1-First, slice each chicken breast into 2-3 thinner slices about ½ inch thick, and pound them with a meat tenderizer if needed for even cooking. Season both sides of each slice with 2 teaspoons Italian seasoning, salt, and pepper to taste. Brush one side of each slice with 2 tablespoons melted butter to enhance flavor and help with browning.

2-Heat 1 to 2 tablespoons olive oil in a large skillet over medium-high heat, then sear the chicken slices in batches for 4-5 minutes per side until they turn golden brown. Once done, remove the chicken and set it aside. In the same skillet, combine all the sauce ingredients: 10.5 oz cream cheese, 1 ½ cups milk, 1 cup sour cream, ½ teaspoon onion powder, and 1 oz Ranch seasoning mix, stirring over medium heat until everything blends smoothly.

3-Finishing Touches: Let the sauce bubble gently and reduce for about 5 minutes to thicken it up. Return the chicken to the skillet and spoon the sauce over the pieces, then partially cover and simmer for around 10 minutes to let the flavors meld. Serve it hot with baked potatoes or vegetables, spooning extra sauce over the potatoes for a comforting finish.
