Ingredients

Scale

Main Protein:

  • 2 pounds (907 grams) boneless, skinless chicken breasts

Vegetables and Aromatics:

  • 1 red bell pepper, sliced
  • 1 green bell pepper, sliced
  • 1 yellow bell pepper, sliced
  • 1 onion, sliced
  • 1 can diced tomatoes

Seasonings and Toppings:

  • 2 tablespoons olive oil
  • 1 packet fajita seasoning
  • 1 cup shredded cheddar cheese

Instructions

  1. Prepare a cozy casserole dish and preheat the oven to a toasty 375°F, creating the perfect environment for a sizzling meal.
  2. Transform chicken into bite-sized morsels and sear them in olive oil over medium heat, developing a rich golden-brown exterior that promises deep flavor.
  3. Sprinkle fajita seasoning over the chicken, then introduce vibrant bell peppers and onions to the skillet, allowing them to dance and soften until vegetables reach a tender, translucent state.
  4. Pour diced tomatoes into the skillet, creating a robust sauce that will simmer and meld the flavors for approximately 5 minutes, intensifying the dish’s aromatic profile.
  5. Carefully transfer the fragrant chicken and vegetable mixture into the prepared baking dish, ensuring an even distribution that promises a harmonious bite.
  6. Generously blanket the entire surface with a layer of shredded cheese, which will transform into a golden, molten landscape during baking.
  7. Slide the casserole into the preheated oven and bake for 20 minutes, watching for the cheese to melt into a bubbly, appetizing crust that signals the dish is ready to be devoured.

Notes

  • Swap chicken for tofu or plant-based protein alternatives to create a vegetarian version that’s equally delicious and satisfying.
  • Use low-fat cheese or dairy-free cheese options to reduce calories and accommodate lactose-intolerant dietary needs.
  • Boost nutrition by adding extra vegetables like zucchini, spinach, or cauliflower to increase fiber and vitamin content without changing the core flavor profile.
  • Control spice levels by adjusting fajita seasoning or using mild versions for sensitive palates while maintaining the authentic Mexican-inspired taste.
