Chicken Cordon Bleu Casserole Recipe

This creamy, crunchy Easy Chicken Cordon Bleu Casserole is made with shredded chicken, savory ham, and Swiss cheese, ready in 50 minutes. The golden panko crust gives way to a bubbling, rich cheese sauce underneath. I love making this when I want comfort food without the hassle of rolling chicken breasts.

What Makes This Version Different

Traditional cordon bleu is amazing but breading individual chicken breasts takes too much patience for a busy weeknight. I found that layering the ingredients delivers the exact same flavor profile with a fraction of the effort.

My biggest mistake early on was using a thin milk sauce that turned watery in the oven. Now, I use a thick Dijon cream base that binds everything together perfectly.

Easy Chicken Cordon Bleu Casserole Ingredients

• 4 cups cooked chicken, shredded
• 8 oz deli ham, chopped
• 8 oz Swiss cheese, shredded
• 1 can (10.5 oz) cream of chicken soup
• 1/2 cup whole milk
• 1 tbsp Dijon mustard
• 1 cup panko breadcrumbs
• 4 tbsp unsalted butter, melted

How To Make Easy Chicken Cordon Bleu Casserole

1. 1. Prep the Oven: Preheat your oven to 350°F and grease a 9×13 inch baking dish.
2. 2. Mix the Sauce: Whisk the cream of chicken soup, whole milk, and Dijon mustard together in a medium bowl until smooth.
3. 3. Layer the Base: Spread the shredded chicken evenly across the bottom of the prepared baking dish.
4. 4. Add Ham and Cheese: Scatter the chopped deli ham over the chicken, then pour the sauce evenly on top. Sprinkle the shredded Swiss cheese over the sauce.
5. 5. Prepare the Topping: Toss the panko breadcrumbs with the melted butter in a small bowl until fully coated.
6. 6. Bake and Serve: Sprinkle the buttery crumbs over the cheese. Bake for 30 to 35 minutes until the edges are bubbling and the top is golden brown.

Recipe Tips

• Shred your own cheese: Pre-shredded Swiss contains anti-caking agents that prevent it from melting smoothly into the casserole.
• Use rotisserie chicken: Grabbing a pre-cooked chicken saves at least twenty minutes of active prep time.
• Don’t skip the Dijon: The mustard cuts through the richness of the cheese and cream sauce perfectly.
• Toast the panko: If you want an extra crunchy top, briefly toast the buttery panko in a skillet before baking.

What To Serve With Chicken Cordon Bleu Casserole

This heavy casserole pairs best with light, acidic sides to balance the rich cheese sauce. A simple green salad with a sharp vinaigrette or steamed asparagus tossed in lemon juice works perfectly. Roasted green beans are also a great option to soak up any extra sauce.

How To Store

Keep leftover casserole in an airtight container in the fridge for up to four days. You can also freeze unbaked portions for up to three months. Thaw overnight in the fridge before baking, adding an extra ten minutes to the cook time.

FAQs

Can I use leftover holiday ham?

Yes, thickly diced leftover baked ham works incredibly well and adds a great smoky flavor to the dish.

Do I have to use Swiss cheese?

Gruyere or provolone are excellent substitutes if you dislike the flavor of traditional Swiss cheese.

Why did my casserole turn out runny?

Using chicken that wasn’t fully drained or vegetables with high water content can thin out the sauce during baking.

Can I make this ahead of time?

You can assemble everything except the panko topping up to two days in advance. Add the breadcrumbs right before baking so they stay crisp.
