Chicken Cordon Bleu Casserole

This Chicken Cordon Bleu Casserole recipe is so much easier to make than the traditional way of preparing this dish. It's hearty, flavorful, and takes around 45 minutes to prepare from start to finish. I like to serve it with this honey mustard sauce because they really complement one another.

My husband, Scott, loves chicken cordon bleu. I used to make it for him all the time, but I hadn't in quite some time. So recently he mentioned how much he missed this dish, hinting of course that I should make some soon.

I must've gotten a little heavy-handed when I was pounding the chicken breasts because some of them tore. I thought to myself, why not make a chicken cordon bleu casserole instead?

I thought I had come up with a unique twist on this classic chicken cordon bleu recipe until I looked online and saw it was already done. Oh well, as King Solomon said, "There is nothing new under the sun."

This dish had so much flavor, especially when drizzled with honey mustard sauce. And now that I've prepared chicken cordon bleu both ways, I'm never going back to the traditional method!

🛒 What You Need For This Recipe

🔖 Ingredients & Substitutions

• Chicken: You'll need approximately 3 to 4 lbs of boneless, skinless, chicken breasts. If you'd like, you can use boneless, skinless chicken thighs instead.
• Ham: Depending on the thickness and size of the cut of deli ham you use, you can either do one or two layers.
• Cheese: Add one or two packages of Swiss cheese. If you like blue cheese, add some of that too! If you don't like either, substitute mozzarella, provolone, or Monterey Jack cheese.
• Breading: I used Ritz crackers, however, Panko breadcrumbs can be substituted.
• Seasoning: A combination of Tony Chachere's Creole Seasoning and garlic powder. You can also add other spices, or dried herbs such as oregano, thyme, or rosemary.
• French Fried Onions: French fried onions to mix with the bread crumbs.

🍗 How to Make This Chicken Cordon Bleu Casserole Recipe

Preheat oven to 400 degrees F.

In a bowl, crush 1 sleeve of Ritz crackers along with ¾ cup of French fried onions, then mix with ½ teaspoon of Tony Chachere's Creole Seasoning and ½ teaspoon of garlic powder. Pour 3 tablespoons of melted butter over the mixture and stir to combine. 

Dry chicken breasts with paper towels, then slice horizontally to make 2 thin chicken breasts. Add one at a time to a large ziplock bag and seal. Pound with the flat side of a kitchen mallet until thin. Once done, season chicken breasts with 2 teaspoons of Tony Chachere's Creole Seasoning and 1 teaspoon of garlic powder.

Pro Tip: Optionally, you can use boneless, skinless, chicken thighs. Depending on their thickness, they may not need to be pounded.

Brush a 9x13 casserole dish with 1 tablespoon of melted butter, then arrange half of the chicken breasts, making sure the bottom of the pan is completely covered. Add a layer of ham and 2 layers of Swiss cheese slices. If you like blue cheese, add some!

Pro Tip: If using thick slices of ham, you only need one layer. If using thinly sliced ham, layer half under the cheese and the other half over the cheese.

Arrange the remaining chicken over the cheese and sprinkle with an even layer of the crushed cracker-French fried onion mixture.

Cover the baking dish with aluminum foil, seal around the edges, and bake in the preheated oven for 20 minutes. Remove foil and bake for 10 more minutes or until golden brown on top and cooked through. Allow to set for a few minutes, then slice into 8 portions. Garnish with chopped parsley for a pop of color.

🍽 Serving Suggestions

Serve your chicken cordon bleu casserole with any of the following: green salad, pear and goat cheese salad, roasted beet root salad, grilled asparagus, or some Instant Pot scalloped potatoes. Whatever you do, don't forget the honey mustard sauce! If you don't have time to make the sauce, serve with Dijon mustard.

👩🏼‍🍳 Pro Tips

• If you like it extra cheesy, double the Swiss cheese.
• After adding the first layer of chicken, I like to add the second layer of chicken over it to make sure I have enough for both layers. Sometimes you have to move the chicken pieces around to fill in the gaps.
• Store leftovers in an airtight container in the refrigerator for up to 4 days.
• To freeze the casserole, don't add the breadcrumb mixture. Cover the unbaked casserole with plastic wrap and aluminum foil. Place in the freezer for up to 3 months. Thaw overnight in the fridge, prepare and add topping, then bake according to the recipe baking instructions.
