Start by patting the chicken breasts dry with paper towels. This step is crucial as it helps the seasoning adhere better and promotes a nice sear.
In a small bowl, combine the all-purpose flour, salt, cracked black pepper, and garlic powder. Dredge each chicken breast in the flour mixture, ensuring they are evenly coated on both sides. Shake off any excess flour.
Heat the olive oil in a skillet over medium-high heat. Once hot, add the chicken breasts carefully to avoid splattering.
Cook the chicken for about 5-7 minutes on one side, or until it develops a golden-brown crust. Flip the chicken using tongs and cook for another 5-7 minutes, or until the internal temperature reaches 165°F (75°C).
Once the chicken is cooked through, squeeze the juice of both lemons over the chicken in the skillet. Make sure to coat each piece well. If you like, you can also add the zest of one lemon for an additional burst of flavor.
Remove the chicken from the skillet and let it rest for a few minutes. This allows the juices to redistribute. Garnish with freshly chopped parsley before serving, and enjoy your Best Lemon-Pepper Chicken alongside your favorite sides.
