This hearty chicken fajita casserole transforms traditional fajita flavors into a comforting one-dish meal perfect for busy weeknights. The combination of tender chicken, fluffy rice, and classic Mexican seasonings creates a crowd-pleasing dinner that brings restaurant flavors right to your family table.
I created this recipe during a particularly hectic week when I needed something that would satisfy my family while giving me leftovers for lunches. Now it's requested at least twice a month, especially during sports seasons when we need hearty, reheatable meals.
Ingredients
- Shredded cooked chicken: Provides the protein foundation. Rotisserie chicken works perfectly for time-saving convenience
- Instant rice: Eliminates the need to pre-cook your rice. It absorbs all the delicious flavors as it bakes
- Cream of chicken soup: Creates a rich, creamy base that binds everything together
- Sour cream: Adds tanginess and creaminess that balances the spices perfectly
- Frozen diced onion and bell pepper blend: Saves valuable prep time while adding essential fajita flavors
- Diced tomatoes with chilies: Bring acidity and mild heat. The undrained can provides needed moisture
- Chicken broth: Ensures the rice cooks properly and infuses extra flavor throughout
- Fajita seasoning packet: Delivers authentic Mexican flavor without measuring multiple spices
- Mexican blend cheese: Creates that irresistible melty topping that browns beautifully
Step-by-Step Instructions
- Prepare Your Equipment:
- Preheat your oven to exactly 350°F and take time to thoroughly spray your 9x13 baking dish with nonstick spray, ensuring you cover the corners where sticking often occurs. This temperature allows for perfect rice cooking without drying out the chicken.
- Mix The Casserole:
- In a large mixing bowl, combine chicken, uncooked rice, cream of chicken soup, sour cream, vegetable blend, tomatoes with their juice, broth, seasoning, and half the cheese. Stir thoroughly until every ingredient is evenly distributed, making sure no dry pockets of rice remain. The mixture will look fairly wet, which is necessary for proper rice cooking.
- Transfer And Cover:
- Pour the mixture into your prepared baking dish, using a spatula to spread it into an even layer. Cover tightly with aluminum foil, pressing it firmly around the edges to create a good seal. This traps moisture and heat, ensuring the rice cooks properly.
- Bake Until Rice Is Tender:
- Place the covered dish in your preheated oven for 35 to 45 minutes. Check at the 35-minute mark by carefully lifting the foil and testing if the rice is tender. Different brands of instant rice may require slightly different cooking times. The casserole should be bubbling around the edges when done.
- Add Final Cheese Layer:
- Remove the foil completely and sprinkle the remaining cheese evenly across the top. Return to the oven for approximately 5 more minutes until the cheese is completely melted and just beginning to bubble and brown in spots.

My family's favorite way to enjoy this casserole is with a topping bar of fresh avocado, cilantro, and lime wedges. The brightness of these fresh ingredients complements the rich, savory casserole beautifully. I discovered this combination when trying to use up produce in my refrigerator, and it's been our tradition ever since.
Make-Ahead Options
This casserole works wonderfully as a make-ahead meal. You can assemble the entire dish up to the baking step, cover tightly with foil, and refrigerate for up to 24 hours. When ready to cook, add about 10-15 minutes to the baking time since you're starting with a cold dish. The flavors actually develop nicely during this rest time in the refrigerator.
Customization Ideas
The basic recipe serves as an excellent template for customization. For a spicier version, add a diced jalapeño or substitute pepper jack cheese for part of the Mexican blend. If you prefer a vegetarian option, replace the chicken with two cans of black beans, drained and rinsed. For a lower-carb alternative, cauliflower rice can replace the instant rice, though you'll need to reduce the liquid by approximately half a cup.
Serving Suggestions
This casserole shines when served with simple, fresh accompaniments. A crisp green salad with a lime vinaigrette makes the perfect counterpoint to the rich flavors. For an interactive family meal, create a toppings bar with shredded lettuce, diced tomatoes, sliced avocados, sour cream, and your favorite hot sauce. You can also serve warm flour tortillas on the side for those who might want to create impromptu burritos with the casserole filling.
