  • 1 tablespoon vegetable oil

Vegetables and Toppings

  • 2 medium bell peppers, cut into strips
  • 1 medium yellow onion, sliced
  • 1 ½ cups shredded cheese
  • Fresh chopped cilantro for garnish

Instructions

  1. Preheat Oven: Preheat your oven to 400°F (200°C) to prepare for baking the casserole.
  2. Season Chicken: In your baking dish, place the chicken breasts and evenly coat them with the fajita seasoning and vegetable oil. Use your hands to ensure the seasoning is well distributed across the chicken surfaces.
  3. Add Vegetables: Arrange the sliced bell peppers and onions evenly on top of the seasoned chicken. Optionally, sprinkle a little extra fajita seasoning over the vegetables for added flavor.
  4. Top with Cheese: Generously sprinkle the shredded cheese over the chicken and vegetables, covering them well to ensure melting and flavor fusion during baking.
  5. Bake: Place the baking dish uncovered in the preheated oven and bake for 25-30 minutes, or until the chicken is cooked through and the cheese is bubbly and golden.
  6. Serve: Remove from the oven and garnish with fresh chopped cilantro if desired. Serve immediately while warm and enjoy your flavorful Chicken Fajita Casserole.
