What is chicken cordon bleu casserole made of?

Chicken Cordon Bleu Casserole is made of shredded cooked chicken (often rotisserie), diced ham, creamy cheese sauce, and Swiss or mozzarella cheese. Many recipes add a crunchy topping of breadcrumbs or crackers to elevate the texture.

Can I use rotisserie chicken for this casserole?

Absolutely! Rotisserie chicken is ideal for Chicken Cordon Bleu Casserole. It’s already cooked, well-seasoned, and saves time in the kitchen while still delivering amazing flavor and tenderness.

What cheese is best for chicken cordon bleu casserole?

Swiss cheese is the traditional option for its slightly nutty flavor, but mozzarella, Gruyère, or a cheddar mix also works beautifully. A combo of Swiss and cream cheese adds richness without overpowering the dish.

How do you keep the casserole from getting watery?

Pat down the chicken and ham with paper towels before layering. Also, use a thickened sauce and avoid adding too much moisture. Let the casserole rest 10 minutes after baking for a perfectly set texture.
