Heat the olive oil in a large skillet over medium heat. Fry the chicken breasts in the oil for 3-5 minutes on each side or until golden brown and cooked through. Plate them and keep them in the oven on warm or about 200 degrees.
Melt the butter in the skillet over medium-low heat. Add the garlic and cook for a minute, while stirring.
Stir in the wine and reduce it by half. Whisk in the chicken broth and ranch seasoning, and simmer for about 5 minutes. Whisk in the cream slowly and simmer until reduced by half.
Add the chicken back to the skillet and warm for 2-3 minutes. Spoon the sauce over the top.
