Ingredients

Scale

Main Ingredients

  • 1 ½ pounds skinless, boneless chicken breasts, cut into small pieces
  • 2 tablespoons fajita seasoning
  • 1 tablespoon vegetable oil
  • 2 medium bell peppers, sliced into strips
  • 1 medium yellow onion, sliced
  • 1 ½ cups shredded cheese (your choice)
  • Fresh chopped cilantro for garnish
  • 1 pinch salt (optional)

Instructions

  1. Preheat: Preheat your oven or cooker so it’s ready when you finish prepping the ingredients.
  2. Prepare Chicken: Cut chicken breasts into bite-sized pieces and place them in a bowl.
  3. Season Chicken: Sprinkle fajita seasoning over the chicken pieces and stir to coat evenly.
  4. Cook Chicken: Heat vegetable oil in a skillet or a sauté mode if using a cooker over medium-high heat. Add the chicken and cook until browned and no longer pink, about 5-6 minutes.
  5. Sauté Vegetables: Add the sliced bell peppers and onion to the skillet with the chicken. Cook until the vegetables just start to soften, around 3-4 minutes.
  6. Assemble Casserole: If using skillet, transfer the mixture to a greased 9×13 inch baking dish. If your pot is oven-safe, you can continue in the same pot.
  7. Add Cheese: Sprinkle the shredded cheese evenly over the chicken and vegetables in the baking dish or pot.
  8. Bake: Bake uncovered in the preheated oven for 15-20 minutes until the casserole is bubbly and the cheese is melted and golden.
  9. Garnish and Serve: Remove from oven, garnish with fresh chopped cilantro, and serve warm.

Notes

  • Store leftovers in the refrigerator for 3-4 days or freeze for longer storage.
  • Reheat gently to preserve the texture of the chicken and vegetables.
  • You can customize the cheese choice to your preference, such as cheddar, Monterey Jack, or a blend.
  • For spicier flavor, add additional fajita seasoning or diced jalapeños.
