Grilled Chicken Cordon Bleu Sandwich Recipe tastes like a fancy bistro meal in handheld form, with smoky grilled chicken, salty ham, gooey Swiss, and a tangy Dijon sauce on toasted bread. It works perfectly for busy weeknights or casual weekend cookouts, and you can get it on the table in about 35–40 minutes. I first made a version of this in a tiny apartment with a grill pan and a lot of optimism, and it still feels like comfort food with a little swagger.
Why Make This Grilled Chicken Cordon Bleu Sandwich Recipe at Home
You control everything at home, from how melty the cheese gets to how crispy the bread toasts. You also skip the mystery sauces and use real ingredients that actually taste like something.
You also save money, especially if you already keep sliced ham and cheese in the fridge. Leftover grilled chicken turns into a seriously good sandwich instead of a sad container in the back of the fridge.

Ingredients You Need
Chicken and marinade
- 2 large boneless skinless chicken breasts, butterflied and pounded to 1/2 inch thick
- 2 tablespoons olive oil
- 1 tablespoon lemon juice or apple cider vinegar
- 2 teaspoons Dijon mustard
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon kosher salt
- 1/2 teaspoon black pepper
- 1/2 teaspoon smoked paprika or sweet paprika
Use any neutral oil if you run out of olive oil. I like smoked paprika for a grilled flavor boost, especially on an indoor grill pan.
Sandwich fixings
- 4 sturdy sandwich rolls, brioche buns, ciabatta, or thick sliced sourdough
- 8 slices thin deli ham (Black Forest or honey ham both work)
- 4 slices Swiss cheese (Gruyère or provolone also work)
- 2 tablespoons softened butter or mayonnaise, for toasting the bread
- 4 large lettuce leaves (romaine or butter lettuce)
- 1 large tomato, sliced
- 4–6 dill pickle slices, optional
Use whatever ham you already keep on hand, just slice it thin so it warms quickly. Pre sliced Swiss from brands like Sargento or Tillamook melts nicely and saves time.
Creamy Dijon sauce
- 1/4 cup mayonnaise
- 1 tablespoon Dijon mustard
- 1 teaspoon yellow mustard or spicy brown mustard
- 1 teaspoon honey or maple syrup
- 1 teaspoon lemon juice
- Pinch of salt and black pepper
You can use light mayo or Greek yogurt for a lighter version. I like half mayo and half Greek yogurt for a tangy, creamy sauce that still tastes rich.
Equipment
- Outdoor grill, grill pan, or cast iron skillet
- Meat mallet or rolling pin to pound chicken
- Small bowl and whisk for sauce
- Tongs
- Instant read thermometer, helpful but optional
- Cutting board and sharp knife
Tips & Mistakes
- Pound the chicken to an even thickness so it cooks evenly and stays juicy.
- Dry the chicken with paper towels before marinating so the seasoning sticks.
- Do not skip the oil in the marinade, since it keeps the chicken from drying out on the grill.
- Preheat the grill or pan until it feels hot, or the chicken will stick and steam instead of sear.
- Oil the grates lightly or brush the chicken with a bit of oil to prevent sticking.
- Avoid overcooking the chicken; pull it at 165°F internal temperature for the best texture.
- Toast the bread lightly so it holds the fillings without turning tough or scratchy.
- Layer cheese directly on the hot chicken so it melts instead of sliding around.
- Keep the sauce amount moderate, or the sandwich will slide apart and feel soggy.
- Rest the grilled chicken for 5 minutes before slicing so the juices stay inside.
How to Make Grilled Chicken Cordon Bleu Sandwich Recipe
Prep the chicken
Slice each chicken breast horizontally to butterfly it, then open it like a book. Place the chicken between two sheets of parchment or plastic wrap and pound it to about 1/2 inch thick. Trim any ragged edges so it cooks evenly.
