Ingredients List
Gather the following ingredients to whip up your Fajita Chicken Casserole. Feel free to use substitutions based on your personal taste or dietary requirements:
- 1 ½ pounds boneless, skinless chicken breasts, diced
- 2 tablespoons olive oil
- 1 large onion, thinly sliced
- 1 bell pepper (any color), sliced
- 2 teaspoons chili powder
- 1 teaspoon cumin
- ½ teaspoon smoked paprika
- 1 can (15 oz) black beans, drained and rinsed (or use pinto beans)
- 1 can (14.5 oz) diced tomatoes (preferably with green chilies)
- 1 cup corn (fresh, frozen, or canned)
- 2 cups cooked rice (brown or white for a healthier option)
- 3 cups shredded cheese (Cheddar, Monterey Jack, or a mix)
- Salt and pepper to taste

Timing
Preparation for this comforting Fajita Chicken Casserole takes approximately 15 minutes, followed by a cooking time of about 45 minutes, totaling just 60 minutes for a wholesome dinner. This quick turnaround makes it an efficient option for busy weeknights, especially when compared to other popular casseroles that often require over an hour of cooking alone.
Step-by-Step Instructions
Step 1: Prepare Your Chicken and Vegetables
Start by preheating your oven to 375°F (190°C). While waiting, take a moment to dice the chicken breasts into bite-sized pieces. Slice the onion and bell pepper thinly. A quick tip: cutting your vegetables evenly ensures they cook at the same rate, providing a better texture in your casserole.
Step 2: Sauté Chicken and Vegetables
In a large skillet, heat the olive oil over medium heat. Add the diced chicken and sauté for about 5-7 minutes until it starts to brown. Next, toss in the onion and bell pepper, cooking for an additional 3-5 minutes until they are softened. Stir in chili powder, cumin, smoked paprika, and add a pinch of salt and pepper to taste. This step develops the flavors beautifully.

Step 3: Combine with Remaining Ingredients
Once the chicken and vegetables are ready, remove them from heat. In a large mixing bowl, combine the cooked rice, black beans, diced tomatoes, corn, and the sautéed chicken mixture. Mix everything together until well combined. The blend of textures and flavors will already have you salivating.
Step 4: Layer and Bake
Transfer the mixture into a greased 9×13-inch casserole dish. Top it off with the shredded cheese, covering the entire surface. Place the casserole in the preheated oven and bake for 25-30 minutes, or until the cheese is bubbly and golden brown. This step is crucial—if baked too long, the casserole may dry out.

Common Mistakes to Avoid
To ensure your Fajita Chicken Casserole turns out perfectly, avoid these common mistakes:

- Under-seasoning: Fajitas are known for their bold flavors. Don’t be shy with your spices, as this is essential for a tasty casserole.
- Not letting it rest: Allow the casserole to set for about 5 minutes after baking. This waiting time allows flavors to meld and makes serving easier.
Storing Tips for the Recipe
Leftover Fajita Chicken Casserole can be stored easily. Here are some tips to ensure your meal stays fresh:
- Cooling: Allow the casserole to cool completely before storing.
