Pro Tips for Chicken Fajita Casserole

• Cut bell peppers and onions into similar-sized pieces to ensure even cooking and consistent texture throughout the casserole.
• Customize fajita seasoning according to your spice preference by adding more or less to suit individual taste buds.
• Use a meat thermometer to verify chicken reaches 165°F (74°C) for safe consumption and perfectly cooked protein.
• Marinate chicken in fajita seasoning for 30 minutes before baking to enhance overall taste and tenderness.
• Cover the baking dish with foil during initial cooking to retain moisture and prevent chicken from drying out.

Flavorful Variations for Fajita Casserole

• Vegetarian Swap: Replace chicken with firm tofu or black beans for a plant-based protein alternative that maintains the classic fajita flavor profile.
• Seafood Edition: Substitute chicken with shrimp or white fish for a coastal-inspired protein option that keeps the zesty seasoning intact.
• Low-Carb Option: Skip the tortilla chips and use cauliflower rice as a base, reducing carbohydrate content while preserving the essential fajita taste.
• Dairy-Free Modification: Use dairy-free cheese or nutritional yeast instead of traditional shredded cheese to accommodate lactose-sensitive individuals.

Serving Ideas for Chicken Fajita Casserole
