Heat a large skillet over medium heat and add the seasoned chicken breasts. Sear each side for about 5-7 minutes until golden brown and cooked throughout.

In the same skillet, reduce heat to low and add cream cheese along with heavy cream. Stir for about 3-5 minutes until melted and blended.

Gradually add grated Parmesan cheese to the sauce while stirring until fully melted and creamy. Season with salt and pepper.

Slice the rested chicken into bite-sized pieces and return it to the skillet with the sauce. Simmer for 1-2 minutes.

Serve immediately, garnishing with chopped parsley or additional Parmesan if desired.
