Combine oil, zest, juice, garlic, rosemary, thyme, wine and broth in a glass bowl or dish; add chicken and toss. Cover and refrigerate at least 6 hours or up to overnight.
Off heat, coat a grill or grill pan with cooking spray. Preheat grill to medium-high heat. Remove chicken from marinade (reserve marinade and see note below to make optional glaze) and grill, flipping once, until internal temperature is 165°F, about 3 to 5 minutes per side.
