Origin and Cultural Significance

Chicken fajitas originated from Tex-Mex cuisine, where grilled strips of seasoned meat are traditionally served with sautéed peppers and onions in warm tortillas. Over the years, home cooks transformed these popular flavors into casseroles, making them even easier to prepare for families and large gatherings.

Fajita Chicken Casserole preserves the smoky, savory taste of traditional fajitas while adding the creamy richness of a baked casserole. It’s a modern comfort food that combines convenience with the vibrant flavors of Tex-Mex cooking.

Ingredients

Main Ingredients

  • 2 pounds boneless, skinless chicken breasts, cut into bite-sized pieces
  • 3 bell peppers (red, green, and yellow), sliced
  • 1 large onion, sliced
  • 8 ounces cream cheese, softened
  • 1 cup sour cream
  • 1 cup salsa
  • 2 cups shredded Mexican cheese blend or cheddar cheese
  • 2 tablespoons fajita seasoning
  • 1 teaspoon garlic powder
  • 1 teaspoon smoked paprika
  • Salt and black pepper to taste
  • 2 tablespoons olive oil

Optional Topping

  • Chopped cilantro
  • Sliced jalapeños
  • Green onions
  • Diced avocado

Servings

Serves 6–8 people.

Optional Additions

Customize your casserole with:

  • Black beans
  • Sweet corn
  • Diced tomatoes
  • Cooked rice
  • Cauliflower rice
  • Mushrooms
  • Spinach
  • Pepper Jack cheese
  • Crushed tortilla chips
  • Fresh lime juice
  • Hot sauce

Tips for Success

  • Slice the peppers evenly so they cook uniformly.
  • Use rotisserie chicken to save preparation time.
  • Allow the cream cheese to soften before mixing.
  • Don’t overcook the chicken before baking, as it will continue cooking in the oven.
  • Cover with foil if the cheese browns too quickly.
  • Let the casserole rest for 10 minutes before serving for easier slicing.
  • Freshly shredded cheese melts more smoothly than pre-shredded cheese.

Instructions

Step 1: Prepare the Oven

Preheat your oven to 375°F (190°C).

Lightly grease a 9×13-inch baking dish.

Step 2: Prepare the Chicken

In a large bowl, combine:

  • Chicken pieces

  • Pepper

Toss until evenly coated.

Step 3: Prepare the Creamy Mixture

In another bowl, mix together:

  • Cream cheese
  • Sour cream
  • Salsa

Stir until smooth.

Step 4: Assemble the Casserole

Spread the seasoned chicken into the prepared baking dish.

Add the sliced bell peppers and onions.

Pour the creamy salsa mixture evenly over the top.

Sprinkle generously with the shredded cheese.

Step 5: Bake

Bake uncovered for 35–40 minutes, or until the chicken reaches an internal temperature of 165°F (74°C) and the cheese is melted, bubbly, and lightly golden.

Step 6: Garnish and Serve

Allow the casserole to rest for 10 minutes.

Garnish with cilantro, sliced jalapeños, green onions, or avocado if desired.

Serve warm.
