For a flavorful and aromatic pollo a la plancha, try this herb-marinated grilled chicken recipe. To make this dish, you will need the following ingredients: chicken breasts, olive oil, garlic, rosemary, thyme, oregano, salt, and pepper. Start by combining the olive oil, garlic, rosemary, thyme, oregano, salt, and pepper in a bowl to make the marinade. Place the chicken breasts in a resealable plastic bag and pour the marinade over them. Seal the bag and refrigerate for at least 1 hour, or overnight for maximum flavor. Preheat your grill to medium-high heat. Remove the chicken breasts from the marinade and discard the excess marinade. Place the chicken on the grill and cook for about 6-8 minutes per side, or until the internal temperature reaches 165°F. Remove the chicken from the grill and let it rest for a few minutes before serving. The herb marinade infuses the chicken with a fragrant and savory flavor, making it a delicious choice for any occasion.
