Chicken Cordon Bleu Casserole Ingredients
For the Pasta Base
• Penne Pasta – This is the perfect foundation for the casserole; for a gluten-free option, use gluten-free pasta instead.
For the Filling
• Cooked Chicken – Provides hearty protein; feel free to use rotisserie chicken to save time or swap with shredded turkey.
• Chopped Ham – Adds a savory note; you can use turkey ham or omit it for a vegetarian version and include extra veggies.
• Shredded Swiss Cheese – Delivers that classic creamy flavor; feel free to switch it up with cheddar, gouda, or mozzarella for a different taste.
For the Creamy Sauce
• Heavy Cream – Contributes richness to the sauce; low-fat cream or half-and-half can substitute for a lighter option.
• Butter – Essential for creating the cheese sauce; consider a plant-based butter for a dairy-free choice.
• Dijon Mustard – Adds a tangy layer to the sauce; whole grain mustard works as a suitable substitute if needed.
• Brown Sugar – Balances flavors; honey or maple syrup makes a great natural sweetener alternative.
• Apple Cider Vinegar – Introduces brightness; white vinegar or lemon juice can also be used if you don't have apple cider vinegar on hand.
• Garlic – Enhances overall flavor; fresh minced garlic is favored, but you can substitute garlic powder in a pinch.
For the Crunchy Topping
• Panko Bread Crumbs – Offers a delightful crunch; gluten-free panko ensures the casserole stays gluten-free while maintaining that crispy texture.

Step‑by‑Step Instructions for Chicken Cordon Bleu Casserole
Step 1: Preheat Oven
Begin by preheating your oven to 400°F (200°C). While it warms up, grab a 9x13-inch baking dish and grease it lightly with cooking spray or butter. This ensures your Chicken Cordon Bleu Casserole comes out seamlessly, with no sticking, ready for that delicious reveal.
Step 2: Cook Pasta
In a large pot, boil salted water and add your penne pasta, cooking it for 8-10 minutes until it's al dente. Once the pasta is tender yet firm, drain it and transfer it immediately to your greased baking dish, making a perfect base for the casserole layers to come.
Step 3: Make Cheese Sauce
In a medium saucepan over medium heat, melt 4 tablespoons of butter. Add minced garlic and sauté for about 1 minute until fragrant. Next, whisk in ¼ cup of flour, then slowly stir in 2 cups of chicken broth and 1 cup of heavy cream, cooking for 2-3 minutes until the sauce thickens. Stir in Dijon mustard, brown sugar, vinegar, and salt, followed by the shredded Swiss cheese until melted and smooth.
Step 4: Assemble Casserole
Once your cheese sauce is ready, layer the cooked chicken over the pasta in the baking dish. Scatter the chopped ham on top of the chicken, ensuring even coverage, then pour the glorious cheese sauce evenly over the layers, allowing it to seep in and coat everything nicely.
Step 5: Prepare Topping
In a small bowl, mix 1 cup of panko breadcrumbs with 2 tablespoons of melted butter and a sprinkle of garlic powder, combining until the panko is coated. Sprinkle this crispy mixture generously over the top of the casserole, imparting that perfect crunch that complements the creamy layers beneath.
Step 6: Bake
Place your assembled Chicken Cordon Bleu Casserole in the preheated oven and bake for 15-20 minutes. You'll know it's ready when the top is bubbly and golden brown, creating a beautiful contrast to the creamy filling inside. Allow it to sit for a few minutes before diving in for a perfect serving!

Chicken Cordon Bleu Casserole Recipe FAQs
What should I look for when selecting the chicken for this casserole?
Absolutely! When choosing chicken for your Chicken Cordon Bleu Casserole, I recommend going for cooked chicken that is moist and tender. Rotisserie chicken is an excellent option as it’s fully cooked and packed with flavor. Ideally, you want to avoid pieces with dark spots or questionable texture, which could indicate staleness.
How should I store leftovers from the casserole?
Very! Store any leftovers in an airtight container in the fridge for up to 3 days. Make sure to let the casserole cool completely before placing it in the fridge. This helps retain moisture and flavor, allowing you to enjoy those creamy, cheesy bites again!

What can I do if my cheese sauce isn’t thickening?
If you find your cheese sauce isn’t thickening, don’t worry! Let it continue to simmer for an extra minute or two, stirring frequently. If it remains too thin, you can create a quick slurry by mixing 1 tablespoon of cornstarch with 2 tablespoons of cold water, whisking it into your sauce until you reach the desired consistency. It’s all about the perfect creamy texture!
Is it okay to modify the recipe for dietary restrictions?
Very! This casserole is quite flexible. For gluten-free options, simply swap the penne with gluten-free pasta. You can also use dairy-free alternatives for the butter and cheese, like plant-based butter or vegan cheese. If anyone in your family has allergies, check labels carefully, and feel free to get creative with substitutions!

When it’s time to reheat, cover your casserole with foil and place it in a preheated oven at 350°F (175°C) for about 20-25 minutes until heated through. This method helps maintain that creamy texture, ensuring every bite tastes just as wonderful as the first time!
