Why Grilled Chicken Cordon Bleu Sandwich Recipe Is Worth It

You get all the flavor of classic chicken cordon bleu without pounding, stuffing, breading, and deep frying. The grill adds a smoky char that plays perfectly with the creamy cheese and salty ham.

This sandwich also works great for feeding a crowd, since you can grill several chicken breasts at once and build a platter of sandwiches. Cleanup stays simple, and you only need a handful of pantry staples to pull it off.

Ingredients You Need

Chicken and marinade

2 large boneless skinless chicken breasts, sliced horizontally into 4 cutlets
2 tablespoons olive oil
1 tablespoon Dijon mustard
1 tablespoon lemon juice or apple cider vinegar
2 cloves garlic, minced or grated
1 teaspoon kosher salt
½ teaspoon black pepper
½ teaspoon smoked paprika or regular paprika
½ teaspoon dried Italian seasoning or dried thyme

I like Dijon from Maille or Grey Poupon for consistent flavor. You can swap olive oil with avocado oil if that fits your pantry better.

Sandwich build

4 slices deli ham, thin but not see through
4 slices Swiss cheese, or provolone if you prefer milder flavor
4 sturdy sandwich rolls, brioche buns, ciabatta, or pretzel buns
2 tablespoons butter or olive oil, for toasting buns

Choose rolls that hold up to juicy chicken. Soft hamburger buns tend to collapse, so I reach for brioche or ciabatta.

Sauce and toppings

¼ cup mayonnaise
1 tablespoon Dijon mustard
1 teaspoon honey or maple syrup
1 teaspoon lemon juice
Pinch of salt and pepper
4 lettuce leaves, romaine or butter lettuce
1 large tomato, sliced
4–6 pickle slices, optional but tasty

You can use light mayo or Greek yogurt for a lighter spread. I often mix half mayo and half yogurt to keep it creamy but not too heavy.

Equipment

Grill (gas, charcoal, or grill pan on the stove)
Tongs
Small mixing bowl and whisk
Cutting board and sharp knife
Instant read thermometer, strongly recommended
Basting brush, optional but handy

Quick Tips & substitutions

Pound thicker chicken pieces slightly so they cook evenly and stay juicy.
Pat chicken dry before marinating so the seasoning sticks better.
Use rotisserie chicken slices if you feel short on time; just warm them on the grill or in a skillet.
Swap Swiss with provolone, Havarti, or mozzarella if you dislike strong Swiss flavor.
Use turkey slices instead of ham if you prefer lower sodium or do not eat pork.
Toast the buns on the grill for extra flavor and to keep them from getting soggy.
Brush the chicken with a little extra Dijon during grilling for a stronger cordon bleu vibe.
Use gluten free buns if you need a gluten free grilled chicken cordon bleu sandwich.
Grill extra chicken and store it for salads, wraps, or another round of sandwiches.

How to Make Grilled Chicken Cordon Bleu Sandwich Recipe

Prep the chicken

Slice the two chicken breasts horizontally so you end up with four thinner cutlets.
Place the chicken on a cutting board and trim any large pieces of fat.
If some pieces look much thicker, cover them with plastic wrap and gently pound them with a meat mallet or rolling pin until they match the others in thickness.

Mix the marinade

In a small bowl, whisk together olive oil, Dijon mustard, lemon juice, garlic, salt, pepper, paprika, and Italian seasoning.
Place the chicken in a shallow dish or zip top bag.
Pour the marinade over the chicken and coat each piece thoroughly.
Chill in the fridge for at least 20 minutes and up to 4 hours while you prep the rest.

Make the Dijon mayo sauce

In another small bowl, stir together mayonnaise, Dijon mustard, honey, lemon juice, salt, and pepper.
Taste and adjust the seasoning; add more honey if you like it sweeter or more Dijon if you want extra tang.
Cover and chill the sauce until you build the sandwiches.

Preheat the grill

Heat a gas grill to medium high heat, about 400°F, or prepare a charcoal grill with a medium hot zone.
Clean the grates with a grill brush so the chicken does not stick.
Oil the grates lightly with a folded paper towel dipped in oil and held with tongs.

Grill the chicken

Remove the chicken from the marinade and let excess drip off.
Place the chicken on the hot grill and close the lid.
Grill the first side for 4 to 5 minutes until you see nice grill marks.
Flip the chicken and grill another 3 to 5 minutes, depending on thickness, until the internal temperature reaches 165°F.
During the last minute of cooking, place a slice of ham and then a slice of Swiss cheese on each piece of chicken so the cheese melts.

Toast the buns

While the cheese melts, split the sandwich rolls.
Brush the cut sides with butter or olive oil.
Place the buns cut side down on the grill for 1 to 2 minutes until they look golden and lightly crisp.
Pull them off the grill before they burn; they toast quickly.

Build the sandwiches

Spread a generous layer of Dijon mayo sauce on the bottom and top halves of each toasted bun.
Add lettuce leaves to the bottom bun, then a slice or two of tomato.
Place the grilled chicken with ham and melted Swiss on top of the tomato.
Add pickle slices if you like that tangy crunch.
Cap with the top bun, press gently, and serve hot while the cheese still stretches.

Recipe Variations

Gluten free: Use gluten free buns and confirm your mustard and deli ham carry gluten free labels.
Low carb: Skip the bun and serve the grilled chicken cordon bleu style over a bed of lettuce with extra sauce as dressing.
Lighter version: Use thin chicken cutlets, light mayo or Greek yogurt in the sauce, and skip the butter on the buns.
Extra smoky: Use smoked Swiss cheese and smoked ham, and add a pinch of chipotle powder to the marinade.
Spicy twist: Add hot sauce or sriracha to the Dijon mayo and sprinkle red pepper flakes on the chicken before grilling.
Kid friendly: Use mild provolone or mozzarella, go light on the Dijon, and serve toppings on the side so kids can build their own.

Ways to Serve Grilled Chicken Cordon Bleu Sandwich Recipe

With baked sweet potato fries and a simple green salad.
With kettle cooked potato chips and crunchy coleslaw.
With roasted veggies and a side of fruit salad.
With grilled corn on the cob and cucumber slices.
With a cup of tomato soup or chicken noodle soup on cooler days.
With a big platter of raw veggies and ranch or yogurt dip.

Storage Success

Store leftover grilled chicken with ham and cheese in an airtight container in the fridge for up to 3 days. Keep the buns and sauce separate so they do not turn soggy. Reheat the chicken gently in a skillet over medium heat or in the oven at 325°F until warm and the cheese softens again. Assemble fresh buns and toppings right before you eat so the sandwich tastes just as good as the first round.
