Chicken Cordon Bleu Casserole (No Pasta, No Canned Soup)Chicken cordon bleu casserole gives you all the flavor of the classic, tender chicke, ham, and a creamy Dijon cheese sauce, but skips the rolling, stuffing, and frying. Instead, everything is layered in a baking dish and topped with buttery panko that bakes up crisp and golden. It’s rich, cozy, and comes together in about 15 minutes using simple ingredients you probably already have.

All the Flavor of Cordon Bleu, None of the Fuss
Traditional chicken cordon bleu is made of thinly pounded chicken breast stuffed with ham and cheese, which is then rolled up, breaded and pan or deep-fried and served with a mustard cream sauce. The casserole version captures all the flavors without the steps.

Start with a rotisserie chicken,(or you can roast your own chicken, or use leftover turkey) then add cooked ham, (leftover or from the deli). Since the meat is already cooked, all you have to do is add a cheesy sauce and let it get all bubbly and crispy on top.

Serve this French inspired dish on it’s own, or over egg noodles. Just throw in a light and refreshing salad and you have a dish that takes no time but is nice enough to serve for company. It’s also great with steamed broccoli, the broccoli’s texture is perfect for dipping in extra sauce.

This was good for a rainy cool spring dinner. Even the grumpy teen who said he didn’t like chicken cordon bleu ate quite a bit of it. Served with rice, broccoli, and sourdough bread. I could see maybe baking it with cooked rice too? Might try that next time.

Always a win when you can get a teenager to try something new! Glad you liked it.
