This satisfying chicken fajita casserole turns classic fajita taste into a warming all-in-one dish that's perfect for crazy weeknights. When you mix juicy chicken, light rice, and traditional Mexican spices, you get a family-friendly dinner that brings restaurant-quality taste straight to your kitchen table.
I came up with this dish during a super busy week when I needed something my family would enjoy that would also give me extra food for lunch. These days they ask for it at least twice monthly, especially when sports are in season and we need filling meals we can warm up again.
Ingredients
- Shredded cooked chicken: Forms the main protein base. Grab a store-bought rotisserie chicken to save yourself tons of time
- Instant rice: Means you won't need to cook rice beforehand. It soaks up all the yummy flavors while baking
- Cream of chicken soup: Makes a thick, smooth base that holds everything in place
- Sour cream: Gives a tangy creaminess that works great with the spices
- Frozen diced onion and bell pepper blend: Cuts down on prep work while adding must-have fajita taste
- Diced tomatoes with chilies: Add some zing and gentle heat. Don't drain them – the liquid helps cook everything
- Chicken broth: Makes sure the rice cooks right and spreads flavor throughout
- Fajita seasoning packet: Gives you real Mexican flavor without measuring lots of different spices
- Mexican blend cheese: Creates that can't-resist melty top that gets perfectly golden
Step-by-Step Instructions
- Get Your Stuff Ready:
- Heat your oven to 350°F and completely coat your 9x13 baking dish with cooking spray, making sure to get the edges where food often sticks. This temp lets the rice cook perfectly without drying out your chicken.
- Combine Everything:
- In a big bowl, mix together your chicken, uncooked rice, cream of chicken soup, sour cream, veggie mix, tomatoes with their liquid, broth, seasoning, and half the cheese. Stir it all up until everything's well mixed with no dry rice spots. The mix will seem pretty wet, but that's needed for the rice to cook right.
- Put It In The Dish:
- Pour everything into your greased baking dish and spread it out evenly with a spatula. Cover the dish tightly with foil, pressing down on the edges to seal it well. This keeps moisture and heat inside so your rice cooks properly.
- Cook Until The Rice Gets Soft:
- Put the covered dish in your hot oven for 35 to 45 minutes. At 35 minutes, carefully peek under the foil to see if the rice is soft. Different brands of quick rice might need different cooking times. You'll know it's done when it's bubbling around the edges.
- Top With Remaining Cheese:
- Take off the foil and sprinkle the rest of your cheese all over the top. Pop it back in the oven for about 5 more minutes until the cheese melts completely and starts to bubble and brown a little.

My family loves eating this casserole with fresh toppings like avocado, cilantro, and lime wedges. These bright add-ons really complement the rich, savory dish. I stumbled on this combo when I was trying to use up stuff in my fridge, and now we can't eat it any other way.
Make-Ahead Options
You can totally prep this dish ahead of time. Just put everything together up to the baking part, wrap it tight with foil, and keep it in the fridge for up to 24 hours. When you're ready to cook it, add about 10-15 minutes to your baking time since you're starting with a cold dish. The flavors actually get better during this time in the fridge.
Customization Ideas
Think of this basic recipe as a starting point for making it your own. Want it spicier? Throw in a chopped jalapeño or swap some of the Mexican cheese for pepper jack. Going meatless? Replace the chicken with two cans of black beans, drained and rinsed. Watching carbs? Try cauliflower rice instead of instant rice, but cut back on the liquid by about half a cup.
Serving Suggestions
This dish works best with simple, fresh sides. Try a green salad with lime dressing to balance out the rich flavors. For a fun family dinner, set up a toppings station with lettuce, chopped tomatoes, avocado slices, sour cream, and hot sauce. You can also put out warm flour tortillas so folks can make impromptu burritos with the casserole filling if they want.