Pat the chicken dry. In a bowl, whisk olive oil, lemon juice, Dijon, garlic powder, onion powder, salt, pepper, and paprika. Add the chicken and coat it well, then let it sit at room temperature for 15–20 minutes while you prep everything else.
Mix the Dijon sauce
In a small bowl, stir together mayonnaise, Dijon, yellow or spicy mustard, honey, lemon juice, salt, and pepper. Taste and adjust the tang or sweetness to your liking. Chill the sauce in the fridge while you grill the chicken.
Grill the chicken
Preheat your grill or grill pan over medium high heat. Lightly oil the grates or brush the chicken with a bit of oil.
Place the chicken on the hot grill and cook about 4–6 minutes per side, depending on thickness. Flip once, and cook until the internal temperature reaches 165°F and the juices run clear.
Move the chicken to a plate and cover it loosely with foil. Let it rest for 5 minutes so it stays juicy when you slice it.
Toast the bread and warm the ham
Slice the rolls if needed. Spread the cut sides lightly with softened butter or mayonnaise.
Place the bread cut side down on the grill or in a skillet over medium heat. Toast until golden and crisp around the edges, then pull it off the heat.
Add the ham slices to the grill or pan in small piles and warm them for 30–60 seconds per side. You just want a little color and heat, not crispy ham chips.
Build the sandwiches
Slice the rested grilled chicken into thick strips that fit your bread. On the bottom half of each toasted roll, spread a spoonful of the creamy Dijon sauce.
Layer sliced grilled chicken on top, then add warm ham slices. Place a slice of Swiss cheese over the ham.
Set the open sandwiches back on the grill or under a broiler for 1–2 minutes, just until the cheese melts. Keep an eye on them so the bread does not burn.
Pull the sandwiches off the heat. Add lettuce, tomato slices, and pickles if you like. Spread a little more sauce on the top half of the roll, cap the sandwich, and serve hot.
Variations I've Tried
I sometimes swap the Swiss for sharp white cheddar, which gives the sandwich a stronger, nuttier flavor. Provolone also works nicely when I want a milder, super melty cheese.
Thin grilled turkey cutlets stand in for chicken when I need to use what I already have. Smoked turkey with ham and Swiss tastes a bit like a club sandwich with a French accent.
I also enjoy a spicy version with pepper jack cheese and a teaspoon of hot sauce whisked into the Dijon sauce. Jalapeño slices add a nice kick if you like heat.
For a lighter take, I skip the top bun and serve the grilled chicken cordon bleu stack over a bed of greens with extra sauce as dressing. It still feels indulgent but sits lighter.
How to Serve Grilled Chicken Cordon Bleu Sandwich Recipe
Serve this grilled chicken cordon bleu sandwich hot, while the cheese still stretches when you bite into it. I like it with a simple green salad, kettle chips, or roasted potato wedges.
You can also add a side of crunchy coleslaw, fruit salad, or sliced cucumbers with a little salt and lime. Pair it with iced tea, lemonade, or sparkling water with citrus for a fresh, family friendly meal.
How to store
- Fridge, chicken and ham: Store leftover grilled chicken and ham in an airtight container in the fridge for up to 3 days.
- Fridge, assembled sandwiches: Keep assembled sandwiches wrapped tightly in foil in the fridge for up to 1 day, and reheat before serving for best texture.
- Freezer, chicken only: Freeze cooked, cooled grilled chicken in a freezer bag for up to 2 months, with parchment between pieces to prevent sticking.
- Reheating chicken: Reheat chicken gently in a covered skillet over medium low heat with a splash of water, or in a 325°F oven for 8–10 minutes until hot.
- Reheating assembled sandwiches: Wrap the sandwich in foil and warm it in a 325°F oven or toaster oven for 10–12 minutes until the cheese melts and the center heats through.
- Bread and sauce: Store bread at room temperature in a sealed bag and keep the Dijon sauce in the fridge for up to 4 days, stirring before each use.
