Easy Chicken Cordon Bleu Pasta Bake (Creamy & Cheesy)

Chicken cordon bleu is a restaurant classic: tender chicken, salty ham, and melty Swiss cheese, all wrapped in a crispy golden crust. This pasta bake gives you every one of those flavors in an easy casserole, with no pounding, rolling, or breading of individual cutlets. Penne is tossed in a creamy Dijon Swiss cheese sauce with chicken and ham, then topped with more cheese and buttery crunchy panko.

The best part is how simple it is. You can use leftover chicken or a store-bought rotisserie chicken, the sauce comes together in one skillet in about ten minutes, and the oven handles the rest. It is cozy, cheesy, and special enough for company, yet easy enough for a regular Tuesday.

Why You Will Love This Chicken Cordon Bleu Pasta Bake

It is made for busy nights. Rotisserie chicken, deli ham, and a quick white sauce mean there is very little chopping and almost no cleanup. You can even assemble the whole dish ahead of time, keep it in the fridge, and bake it when you are ready to eat.

It tastes like the classic. The sauce is silky and rich with Swiss cheese and a tangy kick of Dijon mustard, while the ham adds a smoky saltiness. Under a crunchy, golden panko topping, every spoonful is creamy, cheesy, and deeply comforting.

What Is Chicken Cordon Bleu?

Cordon bleu means blue ribbon in French, and the dish is traditionally made by stuffing chicken with ham and Swiss cheese, then breading and frying it until golden. The combination is loved because salty ham, nutty Swiss, and tender chicken taste so good together. In this pasta bake, those same flavors are mixed into a creamy sauce, which makes the dish much easier and lets you feed a whole family from one pan.

Ingredients

For the pasta bake

• 12 oz penne pasta
• 3 cups cooked chicken, diced (about 1 rotisserie chicken)
• 8 oz deli ham, diced
• 2 tbsp butter
• 3 garlic cloves, minced
• 1/4 cup all-purpose flour
• 2 cups whole milk
• 1 cup heavy cream
• 2 tbsp Dijon mustard
• 1 1/2 cups shredded Swiss cheese (about 6 oz)
• 1/2 cup grated parmesan
• 1/2 tsp salt, 1/4 tsp black pepper, pinch of nutmeg (optional)

For the topping

• 4 slices Swiss cheese
• 1 cup panko breadcrumbs
• 2 tbsp butter, melted
• 2 tbsp fresh parsley, chopped

Step-by-Step Instructions

Step 1: Prep the oven, pasta, chicken, and ham

Heat the oven to 375°F and grease a 9×13 inch baking dish. Boil the penne in salted water for 2 minutes less than the package says, so it is still firm. Drain and set aside. While the pasta cooks, dice the chicken and ham into small, bite-size cubes so every forkful has both.

Step 2: Make the creamy Dijon Swiss sauce

Melt 2 tablespoons butter in a large, deep skillet over medium heat. Cook the garlic for 30 seconds, then whisk in the flour and cook for 1 minute. Slowly pour in the milk and cream while whisking, and simmer for 4 to 5 minutes until thick enough to coat a spoon. Reduce the heat to low, whisk in the Dijon, then stir in the Swiss and parmesan until smooth. Season with salt, pepper, and nutmeg.

Step 3: Combine everything

Add the drained penne, chicken, and ham to the sauce and stir until every piece is coated. If the mixture looks too thick, stir in a splash of milk. Taste and adjust the seasoning.

Step 4: Assemble and add the topping

Spread the mixture evenly in the baking dish and lay the Swiss cheese slices over the top. Stir the panko with the melted butter and sprinkle it over the cheese in an even layer.

Step 5: Bake until golden and bubbly

Bake uncovered for 20 to 25 minutes, until the sauce is bubbling around the edges and the panko is deep golden. If you want extra color, broil for 1 to 2 minutes, watching closely. Let it rest for 5 minutes so the sauce can set.

Step 6: Serve

Sprinkle with fresh parsley and scoop generous portions onto plates. Serve with a crisp green salad or steamed broccoli to balance the richness.

Approximate Nutrition (Per Serving)

Tips for the Best Pasta Bake

• Undercook the penne by 2 minutes, because it keeps cooking in the oven.
• Shred your own Swiss cheese from a block, since pre-shredded cheese can make the sauce grainy.
• Add the cheese off high heat so the sauce stays smooth.
• Use a rotisserie chicken for the fastest prep, and mix white and dark meat for the juiciest result.
• Pat the ham dry before dicing so it does not release extra liquid into the sauce.
• Toss the panko with melted butter before sprinkling, so it browns evenly and stays crunchy.

Variations to Try

• Crispy cutlet style: Top each serving with a sliced, pan-fried breaded chicken cutlet.
• Broccoli boost: Stir 2 cups of steamed broccoli florets into the pasta.
• Bacon swap: Use crumbled cooked bacon instead of ham for a smoky twist.
• Lighter version: Replace the cream with extra milk and use whole wheat pasta.
• Gluten free: Use gluten-free pasta, a gluten-free flour blend, and gluten-free breadcrumbs.

Common Mistakes to Avoid

• Overcooking the pasta: Soft pasta turns mushy after baking, so always pull it from the water early.
• Boiling the sauce after adding cheese: High heat can make Swiss cheese stringy or grainy, so keep the heat low.
• Skipping the rest time: Resting for 5 minutes lets the sauce thicken so each scoop holds its shape.
• Using cold cream and milk: Let them sit out for 10 minutes so the sauce comes together smoothly.

What to Serve With Chicken Cordon Bleu Pasta Bake

Because the casserole is rich and creamy, pair it with something fresh and light. A crisp green salad with lemon vinaigrette, roasted asparagus, steamed green beans, or garlic roasted broccoli all balance the cheese and cream nicely. A slice of crusty bread is great for scooping up any leftover sauce on the plate, and a sparkling lemonade or iced tea makes the meal feel complete.

Storage and Reheating

Cover leftovers and refrigerate for up to 4 days. To reheat, cover the dish with foil and warm it at 350°F for 15 to 20 minutes, or microwave single portions with a splash of milk to loosen the sauce. To freeze, cool the baked pasta completely, wrap it tightly, and freeze for up to 3 months, then thaw overnight in the fridge. You can also assemble the dish without the topping up to a day ahead, then add the panko and bake just before serving.

Frequently Asked Questions

Can I make chicken cordon bleu pasta bake ahead of time?

Yes. Assemble the dish without the panko topping, cover, and refrigerate for up to 24 hours. Add the buttered panko just before baking, and add 5 to 10 minutes to the baking time since the dish will be cold.

What kind of ham works best?

Thick-sliced deli ham or leftover baked ham both work well. Choose a ham with good flavor, because it seasons the whole dish, and dice it small so it spreads evenly through the pasta.

Can I use a different cheese instead of Swiss?

Yes. Gruyère is a delicious upgrade with a nutty flavor, and provolone or mild white cheddar will also work. Swiss gives the most authentic cordon bleu taste.

Why is my sauce too thin or too thick?

If it is thin, simmer it a few minutes longer before adding the cheese. If it is thick, stir in a splash of milk. The sauce thickens as the pasta absorbs it, so aim for a slightly looser sauce before baking.
