Trust me, this Chicken Fajita Casserole will become a regular on your dinner rotation!

Ingredients:

• 1.5 lbs boneless, skinless chicken breasts, cut into bite-sized pieces
• 1 large onion, sliced
• 2 bell peppers (any color), sliced
• 1 packet (1 oz) fajita seasoning
• 1 tbsp olive oil
• 1 (10.75 oz) can condensed cream of mushroom soup
• 1 (10 oz) can diced tomatoes and green chilies (Rotel), undrained
• 1 cup shredded cheddar cheese
• 1 cup shredded Monterey Jack cheese
• 1/2 cup sour cream
• 1/4 cup chopped cilantro, for garnish (optional)
• Tortilla chips, for serving
• Optional toppings: guacamole, salsa, extra sour cream

Preparing the Chicken and Vegetables

1. First, let’s get our chicken ready. In a large bowl, toss the bite-sized chicken pieces with the fajita seasoning. Make sure every piece is nicely coated for maximum flavor!
2. Now, heat the olive oil in a large skillet over medium-high heat. Once the oil is shimmering, add the seasoned chicken. Cook the chicken until it’s no longer pink inside and has a nice golden-brown color on the outside. This usually takes about 5-7 minutes, depending on the size of your chicken pieces. Be careful not to overcrowd the pan; if necessary, cook the chicken in batches to ensure even cooking. Overcrowding can lower the pan temperature and result in steamed, rather than seared, chicken.
3. Remove the cooked chicken from the skillet and set it aside in a clean bowl. Don’t worry about cleaning the skillet just yet; we’re going to use it for the vegetables!
4. Add the sliced onion and bell peppers to the same skillet. Cook them over medium heat, stirring occasionally, until they are softened and slightly caramelized. This usually takes about 8-10 minutes. The onions should become translucent and the peppers should be tender-crisp. If the vegetables start to stick to the skillet, add a tablespoon of water or chicken broth to deglaze the pan. This will also add extra flavor!
5. Once the vegetables are cooked to your liking, remove them from the skillet and add them to the bowl with the cooked chicken.

Creating the Casserole Mixture

1. In a large bowl, combine the cooked chicken and vegetables.
2. Add the condensed cream of mushroom soup and the can of diced tomatoes and green chilies (Rotel) to the bowl. Stir everything together until well combined. The cream of mushroom soup will act as a binder, holding all the ingredients together, while the Rotel will add a nice kick of heat and flavor.
3. Now, add 1/2 cup of the shredded cheddar cheese and 1/2 cup of the shredded Monterey Jack cheese to the mixture. Stir again to incorporate the cheese. This will make the casserole extra cheesy and delicious!
4. Finally, stir in the sour cream. The sour cream will add a creamy tanginess to the casserole, balancing out the richness of the cheese and the spiciness of the Rotel.

Assembling and Baking the Casserole

1. Preheat your oven to 350°F (175°C).
2. Grease a 9×13 inch baking dish with cooking spray or a little bit of olive oil. This will prevent the casserole from sticking to the dish and make it easier to clean up later.
3. Pour the chicken and vegetable mixture into the prepared baking dish, spreading it evenly.
4. Sprinkle the remaining 1/2 cup of cheddar cheese and 1/2 cup of Monterey Jack cheese evenly over the top of the casserole. Make sure to cover the entire surface with cheese for a beautiful, golden-brown topping.
5. Bake in the preheated oven for 20-25 minutes, or until the cheese is melted and bubbly and the casserole is heated through. The top should be lightly golden brown.
6. Remove the casserole from the oven and let it cool for a few minutes before serving. This will allow the cheese to set slightly and prevent it from being too runny.

Serving and Enjoying

1. Garnish the casserole with chopped cilantro, if desired.
2. Serve the Chicken Fajita Casserole with tortilla chips for scooping. The crunchy tortilla chips are the perfect complement to the creamy, cheesy casserole.
3. Offer optional toppings such as guacamole, salsa, and extra sour cream for your guests to customize their servings.
4. Enjoy! This Chicken Fajita Casserole is a crowd-pleaser that’s perfect for weeknight dinners, potlucks, or game day gatherings.

Tips and Variations:

• Spice it up: If you like your food extra spicy, add a pinch of cayenne pepper or a dash of hot sauce to the chicken and vegetable mixture. You can also use a spicier variety of Rotel.
• Add beans: For a heartier casserole, add a can of drained and rinsed black beans or pinto beans to the mixture.
• Use different cheese: Feel free to experiment with different types of cheese, such as pepper jack, Colby jack, or even a Mexican cheese blend.
• Make it vegetarian: Substitute the chicken with black beans, corn, and extra vegetables for a vegetarian version.
• Make it ahead: You can assemble the casserole ahead of time and store it in the refrigerator for up to 24 hours. Just add a few extra minutes to the baking time to ensure it’s heated through.
• Freezing instructions: To freeze the casserole, assemble it in a freezer-safe dish and wrap it tightly with plastic wrap and aluminum foil. Freeze for up to 3 months. Thaw overnight in the refrigerator before baking as directed.
• Low-carb option: Serve the casserole over cauliflower rice or zucchini noodles instead of tortilla chips for a low-carb meal.
• Grilling the vegetables: For a smoky flavor, grill the onions and bell peppers before adding them to the casserole.
• Using leftover chicken: This recipe is a great way to use up leftover cooked chicken. Simply shred the chicken and add it to the casserole mixture.
• Adding corn: A can of drained sweet corn adds a touch of sweetness and texture to the casserole.

* Cheese Lover’s Dream: Feel free to experiment with different types of cheese. Monterey Jack, pepper jack, or even a blend of cheddar and mozzarella would all be delicious. Don’t be shy about adding an extra layer of cheese on top for an even cheesier experience!

* Vegetarian Variation: Easily adapt this recipe for vegetarians by substituting the chicken with black beans, pinto beans, or a combination of both. You can also add some crumbled tofu or tempeh for extra protein.
