Chicken Cordon Bleu Casserole
This creamy, crowd-pleasing casserole delivers generously on cheesy, savory flavor—but requires a fraction of the fuss of classic chicken cordon bleu. The key to this chicken cordon bleu casserole’s incredible, bubbly richness is the stovetop cheese sauce made with Swiss and Gruyère. (If you have trouble finding Gruyère, simply substitute the same amount of Swiss.) Additionally, toasting the breadcrumb topping on the stovetop will keep them exceptionally crispy during baking; so while it may seem like an unnecessary extra step in the casserole’s assembly, it does make for a tastier final product. We call for shredded rotisserie chicken here, but rest assured—this is a great casserole recipe for using leftover cooked chicken. In fact, you can even cut the recipe in half and bake the chicken cordon bleu casserole in an 8-x8-inch square pan for a smaller crowd. One final pro-tip from our test kitchens: You can finely chop the chicken and ham and turn this recipe into an awesome dip for a party.
