Pat chicken breasts dry with paper towels. If breasts are uneven in thickness, gently pound them between plastic wrap to an even 3/4-inch thickness for uniform cooking.
In a small bowl, combine olive oil, lemon juice, salt-free herb blend, minced garlic, chopped rosemary, thyme leaves, black pepper, and paprika if using.
Coat chicken breasts thoroughly with the herb mixture, ensuring even coverage. For best results, refrigerate for 30 minutes to 2 hours.
Preheat oven to 425°F (218°C).
Heat an oven-safe skillet over medium-high heat. Place marinated chicken breasts in the hot skillet and sear for 2-3 minutes on each side until golden brown.
Transfer the skillet to the preheated oven and roast for 12-15 minutes, until the internal temperature reaches exactly 165°F (74°C).
Remove chicken from oven and let rest, loosely covered with foil, for 5-10 minutes before slicing or serving.
