Pat your chicken thighs dry with paper towels and arrange them on a large cutting board or baking sheet. Combine minced garlic, balsamic vinegar, olive oil, honey, and Dijon mustard in a small bowl, whisking until completely emulsified. This marinade base becomes your secret weapon for flavor development.

Stir dried thyme, dried rosemary, paprika, sea salt, and black pepper into the wet mixture until fragrant and fully incorporated. The dried herbs should bloom slightly as they hydrate in the acidic liquid, releasing their essential oils. Transfer the cozy labor day grilled chicken thighs recipe marinade to a large zip-top bag.

Add all eight chicken thighs to the marinade bag, pressing the mixture around each piece to coat thoroughly on both sides. Squeeze out excess air, seal the bag, and refrigerate for at least thirty minutes or up to four hours if time permits. This step isn't optional—the acid tenderizes the meat while the herbs penetrate deeply.

Preheat your grill to medium-high heat, approximately 375°F, and lightly oil the grates with a folded paper towel. Remove the chicken from the refrigerator and let it sit at room temperature for ten minutes before grilling. Grill skin-side down first for 18-20 minutes without moving, allowing a beautiful golden crust to develop.

Flip each thigh carefully and cook the other side for 15-18 minutes until the internal temperature reaches 165°F when measured in the thickest part. While the chicken cooks, combine the chicken broth with any remaining marinade in a small saucepan and warm it gently—this becomes your finishing sauce.

Transfer cooked chicken to a clean platter and tent loosely with foil to rest for five minutes before serving. Pour the warm sauce mixture over each piece and garnish with freshly chopped parsley for brightness. The residual heat will continue gently cooking the chicken while allowing the marinade to set into a light glaze.
