Why I Love This Recipe

From the time I was young, I’ve loved chicken cordon bleu. Any restaurant that served it on their menu was an instant win for me. (That and a good fish and chips!) There was nothing better than cutting into the breaded chicken breast and having the oozy Swiss cheese seep out onto my plate. It was kind of like an adult version of a chicken tender 🙂

As I’ve grown up, and my palette has matured, I’ve really come to understand and appreciate why chicken cordon bleu is traditionally served with a creamy mustard sauce. The balance the chicken cordon bleu sauce provides is amazing. I can’t eat it any other way now as an adult! In fact, my favorite Chicken Cordon Bleu Casserole also includes a mustard base sauce over the top!

What is Chicken Cordon Bleu Sauce

Chicken cordon bleu sauce is the traditional creamy topping that comes from the classic French dish. It is a blend of flavors and textures and serves as the perfect companion to this beloved dish. The fresh Parmesan cheese adds a natural saltiness that is balanced out by the mustard, which adds interest to your palette. There are some recipes that leave out the mustard but the traditional French recipe has either dijon or spicy brown mustard in it.

How to Make Chicken Cordon Bleu Sauce

If you have just a few minutes and basic ingredients, you can make this classic sauce at home!

Time needed: 10 minutes

How to Make Chicken Cordon Bleu Sauce

  1. Create a roux in a shallow skillet

    Combining the salted butter and flour, then allowing it to cook for a few minutes is how you create a roux. That cooked fat and flour mixture is what thickens the cordon bleu sauce. Be sure to cook it after it comes together to eliminate the “starchy” flavor and texture of the finished sauce.

  2. Add the milk and allow the sauce to thicken

    The most important part of this step is to whisk continually. Both when you add the milk to the roux, as well as when the sauce cooks and thickens. Doing so will keep the sauce from being lumpy.

  3. At the end, add the mustard, cheese, and seasonings

    Once the flavorings have been added to the sauce, there is no need to continue to cook it. It is ready to go over the top of your chicken cordon bleu.

Recipe FAQs

What is cordon bleu sauce made of?

A classic chicken cordon bleu sauce is made with a roux of butter and flour that is cooked until it begins to brown a bit. Then you add some whole milk, dijon mustard, Parmesan cheese, kosher salt, and black pepper. There are other variations of the sauce but this is the most traditional version.

How do you serve cordon bleu?

How you serve chicken cordon bleu is completely up to you. You can certainly serve it as whole breasts, with the sauce on the side, and allow your guests to cut into it. This allows them to experience the oozy Swiss cheese for themselves! Or, once it has rested after being baked you can cut it into 1/2-inch slices and drizzle the sauce over the top. This presentation method allows your guests to see the beautiful insides of the cordon bleu from the start.

Can I make chicken cordon bleu sauce without the mustard?

While the classic chicken cordon bleu sauce always uses mustard as the base of the recipe, I know it isn’t everyone’s favorite flavor. So yes, you can leave out the mustard completely from the sauce. However, you will need to compensate with additional fresh Parmesan cheese so the sauce isn’t too bland.

How to store and reheat chicken cordon bleu sauce

To store any leftover chicken cordon bleu sauce, simply place it in an airtight container in the refrigerator for up to 5 days. When it comes time to reheat it, you can do so in the microwave or stovetop. You might need to add a few dashes of milk to thin it back out once it is warmed.

Can I make this sauce healthier by using skim milk?

Yes, you can use skim milk to save a bit of calories and fat in this recipe but your end result will be a bit different. The sauce will be thinner and not quite as flavorful as if you used 2% or whole milk. If you do use skim milk, try adding a bit more freshly grated Parmesan cheese to help compensate for non-fat milk.

What to Serve with Chicken Cordon Bleu and Sauce

No matter if you are making my easy chicken cordon bleu, or my cordon bleu casserole, any of these side dishes will pair well with them. They are fresh and light, which balances well with the rich and creamy cordon bleu.

If it is a Swiss cheese sauce why are you using parmesan?

Hi Marla, sorry for any confusion. The sauce is parmesan based, but the chicken cordon bleu is filled with Swiss cheese. So you get a combination of Swiss inside the chicken and then parmesan in the sauce on top.
