I was an adult before I ever experienced Chicken Cordon Bleu. And it was love at first bite! Amazing!! So over the years I have made it, several times.
This past week I cooked a Spiral Ham, and with only two of us eating, I had a lot leftover! So what could I do with the leftovers? I decided to make Chicken Cordon Bleu, as a casserole! I made a sauce like I would for regular individual chicken cordon bleu, but made it all in a 9×13” baking dish.
My casserole was a hit! We loved it. Of course, we had leftovers, which I froze. I will be making this again because we so enjoyed it. I hope you’ll give it a try sometime.
