How long to cook chicken cordon bleu at 400

Chicken Cordon Bleu night made me giddy growing up. My favorite meat (chicken) pounded thin and wrapped around my other favorite meat (ham) and melty cheese, then breaded and deep-fried? What’s for a kid (and any honest adult) not to love?!

How long to cook chicken cordon bleu at 400

Let me clarify: we were baking store bought cordon bleu.

My mom had neither the patience nor the motivation for the kind of painstaking, oily mess it would take to fry chicken cordon bleu at home.

Neither do I.

This healthy baked chicken cordon bleu, however?

It is EASY to make, doesn’t require a deep fryer, and it still has that unstoppably appealing, breading-on-chicken-on-ham-on-cheese situation.

Why I Love Cordon Bleu

This oven baked chicken cordon bleu gave both myself and Ben the nostalgic feels, except that (as Ben so eloquently put it) “it tastes a thousand times better than the frozen stuff we had growing up.”

  • The chicken is juicy, the ham savory, the cheese melty and satisfying, and the golden, crisp breadcrumb exterior adds the exclamation point.
  • In other words, it tastes amazing.

History of Chicken Cordon Bleu

Chicken cordon bleu is believed to be the product of tweaking a similar recipe, veal Kiev. Sometime between veal Kiev’s arrival on the scene in Paris in the 1840s and the arrival of chicken cordon bleu in North America in the 1960s, the adaptation we know today was created.

How to Cook Chicken Cordon Bleu

It takes a few minutes to set up your work station, but once you do, this easy cordon bleu comes together rather quickly.

In addition to being scrumptious straight out of the oven, we were delighted with how well the leftovers were reheated.

  • Like this Spinach Stuffed Chicken Breast, the interior filling insulates the meat and keeps it juicy, even the next day.
  • Unlike this Baked Chicken Breast, you don’t need to brine the meat first to make your chicken cordon bleu juicy.

The Ingredients

  • Chicken Breast. Tender, juicy chicken breast is a delicious vessel for our cheesy ham filling. It’s flavorful while being a lean source of protein.
  • Breadcrumbs. A blend of regular breadcrumbs and Panko breadcrumbs creates the ideal crispy, golden crust. I opted to use the whole wheat version of both types, but you can use regular if you prefer.
  • Parmesan. Adds a salty, cheesy element to the breadcrumb mixture.
  • Spices. Garlic powder and onion powder are the perfect flavor additions to the breadcrumb mixture.
  • Eggs. Helps the breadcrumbs stick to the chicken breasts.
  • Deli Ham. Ham is a scrumptious, integral part of the chicken cordon bleu stuffing. It’s salty, smoky, and pairs wonderfully with the cheese.

Tip!

Rather than purchasing pre-sliced, packaged ham, which is usually thicker cut and not the best quality or flavor, purchase it directly from the deli counter and ask for it to be sliced very thin.

  • Gruyere. Rich, creamy, and nutty, Gruyere works beautifully for stuffing the chicken.

Substitution Tip!

Swiss or white cheddar would also work well for stuffing the chicken in this recipe.

  • Baking Dish. A 9×13-inch dish is ideal for this recipe.

Frequently Asked Questions

How Do You Know When Chicken Cordon Bleu is Done?

To tell when chicken cordon bleu is done, use an instant read thermometer inserted at the thickest part to check the meat for doneness. Chicken is considered cooked at 165 degrees F. I typically remove the meat at 155 degrees F, as its temperature will continue to rise as it rests.

Can I Make Chicken Cordon Bleu with Frozen Chicken?

Yes, you can use frozen chicken breasts to make this chicken cordon bleu, but you’ll need to thaw the chicken completely first.

Can I Make this Chicken Cordon Bleu in the Air Fryer?

Since this recipe wasn’t designed for the air fryer, I can’t say for certain whether or not it would turn out, but I do think you can have success. If you decide to experiment with it, I’d love to hear how it goes! For guidance, check out my Air Fryer Fried Chicken Breast and Air Fryer Chicken Breast.

  • 1/2 cup breadcrumbs whole wheat if available
  • 1/4 cup Panko breadcrumbs whole wheat if available
  • 1/4 cup grated Parmesan cheese
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/2 teaspoon kosher salt
  • 1/2 teaspoon black pepper
  • 2 large eggs
  • 4 small/medium boneless, skinless chicken breasts about 8 to 10 ounces each
  • 4 thin slices deli ham a scant .25 pounds
  • 3 ounces freshly shredded Gruyere Swiss, or white cheddar cheese (about 3/4 cup)
  • 3 tablespoons unsalted butter melted


  • Preheat your oven to 375 degrees F. Generously coat a 9×13-inch baking dish with nonstick spray. In a wide, shallow bowl (a pie dish works well), stir together the breadcrumbs, Panko, Parmesan, garlic powder, onion powder, salt, and pepper.

  • In a separate wide, shallow dish, beat the eggs.

  • Working one at a time, place a chicken breast on the cutting board with the presentation (smooth) side down. To keep things tidy, cover with a large piece of plastic wrap. With a mallet or rolling pin, gently pound the chicken breasts until they are each 1/4-inch thick (it will seem very thin, but will be easy to roll this way. Be careful not to hit too vigorously for as the meat becomes thinner, it may tear).

  • Top each chicken breast with 1 slice of ham and 3/4 ounce (3 tablespoons) cheese.
