In a bowl, whisk together the olive oil, lemon juice, minced garlic, oregano, thyme, salt, and pepper.
Place the chicken breasts in a resealable bag or a shallow dish. Pour the marinade over the chicken, ensuring it is evenly coated. Marinate in the refrigerator for at least 30 minutes, or up to 2 hours.
Preheat your grill to medium-high heat. Clean and lightly oil the grill grates.
Remove chicken from the marinade and discard the used marinade. Grill the chicken for 6-8 minutes per side, or until cooked through and the internal temperature reaches 165°F (74°C).
Let the chicken rest for 5 minutes before slicing and serving.
Notes
Serve with your favorite sides like a fresh salad, roasted vegetables, or rice.
