Adjust your oven rack to lower-middle position and preheat your oven to 325 degrees.
Prepare a rimmed baking sheet with tinfoil and a rack lightly coated in cooking spray.
Holding onto one piece at a time use your finger to gently separate the skin from the breast meat, leaving the edges of the skin attached to the chicken breast. Lift the skin like it's an open door.
Using your salt shaker or a pinch of salt that is about ½ teaspoon in size, sprinkle salt, as evenly as possible, all over the surface of the breast, not the skin. Once salted, place your skin back on top of the breast.
Using the tip of a sharp knife or something sharp, poke at least 6 small holes through the skin. Depending on the size of your chicken breasts, up to 10 holes.
Place all of the breasts on your prepared baking sheet.
Bake until the meat has an internal temperature that registers 165 degrees, between 35 and 45 minutes.
Grab your largest skillet. Turn your oven on low and heat your skillet for five minutes on medium heat.
Add oil and make sure there is oil everywhere in your skillet. Add breasts, skin side down.
Increase your heat to medium high.
Do not move the pieces for the first three minutes. Keep watching for the skin to darken and crisp. No more than 5 minutes.
Lean each chicken breast to the side of the skillet so the fattest side of the breast is facing downwards on your skillet.
Cook until skin looks brown and crispy, another couple minutes, maximum.
Allow to rest on a plate or cutting board for 5 minutes before serving.
