How to Make Chicken Cordon Bleu Casserole

Creating a chicken cordon bleu casserole is surprisingly straightforward, requiring just a few steps to layer ingredients and bake to golden perfection. This thorough guide will assist you in navigating the procedure. 

Ingredients

• 4 cups cooked chicken, shredded or cubed (rotisserie chicken works great!)
• 2 cups diced ham (use deli ham or leftover holiday ham)
• 2 cups shredded Swiss cheese (or a Swiss-Gruyère blend for extra flavor)
• 8 oz egg noodles, cooked al dente (or penne for a heartier texture)
• 1 can (10.5 oz) cream of chicken soup (or homemade for a fresher taste)
• 1 cup of sour cream (or, for a lighter alternative, Greek yogurt)1/2 cup milk (whole or 2% for creaminess)
• 1 tbsp Dijon mustard (adds a tangy kick)
• 1 tsp garlic powder
• 1 tsp onion powder
• To taste, add salt and pepper. 
• 1 cup panko breadcrumbs (optional, for a crunchy topping)
• 2 tbsp melted butter (for the breadcrumb topping)
• Fresh parsley, chopped (for garnish)

Step-by-Step Instructions

1. Preheat the oven: Set the oven temperature to 175°C (350°F). Grease a 9 x 13-inch baking dish with non-stick spray or butter.
2. Cook the pasta: Boil egg noodles (or your chosen pasta) until al dente, about 6-8 minutes. After draining, set aside. 
3. Mix the creamy base: In a large bowl, whisk together cream of chicken soup, sour cream, milk, Dijon mustard, garlic powder, onion powder, salt, and pepper until smooth.
4. Combine the main ingredients: Add the cooked pasta, shredded chicken, diced ham, and 1.5 cups of Swiss cheese to the creamy mixture. Stir until the coating is uniform. 
5. Assemble the casserole: Evenly distribute the mixture in the baking dish that has been prepared. Add the remaining 1/2 cup of Swiss cheese on top. 
6. Add the topping (optional): If using breadcrumbs, mix panko with melted butter and sprinkle over the casserole for a crispy finish.
7. Bake: Place the casserole in the oven and bake for 25-30 minutes until the cheese is bubbly and the top is golden brown.
8. Garnish and serve: Before serving, take it out of the oven, sprinkle it with fresh parsley, and let it rest for five minutes.

What’s in Chicken Cordon Bleu Casserole?

The beauty of this casserole lies in its simple yet flavorful ingredients, inspired by the traditional chicken cordon bleu. Among the essential elements are: 

• Chicken: Provides the protein base, typically cooked and shredded or cubed.
• Ham: Adds a smoky, salty contrast to the chicken.
• Swiss cheese: Delivers the signature nutty, melty texture.
• Creamy sauce: A blend of cream of chicken soup, sour cream, and milk creates a rich, velvety base.
• Pasta: Egg noodles or short pasta like penne add heartiness and soak up the sauce.
• Seasonings: Dijon mustard, garlic, and onion powder enhance the flavor profile.
• Optional topping: Panko breadcrumbs mixed with butter create a crunchy, golden crust.

These ingredients work together to mimic the layered flavors of the classic dish while making it easier to prepare.

Can You Use Rotisserie Chicken in Cordon Bleu Casserole?

Absolutely! Rotisserie chicken is a fantastic time-saver for this recipe. It’s already cooked, seasoned, and tender, making prep a breeze. Simply shred or cube about 4 cups of rotisserie chicken and add it to the casserole mixture. Using rotisserie chicken also adds extra flavor from its seasoning, enhancing the overall dish. If you’re watching sodium, opt for a low-sodium rotisserie chicken to balance the saltiness of the ham and cheese.

What Cheese Is Best for Chicken Cordon Bleu?

Traditional chicken cordon bleu calls for Swiss cheese, and it’s the star of this casserole, too. Swiss offers a mild, nutty flavor and excellent melting qualities. For a more complex taste, consider these options:

• Gruyère: A close cousin to Swiss, Gruyère adds a slightly sharper, earthier flavor.
• Mozzarella: For a milder, stretchy texture, mix mozzarella with Swiss.
• Provolone: Adds a smoky undertone that pairs well with ham.

For the best results, use freshly shredded cheese, as pre-shredded varieties often contain anti-caking agents that affect melting. A blend of Swiss and Gruyère is highly recommended for a restaurant-quality casserole.

Can You Make Chicken Cordon Bleu Casserole Ahead of Time?

Yes, this casserole is perfect for meal prep! It can be put together up to 24 hours ahead of time. Here’s how: 

1. Prepare the casserole as directed, but don’t add the breadcrumb topping (if using).
2. Refrigerate after tightly covering with foil or plastic wrap.
3. When ready to bake, let it sit at room temperature for 20 minutes, add the breadcrumb topping, and bake as directed, adding 5-10 minutes to the cooking time if it’s still cold.

This make-ahead option is ideal for busy weeknights or entertaining guests.

Do You Need Breadcrumbs for Cordon Bleu Casserole?

Breadcrumbs are optional, but they add a delightful crisp texture to the casserole. Panko breadcrumbs, mixed with melted butter, create a light, crunchy topping that contrasts with the creamy interior. If you prefer a softer texture or want a gluten-free version, you can skip the breadcrumbs entirely—the casserole is still delicious with just the cheesy top. For a low-carb alternative, try crushed pork rinds or almond flour mixed with butter.

How Long to Bake Chicken Cordon Bleu Casserole?

Bake the casserole at 350°F (175°C) for 25-30 minutes, or until the cheese is melted, bubbly, and slightly golden. If you’re using a refrigerated make-ahead casserole, increase the baking time to 35-40 minutes to ensure it’s heated through. To check doneness, insert a knife into the center; it should come out hot. If the top browns too quickly, cover loosely with foil.

Can You Freeze Cordon Bleu Casserole?

Yes, this casserole freezes beautifully! Here’s how to do it:

• Before baking: Assemble the casserole (without the breadcrumb topping), wrap tightly in plastic wrap and foil, and freeze for up to 3 months. Thaw in the fridge overnight, add breadcrumbs, and bake as directed.
• After baking: Cool completely, portion into airtight containers, and freeze for up to 2 months. Reheat individual portions in the microwave or oven.

Label with the date to keep track, and avoid freezing with the breadcrumb topping, as it can become soggy.

What Sides Go with Chicken Cordon Bleu Casserole?

This rich, cheesy casserole pairs well with light, fresh sides to balance its flavors. Here are some ideas:

• Green vegetables: Steamed broccoli, roasted asparagus, or a crisp green salad with vinaigrette.
• Starchy sides: Garlic bread, mashed potatoes, or roasted sweet potatoes for extra comfort.
• Low-carb options: Sautéed zucchini, cauliflower rice, or a cucumber-tomato salad.
• Fruit: A simple fruit salad adds a refreshing contrast.

For a complete meal, serve with a glass of white wine, like Chardonnay, to complement the creamy sauce and cheese.

How to Reheat Chicken Cordon Bleu Casserole?

To reheat leftovers while keeping the casserole creamy and delicious:

• Oven: Preheat to 350°F, cover with foil, and bake for 15-20 minutes until warmed through. Remove foil for the last 5 minutes to crisp the top.
• Microwave: Place a portion on a microwave-safe plate, cover loosely, and heat in 1-minute intervals, stirring if possible, until hot.
• Add moisture: If the casserole seems dry, drizzle with a splash of milk or chicken broth before reheating.

Store leftovers in an airtight container in the fridge for up to 3-4 days.
