Easy Baked Chicken Cordon Bleu With Dijon Sauce

Golden panko, tender chicken, and melted Swiss cheese make this dinner feel special without requiring a frying pan. This Easy Baked Chicken Cordon Bleu uses a simple pocket-cutting method, so you won’t need to pound and roll the chicken breasts.

Thin deli ham surrounds the cheese inside each pocket, while a mayonnaise-Dijon coating helps the toasted crumbs cling to the surface. A warm Parmesan-Dijon cream sauce adds a smooth, tangy finish. The complete meal takes about 45 minutes and makes two generous servings.

Why You’ll Love This Recipe

• Ready in approximately 45 minutes, including preparation and baking.
• Uses an easier pocket method instead of pounding and rolling chicken.
• Pre-toasted panko creates a more evenly golden, crisp coating.
• Swiss cheese melts inside the ham-lined pocket with less leakage.
• Makes two generous portions with plenty of creamy Dijon sauce.

Ingredients

For the Chicken Cordon Bleu

• 2 small boneless, skinless chicken breasts, 6–7 oz each (180–210 g each), completely thawed if previously frozen
• Salt, to taste
• Ground black pepper, to taste
• 4 slices Swiss cheese
• 4–6 thin slices cooked deli ham, approximately 2.5 oz (75 g) total
• ½ cup panko breadcrumbs, approximately 30 g
• Oil spray, as needed
• 3 Tbsp mayonnaise, approximately 45 g
• 1½ Tbsp Dijon mustard, approximately 22 g

Use small chicken breasts that are thick enough to hold a pocket. Thin cutlets suit rolled or layered recipes but can’t contain the filling required for this method. Thin refrigerated deli ham is also easier to arrange around the cheese than thick-cut ham.

For the Dijon Cream Sauce

• 1½ Tbsp unsalted butter, approximately 21 g
• 1½ Tbsp all-purpose flour, approximately 12 g
• 1¼ cups full-fat milk, 300 ml
• 2 Tbsp Dijon mustard, approximately 30 g
• 3 Tbsp finely grated Parmesan cheese, approximately 15 g
• Salt, to taste
• Ground black pepper, to taste

Full-fat milk gives the sauce its intended richness and consistency. Keep in mind that the sauce will continue to thicken as it stands.

How to Make This Recipe

Step 1: Toast the Panko and Prepare the Filling

Preheat a conventional oven to 390°F (200°C), or a fan oven to 350°F (180°C). Spread the panko on a rimmed 13-by-18-inch metal baking sheet, mist lightly with oil, and bake for about 3 minutes until light golden. Immediately transfer it to a bowl so the hot pan doesn’t overbrown it. Meanwhile, fold two Swiss slices for each chicken breast and arrange the thin ham around the cheese.

Step 2: Stuff and Coat the Chicken

Cut a deep pocket into the side of each chicken breast without slicing through the opposite edge. Insert one ham-and-cheese bundle into each pocket, close with approximately two toothpicks, and season with salt and black pepper. Combine the mayonnaise and 1½ Tbsp Dijon mustard, spread it over the tops and sides, then press on the toasted panko and mist lightly with oil.

Pro Tip: Keep the pocket opening fairly narrow and make sure the ham surrounds the cheese. Cutting completely through the chicken or leaving the pocket open can allow more cheese to escape.

Step 3: Bake the Chicken

Place the coated breasts on the same baking sheet and bake for 25–30 minutes, checking the smaller piece first. The panko should look evenly golden, dry, and crisp. Check the thickest chicken portion and the filled center separately with an instant-read thermometer; both must reach 165°F (74°C).

Step 4: Make the Sauce and Serve

Meanwhile, melt the butter in a small saucepan over medium heat. Stir in the flour and cook for 1 minute, then whisk in half the milk until smooth. Add the remaining milk, 2 Tbsp Dijon, and Parmesan; whisk for about 3 minutes until thickened but pourable, then season with salt and pepper. Remove every toothpick and serve the chicken with the warm sauce.

Pro Tip: The sauce thickens as it stands, so prepare it while the chicken bakes and keep it warm until serving.

Expert Tips for Better Results

• Thaw frozen raw chicken completely in the refrigerator before cutting it. Partially frozen breasts may cook unevenly.
• Choose breasts within the approved 6–7 oz range. Larger pieces may not finish within the stated baking window.
• Keep the pocket opening as narrow as practical while making enough room for the filling.
• Fold the thin ham around the Swiss cheese before inserting it. This helps contain the melting cheese.
• Measure temperature in the thickest chicken portion and the center filling; color alone isn’t a dependable safety check.
• Check the smaller breast first if the two pieces aren’t identical in size.

Serving Suggestions

• Serve with steamed broccoli for a fresh vegetable that balances the creamy Dijon sauce.
• Add roasted asparagus for a simple side with lightly crisp edges.
• Spoon the sauce beside mashed potatoes so they can catch every savory drop.
• Pair the chicken with lemon rice for a bright contrast to the ham and Swiss cheese.
• Choose a crisp green salad with a light dressing to offset the rich filling and sauce.

Storage and Reheating

Refrigerate the chicken and Dijon sauce in separate airtight containers within two hours of cooking. Keeping them separate protects the panko coating from absorbing the sauce and becoming soggy. Store both in the refrigerator at 40°F (4°C) or below for 3–4 days.

For longer storage, freeze the completely cooled chicken without the sauce in an airtight freezer-safe container for up to 3 months. Thaw it overnight in the refrigerator. Freezing the dairy-based sauce isn’t recommended because it may separate after thawing.

Reheat thawed chicken in a baking dish at 350°F (175°C) until its center reaches 165°F (74°C). Cover it loosely for most of reheating to limit moisture loss, then uncover it briefly if the panko needs to become crisp again. The exact reheating time will depend on the chicken’s size and starting temperature.

Warm the sauce separately over low heat, whisking gently. If necessary, whisk in a small amount of milk to return it to a pourable consistency. Microwave reheating can soften the panko, so the oven is the better choice when preserving the coating matters.
