Ingredients You Need
Chicken and Marinade
- 2 large boneless skinless chicken breasts, butterflied and pounded to even thickness
- 2 tablespoons olive oil
- 1 tablespoon Dijon mustard
- 1 tablespoon lemon juice or red wine vinegar
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon kosher salt
- ½ teaspoon black pepper
- ½ teaspoon smoked paprika or sweet paprika
You can use chicken cutlets to skip pounding. Use avocado oil instead of olive oil if you grill over very high heat.
Sandwich Assembly
- 4 sturdy sandwich rolls, brioche buns, ciabatta, or thick sliced sourdough
- 4 teaspoons softened butter or mayo, for toasting bread
- 4 slices deli ham, thin but not paper thin
- 4 slices Swiss cheese or provolone
- 4 leaves romaine or green leaf lettuce
- 1 large tomato, sliced
- 4 slices cooked bacon, optional but delicious
Choose a bread that holds up to grilling and juicy fillings. I like bakery ciabatta or brioche because they toast nicely and resist sogginess.
Dijon Mayo Sauce
- ¼ cup mayonnaise
- 1 tablespoon Dijon mustard
- 1 teaspoon honey or maple syrup
- ½ teaspoon lemon juice
- Pinch of salt and pepper
Use light mayo if you want a lighter sauce. Stone ground mustard works well if you prefer a bit more texture and bite.
Pantry Shortcuts and Brand Notes
- Use pre sliced grilled chicken from the deli section in a pinch, but season it lightly with extra salt and pepper.
- Use pre sliced Swiss from any major brand; I like low moisture slices because they melt evenly.
- Use bottled lemon juice if fresh lemons hide from you in the crisper drawer.
Equipment List
- Grill pan, outdoor grill, or cast iron skillet
- Small bowl for marinade
- Small bowl for Dijon mayo
- Tongs
- Meat thermometer
- Cutting board and sharp knife
Quick Tips & substitutions
- Pound chicken to an even thickness so it cooks quickly and stays juicy.
- Oil the grill grates lightly to prevent sticking and easier cleanup.
- Use turkey slices instead of ham if you avoid pork.
- Swap Swiss with provolone, Havarti, or mozzarella for a milder flavor.
- Use Greek yogurt mixed with a little mayo for a lighter sauce.
- Choose gluten free buns if you need a gluten free option.
- Toast bread only to light golden color so it stays tender inside.
- Slice chicken against the grain if you prefer smaller pieces in the sandwich.
- Add a slice of cooked bacon for extra crunch and smoky flavor.
- Use baby spinach instead of lettuce if you want more nutrients and a softer bite.
How to Make Grilled Chicken Cordon Bleu Sandwich
1: Prep and marinate the chicken
Place the butterflied chicken breasts between two sheets of parchment and pound them to about ½ inch thickness. In a small bowl, whisk olive oil, Dijon mustard, lemon juice, garlic powder, onion powder, salt, pepper, and paprika. Add chicken to the bowl or a zip bag, coat it well, and let it sit for at least 15 minutes at room temperature or up to 4 hours in the fridge.
2: Mix the Dijon mayo
In another small bowl, stir together mayonnaise, Dijon mustard, honey, lemon juice, salt, and pepper. Taste and adjust the tang or sweetness to your liking. Chill the sauce while you grill the chicken so the flavors meld.
3: Grill the chicken
Heat a grill pan or outdoor grill over medium high heat and lightly oil the grates. Place marinated chicken on the hot surface and cook about 4 to 6 minutes per side, depending on thickness, until the internal temperature reaches 165°F. Move the chicken to a plate, tent loosely with foil, and let it rest for 5 minutes so the juices settle.
4: Toast the bread
Slice your rolls or bread if needed. Spread a thin layer of butter or mayo on the cut sides. Place bread cut side down on the grill or in a skillet over medium heat and toast until golden and crisp at the edges.
5: Build the cordon bleu layers
Slice the rested chicken into sandwich sized pieces if needed. Spread Dijon mayo on both sides of each toasted roll. Layer lettuce, tomato slices, grilled chicken, a slice of ham, and a slice of Swiss cheese on each bottom half.
6: Melt the cheese
Place the open sandwiches back on the grill or in the skillet over low heat. Cover the pan with a lid or an upside down metal bowl to trap heat and melt the cheese. Once the cheese turns melty and stretchy, remove from heat and cap each sandwich with the top bun.
Recipe Variations
- Gluten free: Use gluten free buns or sturdy gluten free bread and check labels on ham and mustard.
- Low carb: Skip the bun and serve the grilled chicken, ham, and cheese over a big salad with extra Dijon dressing.
- Extra protein: Add a fried or over easy egg on top of the cheese.
- Extra flavor: Add caramelized onions or sautéed mushrooms between the chicken and cheese.
- Kid friendly: Use mild cheese like mozzarella and go lighter on the Dijon in the sauce.
- Spicy twist: Add sliced jalapeños or a little hot sauce to the Dijon mayo.
Ways to Serve Grilled Chicken Cordon Bleu Sandwich
- Pair with a simple green salad with lemon vinaigrette.
- Serve with baked sweet potato fries or classic oven fries.
- Add a side of crunchy coleslaw for texture contrast.
- Pack in a lunchbox with carrot sticks and apple slices.
- Cut into halves or quarters and serve as party sliders.
Storage Success
Store leftover grilled chicken, ham, and cheese in an airtight container in the fridge for up to 3 days. Keep the bread and Dijon mayo separate so everything stays fresh and avoids sogginess. Reheat the chicken and ham in a skillet over medium heat, then add cheese and cover the pan until it melts. Toast fresh bread, assemble with sauce and veggies, and your leftover Grilled Chicken Cordon Bleu Sandwich Recipe tastes almost like a fresh batch.
