Notes
Rotisserie Chicken Convenience: Utilizing cooked rotisserie chicken saves time and adds flavor to the casserole. Shred the chicken into bite-sized pieces for easy incorporation into the dish. If you don't have rotisserie chicken on hand, you can also use leftover cooked chicken or quickly cook chicken breasts or thighs specifically for this recipe.
Customize Vegetable Selection: While the recipe suggests frozen peas and canned corn, feel free to customize the vegetable selection based on personal preferences or what you have available. Consider using mixed vegetables, diced bell peppers, or broccoli florets for added color and nutrition. Fresh, frozen, or canned vegetables can all work well in this casserole.
Crunchy Topping Enhancement: The combination of shredded cheddar cheese and French-fried onions creates a deliciously crunchy topping for the casserole. To ensure a crispy texture, add the French fried onions halfway through the baking process, allowing them to become golden brown and perfectly crispy. This adds a satisfying contrast to the creamy texture of the casserole. Optionally, sprinkle some extra cheese on top for an extra cheesy finish before adding the French fried onions.
