Ingredients
  

For the Casserole
  • 2 lbs Chicken Breasts/Thighs Opt for thighs for richer flavor
  • 3 cups Bell Peppers Mix red, yellow, and green for color
  • 1 medium Onion Yellow or white onions work best
  • 1 can Diced Tomatoes with Green Chilies Canned for convenience
  • 2 tbsp Olive Oil For marinating chicken
  • 2 tbsp Lime Juice Fresh juice yields the best taste
  • 1/4 cup Fresh Cilantro For garnish
For the Topping
  • 2 cups Shredded Cheese Cheddar, Monterey Jack, or pepper jack
  • 2 tbsp Homemade Fajita Seasoning Adjust cayenne for heat preference

Equipment

  • 9x13 Baking Dish
  • Mixing Bowl
  • Aluminum foil

Method
 

Step-by-Step Instructions
  1. Preheat your oven to 400°F (200°C) and lightly grease a 9x13 baking dish with olive oil.
  2. Combine chicken strips with olive oil, lime juice, and fajita seasoning mix. Marinate for about 10–15 minutes.
  3. Add sliced bell peppers and onions to the marinated chicken and toss until well-coated.
  4. Layer half of the chicken-vegetable mixture in the baking dish. Top with half of the diced tomatoes and 1 cup of shredded cheese, then repeat layers.
  5. Cover with foil and bake for 20 minutes. Remove foil and bake for another 10–15 minutes until cheese is melted and golden.
  6. Optionally, broil for 2–3 minutes at the end for a crispy cheese layer.
  7. Let it rest for 10–15 minutes before garnishing with cilantro and serving.
