Pat the chicken breasts dry with paper towels to ensure a good sear and set them on a clean cutting board.
In a small bowl, whisk together lemon juice, minced garlic, smoked paprika, olive oil, and a pinch of salt and pepper to create the marinade.
Pour the marinade over the chicken breasts, making sure they are well coated. Cover and refrigerate for at least 30 minutes to let flavors infuse and the chicken stay juicy.
Preheat your grill or grill pan to medium-high heat, about 200°C (390°F). Lightly oil the grates with a basting brush or paper towel dipped in oil to prevent sticking.
Place the marinated chicken breasts on the hot grill, listening for a sizzle as they make contact. Close the lid and cook for 6-7 minutes until the underside develops deep golden grill marks and a slight char.
Use tongs to flip the chicken breasts carefully, then cook for another 6-7 minutes on the second side, watching for similar grill marks and a fragrant smoky aroma.
Insert a probe thermometer into the thickest part of the chicken to check for an internal temperature of 75°C (165°F). Once reached, remove the chicken from the grill and transfer to a plate.
Tent the chicken loosely with foil and let it rest for 5 minutes. This allows the juices to redistribute, ensuring each bite is tender and juicy.
Slice the chicken against the grain into thin strips or serve whole, garnished with chopped fresh herbs and a squeeze of lemon for added brightness.
