Prepare the Chicken:

Preheat the oven to 375°F (190°C). Using a sharp knife, carefully cut a pocket into the side of each chicken breast, making sure not to cut all the way through.

Prepare the Filling:

In a medium bowl, mix together the softened cream cheese, crumbled bacon, and shredded cheddar cheese. Season with salt and pepper to taste.

Stuff the Chicken:

Spoon the cream cheese mixture into each chicken breast pocket. If necessary, secure the edges with toothpicks to keep the filling inside.

Prepare the Breading Station:

Set up three shallow bowls: one with crushed Doritos, one with flour, and one with the beaten eggs and milk mixture.

Bread the Chicken:

Coat each stuffed chicken breast in flour, shaking off any excess. Dip it into the egg mixture, then roll it in the crushed Doritos, pressing the crumbs to adhere to the chicken.

Cook the Chicken:

Heat olive oil in an oven-safe skillet over medium-high heat. Sear the chicken breasts for 2-3 minutes per side until golden brown.

Bake the Chicken:

Transfer the skillet to the preheated oven and bake for 20-25 minutes, or until the chicken is cooked through and the filling is hot and bubbly.

Serve:

Remove the toothpicks and let the chicken rest for 5 minutes before serving. Enjoy the crispy, cheesy, and bacon-filled goodness!
