A crispy, cheesy twist on the classic French dish, this sandwich layers breaded chicken cutlets with ham and Swiss cheese, then grills to golden perfection.
Preheat oven to 400°F. Line a baking sheet with parchment paper.
Set up a breading station: Place flour in a shallow dish. Beat eggs in another dish. In a third dish, combine panko, Parmesan, garlic powder, salt, and pepper.
Dredge each chicken breast in flour, then dip in egg, then coat with panko mixture, pressing gently to adhere.
Heat a large oven-safe skillet over medium-high heat with 2 tbsp oil. Cook chicken 3 minutes per side until golden. Transfer skillet to oven and bake 10 minutes until cooked through (165°F internal).
Meanwhile, in a small bowl, mix Dijon and mayonnaise. Spread cut sides of rolls with the mixture.
Place cooked chicken on bottom buns. Top each with 2 slices ham, then 2 slices Swiss cheese. Place top buns on sandwiches.
Spread softened butter on the outside of each sandwich (top and bottom).
Heat a large skillet or griddle over medium heat. Grill sandwiches 3-4 minutes per side until bread is golden and cheese melts. Serve hot.
Tips
Pound chicken breasts evenly for uniform cooking.
Use a meat thermometer to ensure chicken reaches 165°F.
Sandwiches can be assembled ahead and grilled just before serving.
