01 - In a mixing bowl, whisk together the olive oil, lemon juice, minced garlic, dried oregano, smoked paprika, salt, and black pepper until well combined.
02 - Place the chicken breasts in a large resealable plastic bag or a shallow dish. Pour the marinade over the chicken, making sure all pieces are evenly coated. Seal and refrigerate for at least 30 minutes, or up to 4 hours for deeper flavor penetration.
03 - Preheat an outdoor grill or grill pan to medium-high heat. Lightly oil the grates to prevent sticking.
04 - Remove the chicken from the marinade, allowing any excess to drip off. Place the chicken on the hot grill and cook for 6 to 7 minutes per side, until the internal temperature reaches 165°F and the juices run clear.
05 - Transfer the grilled chicken to a cutting board and let it rest for 5 minutes to allow the juices to redistribute before slicing.
06 - Slice and serve the chicken garnished with chopped fresh parsley and lemon wedges alongside grilled vegetables, a fresh salad, or steamed rice.
