Ingredients Notes
- Chicken Breast: Lean, high-protein, and versatile, chicken breast works best for this dish. Thighs can also be used for a richer flavor.
- Bell Peppers: Choose a mix of red, yellow, and green peppers for vibrant color and a natural sweetness.
- Onion: White or yellow onions add a subtle sweetness, while red onions provide a more robust flavor.
- Cheese: Shredded Mexican blend or cheddar works well. For a dairy-free option, use a plant-based cheese substitute.
- Fajita Seasoning: Use store-bought or homemade for a perfectly spiced dish.
- Lime Juice: Adds brightness and balances the richness of the casserole.
- 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
