For the Main Ingredients
• Cooked Chicken – The heart of the dish; substitutable with rotisserie chicken for convenience.
• Chopped Ham – Adds a savory, salty flavor that complements the chicken; turkey can be used as an alternative.

Step‑by‑Step Instructions for Chicken Cordon Bleu Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). While it warms, take a moment to grease a 9x13 baking dish with butter or cooking spray to ensure easy removal of your delicious Chicken Cordon Bleu Casserole once baked.
Step 2: Cook the Pasta
In a large pot, bring salted water to a boil and add your penne pasta. Cook the pasta until it reaches al dente, about 8-10 minutes, stirring occasionally. Once cooked, drain the pasta and transfer it directly to the greased baking dish, providing a sturdy base for your casserole layers.
Step 3: Prepare the Cheese Sauce
In a medium saucepan over medium heat, melt the butter. Add minced garlic and sauté until fragrant, about 1 minute. Gradually stir in gluten-free flour, cooking for an additional minute, then whisk in the chicken broth and heavy cream. Cook until the mixture thickens, about 3-5 minutes, and remove from heat.
Step 4: Add Flavor to the Sauce
To your thickened sauce, stir in Dijon mustard, brown sugar, apple cider vinegar, salt, and pepper. Mix well to combine all flavors, then gradually fold in the shredded Swiss cheese until it completely melts, creating a creamy and rich sauce that will elevate the Chicken Cordon Bleu Casserole.
Step 5: Layer the Ingredients
Evenly layer the cooked chicken over the pasta in the baking dish, followed by the chopped ham. Pour the luscious cheese sauce evenly over these layers, ensuring every piece is coated in that scrumptious sauce. This step brings all the key elements together before baking!
Step 6: Prepare the Topping
In a small bowl, combine panko breadcrumbs with melted butter and garlic powder until well-coated. This mixture will provide the perfect crunchy topping for your casserole. Evenly sprinkle the breadcrumb mixture over the cheese sauce, ensuring coverage for a delightful crunch.
Step 7: Bake the Casserole
Carefully place the prepared Chicken Cordon Bleu Casserole in the preheated oven. Bake for about 15-20 minutes, or until the top is golden brown and the casserole is bubbling at the edges. Once baked, remove it from the oven and allow it to sit for a few minutes before serving to enhance the flavors.

Expert Tips for Chicken Cordon Bleu Casserole
-
Cool Before Baking: Allow the casserole to sit at room temperature if it's been refrigerated. This helps it bake evenly and achieve the perfect texture.

Add Nutritional Boost: Incorporate cooked veggies like spinach or peas for added nutrients and color, enhancing both flavor and health benefits.
-
Storage Savvy: Keep leftovers fresh by tightly wrapping them in foil or placing them in an airtight container. They last up to three days in the fridge!

Chicken Cordon Bleu Casserole Recipe FAQs
What type of pasta should I use for the casserole?
I recommend using penne pasta since it holds the sauce well and cooks evenly. You want to cook it until al dente, around 8-10 minutes, as it will continue cooking in the oven. If you're feeling adventurous, you could try using gluten-free penne or rigatoni to accommodate dietary needs!
How can I store leftover Chicken Cordon Bleu Casserole?
Simply store your leftovers in an airtight container in the fridge for up to 3 days. This way, you can easily enjoy a quick meal throughout the week without losing any of that delicious flavor. Just make sure to let it cool to room temperature before sealing it tight!
Can I freeze the Chicken Cordon Bleu Casserole?
Absolutely! To freeze, tightly wrap the casserole in plastic wrap and then in aluminum foil to prevent freezer burn. It can be stored for up to 3 months. When you're ready to enjoy it again, reheat in a preheated oven at 350°F (175°C) for about 20-25 minutes, covered with foil to maintain moisture. This allows it to heat evenly and taste just as delicious!
What should I do if my cheese sauce is too thick or too thin?
If your cheese sauce ends up too thick, you can whisk in a bit more chicken broth or heavy cream to thin it out to your desired consistency. On the other hand, if it's too thin, allow it to simmer on the stovetop for a few more minutes until it thickens up. Be patient; stirring continuously helps achieve that creamy texture you want!
Are there any dietary considerations I should keep in mind?
Yes! This recipe can easily be made gluten-free by using gluten-free pasta and flour as instructed. If you have specific allergies, like dairy, consider using dairy-free cheese alternatives. Always check labels to ensure ingredients meet your dietary needs. If you have pets, it’s best to keep leftovers out of their reach, as items like ham and cheese can be harmful to them.
