Instructions:

Preheat your oven to 375°F (190°C). Prepare a baking dish by lightly greasing it with cooking spray.

Place each chicken breast between two pieces of plastic wrap and pound them with a meat mallet or rolling pin until they're about 1/4 inch thick.

Season each chicken breast with salt and pepper. Lay one slice of ham and one slice of Swiss cheese on each breast, then roll them up tightly, securing the ends with toothpicks if necessary.

Set up a breading station: place the flour in one shallow dish, whisk the eggs in another, and put the breadcrumbs in a third dish.

Dredge each chicken roll in flour, then dip it into the beaten eggs, guaranteeing it's fully coated. Finally, roll it in the breadcrumbs, pressing gently to adhere.

Heat olive oil in a large skillet over medium-high heat. Add the breaded chicken rolls and sauté until golden brown on all sides, about 3-4 minutes per side.

Transfer the browned chicken rolls to the prepared baking dish and bake in the preheated oven for 20-25 minutes, or until the chicken is cooked through and the cheese is melted.

Remove from the oven and let rest for a few minutes before slicing. Serve warm.

For best results when cooking Chicken Cordon Bleu, make sure to pound the chicken breasts evenly to guarantee they cook uniformly.

Additionally, don't skip the resting time after baking, as this allows the juices to redistribute, keeping the chicken moist and flavorful. You can also experiment with different types of cheese or add herbs for extra flavor.

Enjoy your homemade Chicken Cordon Bleu!
