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