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 the oven heats up, grab a 9x13 inch baking dish and generously grease it with butter or cooking spray. This will ensure that your Chicken Cordon Bleu Casserole doesn't stick and comes out beautifully.
Step 2: Cook the Pasta
Bring a large pot of salted water to a boil, then add your penne pasta. Cook the pasta for about 8-10 minutes, stirring occasionally until al dente; it should be firm yet cooked through. Once done, drain the pasta and transfer it to the prepared baking dish where it will form the base of your casserole.
Step 3: Prepare the Cheese Sauce
In a medium saucepan, melt 3 tablespoons of butter over medium heat. Once melted, add the minced garlic and sauté for 1-2 minutes until fragrant, being careful not to let it brown. Stir in an equal amount of flour to create a roux, cooking for another minute before gradually whisking in the chicken broth and heavy cream for a creamy cheese sauce.
Step 4: Thicken the Sauce
Continue to whisk the sauce over medium heat until it thickens, which should take about 2-3 minutes. Once you've achieved a velvety consistency, remove the saucepan from heat and stir in the Dijon mustard, brown sugar, apple cider vinegar, salt, and pepper, followed by the Swiss cheese until completely melted and smooth.
Step 5: Assemble the Casserole
Layer the cooked chicken pieces evenly over the pasta in the baking dish. Then, sprinkle the chopped ham generously atop the chicken layer. Pour the creamy cheese sauce over the entire mixture, spreading it evenly to ensure every bite of the Chicken Cordon Bleu Casserole is flavor-packed.
Step 6: Create the Crunchy Topping
In a small bowl, combine panko bread crumbs with a couple of tablespoons of melted butter and a sprinkle of garlic powder. Mix well until the crumbs are evenly coated, then sprinkle this mixture generously over the cheese sauce layer for a crunchy topping that will become golden and satisfying once baked.
Step 7: Bake the Casserole
Place your assembled Chicken Cordon Bleu Casserole in the preheated oven and bake uncovered for 15-20 minutes. You’re looking for a bubbly casserole that has a beautifully golden topping—this should indicate that it's cooked through and ready to be enjoyed.
Step 8: Rest Before Serving
After removing the casserole from the oven, let it rest for a few minutes to allow the sauce to set slightly. This will help each serving hold its shape better when you scoop it out. Once rested, it’s ready to serve and delight family or guests with its rich flavors and comforting textures!

Expert Tips for Chicken Cordon Bleu Casserole
- Pasta Perfection: Ensure your penne pasta is cooked al dente, as it will continue to soften during baking. Under-cook it slightly for the best texture.
