Place the chicken breasts on a cutting board and pat them dry with paper towels.
Using a sharp knife and a meat mallet or heavy pan, gently pound each chicken breast to an even thickness — about ½ inch — until they feel tender and slightly flattened.
Sprinkle the chicken generously with salt, black pepper, and smoked paprika, making sure to season both sides evenly.
Heat a skillet over medium-high heat and add the olive oil, letting it shimmer and just begin to smoke slightly.
Carefully place the seasoned chicken breasts into the hot skillet, laying them away from you to avoid splatters. Sear without moving for about 4-6 minutes until they develop a golden-brown crust.
Flip the chicken using tongs or a spatula, then cook the other side for another 4-6 minutes until the exterior is golden and the juices run clear when pierced with a knife.
Check the internal temperature with an instant-read thermometer; it should read 74°C (165°F) for perfect doneness.
Remove the chicken from the skillet and let it rest on a plate for about 5 minutes, allowing the juices to redistribute and keep the meat moist.
While resting, drizzle lemon juice or sprinkle lemon zest over the chicken, and sprinkle chopped fresh herbs on top for added flavor and aroma.
Slice the chicken against the grain, revealing a juicy interior with a crisp exterior, ready to serve alongside your favorite sides.
