Heat olive oil in a large skillet over medium heat.
Season chicken breasts with salt and pepper on both sides.
Add the chicken to the skillet and cook for 5-7 minutes on each side until golden brown.
Remove the chicken from the skillet and set aside on a plate.
In the same skillet, add the ranch seasoning mix and the chicken broth, stirring to combine.
Stir in the heavy cream and let the mixture simmer for about 5 minutes.
Return the chicken to the skillet, spooning the sauce over the top.
Let it simmer for an additional 5 minutes, garnish with parsley, and serve hot.
