Pat the chicken breasts dry with a paper towel. This is a crucial step to achieve the desired sear.
In a large bowl, combine the olive oil, garlic powder, onion powder, paprika, salt, black pepper, lemon juice, and fresh herbs. Stir well to create a marinade. Immerse the chicken breasts in the marinade, ensuring they're well-coated. Let them marinate for at least an hour.
Preheat your Blackstone griddle to medium-high heat. Once heated, arrange the chicken breasts on the griddle. They should sizzle upon contact. Cook for 6-7 minutes on each side or until the internal temperature reaches 165°F (74°C).
Once done, let the chicken rest for a few minutes. This step allows the juices to redistribute throughout the chicken, making it even more succulent.
Slice the chicken breasts against the grain and serve them with your favorite sides.
