This casserole version of your favorite rolled and breaded cordon bleu is so much easier, yet has the exact same flavors.

Chicken cordon bleu is delicious, but let’s be honest, it isn’t very easy to make! So, why not formulate this amazing entree into a super easy casserole? It’s got all the same flavors, and is just as tasty, but is far easier to make. That’s a win in my book!

I love making chicken cordon bleu casserole as an easy dinner during the week. It’s super filling, so I always tend to have leftovers to eat for lunch the next day. I love pairing this easy dinner casserole with mashed potatoes and bacon wrapped green beans. A dinner so full of comfort food!

Why You’ll Love Chicken Cordon Bleu Casserole

• This easy casserole only takes 15 minutes to prep! The rest of the work is done by the oven.

Ingredients needed for this Chicken Cordon Bleu Casserole Recipe

• Shredded Chicken – You can easily make shredded chicken in the Instant Pot or Crock Pot. Or, grab a rotisserie chicken from the grocery store and you can shred that to use in this casserole recipe.
• Milk – I used whole milk in this recipe, but you could use 2% milk or 1% milk if you prefer.
• Sliced Deli Ham – I recommend getting thick cut deli ham! Just get your favorite kind, but you’ll have best results with a high quality deli meat.
• Dijon Mustard – Dijon mustard is that classic chicken cordon bleu taste!
• Shredded Mozzarella – You can buy shredded mozzarella or buy a block to shred yourself. You can also use slices of mozzarella cheese if you’d like!
• Smoked Paprika – Regular paprika will work in a pinch, but smoked paprika really helps bring a lot of flavor into the cheesy sauce
• Panko Breadcrumbs – Be sure you get plain panko crumbs! The ones with seasonings may taste a little off in this recipe.
• Flour – You’ll need a little dash of all-purpose flour in this recipe.
• Butter – Feel free to use salted or unsalted butter, either will work great.
• Lemon Juice – You can either use fresh squeezed lemon juice or use bottled lemon juice.
• Salt and Pepper – These simple seasonings are perfect for this delicious casserole.

How to Make Chicken Cordon Bleu Casserole

Prep the Casserole

Preheat the oven and lightly butter or spray a 9×13 baking dish and set it aside.

Spread the shredded chicken onto the bottom of the baking dish in an even layer and then sprinkle the chopped ham on top of the chicken. Sprinkle shredded cheese over ham and chicken layers.

Make the White Sauce

In a medium sized saucepan, melt the butter over medium heat. Once melted, add the flour and stir until it creates a thick paste.

Once the mixture begins to bubbly, slowly pour in the milk while stirring or whisking to make a smooth sauce. Continue stirring over medium heat until the sauce thickens.

Add the lemon juice, dijon mustard, salt, paprika, and pepper. Bring the sauce to barely a boil and remove from heat.

Pour over the layers of chicken, ham, and cheese.

Top it and Bake it

Melt some butter and then mix in the Panko crumbs. Sprinkle the mixture over the top of the casserole.

Bake for 30-35 minutes and then let cool for 10-15 minutes before serving!
