Step-by-Step Instructions

Here’s how to make Fajita Chicken Casserole:

  2. Cook the Chicken: Heat olive oil in a large skillet over medium heat. Add the cubed chicken breast and cook for 5-7 minutes, or until the chicken is fully cooked and no longer pink in the center. Season with chili powder, paprika, cumin, garlic powder, salt, and pepper. Stir to coat the chicken evenly in the spices.
  3. Cook the Vegetables: Add the sliced bell pepper and onion to the skillet with the chicken and cook for another 3-4 minutes, or until the vegetables begin to soften.

Assemble the Casserole:

  1. Combine the Ingredients: In a large mixing bowl, combine the cooked chicken and vegetables, salsa, sour cream, and cooked rice. Stir everything together until well mixed.
  2. Add the Cheese: Fold in ½ cup of shredded cheddar cheese and ½ cup of Monterey Jack cheese into the mixture.
  3. Transfer to Baking Dish: Pour the mixture into the prepared casserole dish, spreading it evenly.
  4. Top with Cheese: Sprinkle the remaining ½ cup of cheddar cheese and ½ cup of Monterey Jack cheese on top of the casserole.

Bake and Serve:

  1. Bake: Bake in the preheated oven for 25-30 minutes, or until the cheese is melted and bubbly and the casserole is heated through.
  2. Garnish and Serve: Remove the casserole from the oven and let it cool for 5 minutes. Garnish with fresh cilantro and sliced jalapeños, if desired. Serve hot.

How to Serve Fajita Chicken Casserole

  • For Meal Prep: This casserole is perfect for meal prep! Serve individual portions with a side of rice or vegetables for a complete meal.

Additional Tips for Fajita Chicken Casserole

Here are some tips to ensure your Fajita Chicken Casserole is perfect every time:

  • Use Rotisserie Chicken: For a quicker option, substitute the cubed chicken breast with shredded rotisserie chicken.

  • Add More Veggies: Feel free to add extra vegetables like zucchini, corn, or black beans for more flavor and texture.
  • Leftover Rice: Use leftover rice to save time. If you don’t have any, simply cook some rice while prepping the other ingredients.
  • Cheese Variations: Swap the cheddar and Monterey Jack for other melting cheeses like pepper jack for an extra kick or mozzarella for a more mild, gooey texture.
  • Don’t Overcook the Chicken: Be careful not to overcook the chicken to keep it tender and juicy in the casserole.
  • Make it Ahead: You can prepare the casserole ahead of time, cover it tightly with foil, and refrigerate for up to 24 hours before baking. Add a few extra minutes to the bake time if cooking from the fridge.
