In a medium mixing bowl, whisk together the honey, Dijon mustard, olive oil, minced garlic, thyme, salt, and black pepper until smooth.
Pat the chicken thighs dry with paper towels and arrange them in a baking dish in a single layer.
Pour the honey mustard marinade over the chicken thighs, ensuring each piece is coated. Cover and marinate in the refrigerator for at least 30 minutes or up to overnight.
Place the baking dish in the preheated oven and bake for 35-40 minutes, or until the chicken skin is golden brown and the internal temperature reaches 165°F (75°C).
About halfway through baking, baste the chicken thighs with the sauce from the baking dish.
Remove the chicken from the oven and let it rest for 5 minutes. Sprinkle with chopped fresh parsley before serving.
