On a flat surface, butterfly the chicken breasts by slicing them horizontally through the middle. Pat them dry with a paper towel. Season them with salt and oregano on both sides. Zest the lemon over one side of the chicken breasts.
Cook:
Heat a large pan over medium-high heat. Once hot, add the oil and heat it up. Place the chicken breasts in the hot pan, lemon zest side down, and cook, without moving them, for 4 minutes on the first side, then once golden and seared, flip them over and continue cooking for an additional 4 to 5 minutes until the chicken breasts’ internal temperature reaches 165F. Squeeze half a lemon over the chicken breasts in the pan and remove them onto a plate.
Serve:
Serve the chicken breasts and squeeze a little more fresh lemon juice.
Notes
Whole chicken breasts, without butterflying them, will take about 7 minutes per side to cook.
