Step-by-Step Instructions

Prep the Baking Dish:

Lightly grease a nine by thirteen inch casserole dish so the casserole lifts out cleanly

Mix the Filling:

In a large bowl combine shredded chicken uncooked instant rice cream of chicken soup sour cream onion and pepper blend undrained tomatoes with chilies chicken broth fajita seasoning and one cup of shredded cheese. Stir until every grain of rice and bite of chicken is coated

Layer and Bake Covered:

Pour the mixture into the greased casserole dish and spread evenly to the corners. Cover tightly with aluminum foil to trap in steam and bake for thirty five minutes so the rice gets tender and flavors meld

Cheesy Topping:

Remove the foil after the first bake then sprinkle the remaining cheese evenly across the top for those golden bites. Return the casserole dish to the oven uncovered for about ten more minutes until the cheese is melted and bubbly

Cool and Serve:

Take the casserole out of the oven and let it stand for several minutes before serving so everything sets slightly and scoops up neatly

Pin it

My favorite ingredient in this dish is the bag of frozen onion and peppers. It always reminds me of my mom’s shortcut soups on busy school nights and brings bursts of sweetness and color to every bite. Last winter my daughter helped pour in the frozen blend and declared the stars of dinner were the peppers

Storage Tips

This casserole saves the day on busy evenings because leftovers keep for up to three days tightly covered in the fridge. For longer storage portion slices into airtight containers and freeze up to two months. Reheat covered in the oven at three hundred fifty degrees until hot or zap individual portions in the microwave until steaming

Ingredient Substitutions

If you do not have rotisserie chicken just bake or poach three large boneless breasts until cooked through then shred. Leftover turkey works wonders too. For vegetarians swap in cooked black beans or chickpeas and use a plant-based cream of chicken soup. If you only have plain shredded cheese add a pinch of cumin or chili powder for that Tex-Mex kick

Serving Suggestions

Spoon generous portions over a bed of crisp lettuce for a fajita salad twist. Serve with tortilla chips for scooping or offer as a filling side with grilled corn or roasted sweet potatoes. Add a dollop of guacamole or extra sour cream and a squeeze of lime right before serving to brighten up the flavors even more

Cultural Context

Fajita-flavored dishes stem from Tex-Mex cuisine where grilled meats and chili-spiced veggies star in family style meals. This casserole swaps the skillet for the oven and brings all the sizzle and comfort of fajitas to a one-pan bake. It has become a staple in potluck culture especially across the southwestern United States thanks to its crowd pleasing flavors and shareable nature
