Preheat oven to 400 degrees F. Spray a 9x13-inch baking dish with cooking spray. Set aside.
In a large freezer ziplock bag, add the flour, salt and pepper. Place 4 chicken halves at a time, into the bag, and shake well to fully coat the chicken. Repeat with other 4 halves until well coated.
In a heavy-bottomed skillet, pour 2 Tablespoons of olive oil in the bottom. Heat oil over medium-high heat. Brown the coated chicken, on both sides, until nice and golden brown. (You do not need to cook it all the way through. It will finish cooking in the oven.) Transfer the chicken to the prepared baking dish.
Combine the thyme, oregano, rosemary, parsley and garlic salt into the chicken broth and remaining olive oil. Stir well. Baste chicken with the broth mixture, then place in the oven uncovered.
Bake for 15 minutes (and continue to baste every 5 minutes while it cooks.) Chicken is done when the internal temperature reaches 165 degrees F. Do not overcook. Serve warm and enjoy!
