Baked Chicken Cordon Bleu with Dijon
Not rated yet. Be the first.
Thin chicken folded around ham and Gruyère, with a buttery panko crust. Nothing is fried, so you get to sit down with the family when the first knife goes through and the cheese gives way.
The short version
Pound the breasts thin, fold them around Dijon, ham and Gruyère, coat in flour, egg and butter-toasted panko, then bake at 375°F for 25 to 30 minutes until the center hits 165°F. Don't skip toasting the panko; it's what browns the crust without frying.
What makes ours better
the tricks Nonna pretends she never taught me
-
Toast the panko in butter first. Baking never browns a dry crumb the way a skillet does. Two minutes in a pan with butter gives the crust its golden color before the chicken even goes in the oven.
-
Spread Dijon inside. A thin smear on the chicken cuts through the ham and cheese, so every bite tastes bright instead of just rich.
-
Use Gruyère, thin-sliced, kept off the edges. Gruyère melts smoothly and has more flavor than mild Swiss. Leaving a border and pressing the edges shut keeps it from leaking onto the pan.
-
Bake on a rack. Air circulating underneath keeps the bottom crisp instead of steaming against the pan.

Steps
deep breath. you’ve got this.
-
Heat the oven, set up the pan
Heat the oven to 375°F with a rack in the middle. Set a wire rack in a rimmed baking sheet and coat the rack lightly with oil or cooking spray.
-
Toast the panko
Melt the butter in a large skillet over medium heat. Add the panko and the ½ teaspoon salt and stir for 2 to 3 minutes, until the crumbs turn light golden and smell toasty. Tip them into a shallow dish, stir in the parsley, and let them cool.
Pull them while they're still light. They darken more in the oven.
About 3 min. Cook mode has a timer for this step.
-
Pound the chicken thin
Put each breast between two sheets of plastic wrap or parchment. Pound with a rolling pin or heavy pan until about ⅜ inch thick, working from the center out. Season both sides with the salt and pepper.
-
Fill and fold
Lay a breast smooth side down. Spread 1 teaspoon Dijon over one half, leaving a ½-inch border. Top with a slice of ham, then a slice of Gruyère set in from the edges. Fold the chicken over and press the edges firmly together to seal. Repeat with the rest.
If an edge won't stay shut, pin it with a toothpick and pull it out before serving.
-
Bread the packets
Set up three dishes in a row. Put the flour in the first, the eggs beaten with the water in the second, and the toasted panko in the third. Press each packet into the flour, shake off the extra, dip it in the egg, then press it firmly into the panko on both sides. Set each on the rack.
-
Bake
Bake for 25 to 30 minutes, until the crust is deep golden and an instant-read thermometer slid into the thickest part reads 165°F. Let the chicken rest 5 minutes before cutting so the cheese stays inside.
Check the temperature before you trust the color. Thick breasts can need the full 30 minutes.
About 25 min. Cook mode has a timer for this step.
-
Make the sauce (optional)
While the chicken rests, simmer the cream in a small saucepan over medium heat for 3 to 4 minutes, until it coats the back of a spoon. Whisk in the Dijon and a pinch of salt. Spoon it around the chicken, not over the crust.
About 4 min. Cook mode has a timer for this step.
Good to know
the stuff I’d tell you over the phone
- Breasts vary a lot in size. If yours are very large, slice each in half horizontally and pound the halves, then use two pieces per packet.
- Make the filled packets up to a day ahead and keep them wrapped in the fridge, but wait to bread them until just before baking so the crust stays crisp.
- Swap the ham for thinly sliced cooked turkey or leave it out for a cheese-only version.
- Storage. Fridge in an airtight container, 3 days. Reheat on a rack at 350°F for 15 minutes so the crust crisps again; a microwave will soften it.
Questions, answered
the questions my cousins text me
Can I make chicken cordon bleu ahead of time?
Fill and fold the chicken up to a day ahead and refrigerate it. Bread it just before baking, because a crumb coating that sits turns soggy. You can also bread and freeze the packets on a tray, then bake from frozen for about 10 minutes longer.
How do I keep the cheese from leaking out?
Leave a ½-inch border around the filling, press the edges together firmly, and use thin slices. A toothpick holds a stubborn edge shut. A little leakage is normal and tastes fine.
What temperature is chicken cordon bleu done?
165°F in the thickest part. Slide the thermometer in from the side, past the filling, and check the chicken itself.
Can I use chicken thighs?
Yes. Use boneless skinless thighs, pound them to an even thickness, and expect a slightly longer bake. Go by the thermometer.
Can I make it without breadcrumbs?
Crushed pork rinds or crushed cornflakes work. Toast cornflakes with the butter the same way. Skip the flour and egg if you use pork rinds, and press them straight onto the chicken after brushing it with mustard.

Made it? Tell me how it went, and who went back for seconds when they thought nobody was looking.
Made it?
be honest. I can take it. probably.
