Cordon Bleu Casserole Tips

Why is it called cordon bleu?

Cordon bleu literally translates to "blue ribbon" in French. It is said that Cordon Bleu was a wide blue ribbon (denoting excellence) worn by members of the highest order of knighthood. The term has since been applied to food that is prepared of the highest standards. Interestingly, many sources indicate that traditional chicken cordon bleu did not originate in France. They say it was first invented in Switzerland as a schnitzel filled with cheese. Either way, most cooks agree breaded poultry stuffed with ham and cheese is delicious! This casserole is a tasty riff on that same concept.

How can I adjust this cordon bleu casserole recipe?

There are some easy variations you can apply to this recipe to suit your tastes. You can use cubed pancetta or crumbled bacon in place of the ham. Cooked cubed chicken is a great substitute if you don’t have turkey. Shredded provolone works well in place of the Swiss.

Soft Bread Crumbs
To make soft bread crumbs, tear bread into pieces and place in a food processor or blender. Cover and pulse until crumbs form. One slice of bread yields 1/2 to 3/4 cup crumbs.
