This is an easy casserole recipe:

My family loves it when I make hearty casseroles like Cheeseburger Casserole and Easy Taco Casserole for dinner. I knew this Chicken Cordon Bleu Casserole would not only be a hit with the entire family because they already love my original Chicken Cordon Bleu recipe, but I knew I would love making it because it is a super easy casserole.

This recipe is so easy, in fact, that it almost feels like a cheat. You see, the most difficult part of making Chicken Cordon Bleu is the fact that you have to pound the raw chicken breasts and roll them around ham and Swiss.  Not a lot of people enjoy handling raw chicken and the technique of stuffing the chicken breasts can be a bit challenging.

Next time you’re grocery shopping, just pick up a precooked rotisserie chicken. Everyone knows they taste fantastic on their own, but when you combine them with a few other ingredients to make this easy casserole, your mouth  won’t stop watering!

You could make the same kind of easy casserole for a traditional chicken parmesan recipe. Instead of using raw chicken, you could pick up a rotisserie chicken and have yourself an easy dinner casserole using similar ingredients!

What’s in this Casserole?

Chicken Cordon Bleu Casserole is basically Chicken Cordon Bleu, deconstructed. I knew I wanted to use the same ingredients as my original Chicken Cordon Bleu recipe, and I wanted it to have the same crispy topping and creamy sauce as well.

The basic Chicken Cordon Bleu recipe consists of chicken wrapped around ham and Swiss cheese, then coated with some kind of bread crumb topping, and baked to perfection. The cream sauce is optional, but if you ask me I think it’s a must. For whatever reasons, the saltiness of the ham and the meltiness of the Swiss cheese perfectly compliment the chicken. I guarantee that if you make Chicken Cordon Bleu Casserole for dinner, your entire family will love it and want you to add it to your regular rotation.

  • While the casserole is cooking, make the sauce. In a saucepan melt the butter, then add the flour and whisk together. Cook for several minutes while continually whisking to avoid burning. 
  • Gradually whisk in milk. Continue to heat until the milk bubbles and begins to thicken, about 3-5 minutes. Remove from heat and whisk in dijon, parmesan, and thyme. Add salt and pepper to taste.
  • To serve, pour warm sauce over casserole.

    I haven’t made this yet, but I plan to, tonight! I am Animal-Based Carnivore and will swap out Pork Panko for your crunchy topping, and cream for milk and thickener in the sauce. But this looks so good, low carb, easy and keeps me in the Ketogenic state! Thank you!

    1. Hi Judy, My costco carries an organic McCormick garlic herb blend mix in the spice section. I use it all the time. It’s a blend of blend of garlic, Italian herbs, red pepper and paprika.
