Ingredients

Scale
  • 4 boneless, skinless chicken breasts (about 1.5 lbs / 700 g), pounded thin
  • 6–8 thin slices deli ham (about 6 oz / 170 g)
  • 8 oz (225 g) Swiss cheese, sliced or shredded (Gruyère as alternative)
  • 4 tbsp (57 g) unsalted butter, softened
  • 1/4 cup (30 g) all-purpose flour
  • 2 cups (480 ml) whole milk (dairy-free milk optional)
  • 1 tbsp Dijon mustard
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • Salt and freshly cracked black pepper, to taste
  • 1 cup (100 g) panko breadcrumbs
  • 1/2 cup (50 g) grated Parmesan cheese
  • 2 tbsp olive oil or melted butter

Instructions

  1. Preheat oven to 375°F (190°C). Lightly grease a 9×13 inch casserole dish.
  2. Pound chicken breasts to an even thickness of about 1/2 inch (1.3 cm).
  3. Season chicken lightly with salt, pepper, garlic powder, and onion powder on both sides.
  4. Layer ham and Swiss cheese on top of each chicken breast. Roll or fold chicken around fillings or layer flat in casserole dish.
  5. In a medium saucepan, melt butter over medium heat. Whisk in flour and cook 1-2 minutes until bubbly but not browned.
  6. Gradually whisk in milk, stirring constantly to avoid lumps. Simmer and cook until thickened, about 3-5 minutes.
  7. Stir in Dijon mustard, salt, and pepper to taste. Remove from heat and fold in half the shredded Swiss cheese.
  8. Pour creamy sauce evenly over chicken, ham, and cheese in casserole dish.
  9. Mix panko breadcrumbs with grated Parmesan and olive oil or melted butter. Sprinkle evenly over casserole.
  10. Bake uncovered for 30-35 minutes until top is golden and crispy and sauce is bubbling.
  11. Let rest for 5 minutes before serving.

Notes

For gluten-free, substitute all-purpose flour with gluten-free blend and use gluten-free panko breadcrumbs. For extra crispy topping, broil for last 2-3 minutes watching carefully. Lightly searing chicken before assembling adds flavor but is optional. If sauce is too thick before baking, whisk in a splash more milk. Assemble ahead and refrigerate up to 24 hours before baking, adding a few extra minutes to bake time.
