In a bowl, combine the lemon juice, lemon zest, minced garlic, oregano, olive oil, salt, and pepper to create a marinade.
Add the chicken thighs to the marinade, ensuring they are well coated. Cover and marinate in the refrigerator for at least 30 minutes (or up to 2 hours for deeper flavor).
Preheat your oven to 400°F (200°C).
In a large oven-safe skillet over medium heat, sear the marinated chicken thighs for about 3-4 minutes on each side, until golden brown.
Remove the chicken from the skillet and set aside.
In the same skillet, add the chicken broth, cherry tomatoes, and olives, stirring to combine, then bring to a gentle simmer.
Place the seared chicken thighs back into the skillet, nestling them into the broth mixture.
Transfer the skillet to the preheated oven and bake for 25-30 minutes, or until the chicken is cooked through (internal temperature of 165°F).
Once done, remove from the oven and sprinkle with fresh parsley before serving.
Notes
Marinate the chicken for up to 2 hours for a deeper flavor.
