Instructions
 

  • In a saucepan over low heat, melt the butter. Add the cream cheese and stir until melted. Stir in the heavy cream, whisking continuously until well combined.

  • [If your chicken is not already cooked and shredded] - In a skillet over medium heat, spray with olive oil. Put the chicken breast in the skillet and sear each side for 2-3 minutes. Pour in 1/3 cup of water or chicken broth, reduce heat to medium-low, and cover the skillet with a lid. Check the chicken after 10 minutes with an instant-read thermometer, cook until the chicken reaches 165F/74C. Take it off the heat and let it rest for 5 minutes before shredding.
