Slice each chicken breast in half lengthwise to create 2-3 thinner pieces. Cover with plastic wrap and use the textured side of a meat mallet to pound to ½ inch thickness. Season both sides with salt, pepper, and parsley.

Heat olive oil in a large 12-inch skillet over medium-high heat. Working in batches to avoid overcrowding, sear the chicken for 4-5 minutes per side until a golden crust develops. Remove chicken and set aside.

Turn off the heat and add the white wine to the empty skillet. Then set heat to medium. Use a silicone spatula to scrape up the flavorful browned bits (fond) from the bottom of the pan. Bring to a gentle bubble and reduce for 2 minutes.

Add the minced garlic to the wine and cook for 2-3 more minutes until the liquid has reduced by half. Add the butter and flour, stirring to combine into a paste. Cook for 1-2 minutes to remove the raw flour taste.

Slowly add the prepared sauce mixture in small splashes, stirring continuously to prevent lumps. Bring to a boil, then reduce to a simmer. Let it simmer and reduce for about 8 minutes.

Return the chicken to the skillet and spoon the sauce over the top. Heat through for about 5 minutes or until the sauce reaches your desired thickness. Garnish with additional parsley and serve with mashed potatoes and roasted vegetables.
