Step-by-Step Instructions

Prep the Oven and Dish:

Set your oven to 350 degrees so it is fully heated when you are ready Begin with a large casserole dish about nine by twelve inches to give the rice enough space to cook evenly

Layer the Base:

Spoon the uncooked rice into the bottom of your dish then sprinkle the minced garlic and chopped onion across the top Pour chicken broth over everything and stir gently to ensure the rice is fully moistened Every grain should be wet so you get no uncooked patches later

Assemble Toppings:

Scatter the cubed chicken pieces over the rice mixture followed by the black beans and defrosted corn Spread these ingredients in an even layer Then pour the salsa across the top and sprinkle with chili powder and paprika Use the back of a spoon to gently nudge everything so the rice stays tucked on the bottom and does not dry out

Add Cheese:

Evenly scatter the shredded cheddar cheese across the top of your casserole It should completely cover the surface so it melts into a golden crust

Bake Covered:

Cover the casserole dish tightly with foil to trap steam This is crucial as it helps the rice to absorb all the liquids Bake for forty five minutes and avoid peeking so you do not let out needed moisture

Finish Uncovered:

Remove the foil and return the casserole to the oven for another ten minutes The cheese will turn bubbly and a little bit golden This last step makes a big difference for the perfect finish

Rest and Serve:

Let the casserole sit for ten minutes after baking before scooping This rest lets the rice finish absorbing liquid and makes serving much cleaner

Pin

The salsa is my not so secret weapon in this dish I love the way it seasons everything in one step and creates just enough sauce for the rice Sometimes my family will argue over who gets the cheesiest corners it is a sure sign of success

Storage Tips

Let your casserole cool fully before transferring to airtight containers It will keep in the fridge for up to four days Reheat portions in the microwave or oven for best results Freezes well too just slice into portions first so you can grab one or two servings at a time

Ingredient Substitutions

Brown rice works if you increase the broth and baking time by about ten to fifteen minutes Rotisserie or leftover chicken can be subbed for raw just reduce the initial baking by ten minutes Any salsa will do so try green tomatillo or fire roasted for a twist Colby Jack or Monterey Jack can stand in for cheddar if desired

Serving Suggestions

Top with fresh cilantro chopped green onions or a scoop of sour cream Serve alongside a simple green salad or sautéed veggies Warm tortillas or tortilla chips are always popular at my table too

Cultural Context

This kind of chicken casserole takes inspiration from classic Tex Mex favorites like arroz con pollo and enchilada bake The one dish format makes it especially popular in American homes because it is filling simple and shares all the vibrant flavors of the Southwest
