Chicken, ham and cheese — it's a combination that's hard to not to love. Chicken cordon blue can be a bit time-consuming to make: cutting the chicken, stuffing it, breading it, frying and then making a sauce. Sometimes we want everything about a cordon bleu without all the time it takes.
In this recipe, we break down to the basics and cook it all in a casserole. You use cooked rotisserie chicken and simply shred it. You dice ham, Swiss cheese and Parmesan cheese and then make a quick bechamel-like sauce. After mix everything in a casserole dish, top it with bread crumbs, and off to the oven it goes. In 25 minutes, you'll have a meal the whole family will love.
