Pat the chicken breasts dry with paper towels. If the breasts are very thick, gently pound them to an even thickness so they cook evenly.
In a small bowl, combine the black pepper, garlic powder, onion powder, paprika, salt, and lemon zest.
Rub the chicken breasts with olive oil, then coat both sides evenly with the seasoning mixture.
Heat a large skillet over medium-high heat. Add the butter and let it melt.
Place the seasoned chicken breasts in the skillet. Cook for about 5–7 minutes on the first side, depending on thickness.
Flip the chicken and continue cooking until the second side is golden and the chicken reaches an internal temperature of 165°F (74°C).
Reduce the heat to medium-low. Add the minced garlic and cook for about 30 seconds, until fragrant.
Pour the fresh lemon juice into the skillet and spoon the lemon-butter mixture over the chicken.
Cook for another 1–2 minutes, then remove the skillet from the heat.
Let the chicken rest for about 5 minutes before slicing.
Garnish with fresh parsley and serve with lemon wedges.
