Start by whisking together the olive oil, balsamic vinegar, chopped sage, rosemary, Winter savory (or thyme), salt, pepper, and optional garlic in a shallow baking dish. Make sure everything is evenly blended so each chicken thigh gets coated. I always taste a tiny bit of the marinade (minus the raw garlic) just to check balance — it makes such a difference!
Place the chicken thighs in the marinade and turn them until fully covered. Cover the dish with plastic wrap and let them rest in the fridge. I like to marinate for at least 30 minutes, but a few hours makes the flavors penetrate deeper and yields even juicier results. You can even do this overnight if you’re prepping ahead.
Preheat your oven to 350°F (175°C). Arrange the marinated chicken in the baking dish and pour any remaining juices over the top. Bake for 25–35 minutes, turning once halfway so both sides caramelize lightly. Once the internal temperature reaches 165°F, remove from the oven and let rest for a few minutes before serving — this keeps all the juices locked in!
