In a medium bowl, whisk together honey, Dijon mustard, olive oil, apple cider vinegar, minced garlic, salt, black pepper, smoked paprika, and dried thyme until well combined.
Place the chicken thighs in a large resealable plastic bag or a shallow dish. Pour the marinade over the chicken, ensuring all pieces are well coated. Seal the bag or cover the dish and refrigerate for at least 1 hour, or up to 8 hours for more flavor.
Preheat your grill to medium-high heat.
Remove the chicken from the marinade and let any excess drip off. Discard the marinade.
Grill the chicken thighs for 6-7 minutes on each side, or until the internal temperature reaches 165°F.
Remove the chicken from the grill and let it rest for 5 minutes before slicing or serving.
