Gather all ingredients.

Season chicken on both sides with salt and pepper.

Heat olive oil in a heavy skillet over medium-high heat until it starts to shimmer. Place chicken breasts skin-side down in the skillet. Sprinkle with fresh herbs. Cook until the bottoms are well seared and golden brown, 5 to 6 minutes.

Flip chicken breasts over and continue cooking until an instant-read thermometer inserted into the center of a breast reads 150 degrees F (66 degrees C), about 5 minutes.

Add vinegar and cold butter to the pan with chicken. Shake the pan gently until butter melts and the internal temperature of chicken reads at least 165 degrees F (74 degrees C), 2 to 3 minutes more.

Stir in chicken broth to thin sauce.
