Chicken Cordon Bleu is lightly breaded and baked chicken breasts stuffed with thinly sliced deli ham and gruyere cheese, topped with a creamy mustard sauce.
Preheat the oven to 375°F.
On a second plate, whisk the eggs and water together.
On a third plate combine breadcrumbs, butter, salt, and garlic. Mix until well combined.
In a medium saucepan, whisk together the heavy cream and cornstarch until smooth. Set over medium heat, and whisk constantly until the mixture starts to thicken. Add the mayonnaise and the dijon mustard and stir to combine.
