Cheesy Baked Chicken Fajita Casserol

Introduction

The Cheesy Baked Chicken Fajita Casserole is a fusion of Tex-Mex flavors wrapped in the cozy comfort of a baked dish. Instead of assembling fajitas at the table, everything is layered in a casserole dish — juicy chicken breasts, sautéed bell peppers, onions, and a rich blanket of melted cheese. It’s easy to prepare, feeds a crowd, and fills your kitchen with irresistible aromas.

Ingredients

 (Serves 4–6)

• Chicken & Vegetables
  
  • 3 large chicken breasts (about 700–800g), boneless & skinless
  • 1 large red bell pepper, sliced into strips
  • 1 large green bell pepper, sliced into strips
  • 1 large yellow bell pepper, sliced into strips
  • 1 medium onion, thinly sliced
  • 3 tbsp olive oil
• Seasoning Mix
  
  • 2 tsp chili powder
  • 1 tsp smoked paprika
  • 1 tsp cumin powder
  • 1 tsp garlic powder
  • ½ tsp oregano
  • 1 tsp salt
  • ½ tsp black pepper
• Casserole & Cheese Layer
  
  • 1 cup shredded cheddar cheese
  • ½ cup shredded mozzarella cheese
  • ½ cup sour cream
  • Fresh cilantro (for garnish)
  • Optional: 1 fresh lime, cut into wedges

Instructions

1. Preheat Oven
   Set your oven to 200°C (400°F).
2. Prepare Chicken
   Slice chicken breasts into halves horizontally (to cook evenly). Rub with half of the seasoning mix.
3. Sauté Vegetables
   In a skillet, heat olive oil over medium heat. Add onions and bell peppers, sprinkle remaining seasoning, and cook for 4–5 minutes until slightly softened.
4. Sear Chicken
   In the same skillet, sear the chicken for 2–3 minutes per side until golden (it will finish cooking in the oven).
5. Assemble Casserole
   Place chicken in a baking dish. Spread sautéed peppers and onions on top. Add dollops of sour cream, then sprinkle cheddar and mozzarella evenly.
6. Bake
   Bake uncovered for 15–20 minutes until the chicken is cooked through and cheese is melted and bubbly.
7. Serve
   Garnish with fresh cilantro and a squeeze of lime. Serve with warm tortillas, rice, or salad.

History

This casserole takes inspiration from Tex-Mex fajitas, a dish that originated in Texas in the 1930s among Mexican ranch workers. Traditional fajitas used skirt steak grilled over an open flame, served with onions, peppers, and tortillas. Over time, chicken versions became popular, and the “casserole” twist emerged in American home kitchens to simplify weeknight cooking while keeping those vibrant flavors.

Formation

 (How the Dish Comes Together)
