Take this Chicken Cordon Bleu sauce. Whenever my dad made this dish growing up, I knew it was going to be a special night.

While the crispy and salty chicken stuffed with ham slices and Swiss cheese was fabulous…it was THIS sauce that made it.

Try this easy Chicken Cordon Bleu recipe next time you’re craving a fancy but still relatively easy dinner and lather some of this creamy sauce on top.

Butter, flour, herbs, mustard, and cheese are the ingredients for the sauce.

Ingredients

The simple ingredients you need to make this Cordon Bleu sauce recipe include:

  • Butter. Opt for unsalted, or be sure to adjust the amount of salt you add later. You can use a dairy-free version if you’d like.
  • Garlic. Minced garlic is sautéed with butter to make a rich base.
  • Dijon mustard. While yellow will work, the flavor will NOT be the same, so stick with Dijon.
  • Milk. You can use either regular dairy or a plant-based alternative.
  • Flour. Both all-purpose and a gluten-free 1-to-1 blend will work perfectly.
  • Parmesan cheese. Shredded or grated work, and fresh is best.
  • Thyme. This fresh herb adds so much flavor to the sauce. You can sub with dried if you need to.

How to Make Chicken Cordon Bleu Sauce

These are the steps to follow to make this creamy Dijon sauce recipe:

Sauté the Butter and Garlic

Heat a small saucepan over medium heat. Drop in 1 tablespoon of butter and let it melt.

Add in minced garlic and continue cooking for another 30 seconds, until it’s aromatic.

Butter and garlic are sauteed together.

Add the Flour and Milk

Quickly sprinkle 1 tablespoon of flour over the butter and garlic. Use a whisk to stir it in so it’s well incorporated.

Slowly add the milk into the flour-butter mixture. Do this a couple of tablespoons at a time, whisking well and allowing it to thicken after each addition.

Give it Flavor

Once the sauce is thick and creamy, pour in the cheese, mustard, salt, pepper, and thyme. Stir well until it is smooth.
