Ingredients Notes

  1. Chicken Breast: Lean, high-protein, and versatile, chicken breast works best for this dish. Thighs can also be used for a richer flavor.
  2. Bell Peppers: Choose a mix of red, yellow, and green peppers for vibrant color and a natural sweetness.
  3. Onion: White or yellow onions add a subtle sweetness, while red onions provide a more robust flavor.
  4. Cheese: Shredded Mexican blend or cheddar works well. For a dairy-free option, use a plant-based cheese substitute.
  5. Fajita Seasoning: Use store-bought or homemade for a perfectly spiced dish.
  6. Lime Juice: Adds brightness and balances the richness of the casserole.
  7. Tortillas (optional): Serve on the side or bake them into the casserole for a layered texture.

Variations and Substitutions

  • Protein Options: Substitute chicken with turkey, shrimp, or even plant-based alternatives like tofu or tempeh for a vegetarian option.
  • Spice Level: Adjust heat by adding more chili powder or a dash of cayenne. For a milder version, reduce the spice blend.
  • Veggies: Add zucchini, mushrooms, or corn to increase the veggie content.
  • Low-Carb Option: Skip tortillas and use cauliflower rice or shredded zucchini as the base.
  • Cheese-Free Version: Simply omit the cheese or use a dairy-free alternative for a lighter dish.
  • Toppings: Serve with salsa, guacamole, or Greek yogurt instead of sour cream for added flavor and creaminess.

Storage Options

  • Refrigerator: Store leftovers in an airtight container for up to 3–4 days.
  • Freezer: Freeze portions in freezer-safe containers for up to 2 months. Reheat in the oven at 350°F until warmed through.
  • Meal Prep: Divide into individual containers for easy grab-and-go lunches during the week.
