01 - In a medium bowl, whisk together lemon juice, lemon zest, 3 tablespoons olive oil, garlic, honey, Dijon mustard, thyme, salt, and black pepper until fully combined.
02 - Place chicken breasts in a shallow dish or resealable plastic bag. Pour half of the marinade over chicken, turning to coat evenly. Reserve remaining marinade. Let marinate at room temperature for at least 15 minutes or refrigerate up to 2 hours.
03 - Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Remove chicken from marinade, discarding used marinade. Cook chicken 5 to 6 minutes per side until golden and internal temperature reaches 165°F. Transfer chicken to a plate and loosely cover with foil.
04 - Add reserved marinade and chicken broth to skillet. Bring to a simmer, scraping browned bits from bottom. Cook 3 to 4 minutes until sauce reduces slightly.
05 - Return chicken to skillet, spoon sauce over top, and simmer 2 minutes to warm through.
06 - Plate chicken and garnish with chopped fresh parsley and lemon slices if desired.
