🔥 Why These Ingredients Work
Every ingredient plays a role:

- Fajita seasoning adds bold, smoky, slightly spicy flavor without needing a dozen different spices.
- Bell peppers and onions bring color, sweetness, and nutrition.
- Cream of mushroom soup gives it a creamy, luxurious texture with minimal effort.

- Rice acts as the perfect base, soaking up all the savory juices.
Together, they create a balanced, flavor-packed meal in one comforting bake.
👩🍳 Step-by-Step Instructions
Follow these simple steps for a foolproof casserole:
Step 1: Preheat and Prep
Preheat your oven to 375°F (190°C).
Lightly grease a 9×13-inch baking dish with cooking spray or a thin layer of olive oil. Set aside.
Step 2: Cook the Chicken
In a large skillet, heat the olive oil over medium-high heat.
Add the chicken pieces and sprinkle them evenly with the fajita seasoning mix.
Cook for about 5–7 minutes, stirring occasionally, until the chicken is browned and cooked through.
Pro Tip: Don’t overcrowd the pan. Cook in batches if needed for better browning.
Step 3: Sauté the Veggies
Once the chicken is cooked, add the sliced red and green bell peppers and onion to the same skillet.
Cook for another 5 minutes, stirring often, until the veggies are tender-crisp and slightly caramelized.
The peppers and onions will soak up any remaining seasoning and juices from the chicken — flavor jackpot!
Step 4: Mix the Casserole
In a large bowl, combine:
- The cooked chicken and veggies
- The can of cream of mushroom soup
- Shredded cheddar cheese
- Cooked rice
Mix everything together gently but thoroughly until fully combined.
Season to taste with a little salt and pepper if needed.
Step 5: Assemble and Bake
Pour the mixture into the prepared baking dish.
Spread evenly and top with a little extra cheese if you’re feeling indulgent.
Bake uncovered for 20–25 minutes, or until the casserole is bubbly around the edges and golden on top.
Step 6: Rest and Serve
Let the casserole cool for 5 minutes before scooping out generous servings.
The flavors meld as it rests, and it cuts cleaner when slightly cooled.
🌟 Pro Tips for the Best Casserole
- Use freshly cooked rice: Warm rice mixes more easily with the other ingredients.
- Season carefully: Fajita seasoning is salty, so taste before adding extra salt.
- Shred your own cheese: Pre-shredded cheese often has anti-caking agents that don’t melt as nicely.
- Add a crunchy topping: Sprinkle crushed tortilla chips or panko bread crumbs on top for a fun texture!
🥗 Nutritional Highlights

- High in protein: Thanks to chicken and cheese.
- Loaded with vegetables: Bell peppers and onions bring vitamin C, antioxidants, and fiber.

❓ Frequently Asked Questions
Can I make it ahead?
Yes! Assemble the casserole up to a day ahead, cover tightly, and refrigerate. Bake when ready.
Can I freeze it?
Absolutely. Cool completely, wrap tightly, and freeze for up to 2 months. Thaw overnight in the fridge before reheating.
What can I use instead of cream of mushroom soup?
Cream of chicken or cream of celery soup works well. Or make a homemade roux with broth and cream!
Can I use leftover cooked chicken?
Yes! Just toss it with fajita seasoning before mixing it into the casserole.
