earthy flavor smoked paprika gives even more depth
- Cheddar cheese: melts to form a gooey topping sharp cheddar works beautifully here
Instructions
- Prep the oven and dish:
- Preheat your oven to three hundred fifty degrees and grab a large twelve by nine inch casserole dish
- Build the flavor base:
- In your casserole dish layer uncooked rice top with minced garlic and chopped onion Then pour in the chicken broth Stir everything together thoroughly so the rice gets fully coated and spread evenly
- Layer in main ingredients:
- Place cubed chicken breasts evenly over the rice mixture Add black beans scattered across the top followed by defrosted corn and salsa Finally sprinkle chili powder and paprika for an even distribution of flavor Try your best to keep the rice on the bottom well covered with wet ingredients so it steams and cooks properly
- Add the cheesy top:
- Evenly distribute shredded cheddar cheese across the surface to ensure a bubbly golden crust
- Bake covered:
- Cover the dish tightly with foil and bake for forty five minutes This helps steam the rice and cook everything through
- Finish uncovered:
- Remove foil and bake for an additional ten minutes or until the cheese is fully melted and slightly bubbly at the edges

When I was a kid my mom would double the corn for extra sweetness and golden color That little trick still makes me smile and I carry it into every batch
Storage Tips
Let the casserole cool completely before storing Slice into portions and keep in an airtight container in the fridge for up to four days For longer storage wrap tightly and freeze for up to three months Thaw overnight in the fridge or reheat straight from frozen covered with foil
Ingredient Substitutions
Jazz things up by swapping brown rice for white just add extra broth and extend cooking time Both rotisserie chicken and leftover turkey work beautifully for a “clean out the fridge” night You can even use pinto beans in place of black beans for a slightly creamier texture
Serving Suggestions
I love scattering fresh cilantro and a dollop of sour cream just before serving Tortilla chips or a leafy green salad make perfect accompaniments For spice lovers add hot sauce or diced jalapeños on the side
Cultural Context
This one pan casserole draws inspiration from Tex Mex flavors you find across the Southwest It is a favorite for busy families since it delivers all the taste of enchiladas or burritos with none of the fuss Every household puts their own spin on it making it a feel good classic
Seasonal Adaptations
Add diced bell pepper or zucchini in summer months Swap in roasted pumpkin or butternut in autumn for a sweet twist Garnish with fresh tomatoes when they are in season

Neighbors have asked for the recipe more than once after a single taste This dish traveled to a neighborhood potluck and not a single scoop was left Even picky kids tend to ask for seconds which is always the real mark of a family favorite
