When I finally retired from teaching after nearly four decades, I expected quiet mornings, long walks, and more time for books. But what I didn’t expect was how much I’d fall in love with my own kitchen all over again. It’s funny—during the school year, dinner often meant quick fixes, leftover rotisserie chicken, and a prayer. Now, I have time to play, experiment, and, sometimes, rediscover dishes I once tossed together in a hurry.
One afternoon, I stared at a bowl of shredded chicken and some leftover fajita veggies in the freezer. I didn’t want tacos or another wrap. I wanted something that felt warm, complete, and easy to serve to my daughter and her two boys, who were dropping by later.
So I stirred in rice, threw in some pantry staples, and baked it all into a bubbling casserole. That night, everyone went back for seconds—and even my picky 9-year-old grandson asked for more (that never happens with anything besides pizza).
Since then, this Fajita Chicken Casserole has become a regular in my kitchen. It’s got all the bold flavors of fajitas with the cozy feel of a baked dish. It’s colorful, filling, and a joy to share—just like the recipes I grew up with, only easier.
Short Description
A warm, flavorful casserole that combines tender shredded chicken, rice, fajita veggies, and creamy goodness—perfect for busy nights or family meals. Easy to prep, comforting to eat.
Key Ingredients
- 4 cups shredded cooked chicken (about 3 large breasts)
- 2 cups instant rice
- 1 can (10.5 oz) cream of chicken soup
- 1 cup sour cream
- 1 cup frozen diced onion and bell pepper blend
- 1 can (10 oz) diced tomatoes with chilies, undrained
- 1 ½ cups chicken broth
- 1 packet (1.12 oz) fajita seasoning
- 1 bag (8 oz) shredded Mexican blend cheese (about 2 cups)
Tools Needed
- 9×13-inch casserole dish
- Large mixing bowl
- Mixing spoon or spatula
- Aluminum foil
- Oven
Cooking Instructions
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Lightly spray a 9×13-inch casserole dish with nonstick cooking spray to prevent sticking.
Step 2: Mix the Filling
In a large bowl, combine the shredded chicken, uncooked instant rice, cream of chicken soup, sour cream, frozen onion and bell pepper blend, diced tomatoes with chilies (including their liquid), chicken broth, fajita seasoning, and half of the shredded cheese. Stir until well mixed.
Step 3: Assemble the Casserole
Pour the mixture evenly into the prepared casserole dish. Use a spatula to spread it out and level the top.
Step 4: Bake Covered
Cover the dish tightly with aluminum foil. Bake for 35 minutes. This gives the rice time to cook and absorb all the flavor.
Step 5: Add the Cheese & Bake Again
Remove the foil and sprinkle the remaining cheese evenly over the top. Return the dish to the oven and bake for another 10 minutes, or until the cheese is melted and bubbly.
Step 6: Rest & Serve
Let the casserole sit for 5–10 minutes before serving. This helps it set and makes scooping much easier.

Mistakes to Avoid & Solutions
Mistake 1: Using regular rice instead of instant
Solution: Only use instant rice, or the casserole won’t cook properly. If you only have regular rice, cook it separately before mixing.
Mistake 2: Not thawing frozen veggies
Solution: Use the frozen blend as-is, but break up any big chunks. They’ll cook through in the oven, but evenly spreading them helps avoid soggy spots.
Mistake 3: Skipping the foil cover
Solution: Don’t skip the foil in the first bake. It traps steam so the rice cooks through. Without it, you’ll end up with undercooked rice and dry chicken.
Mistake 4: Using pre-shredded cheese right from the fridge
Solution: Let your cheese sit at room temp for 5–10 minutes so it melts more smoothly and evenly.
Mistake 5: Overbaking
Solution: Keep an eye on the last 10 minutes. When the cheese is golden and bubbly, it’s ready. Overbaking can make the edges dry and crusty.
Serving and Pairing Suggestions
This dish is a full meal on its own, but you can dress it up or round it out:
Add a side of black beans or a green salad with lime vinaigrette
Top with sliced avocado, fresh cilantro, or a squeeze of lime
Serve buffet-style at gatherings with tortilla chips and salsa on the side
Pair with iced tea, a cold Mexican beer, or sparkling water with lime
Storage and Reheating Tips
Refrigerate: Store leftovers in an airtight container in the fridge for up to 4 days.
Freeze: Freeze cooled portions in freezer-safe containers for up to 2 months.
Reheat in Oven: Cover with foil and bake at 325°F until warmed through, about 20–25 minutes.
Microwave: Reheat individual portions in the microwave in 1-minute bursts, stirring in between. Add a splash of broth if it seems dry.
FAQs
1. Can I use rotisserie chicken?
Yes! It’s a great shortcut. Just shred and measure out 4 cups.
2. Can I make it ahead of time?
Absolutely. Assemble it the night before, cover, and refrigerate. Add 5 extra minutes to the baking time.
3. Is it spicy?
It has a mild kick from the diced chilies and fajita seasoning. For less spice, use plain diced tomatoes instead.
4. What if I don’t have sour cream?
You can swap with plain Greek yogurt for a lighter option or use a mix of cream cheese and milk.
5. Can I double the recipe?
Yes, just use two 9×13 dishes and rotate them halfway through baking for even cooking.
Tips & Tricks
Use a mix of white and dark chicken meat for richer flavor.
Add a handful of corn or black beans for extra texture.
Sprinkle crushed tortilla chips on top before baking for added crunch.
If your casserole seems too thick, add ¼ cup more broth before baking.
Let it rest after baking—this helps the rice set and makes cleaner servings.
Recipe Variations
Spicy Southwest Twist
Swap in pepper jack cheese for extra heat and stir in ½ teaspoon chili powder. Add chopped jalapeños before baking.
Vegetarian Version
Skip the chicken and add 2 cups of black beans and 1 ½ cups roasted vegetables like zucchini or mushrooms. Use cream of mushroom soup instead of chicken.
Low-Carb Version
Replace the rice with 3 cups cooked riced cauliflower. Reduce broth to ¾ cup since cauliflower releases moisture. Bake uncovered for the final 20 minutes to avoid sogginess.
Breakfast Fajita Bake
Replace chicken with cooked breakfast sausage, omit the rice, and add 6 beaten eggs into the mix before baking. Serve with salsa and avocado slices.
Final Thoughts
No matter how many times I make Fajita Chicken Casserole, I’m still amazed by how effortlessly it comes together and how happy it makes everyone around the table. That golden cheese, those warm spices, the creamy filling—it all feels like a hug from your past and your present at once.
It’s not fancy, but it doesn’t have to be. It’s food that feels like home. And after years in a classroom and now years in a kitchen, I’ve learned that kind of food is the best kind. If this dish finds a place in your family’s regular rotation, I’d be tickled pink.
